Jacky: /* p-x-dietary-preference */ add self for preference

== h-as-* ==
ActivityStreams-based post types, usually done in combination with h-entry.

=== Usage ===

* [http://glennjones.net/ glennjones.net] ([http://glennjones.net/notes/2015-07-11 example: h-as-note])

Formerly:
* tantek.com - used to (~2014) use h-as-article and h-as-note but decided this type of explicit typing was unnecessary from a format perspective so dropped them. [[User:Tantek|Tantek]] 19:52, 11 July 2015 (UTC)

=== Usage ===

* [http://glennjones.net/ glennjones.net] ([http://glennjones.net/notes/2015-07-11 example])
* [http://tantek.com/ tantek.com] ([http://tantek.com/2015/191/t1/indiewebcamp-pre-party example])

how is this different from [[h-card]]'s p-nickname ? [[User:Kevin Marks|Kevin Marks]]

Jacky: /* Experiments */ add rust

{{DISPLAYTITLE:microformats2}}
Welcome to the microformats2 home page.

== Summary ==
Microformats2 is the latest version of microformats, the simplest way to markup structured information in HTML. Microformats2 improves ease of use and implementation for <em>both</em> authors (publishers) and developers ([[microformats2-parsing|parser]] implementers).

Microformats2 replaces and supersedes both classic microformats (sometimes called microformats1), as well as incorporates lessons learned from [[microdata]] and [[RDFa]].

=== simple microformats2 examples ===
Here are a few <span id="simple_microformats_2_examples">simple microformats2 examples</span> along with canonical [[JSON]].

=== details from examples ===
Details demonstrated by the examples:
# The JSON <code>"type"</code> uses the full microformat root class name (e.g. <code>"h-card"</code>) for consistent identification.
# all properties are optional and syntactically plural with parsed values provided in document order; particular microformats (and applications there-of) may apply specific/singular semantics to first value of a property.

=== microformats2 design ===

microformats2 has the following key design aspects:

; Prefixes for class names
: All microformats class names use prefixes. Prefixes are '''syntax independent from vocabularies''', which are developed separately.
* <code>h-*</code> for root class names (e.g. <code>h-card</code>)
* <code>p-*</code> for plain text properties (e.g. <code>p-name</code>)
* <code>u-*</code> for URL properties (e.g. <code>u-photo</code>)
* <code>dt-*</code> for date/time properties (e.g. <code>dt-bday</code>)
* <code>e-*</code> for embedded markup properties (e.g. <code>e-note</code>)<br />

See [[microformats2-prefixes]] for more details.

; Flat sets of optional properties
: All microformats consist of a root, and a collection of properties. Hierarchical data is represented with nested microformats, typically as property values themselves. Properties are all optional and potentially multivalued (applications needing a singular semantic may use first instance).

; Single class markup for common uses
: Common simple markup patterns require only a single microformat root class name, which parsers use to find a few generic properties: <code>name</code>, <code>url</code>, <code>photo</code>. The simple microformats2 examples above demonstrate these.

----

Parsing each prefix (including generating canonical JSON) is detailed step-by-step in:
* The '''[[microformats2-parsing|microformats2 parsing specification]]'''

'''Note:''' Most properties are specified and used with a single specific prefix (or occasionally two or three) that is self-evident from context. However, any parsing prefix can be used with any property, especially if you find a good reason to do so!

== v2 vocabularies ==
Status: '''<span id="draft_v2_vocabularies">draft</span>'''. Please review and provide feedback in [[IRC]].
* [[h-adr]]
* [[h-card]]
* [[h-entry]]
* [[h-event]]
* [[h-feed]]
* [[h-geo]]
* [[h-item]]
* [[h-listing]]
* [[h-product]]
* [[h-recipe]]
* [[h-resume]]
* [[h-review]]
* [[h-review-aggregate]]

See below for vocabulary summaries.

=== h-adr ===
{{main|h-adr}}

The '''h-adr''' microformat is for marking up structured locations such as addresses, physical and/or postal. This is an update to [[adr]].

root class name: '''<code>h-adr</code>'''<br/>
profile/itemtype: <nowiki>http://microformats.org/profile/h-adr</nowiki>

properties:
* '''<code>p-post-office-box</code>'''
* '''<code>p-extended-address</code>'''
* '''<code>p-street-address</code>'''
* '''<code>p-locality</code>'''
* '''<code>p-region</code>'''
* '''<code>p-postal-code</code>'''
* '''<code>p-country-name</code>'''
* '''<code>p-label</code>''' - new in [[vCard4]] ([[RFC6350]])
* '''<code>p-geo</code>''' (or '''<code>u-geo</code>''' with a RFC 5870 geo: URL) - new in [[vCard4]] ([[RFC6350]])
* '''<code>p-latitude</code>''' - new in [[vCard4]] ([[RFC6350]] from RFC 5870)
* '''<code>p-longitude</code>''' - new in [[vCard4]] ([[RFC6350]] from RFC 5870)
* '''<code>p-altitude</code>''' - new in [[vCard4]] ([[RFC6350]] from RFC 5870)

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-adr" is found, don't look for an "adr" on the same element.

compat root class name: <code id="adr">adr</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)
* <code>post-office-box</code>
* <code>extended-address</code>
* <code>street-address</code>
* <code>locality</code>
* <code>region</code>
* <code>postal-code</code>
* <code>country-name</code>

=== h-card ===
{{main|h-card}}

The '''h-card''' microformat is for marking up people and organizations. This is an update to [[hCard]].

root class name: '''<code>h-card</code>'''<br/>

* '''<code>p-locality</code>'''
* '''<code>p-region</code>'''
* '''<code>p-postal-code</code>'''
* '''<code>p-country-name</code>'''
* '''<code>p-label</code>'''
* '''<code>p-geo</code>''' or '''<code>u-geo</code>''' with a RFC 5870 geo: URL, new in [[vCard4]] ([[RFC6350]])
* '''<code>p-latitude</code>'''
* '''<code>p-longitude</code>'''
* '''<code>p-altitude</code>''' - new in [[vCard4]] ([[RFC6350]] from RFC 5870)
* '''<code>p-tel</code>'''
* '''<code>p-note</code>'''
* '''<code>dt-bday</code>'''
* '''<code>u-key</code>'''

* '''<code>p-gender-identity</code>''' new in [[vCard4]] ([[RFC6350]])
* '''<code>dt-anniversary</code>''' new in [[vCard4]] ([[RFC6350]])
* ...

Reserved properties: (properties not used much (if at all) in practice)
* '''<code>p-organization-name</code>'''
* '''<code>p-organization-unit</code>'''
* '''<code>p-tz</code>'''
* '''<code>dt-rev</code>'''
* ...

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-card" is found, don't look for a "vcard" on the same element.

compat root class name: <code id="vcard">vcard</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)
* <code>fn</code> - parse as '''<code>p-name</code>'''
* <code>honorific-prefix</code>
* <code>given-name</code>
* <code>additional-name</code>
* <code>family-name</code>
* <code>honorific-suffix</code>
* <code>nickname</code>
* <code>email</code> - parse as '''u-'''
* <code>logo</code> - parse as '''u-'''
* <code>photo</code> - parse as '''u-'''
* <code>url</code> - parse as '''u-'''
* <code>uid</code> - parse as '''u-'''
* <code>category</code>

* <code>tel</code>
* <code>note</code>
* <code>bday</code> - parse as '''dt-'''
* <code>key</code> - parse as '''u-'''
* <code>org</code>
* <code>organization-name</code>
* <code>organization-unit</code>
* <code>title</code> - parse as '''p-job-title'''
* <code>role</code>
* ...

Reserved: (backward compat properties that parsers {{may}} implement, if they do, they {{must}} implement in this way:
* <code>tz</code>
* <code>rev</code> - parse as '''dt-'''
* ...

Note: use of 'value' within 'tel' should be automatically handled by the support of the [[value-class-pattern]]. And for now, the 'type' subproperty of 'tel' is dropped/ignored. If there is demonstrable documented need for additional tel types (e.g. fax), we can introduce new flat properties as needed (e.g. p-tel-fax).

=== h-entry ===
{{main|h-entry}}

The '''h-entry''' microformat is for marking up syndicatable content such as blog posts, notes, articles, comments, photos and similar. This is an update to [[hAtom]].

root class name: '''<code>h-entry</code>'''<br/>
profile/itemtype: <nowiki>http://microformats.org/profile/h-entry</nowiki>

properties:
* '''<code>p-name</code>''' (was p-entry-title, see issues)
* '''<code>p-summary</code>''' (was p-entry-summary, see issues)
* '''<code>e-content</code>''' (was e-entry-content, see issues)
* '''<code>dt-published</code>'''
* '''<code>dt-updated</code>'''
* '''<code>p-author</code>'''
* '''<code>p-category</code>'''
* '''<code>u-url</code>'''
* '''<code>u-uid</code>'''
* '''<code>p-geo</code>'''
* '''<code>p-latitude</code>'''
* '''<code>p-longitude</code>'''

This is an update to [[hAtom]].

Brainstorming:

The following properties are proposed additions to h-entry above and beyond what hAtom (or Atom) provides, based on various existing link preview markup conventions:
* '''<code>u-photo</code>'''
* '''<code>u-audio</code>''' - consider special u- parsing rules for <code><audio></code>
* '''<code>u-video</code>''' - consider special u- parsing rules for <code><video></code>
* '''<code>u-in-reply-to</code>''' - for links to other posts that this post is a reply to (comment regarding, etc.)

Backward compatibility:

(*)hAtom-specific implementations that perform custom display or translation (e.g. to Atom XML) {{should}} prefer <code>p-name</code> over <code>p-entry-title</code>, and use <code>p-entry-title</code> value(s) as a fallback if there is no <code>p-name</code>.

For hAtom backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-entry" is found, don't look for a "hentry" on the same element.

compat root class name: <code id="hentry">hentry</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)
* <code>entry-title</code> - parse as '''<code>p-name</code>'''
* <code>entry-summary</code>
* <code>entry-content</code> - parse as '''e-'''
* <code>published</code> - parse as '''dt-'''
* <code>updated</code> - parse as '''dt-'''
* <code>author</code> - including compat root <code>vcard</code> in the absence of <code>h-card</code>
* <code>category</code>
* <code>geo</code> - parse as '''<code>p-geo h-geo</code>''' including compat root <code>geo</code>
* <code>latitude</code>
* <code>longitude</code>
* ...

<span id="h-entry-faq">FAQ:</span>
<div class="discussion">
* '''What is the <code>p-name</code> of a [http://indiewebcamp.com/note note]?'''
** A few options, from simplest to most detailed.
*** '''same as the p-content/e-content''' property.
*** '''same as the <code>title</code> element''' on the note permalink post page. When publishing a note on its own permalink post page, the contents of the note are likely abbreviated for the title of the page. The same abbreviation can be used for the p-name.
*** '''first sentence of the p-content/e-content''' property. It may be better for [http://indiewebcamp.com/syndication syndication] and [[link-preview]] purposes to provide just the first sentence of the note as the <code>p-name</code>. Similarly if only a portion of the content is syndicated to other sites, that portion can be marked up as the <code>p-summary</code>.
* ...
</div>

Resolved Issues:
* 2012-245 Resolved. See [http://krijnhoetmer.nl/irc-logs/microformats/20120830#l-120 2012-243 IRC discussion/consensus] for:
** Use '''<code>p-summary</code> instead of <code>p-entry-summary</code>'''. The historical semantic of "entry-summary" is not different from "summary" in any significant (or discernible way). Collapsing the two will simplify the overall microformats2 vocabularies further. In microformats2, entry-summary is no more.
** Use '''<code>e-content</code> instead of <code>e-entry-content</code>'''. Same point and advantage. In microformats2, entry-content is no more.
** '''drop <code>p-entry-title</code>'''. Unnecessary and subsumed by "p-name". Would consider move to backward compat only if cases are presented - known publishing uses are expected to be updated shortly.

=== h-event ===
{{main|h-event}}

The '''h-event''' microformat is for marking up events. This is an update to [[hCalendar]].

root class name: '''<code>h-event</code>'''<br/>
profile/itemtype: <nowiki>http://microformats.org/profile/h-event</nowiki>

properties:
* '''<code>p-name</code>'''
* '''<code>p-summary</code>'''(*)

* '''<code>u-url</code>'''
* '''<code>p-category</code>'''
* '''<code>p-location</code>'''
* '''<code>p-geo</code>'''
* '''<code>p-latitude</code>'''
* '''<code>p-longitude</code>'''
* ...

This is an update to [[hCalendar]].

(*)hCalendar-specific implementations that perform custom display or translation (e.g. to iCalendar .ics) {{should}} prefer <code>p-name</code> over <code>p-summary</code>, and use <code>p-summary</code> value(s) as a fallback if there is no <code>p-name</code>.

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-event" is found, don't look for a "vevent" on the same element.

compat root class name: <code id="vevent">vevent</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)
* <code>summary</code> - parse as '''<code>p-name</code>'''
* <code>dtstart</code> - parse as '''<code>dt-start</code>'''

* <code>duration</code> - parse as '''<code>dt-duration</code>'''
* <code>description</code>
* <code>url</code> - parse as '''u-'''
* <code>category</code>
* <code>location</code> - including compat root <code>vcard</code> in the absence of <code>h-card</code>, and compat root <code>adr</code> in the absence of <code>h-adr</code>

* <code>latitude</code>
* <code>longitude</code>
* ...

=== h-geo ===
{{main|h-geo}}

The '''h-geo''' microformat is for marking up WGS84 geophysical coordinates. This is an update to [[geo]].

root class name: '''<code>h-geo</code>'''<br/>
profile/itemtype: <nowiki>http://microformats.org/profile/h-geo</nowiki>

properties:
* '''<code>p-latitude</code>'''
* '''<code>p-longitude</code>'''
* '''<code>p-altitude</code>''' - new in [[vCard4]] ([[RFC6350]] from RFC 5870)

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-geo" is found, don't look for an "geo" on the same element.

compat root class name: <code id="geo">geo</code>
properties: (parsed as '''p-''' plain text unless otherwise specified)
* <code>latitude</code>
* <code>longitude</code>

=== h-item ===
{{main|h-item}}

The '''h-item''' microformat is for marking up the item of an [[h-review]] or [[h-product]]. This is an update to part of [[hReview]].

root class name: '''<code>h-item</code>'''<br/>
profile/itemtype: <nowiki>http://microformats.org/profile/h-item</nowiki>

properties:
* '''<code>p-name</code>'''
* '''<code>u-photo</code>'''
* '''<code>u-url</code>'''

Note: in practice, due to the microformats2 implied property rules, it is expected that most uses of "h-item" won't require any explicit properties at all (since microformats2 parsers will infer name, photo, and url properties from the structure of the element with "h-item" and its contained content/elements if any).

=== h-product ===
{{main|h-product}}

The '''h-product''' microformat is for marking up products. This is an update to [[hProduct]].

root class name: '''<code>h-product</code>'''<br/>

* '''<code>p-category</code>''' - freeform categories or tags applied to the item by the reviewer
* '''<code>e-description</code>'''
* '''<code>u-url</code>''' - URL of the product
* '''<code>u-identifier</code>''' - includes type (e.g. mpn, upc, isbn, issn, sn, vin, sku etc.) and value.
* '''<code>p-review</code>''' - a review of the product, can also be a nested <code>h-review</code>
* '''<code>p-price</code>''' - retail price of the product

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-product" is found, don't look for an "hproduct" on the same element.

compat root class name: <code id="hproduct">hproduct</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)

Note: [[hProduct]] has at least one experimental property which has real world adoption due to [[Google]] and [[Bing]] search support of hProduct. Currently this is: '''price'''

=== h-recipe ===
{{main|h-recipe}}

The '''h-recipe''' microformat is for marking up food recipes. This is an update to [[hRecipe]].

* '''<code>dt-published</code>''' - the date the recipe was published
* '''<code>p-nutrition</code>''' - nutritional information like calories, fat, dietary fiber etc.
* ...

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-recipe" is found, don't look for an "hrecipe" on the same element.

compat root class name: <code id="hrecipe">hrecipe</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)

* <code>experience</code> - including compat root <code>vevent</code> in the absence of <code>h-event</code>
* <code>skill</code>
* <code>affiliation</code> - including compat root <code>vcard</code> in the absence of <code>h-card</code>

Note: skill has a [[hresume-skill-brainstorm|proposed expansion into competency]] with explicit summary, rating and/or duration components. Based on existing real world adoption, we should consider an h-competency vocabulary with p-summary, p-rating, and dt-duration properties.

=== h-review ===
{{main|h-review}}

The '''h-review''' microformat is for marking up reviews. This is an update to [[hReview]]. See also [[h-item]].

root class name: '''<code>h-review</code>'''<br/>
profile/itemtype: <nowiki>http://microformats.org/profile/h-review</nowiki>

properties:
* '''<code>p-name</code>''' - name of the review
* '''<code>p-item</code>''' - thing been reviewed i.e. business or person (h-card), event (h-event), place (h-adr or h-geo), product (h-product), website, url, or other item ([[h-item]]).
* '''<code>p-reviewer</code>''' - person who authored the review
* '''<code>dt-reviewed</code>''' - date time of when the review was written
* '''<code>p-rating</code>''' - value from 1-5 indicating a rating for the item (5 best).
* '''<code>p-best</code>''' - define best rating value. can be numerically lower than worst.
* '''<code>p-worst</code>''' - define worst rating value. can be numerically higher than best.
* '''<code>e-description</code>''' - the full text written evaluation and opinion of the reviewer
* '''<code>p-category</code>''' - freeform categories or tags applied to the item by the reviewer
* '''<code>u-url</code>''' - URL of the review

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-review" is found, don't look for an "hreview" on the same element.

compat root class name: <code id="hreview">hreview</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)
* <code>summary</code> parse as '''<code>p-name</code>'''
* <code>fn</code> - parse as '''p-name''' of the item being reviewed (p-item h-item p-name)
* <code>photo</code> - parse as '''u-photo''' of the item being reviewed (p-item h-item u-photo)
* <code>url</code> - parse as '''u-url''' of the item being reviewed (p-item h-item u-url)
* <code>reviewer</code> - including compat root vcard in the absence of h-card
* <code>dtreviewed</code> - parse as '''dt-'''
* <code>rating</code>
* <code>best</code>
* <code>worst</code>
* <code>description</code> - parse as '''e-'''
* <code>rel="tag"</code> - parse as '''p-category'''
* <code>rel="self bookmark"</code> - parse as '''u-url'''. note that <code>rel</code> attribute value is treated as a space separated set, thus any presence of "self" and "bookmark" within such a set in a rel value is accepted.

Note: The [[hReview]] format has three properties which make use of <code>rel</code> attribute, these are <code>tag</code>, permalink (via the <code>self</code> and <code>bookmark</code> values) and <code>license</code>. Microformats2 parsers {{should}} map these URLs into the page scoped rel collection.

=== h-review-aggregate ===
{{main|h-review-aggregate}}

The '''h-review-aggregate''' microformat is for marking up aggregate reviews of a single item. This is an update to [[hreview-aggregate]]. See also [[h-item]].

root class name: '''<code>h-review-aggregate</code>'''<br/>
profile/itemtype: <nowiki>http://microformats.org/profile/h-review-aggregate</nowiki>

properties:
* '''<code>p-name</code>''' - name of the review
* '''<code>p-item</code>''' - thing been reviewed i.e. business or person (h-card), event (h-event), place (h-adr or h-geo), product (h-product), website, url, or other item (h-item).
* '''<code>p-rating</code>''' - value from 1-5 indicating average rating for the item (5 best).
* '''<code>p-best</code>''' - define best rating value. can be numerically lower than worst.
* '''<code>p-worst</code>''' - define worst rating value. can be numerically higher than best.
* '''<code>p-count</code>''' - number of reviews aggregated.
* '''<code>p-votes</code>''' - number of reviewers who have rated the product, thus contributing to the average rating.
* '''<code>p-category</code>''' - freeform categories or tags applied to the item by the reviewer
* '''<code>u-url</code>''' - URL of the review

For backward compatibility, microformats2 parsers {{should}} detect the following root class name and property names. A microformats2 parser may use existing classic microformats [[parsers]] to extract these properties. If an "h-review-aggregate" is found, don't look for an "hreview-aggregate" on the same element.

compat root class name: <code id="hreview-aggregate">hreview-aggregate</code><br/>
properties: (parsed as '''p-''' plain text unless otherwise specified)
* <code>summary</code> parse as '''<code>p-name</code>'''
* <code>fn</code> - parse as '''p-name''' of the item being reviewed (p-item h-item p-name)
* <code>photo</code> - parse as '''u-photo''' of the item being reviewed (p-item h-item u-photo)
* <code>url</code> - parse as '''u-url''' of the item being reviewed (p-item h-item u-url)
* <code>rating</code>
* <code>best</code>
* <code>worst</code>
* <code>count</code>
* <code>votes</code>
* <code>rel="tag"</code> - parse as '''p-category'''
* <code>rel="self bookmark"</code> - parse as '''u-url'''. note that <code>rel</code> attribute value is treated as a space separated set, thus any presence of "self" and "bookmark" within such a set in a rel value is accepted.

=== v2 vocab notes ===
Notes:
* All v2 vocabularies are defined as flat lists of properties of an object/item, and thus can be used in microformats-2 syntax as shown, or in microdata items, or RDFa. The microformats-2 property parsing prefixes "p-", "u-", "dt-", "e-" are omitted when using defined properties in microdata itemprop and RDFa property as those syntaxes have their own element-specific parsing rules.
* Profile URLs are provided for use with the HTML4 <code>profile</code> attribute, microdata <code>itemtype</code> attribute, and RDFa <code>vocab</code> & <code>typeof</code> attributes (though the latter requires slicing off the trailing segment of the profile for the typeof attribute, and leaving the rest in vocab).
* microformats2 properties may also be explicitly bound as URIs using [[rel-profile]], the [[html5-profile]] attribute proposal, or an HTML5 'vocab' attribute instead. If URI bound terms are important to you, please express interest on [[rel-profile]], [[html5-profile]], or contribute to an [[html5-vocab]] draft.

=== v2 vocab to-do ===
To do:
* write a simple tutorial for creating/getting started with microformats-2 markup for new content
* examples in each h-* spec listed above of how to embed other microformats in them
* actual profile documents at <nowiki>http://microformats.org/profile/h-*</nowiki> URLs mentioned above.
* Provide any necessary microdata-specific language as needed (e.g. to be comparably understandable to the [http://www.whatwg.org/specs/web-apps/current-work/#vcard sample vCard4/hCard1 microdata vocabulary]. Also provide any necessary RDFa-specific language as needed. Both preferably in a generic vocabulary-independent way.
* write a porting guide mapping v1 property -> v2 property
** use-case: simple search/replace in templates (e.g. in case web author doesn't remember existing microformats vocabs and where they used them).
** advise using *both* in existing templates (e.g. in case some CSS depends on the existing microformats)
* analyzie/document how well the microformats2 model and vocabularies satisfy the [http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-May/019681.html use-cases used to design/create microdata].

== combining microformats ==
Since microformats2 uses simple flat sets of properties for each microformat, multiple microformats are combined to indicate additional structure.

=== h-event location h-card ===
Events commonly have venue information with additional structure, like address information. For example:

<source lang=html4strict>
<div class="h-event">
<a class="p-name u-url" href="http://indiewebcamp.com/2012">
IndieWebCamp 2012
</a>
from <time class="dt-start">2012-06-30</time>
to <time class="dt-end">2012-07-01</time> at
<span class="p-location h-card">
<a class="p-name p-org u-url" href="http://geoloqi.com/">
Geoloqi
</a>,
<span class="p-street-address">920 SW 3rd Ave. Suite 400</span>,
<span class="p-locality">Portland</span>,
<abbr class="p-region" title="Oregon">OR</abbr>
</span>
</div>
</source>

The nested h-card used to structure the p-location of the h-event is represented as a structured value for "location" in the JSON, which has an additional key, "value" that represents the plain text version parsed from the p-location.

Parsed JSON:
<source lang=javascript>
{
"items": [{
"type": ["h-event"],
"properties": {
"name": ["IndieWebCamp 2012"],
"url": ["http://indiewebcamp.com/2012"],
"start": ["2012-06-30"],
"end": ["2012-07-01"],
"location": [{
"value": "Geoloqi",
"type": ["h-card"],
"properties": {
"name": ["Geoloqi"],
"org": ["Geoloqi"],
"url": ["http://geoloqi.com/"],
"street-address": ["920 SW 3rd Ave. Suite 400"],
"locality": ["Portland"],
"region": ["Oregon"]
}
}]
}
}]
}
</source>

Questions:
<div class="discussion">
* Should the nested hCard be present also as a top-level item in the JSON? - [[User:Tantek|Tantek]] 02:02, 19 June 2012 (UTC)
** My current (2012-243) leaning is no. - [[User:Tantek|Tantek]] 18:53, 30 August 2012 (UTC)
** If so, how do we avoid expansion of the JSON geometrically proportional to the depth of microformat nesting? (Or do we not worry about it?)
* Should there be a canonical hierarchical JSON and a canonical flattened JSON? - [[User:Tantek|Tantek]] 02:02, 19 June 2012 (UTC)
** My current (2012-243) leaning is no, we stick with one canonical JSON for uf2 which is hierarchical. - [[User:Tantek|Tantek]] 18:53, 30 August 2012 (UTC)
** If so, should the flattened JSON have references from properties to nested microformats that have been pushed to the top level per flattening? - [[User:Tantek|Tantek]] 02:02, 19 June 2012 (UTC)
*** If so, what convention does/do JSON follow for such synthetic local reference identifiers? - [[User:Tantek|Tantek]] 02:02, 19 June 2012 (UTC)
</div>

Notes:
* The 'location' value reflects the visible text of its element, including spaces and punctuation, as well as the state abbreviation 'OR'. The 'h-card' property values are only what is marked up, and thus include structure values without extra punctuation, and the state takes the expanded form from the <code>title</code> attribute of its <code><abbr></code> element.

=== h-card org h-card ===
People often publish information general to their company rather than specific to them, in which case, they may wish to encapsulate that in separately nested microformat. E.g. here is a simple h-card example with org property:

[http://blog.lizardwrangler.com Mitchell Baker] (Mozilla Foundation)

with source:
<source lang=html4strict>
<div class="h-card">
<a class="p-name u-url"
href="http://blog.lizardwrangler.com/"
>Mitchell Baker</a>
(<span class="p-org">Mozilla Foundation</span>)
</div>
</source>

Parsed JSON:
<source lang=javascript>
{
"items": [{
"type": ["h-card"],
"properties": {
"name": ["Mitchell Baker"],
"url": ["http://blog.lizardwrangler.com/"],
"org": ["Mozilla Foundation"]
}
}]
}
</source>

Sometimes such organization affiliations are hyperlinked to the website of the organization:

[http://blog.lizardwrangler.com Mitchell Baker] ([http://mozilla.org/ Mozilla Foundation])

You can mark that up with a nested h-card:
<source lang=html4strict>
<div class="h-card">
<a class="p-name u-url"
href="http://blog.lizardwrangler.com/"
>Mitchell Baker</a>
(<a class="p-org h-card"
href="http://mozilla.org/"
>Mozilla Foundation</a>)
</div>
</source>

Parsed JSON:
<source lang=javascript>
{
"items": [{
"type": ["h-card"],
"properties": {
"name": ["Mitchell Baker"],
"url": ["http://blog.lizardwrangler.com/"],
"org": [{
"value": "Mozilla Foundation",
"type": ["h-card"],
"properties": {
"name": ["Mozilla Foundation"],
"url": ["http://mozilla.org/"]
}
}]
}
}]
}
</source>

Note: the nested h-card has implied 'name' and 'url' properties, just like any other root-class-name-only h-card on an <code><a href></code> would.

'''FOR PARSERS ONLY:'''

The nested 'h-card' could be marked up as an 'h-org' as well, which adds it to the nested microformat's type array, all as part of the property specified by the 'p-org'.

<source lang=html4strict>
<div class="h-card">
<a class="p-name u-url"
href="http://blog.lizardwrangler.com/"
>Mitchell Baker</a>
(<a class="p-org h-card h-org"
href="http://mozilla.org/"
>Mozilla Foundation</a>)
</div>
</source>

Parsed JSON:
<source lang=javascript>
{
"items": [{
"type": ["h-card"],
"properties": {
"name": ["Mitchell Baker"],
"url": ["http://blog.lizardwrangler.com/"],
"org": [{
"value": "Mozilla Foundation",
"type": ["h-card", "h-org"],
"properties": {
"name": ["Mozilla Foundation"],
"url": ["http://mozilla.org/"]
}
}]
}
}]
}
</source>

'''FOR PARSERS ONLY:'''

Without a property class name like 'p-org' holding all the nested objects together, we need to introduce another array for nested children (similar to the existing DOM element notion of children) of a microformat that are not attached to a specific property:

<source lang=html4strict>
<div class="h-card">
<a class="p-name u-url"
href="http://blog.lizardwrangler.com/"
>Mitchell Baker</a>
(<a class="h-org h-card"
href="http://mozilla.org/"
>Mozilla Foundation</a>)
</div>
</source>

Parsed JSON:
<source lang=javascript>
{
"items": [{
"type": ["h-card"],
"properties": {
"name": ["Mitchell Baker"],
"url": ["http://blog.lizardwrangler.com/"]
},
"children": [{
"type": ["h-card","h-org"],
"properties": {
"name": ["Mozilla Foundation"],
"url": ["http://mozilla.org/"]
}
}]
}]
}
</source>

Since there's no property class name on the element with classes 'h-card' and 'h-org', the microformat representing that element is collected into the children array.

Such a nested microformat implies some relationship (containment, being related), but is not as useful as if the nested microformat was a specific property of its parent.

For this reason it's recommended that authors should not publish nested microformats without a property class name, and instead, when nesting microformats, authors should always specify a property class name (like 'p-org') on the same element as the root class name(s) of the nested microformat(s) (like 'h-card' and/or 'h-org').

'''FOR PARSERS ONLY:'''

Or the nested object could be only marked up with 'h-card'. Source:

<source lang=html4strict>
<div class="h-card">
<a class="p-name u-url"
href="http://blog.lizardwrangler.com/"
>Mitchell Baker</a>
(<a class="h-card"
href="http://mozilla.org/"
>Mozilla Foundation</a>)
</div>
</source>

Parsed JSON:
<source lang=javascript>
{
"items": [{
"type": ["h-card"],
"properties": {
"name": ["Mitchell Baker"],
"url": ["http://blog.lizardwrangler.com/"]
},
"children": [{
"type": ["h-card"],
"properties": {
"name": ["Mozilla Foundation"],
"url": ["http://mozilla.org/"]
}
}]
}]
}
</source>

'''TO DO: Add h-event h-card example and JSON, per real world publishing examples like [http://www.swingtime.co.uk/List/ClSouth.html Swing Time: Classes in Southern England].'''

== authoring ==
=== minimal markup ===
The best way to use microformats-2 is with as little additional markup as possible. This keeps your code cleaner, improves its maintainability, and thus the quality and longevity of your microformats.

One big advantage of microformats-2 over previous microformats (and others) is the ability to add one class name to an existing element to create a structured item.

See the [[microformats-2#simple_microformats_2_examples|simple examples at the top]] for a start, e.g.

Simple hCards work just by adding <code>class="h-card"</code> :
<source lang=html4strict>
<span class="h-card">Frances Berriman</span>

<a class="h-card" href="http://benward.me">Ben Ward</a>

<img class="h-card" alt="Sally Ride"
src="http://upload.wikimedia.org/wikipedia/commons/a/a4/Ride-s.jpg"/>

<a class="h-card" href="http://tantek.com">
<img alt="Tantek Çelik" src="http://ttk.me/logo.jpg"/>
</a>
</source>

* Tip: Inside an open tag, put the <code>class</code> attribute <em>first</em>, then any human text content attributes (e.g. <code>alt</code>), then URL attributes (e.g. <code>href</code> <code>src</code>), and lastly other attributes (e.g. <code>style</code>). Putting the class attribute first ties it closely to the element name/tag itself, makes it more obvious, and thus more likely to be kept up to date.

=== backward compatible ===
If you depend on current microformats [[implementations]], while they're being updated to support [[microformats2]], you can include both existing classic microformats and microformats2 markup.

In short: use both sets of class names simultaneously.

When doing so, use them on the same element, with the microformats-2 class name first, followed immediately by the existing microformats class name.

Here are the microformats-2 hCards from above with current [[hCard]] markup as well, which may require adding a wrapping element (e.g. a <code><span></code>) to separate the root class name element from explicit property class name elements:

<source lang=html4strict>
<span class="h-card vcard">
<span class="p-name fn">Frances Berriman</span>
</span>

<span class="h-card vcard">
<a class="p-name fn u-url url" href="http://benward.me">Ben Ward</a>
</span>

<span class="h-card vcard">
<img class="p-name fn u-photo photo" alt="Sally Ride"
src="http://upload.wikimedia.org/wikipedia/commons/a/a4/Ride-s.jpg"/>
</span>

<span class="h-card vcard">
<a class="u-url url" href="http://tantek.com">
<img class="p-name fn u-photo photo" alt="Tantek Çelik"
src="http://ttk.me/logo.jpg"/>
</a>
</span>
</source>

Tips:
* use the microformats-2 class name first, e.g.
** <code>class="h-card vcard"</code>
** <code>class="u-url url"</code>
* and pair them when using an element for multiple properties, e.g.:
** <code>class="p-name fn u-url url"</code>
** <code>class="p-name fn u-photo photo"</code>
* put microformats classes after classes for CSS (since page authors will likely interact more with their own classes for design than with microformats classes), e.g. as used on individual microformats [[events]] pages:
** <code>class="event-page h-event vevent"</code>

The prefixes (h-, p-, etc.) of microformats2 class names provide easier recognition, and when followed by the similarly named existing class name, they're more easily recognized as related and thus kept together when the markup is maintained over time.

== extensions ==
microformats2 is extensible by means of two separate but syntactically similar extension prefixes for experiments intended to be iterated & evolved and for vendor specific extensions not intended for standardization.

=== experimental extensions ===
There have been times when specific sites have wanted to extend microformats beyond the set of properties in the microformat vocabulary, and currently lack any '''experimental''' way to do so - to try and see if a feature (or even a whole format) is interesting in the real world before bothering to pursue researching and walking it through the microformats process. Thus:

For experimental extensions for the purpose of prototyping to learn more, iterate, towards possibly standardizing, use the <code>-x-</code> prefix before root and property class names.

Specifically:
* '*-x-' + '-' + meaningful name for root and property class names
** where "*" indicates the single-character-prefix as defined above
** where "x" indicates a literal 'x' for an experimental extension

Examples:
* "p-x-prep-time" - a possible experimental property name to be added to [[h-recipe]] upon consideration/documentation of real-world usage/uptake.

See [[microformats2-experimental-properties]] for more examples.

=== <span id="VENDOR_EXTENSIONS">vendor extensions</span> ===
For vendor specific extensions, microformats2 uses a mechanism similar to CSS vendor extensions, using a similar syntax as experimental extensions, except with a vendor prefix instead of a literal 'x'.

* '*-x-' + '-' + meaningful name for root and property class names
** where "*" indicates the single-character-prefix as defined above
** where "x" indicates a vendor prefix (more than one character, e.g. like CSS vendor extension abbreviations, or some stock symbols, avoiding first words/phrases/abbreviations of microformats properties like dt-, numbers allowed after first character)

Examples:
* "h-bigco-one-ring" - a hypothetical "bigco" vendor-specific "one-ring" microformat root class name.
* "p-goog-preptime" - to represent [http://www.google.com/support/webmasters/bin/answer.py?answer=173379 Google's "preptime" property extension] to [[hRecipe]] (aside: "duration" may be another property type to consider separate from "datetime" as it may be subject to different parsing rules.)

See [[vendor-prefixes]] for more examples.

=== extensions background ===
This extensibility mechanism is a composition of the following (at least somewhat) successful extension syntaxes:
* [http://www.w3.org/TR/CSS21/syndata.html#vendor-keywords CSS 2.1 4.1.2.1 Vendor-specific extensions]
* IETF MIME/content-type "x-*" extensions per RFC 2045 Section 6.3. [http://en.wikipedia.org/wiki/Internet_media_type]
* IETF MIME experimental fields (e.g. x-spam-score)
* HTTP header extensions (e.g. x-pingback)
* note also [http://www.mnot.net/blog/2009/02/18/x- some critical thoughts from mnot]

In particular:

Proprietary extensions to formats have typically been shortlived experimental failures with one big recent exception.

Proprietary or experimental CSS3 property implementations have been very successful.

There has been much use of border radius properties and animations/transitions which use CSS properties with vendor-specific prefixes like:

* -moz-border-radius
* -webkit-border-radius

etc.

Note that these are merely string '''prefixes''', not bound to any URL, and thus not namespaces in any practical sense of the word. This is quite an important distinction, as avoiding the need to bind to a URL has made them easier to support and use.

This use of vendor specific CSS properties allowed the larger web design/development/implementor communities to experiment and iterate on new CSS features while the features were being developed and standardized.

The benefits have been two-fold:
* designers have been able to make more attractive sites sooner (at least in some browsers)
* features have been market / real-world tested before being fully standardized, thus resulting in better features

Implementers have used/introduced "x-" prefixes for IETF MIME/content-types for experimental content-types, MIME parameter extensions, and HTTP header extensions, per RFC 2045 Section 6.3, RFC 3798 section 3.3, and [https://secure.wikimedia.org/wikipedia/en/wiki/List_of_HTTP_header_fields#Common_non-standard_headers Wikipedia: HTTP header fields - non-standard headers] (could use RFC reference instead) respectively, like:

* application/x-latex (per [https://secure.wikimedia.org/wikipedia/en/wiki/Internet_media_type#Type_x Wikipedia Internet media type: Type x])
* x-spam-score (in email headers)
* X-Pingback (per [http://en.wikipedia.org/wiki/Pingback Wikipedia:Pingback])

Some standard types started as experimental "x-" types, thus demonstrating this experiment first, standardize later approach has worked for at least some cases:

* image/x-png (standardized as image/png, both per [http://tools.ietf.org/html/rfc2083 RFC2083])

{{DISPLAYTITLE:opening hours brainstorming}}

* [[opening-hours-examples]]
* [[opening-hours-formats]]
* [[opening-hours-brainstorming]]

== brainstorming ==
Brainstorming proposals should only be written up after examples and formats research has been completed per the [[process]].

=== calendar of unnamed events ===
As suggested by jacky in [[irc]], a calendar of unnamed events (using [[h-event]]), perhaps nested in the venue's [[h-card]], maybe sufficient to imply/convey opening hours for those days.

* I think opening hours is worth its own type. `h-x-opening-hours` or some such thing. With a single property that is a nested h-event. [[User:Btrem|Btrem]] ([[User talk:Btrem|talk]]) 02:38, 20 February 2021 (UTC)
* My only hesistation against making a new type is that the 'specifics' are things that can be defined by a machine (when to start, when to end) and everything else is human-specific (and thus a rendering layer). [[User:Jacky|Jacky]] 18:41, 20 Feb 2021 PST

Jacky: /* calendar of unnamed events */ add example of using h-event for open hours

{{DISPLAYTITLE:opening hours brainstorming}}
This is part of an effort per the microformats [[process]] to research, gather examples, and brainstorm for a microformat for marking up the '''opening hours''' for a business or organization.
* [[opening-hours-examples]]
* [[opening-hours-formats]]
* [[opening-hours-brainstorming]]

== brainstorming ==
Brainstorming proposals should only be written up after examples and formats research has been completed per the [[process]].

=== calendar of unnamed events ===
As suggested by jacky in [[irc]], a calendar of unnamed events (using [[h-event]]), perhaps nested in the venue's [[h-card]], maybe sufficient to imply/convey opening hours for those days.

I think opening hours is worth its own type. `h-x-opening-hours` or some such thing. With a single property that is a nested h-event. [[User:Btrem|Btrem]] ([[User talk:Btrem|talk]]) 02:38, 20 February 2021 (UTC)

My only hesistation against making a new type is that the 'specifics' are things that can be defined by a machine (when to start, when to end) and everything else is human-specific (and thus a rendering layer). [[User:Jacky|Jacky]] 18:41, 20 Feb 2021 PST

==== [[User:Jacky|Jacky]]'s Idea for Rendering a Week of Hours ====

Main Page:
<pre>
<aside class="h-card">
We're open <a class="h-event u-url" href="/open-days" rel="calendar" title="Open Hours">Tuesdays to Fridays from 10 AM to 9 PM</a>, closed Sundays, Saturdays and Mondays.
</aside>
</pre>

Event Page:
<pre>
<aside class="h-feed">
<h2 class="p-name>Hours</h2>
<p class="h-event" id="Monday">Closed on <a href="#Monday" class="u-url p-name">Mondays</a>.</p>
<p class="h-event" id="Tuesday"><a href="#Tuesday" class="u-url p-name">Tuesday</a> from <time class="dt-start" datetime="9:00AM">9 AM</time> to <time class="dt-end" datetime="6:00PM">6 PM</time>.</p>
</aside>
</pre>

=== simple class proposal ===
proposed format:

<nowiki><span class="operating-hours">
Tu-Sa 08:00-15:00; Sa 08:00-12:00
</span></nowiki>

see it here: http://www.geodatacheck.com/p/2

Use a semicolon to separate the different days or or time ranges.
Use two letter english day names. Times are local times with leading zero

This is the format as used in openstreetmap.org for a node description with opening hours. Openstreetmap has very rigid semantics, so it makes sense to follow their format.
