| | HOW THING OUT |
| ==== No defined parsing rule for <code>updated</code> timestamps in <code>ins</code>elements ====
| | HOW MAKE THING OUT |
| * {{OpenIssue}} 2010-01-20 raised by [[User:BenWard|BenWard]]
| | HOW THING BE OUT |
| *# hAtom includes the <code>updated</code> property for the last modification/revision date of an entry. HTML already has an <code>ins</code> element for marking up inserted changes to text, and that element has a <code>datetime</code> attribute, to document the date and time of the change. Currently, hAtom and microformats have no model for parsing the data from that <code>datetime</code> attribute, but the document semantics suggest it would be an appropriate source for the <code>updated</code> property. Example: <http://blog.benward.me/post/250674456>
| | HOW MAKE THING BE OUT |
| *#* Proposed resolution. Document a parsing rule for the <code>ins</code> element, stating that for an <code>ins</code> (or <code>del</code>) element with class of <code>updated</code>, the value of the <code>datetime</code> attribute should be used as the value.
| | HOW ANYTHING OUT |
| *#** +1 This sounds like a good idea and something worthy of being incorporated into [[hcard-parsing#more_semantic_exceptions]] (which is where the core of generic microformat parsing is currently documented) for special handling for all datetime properties.

| | HOW ANYTHING BE OUT |
| *#* Proposed extended resolution: As well as the above explicit parsing rule, an implication parsing rule stating that where <code>update</code> is not explicitly marked up, the parser may aggregate all <code>ins</code> and <code>del</code> elements in the <code>hentry</code>, and use the most recent <code>datetime</code> attribute content as the <code>updated</code> value.
| | HOW MAKE ANYTHING BE OUT |
| *#** +1 Brilliant. Indeed right now 'updated', if missing, is implied from the 'published' property. Suggested change to that rule (incorporating your proposal) : if 'updated' is missing, use the latest in time value of: the 'published' property value, and the 'datetime' attributes of all ins and del elements inside the hentry.

| ==== too many required hentry properties ====
| | HOW MAKE ANYTHING BE THROUGH |
| * {{OpenIssue}} 2009-05-26 raised by [[User:Tantek|Tantek]]
| | HOW EVERYTHING THROUGH |
| *# hAtom 0.1 requires numerous properties for an hentry (often based directly on required elements from the Atom standard). Given the broad variety of situations that hAtom is used in content, many (or even most) of these properties are not already specified in such content, and thus it is poor methodology to require them because there is a good chance (experience has shown) either (a) the content author will ignore the requirement, or (b) will make something up to satisfy the requirement. A few similar/overlapping/sub-issues are noted below (e.g. [[#Author|author is required]], and not always available).
| | HOW MAKE EVERYTHING THROUGH |
| *#* Proposed resolution. Make nearly all hentry properties "optional" in hAtom 0.2. Consider keeping at most only one required property, perhaps "updated" - that is, if there is no date of update/publication in the content you are trying to mark up, then perhaps it doesn't make sense to mark up that content with hAtom, since hAtom is for episodic, time-based/stamped content.
| | HOW EVERYTHING BE THROUGH |
| *#** consider pattern abstraction: all microformats should minimize "required" properties for the same reason, and perhaps ''only'' require at most a single property which is indicative of what that microformat is for, that is, if the author does not publish that one required property, then perhaps they should not be using the microformat that requires that one property.
| | HOW MAKE EVERYTHING BE THROUGH |
| *#* I have the same problem. I'm collecting various feeds to analyse them. The sources are often RSS 0.9, but I want to put the results into an Atom feed. --[[User:Simon Brodtmann|Simon Brodtmann]] 00:51, 1 July 2009 (UTC)

| **** [[User:DavidJanes]] what should it be then, if physically representing it is optional? Since Atom makes this a SHOULD and not a MUST (I'm not shouting, just following RFC convention), and we're assuming there's a good reason for the entry-title not to be present in the first place, why not an empty string?
| |
| ***** [[User:WebOrganics|Martin McEvoy]] entry:title is a required attribute of atom at both feed and entry level, in both instances it says "Contains a human readable title" (a requirement) an empty string is not anything human readable (personal oppinion), maybe hAtom 0.2 should only recommend that the value of entry-title "should" not be an empty string.

| *** the value should be NULL.
| |
| **** +1 [[User:Bmearns|Bmearns]]: Whatever that may mean to the specific handler. A blank string implies that a handler which generates HTML content, for instance, should generate <code><H1></H1></code>, as opposed to just omitting the title all together.

| |
| * {{OpenIssue}} 2008-09-10 raised by [[User:Tantek|Tantek]]
| |
| *# hAtom 0.1 uses [[rel-bookmark]] for permalinks. Permalinks may not always be hyperlinks or hyperlinkable. Thus I propose we re-use the <code>url</code> property (from [[hCard]], [[hCalendar]], [[hReview]], etc.) as a sub-property of the <code>hentry</code> property/container/root.

The address element means the ''contact'' for the page or major portion thereof (see [[hcard-faq#Should_I_use_ADDRESS_for_hCards|hCard FAQ: Should I use ADDRESS for hCards]]), which ''may'' also be the ''author'' but is not necessarily. See [[hcards-and-pages]] for more details on this semantic distinction.

| ==== Relationship of rel-bookmark to url+uid ====
| |
| The concept of permalink is available in hCard and hCalendar as the classes url and uid. This combination matches the permalink semantics by indicating that the url should be derefenced to find a more dynamic or up-to-date version of the content, and that that url is a stable unique id that can be used to identify the content.
| |
| | |
| hAtom 0.1 uses rel-bookmark for the permalink concept. The current state of [[uid-brainstorming]] indicates that the [[hCard]] and [[hCalendar]] permalink concept is likely to be used in subsequent microformats. It may be important to reconcile hAtom with that trajectory. Possible reconcilliations include:
| |
| | |
| 1) To leave things as they are. The two permalink concepts are to be kept separate.
| |
| | |
| 2) Treat the two concepts as equivalent. Allow both in hAtom, and consider allowing both in other formats. eg <a rel="bookmark" href="http://example.com/"> would fill out uid and url values if they are not supplied explicitly.
| |
| | |
| 3) Choose one over the other for hAtom and perhaps for future microformats also. "url uid" allows for some greater freedom (uid can be pointed at a non-url uid), but it is unclear at this stage whether that freedom is warranted or advisable to permit.

| It is suggested the Feed permalink should be used as the feed ID, however a piece by Mark Pilgrim (http://diveintomark.org/archives/2004/05/28/howto-atom-id) makes arguments against using permalinks and in favour of Tag URIs.

| |
| ** 2006-04-03 [[User:ChrisCasciano|ChrisCasciano]] - I'm not sure that having a rel-boomkark-able link element at the feed level / to designate a feed in an html page separate for the other content is anything close to normal usage on the web, so I'd be very hesitant on suggesting this element "SHOULD" exist. I'm also curious when this element would link to anything but the current page (or some element on the current page) for this to be useful in the context of the HTML doc. I think taking the "id" on the feed is a more workable solution in most cases.
| |
| ** 2006-04-03 [[User:RobertBachmann|Robert Bachmann]]: I've replaced "SHOULD" with "MAY".
| |
| ** 2006-04-24 [[User:RobertBachmann|Robert Bachmann]]: Maybe we could simplify my proposal to:
| |
| *** "''Use the URI of the page; if the Feed has an "id" attribute, add that as a fragment to the page URI''"

| ** [[User:Singpolyma|singpolyma]] 00:05, 13 Apr 2006 (PDT) : since the link is going to be pointing to the home page for the item wouldn't [[rel-home]] make more sense? That's what I'm using in the XOXO Blog Format and my reasoning was that if hAtom ever defined this rel=home made the most sense for what you would add, because the feed's link is not to a part of the site by to the home of the site.

| |
| ** 2007-06-20 [[User:MikeKaply]] The "youngest" thing is a really bad idea. If a page has 100 hAtom entries, a parser would have to go through all 100 looking for a low date. That's crazy.
| |
| *** 2008-03-20 [[User:TobyInk]] Not crazy at all. I've just implemented an hAtom to Atom converter and I do precisely this. Most (useful) hAtom parsers will "go through all 100 entries" anyway, won't they? So why not look for the youngest updated date as part of that loop. The only slight annoyance is that in RFC 4287, the <atom:updated> element must occur before the first <atom:entry> element -- this is easily solved by inserting a placeholder <atom:updated> element, looping through the entries and then going back and filling in the date. This is really, really, '''not''' a difficult thing to implement.

| |
| ** I'm proposing the following rules for entry author:
| |
| **# an Entry Author element is represented by class name <code>author</code>
| |
| **# an Entry Author element represents the concept of an Atom author
| |
| **# an Entry Author element MUST be encoded in an [[hcard|hCard]]
| |
| **# an Entry Author element SHOULD be encoded in an <code><address></code> element
| |
| **#<del> If a Feed has no Feed author each Entry MUST have at least one Entry Author element</del>
| |
| **# <ins>If an Entry is enclosed by a Feed and this Feed has no Feed author, each Entry MUST have at least one Entry Author element. If an Entry is not enclosed by a Feed and has no Entry Author:
| |
| **#* find the [[algorithm-nearest-in-parent|Nearest In Parent]] <code><address></code> element(s) with class name <code>author</code> and that is/are a valid [[hcard|hCard]]
| |
| **#* otherwise the Entry is invalid hAtom</ins>
| |
| **# an Entry MAY have more than one Entry Author elements
| |
| ** [[User:Singpolyma|singpolyma]] 00:11, 13 Apr 2006 (PDT) : feed should not be invalid hAtom if feed-level has no author -- it should be invalid if feed-level has no author AND one or more entries have no author. Also, one or more entries may be missing an author IF feed-level has an author.
| |
| ** 2006-04-17 [[User:RobertBachmann|Robert Bachmann]]: I replaced "the Feed is invalid hAtom" with "there is no Feed Author"

| |
| * {{OpenIssue}}2006-04-01 raised by [[User:RobertBachmann|Robert Bachmann]]
| |
| ** atom:<i>id</i> is required for atom:entry. Thus it should be available in hAtom to. The Entry permalink should be used as the entry id.
| |
| ** --[[User:Federico|Federico]] 19:52, 25 Apr 2006 (PDT): I would add "Only if the id attribute is not defined for the element that contains the entry". The id attribute can be a tag uri. If you use always use the Entry permalink as the entry id and the Atom feed uses tag uris, you would end with two different ids for the same entry.
| |
| ** 2006-12-31 response by [[User:ComputerKid|Emanla Eraton]] No, it shouldn't be a permalink. It should be a "tag:" id for entries.
| |
| ** 2007-06-06 [[RyanKing]] - the syntax of tag URIs and html id attributes are incompatible. HTML disallows forward-slash (/) in ids [http://www.w3.org/TR/html401/types.html#type-name], while tag URIs require them [http://www.faqs.org/rfcs/rfc4151.html].

| ==== Author ====
| |
| ===== author as an hcard is too much to require =====
| |
| The following 3 items were extracted from the conversation starting on irc with [http://rbach.priv.at/Microformats-IRC/2006-03-24#T152248 logs available starting around here]
| |
| | |
| * [[User:Fil|Fil]] If, for example, you are programming an "aggregator" of news syndicated from many sources like in [http://sedna.spip.org/sedna/ Sedna], chances are that you don't control what "authors" look like; they can be nicely microformated (if coming from an mf-enabled system), but most probably they will be internally represented by a string that contains, in some random order, a name, and/or an email, and so on. If you want to pass on this information in an hAtom feed, you can't possibly reformat it to an hCard. But you still want to pass it on in a <div class="author"> element.
| |
| ** [[Tantek]] I don't believe the "can't possibly" statement. Please provide a URL to a concrete example that you think you can't possibly reformat into an hCard so we can all take a look.
| |
| ** [[User:ChrisCasciano|ChrisCasciano]] details of Fil's extraction [http://rbach.priv.at/Microformats-IRC/2006-03-24#T153453 in irc logs] including sting data passed to his app in the form of "Béatrice XXXXXXX beatrice.xxxxxx@@zzzzzzzzz.com"
| |
| ** [[User:Fil|Fil]] the example url was given up there (Sedna); note that the author information comes from syndication links; nobody is going to edit them to outline what is the name, what is the email and so on, as everything is flowing through automatically... so here the "author" data is dirty, and will not be cleaned into an hCard. We can force it to be in an hCard but it will be meaningless if the source (original data) wasn't built on an mf-enabled software.
| |
| | |
| * [[pnhChris]] i don't disagree.. the field often comes from places too dumb to follow these rules well; even cases like wordpress that allow users to present their name 1 of 6 or 8 difference ways (from username to LF, FN) .. its not just writing a template to output as hatom at that point... you have to go further upstream where the string to be displayed is chosen .. I also think its pointless to have 10 vcards on the same page whose only data is a generic name like "Chris"
| |
| ** [[Tantek]] 10 vcards that are the same is pointless yes, but identifying who the author of 10 posts are is not pointless - that's the difference.
| |
| ** [[User:ChrisCasciano|ChrisCasciano]] Agreed, but I still have concerns that "author" in hAtom does not always make for good hCards, though the situations where it does is optimal. My comments in the conversation were old comments I've made before over concerns and hardships or the lack of desire to make crappy data more portable, in neither of these cases do I think my two comments alone provide reasons to make change from the hAtom 0.1 spec
| |
| ***[[User:Phae|Frances]] - Just thought I'd mention a scenario I have where the author of an entry does make a pretty useless vCard - the author in each case is an entire team ("creative team", "technical department") etc., rather than a specific, identifiable, person. Some use may be regained when URL to specific team/information is included, in this circumstance.
| |
| ****[[User:TobyInk]] - A vCard (thus an hCard) does not have to represent a person -- it could represent an organisation, or a department or team.
| |
| * [[User:Fil|Fil]] for the moment, to comply losely with hAtom 0.1, I will use <code><nowiki><span class="author"><span class="vcard"><span class="fn">My Name</span></span></span></nowiki></code> ; but it's not good
| |
| ** [[Tantek]] You can actually simplify that (one fewer span) with: <code><nowiki><span class="author vcard"><span class="fn">My Name</span></span></nowiki></code>
| |
| | |
| * require author as [[hCard]] (i.e. no change from 0.1)

| ==== Entry <i>source</i> (atom:<i>source</i>) ====
| |
| * raised by [[User:Kevin Marks|Kevin Marks]]
| |
| ** When defining hAtom 0.1, atom:source was omitted. We should consider adding this back in as a useful element for providing citations of composite feeds.
| |
| *** 2009-07-20 [[User:DavidJanes]] {{ToDo}} we need an example of how this would look in the real world
