To Do

This page is for posting microformats related shared to do items. If you want to use this page for your microformats related to-do items, create a section with your name on it. The reason we are keeping these all on the same page is to make it easier to tell when people are working on similar things, and to make it more obvious when people help out with other people's tasks. In theory this probably won't scale, but let's first see how it does in practice. :) - Tantek

Lazyweb

Just some nice things, feel free to do any of these.

for all microformats

  • quick and easy "how to" pages for each microformat. use is a good overall start.
  • brief summary statements for each microformat that explain why it matters, what does it accomplish for the publisher.
  • write up mailing-list questions and answers in the appropriate faq pages.
  • validators. See the hReview section below as there has been a request for an hReview validator in particular. See Norman Walsh's blog post "Validating microformats" for some valuable analysis and validation pseudo-code (prose description), which are useful steps towards building microformat validators.
  • Create a microformat (based on hCalendar?) for marking up the opening hours of stores and restaurants. Some people seem to believe hCalenders repeating event support isn't good enough for this and needs to be amended first.
  • Add OpenID to Microformats Blog.

hReview

  • hReview support in Ecto (hey Adriaan!), requested by Andy Smith
  • an hReview validator.
  • a semantic, clean css star rating picker (e.g. a UI widget to rate from 1-5 stars)

hCard

hCalendar/hCard/hReview editor

  • onblur in the URL field (e.g. on hCalendar), goes out and tries to retrieve an object of same time (e.g. an hCalendar vevent) from that URL and uses it to autofill the form, same thing if the creator is loaded with that URL prefilled (e.g. due to a ?url=http://example.com/ in the URL that loads the creator).

WordPress patches for microformats

  • submit patches for WordPress code/templates for microformats improvement
  • Wordpress plugin for microformats, specifically hReview and hCalendar

Yahoo Open Source Library Patches

Several of these could very much be improved with a little microformats markup. Do we just make patches and submit them? Contact Nate Koechley at Yahoo (see Tantek for contact info) to follow-up.

Drupal patches for microformats

  • Microformat Module for Drupal A group discussing ways to implement microformats in Drupal. Currently looking to support hAtom, hCard and hCalendar to start with. Contact digitalspaghetti at gmail dot com if you are interested in contributing to the project.

Adding Microformats to Existing Pages

Geotagging on Wikipedia

Somebody familiar with the "geo" microformat might want to add details, and a link to the relevant page on this Wiki, to the Wikipedia page on Geotagging. Andy Mabbett

rel-tagging on Wikipedia

Somebody familiar with the "rel-tag" microformat might want to add details, and a link to the relevant page on this Wiki, to the Wikipedia page on tagging. Andy Mabbett 14:07, 3 Jan 2007 (PST)

Tantek

I'm keeping a few microformats related to-do items here both for my own convenience, and for folks looking to help out with small tasks. If so, just create a new section with your name, and and maybe copy the item there, and put your name next to the item in my list. We'll figure this out as we go along. Thanks, Tantek.

overall priority ordering

  1. Protect the community from threats (wiki damage, mailing list pain or noise), repair damage, add measures to reduce future damage
  2. Help publishers with established microformats: hCard, hCalendar, hReview, xFolk
  3. Help implementers with established microformats
  4. Wiki cleanup/gardening for existing established microformats
  5. Site usability
  6. Iterate on existing established microformats, resolve issues/feedback etc.
  7. Community dynamics, process and principles improvements to help guide new microformats developments
  8. Emerging in-demand microformats: hListing, citation using abovementioned process and principles improvements.
  9. New microformat requests
  10. Other

protect the community

  • Analyze Special:Recentchanges and mailing-lists and:
    • add to mailing-lists policies/guidelines accordingly.
    • privately email violaters kindly asking them to improve their behavior
    • work with admins on next steps for individuals negatively impacting the community
    • recognize noisy/distracting threads on the email list, document responses/answers to such subjects on the appropriate page(s) on the wiki, and reply to those threads with the URLs to the documentation on the wiki. Putting the responses/answers on the wiki helps by hopefully providing preemptive answers to some who might reraise the subjects on the list in the future, and helps the community quickly terminate such threads by using the answers on the wiki.

help publishers

  • (: advocacy - add pages/sites that could use microformats, update them with sample markup, find contacts for those pages to get them updated, and send requests to update their sites with microformats including sample markup.

*-authoring microformats wiki pages

  • Add some tips to hcard-authoring
    • a tutorial on creating an hCard for your site
    • specific instructions for common blogging platforms
    • instructions for more properties (match at least the set that is in the hCard creator)
  • Create hreview-authoring - a tutorial on how to blog reviews so that they'll be aggregated.

help with microformat examples in the wild

Go over all "common" pages (both logged out and logged in states) of the following sites which have some microformats already, and verify each page is as microformatted as it can be with high fidelity hCalendar and hCard etc. Document full support of each implementation's microformats on the implementations page (perhaps create a separate page for each implementation, e.g. flickr, upcoming, eventful etc.) Document any exceptions as needed. In no particular order:

  • Flickr.com (3.5m hCards)
  • Upcoming.org (100k hCalendar events, 100k hCard venues)
    • home page
  • Eventful.com (100k hCalendar events, 100k hCard venues)
  • Yahoo! Tech (300k products with hReviews)
  • JudysBook.com (???k hReviews)
  • ... lots more, get from "Implementations" and "Examples in the Wild" sections of specs.

help implementers

  • wordpress improvements
    • WP admin for new profiles
      • should simply read blog URL
      • look for hcards and parse them
  • XFN Creator localizations
  • Conference Schedule Creator
    • We need to ASAP build a simple conference schedule creator (and editor?) that builds upon the hCalendar creator. We should make it *trivial* for conference organizers to build/edit/publish an hCalendar schedule for their conference, including auto-generated "Subscribe..." link which produces the proper "webcal:..." link with X2V. Note: see the "axis" and "header" attributes in HTML4, specifically in the section on Tables. (Done. Feedback wanted. Conference Schedule Creator)

wiki cleanup

for all microformat specs

update specification section organization

In particular, the introduction/boilerplate/headers. hResume has an experimental abbreviated intro/headers section, and links to more details further below, based on some ideas that Ryan King and I had for improving the readability of the microformats specifications. hReview has some similar improvements, but different. We need to:

  1. Figure out if the new intro/headers structure in hResume and/or hReview is an improvement, and if it could be better. Perhaps figure out the requirements for an intro/header section
    • Shorter tends to be better
    • Must be comprehensive enough to "print and read"
    • Must detail authorship/editorship
    • Must detail copyright/patent statements
  2. Write up a template - make it self-documenting per the requirements
  3. Update existing specifications with the new intro/headers structure.
    1. hCard
    2. hCalendar
    3. hReview

reorganizing Implementations sections

  • sort implementations by authoring/creating/publishing, browsing/viewing, converting/importing, indexing/searching.

Hmmm... I like: Authoring, Browsing, Converting, Indexing, Libraries (for developers), and Potential (for open source projects we want to add support to). Anybody have alternative suggestions for this vocabulary? I don't have a particularly strong preference so I'm going to go with these four until I find examples that don't fit, or someone suggests something better.

See: hCalendar Implementations for a first attempt at this. Assuming folks like that, we can go ahead with categorizing the implementations sections of other microformats specifications.

reorg Examples in the Wild sections

  • include more *key* details per example, e.g. precise or estimates of counts for services
  • collate/sort examples in the wild by
    • hosting services - where users/people actively contribute to the growth (e.g. Flickr profile hCards)
    • publishing services - where lots of data is published from some datasource/database (e.g. Yahoo! Local)
    • companies/groups/organizations member pages (and their own) - pages for a group's site where they list members or employees (e.g. Technorati staff page)
    • individiual companies/organizations contact info pages
    • individual people's contact info pages
  • of course at some point this won't scale, but that will be a very good problem to have, and by then I'm sure we'll have services to point to that provide queries and search results for all this data.

site usability

  • figure out how to get wordpress to autopost blog posts to the microformats-announce list
    • ideally use the from address of the author of the blog post
    • maybe photomatt knows how to do this.

iterate on current microformats

hCard

  • hcard-examples
  • hcard-examples-in-wild
    • Group examples in the wild according to:
      • Individuals - one card per person, perhaps sort alphabetically
      • Organizations - one card per organization, alphabetical again
      • Institutions (which list more than one person), with a count estimating the # of hCards, e.g. 40k for Avon. Also indicate complexity of information supplied, eg. just name+number vs. complete details
      • Online Profiles (which host profiles for more than one person) with a count estimating the # of hCards, e.g. 3.5m for Flickr.com
      • Online Venues (which provide listings for businesses or organizations) with a count estimating the # of venues, e.g. ~10k for Upcoming.org
      • Speakers Listings (lists of speakers on conference sites) with a count estimating the # of speakers, e.g. ~300 for SXSW 2006.
    • help dglazkov markup: http://glazkov.com/blog/archive/2003/12/17/147.aspx
  • hcard-brainstorming

hCalendar

hReview

  • Write hReview 0.3 XMDP profile, and reconcile with hcalendar-profile and hcard-profile. Makes sense to have a combined profile of all three for hReview, since hReview normatively depends on hCard and hCalendar.

summary Examples in the Wild page

  • need to create a summary / overall examples-in-the-wild page
    • parallel the summary/overall implementations page.
    • use newly reoganized content from the above "reoganizing Examples in the Wild" task

parsing

introduction / community

  • microformats-discuss
    • introductory email template for new subscribers needs to direct people to process and how-to-play
  • Need to add more to the naming-principles, to cover in particular:
    • avoid using the same name to mean two things
    • avoid using two names to mean the same thing
    • seek to keep the microformats vocabulary minimal, memorable, and usable.
  • update and add details/simplifications to process given the past several months of experience. in particular:
    • clarify requirement (MUST rather than SHOULD) of *-examples, *-formats, before any *-brainstorming.
    • Add details of encouragement to experiment with simple semantic class names from *-brainstorming proposals to gain real world experience with real world content.
    • note SHOULD prerequisite of use of all relevant microformats on real world web pages, along with documenting such use in respective "Examples in the Wild" sections, before proposing any new microformats.

principles and process

Create the following pages and document/fill them with content from other pages, email lists, and presentations.

profiles

  • update XMDP with new required features:
    • ability for one profile to include/import another (rel="import" ?)
    • ability to reference an XMDP via rel="profile" (similar to XHTML2 rel value by same name)
    • ability/suggestion to reference an XMDP using <a href> in addition to <link>

community mark

document issue resolutions

  • Prefixing has already been considered and rejected for microformats in general. Note naming-conventions, limited vocabulary, and exceptions made for hAtom and how we went about doing so.

hAtom2Atom

Some ideas for features which could be implemented :

(If you are interested in one of this features, add "+1 Your Name")

  • Join all hfeed's inside a page (or a fragment thereof) into one feed using atom:source semantics.
  • Extraction of atom:content, atom:summary and atom:title:
    • atom:content and atom:summary as HTML
    • atom:content and atom:summary as plain-text
    • atom:title as XHTML
    • atom:title as HTML
  • Support for other XSLT engines:
    • MSXML
    • .Net System.Xml
    • Sablotron
    • Oracle XSLT
    • XT
    • hAtom2Atom written using XSL 2.0?
      • Do you think this would be useful? I have created a barebones version, doesn't yet take in all the parsing rules yet, but I'd be happy to share. Moving to XSL 2.0 does make things a bit cleaner and more efficient. - Matt Dertinger.
  • Support for other output formats: (hAtom2xyz.xsl)
    • RSS 2.0 (meanwhile use hAtom2Atom.xsl and atom2rss.xsl) -- +1 Matt Dertinger
    • RSS 1.0 (meanwhile use hAtom2Atom.xsl and atom2rss.xslt) -- +1 Matt Dertinger
    • AtomOWL (meanwhile use hAtom2Atom.xsl and atom2rdfxml.xsl)-- +1 Matt Dertinger
    • JSON?
      • Does it make sense to consider a canonical representation of microformats (either case by case, or in general) in JSON? E.g. so that a JSON API that returned contact information could return an hCard-equivalent chunk of JSON. - Tantek.

Wiki-Thon Proposal

Set aside several hours (probably a Friday night US PST) for focused work on the Wiki, including both physical (e.g., a room in the Bay Area) and virtual (IRC/iChat) participants.

Goals

  1. Improve understanding of what needs to be done for Wiki
    • IMHO - this should be done here, in to-do incrementally. -Tantek
  2. Tackle larger projects (~1-2 hours) than people usually have time for
    • I'd like to see these projects *documented* first on to-do before we spend 1-2 hours of a bunch of folk's collective time to go through them. -Tantek
  3. Motivate community to have fun with otherwise tedious "housecleaning" chores

Agenda (Wishlist)

In parallel:

  • Coalesce/prioritize existing To-Do items (above)
  • Review/revise desired pathways for:
    • New users learning about microformats
      • e.g., intro, about, explore, tutorials, etc.
      • cf. Rails front page
        • Get Excited (Why, background, motivation)
        • Get Started (What, downloads, getting started)
        • Get Better (How, tutorials, )
        • Get Involved (Who)
    • Microformat lifecycle
  • Review existing specs for completeness and consistency
  • Identify areas of 'bitrot' or 'hole-filling'
  • Do it!

Vocabulary

A lot of knowledge work is about maintaining sets of vocabulary. Now that the vocabulary is emerging, it may be time start making sure everyone is "on the same page," especially since some of the language is highly symbolic. Terms:

  • "boil the ocean" A huge task. "A phrase used in the industry to describe an attempt at something that is way too ambitious. For example, "They're trying to get their site launched by COMDEX. They could easier boil the ocean." from <http://www.netlingo.com/right.cfm?term=boil%20the%20ocean>
  • microformats: more than one microformat
  • microformat: see my definition on http://microformats.org/wiki/what-are-microformats#BenWest
  • data fidelity: the extent to which a data format might be considered lossy. eg HTML is often seen as a lossy format because the information parsed out of a resource may not fully match the information orginally encoded. Non-lossy formats have a very high data fidelity, while lossy formats have low data fidelity. Microformats seek to increase data fidelity of html.
  • market: the locus of economic forces
See glossary. Andy Mabbett 13:57, 7 Dec 2006 (PST)

Creators

_Concession_: my plans involve reuse of code, which would involve non-compatible changes with the current inline model. This is a nice feature, so maybe I should be branching instead.

  • Start hatom creator. http://dichotomize.com/uf/hatom/creator.html
  • Code Reuse. These creators are downright handy, and I’ve reimplemented the vcard one on my own site. Instead, let’s make these widgetized. Let’s decide on a more or less canonical html structure and create some javascript that will create the desired microformat. Something as easy to use as new Microformat.hCard($('mycontainer')); would be awesome. Right now, if someone makes an improvement to the hCard creator, the other creators don’t get the benefit. Spec this out!
  • About Section. Is there an official creator page? If so, let’s point to that. The about paragraph is getting longer and longer with phrases like “which is based on…” repeated over and over.
  • Default all dates to “right now”. Provide an easy to use calendar type widget to change dates.
  • hAtom creator: Add multiple. It’d be nice to add an arbitrary number of entries.
  • hAtom creator: Optional feed enclosure. Check box to wrap the entry/entries in an hfeed.
  • Edit URI: Allow someone to enter a URI and edit whatever microformat is found on the page.
  • Optionals. If the format requires, say, a vcard, the creator can defer to an external URI or can trust the user to fill it in later.
  • Common stylesheet. I suppose this goes with the reuseable code idea… we have many great coders, we should be reusing eachothers’ work.
  • Use Amazon's ECS to pull in information about products when there is an ASIN in the item URI.

Information Architecture

Help Welcomed! Please leave your name Add complaints to wiki-feedback! Helping to make the wiki easier to use. I'd like to see the main page more towards a format like http://simile.mit.edu/solvent/ with the big questions right out front:

  • What Is This?
  • What can I do here?
  • Is there a demo?
  • Where can I learn more?

I'd like to change the front page to this kind of design.

Support Pages

There are several categories of things in the wiki. Can we enumerate them?

  • About the Community
    • Where to find information.
    • Who are the stake holders?
    • FAQs
  • Web/Architectural Philosophy
    • Community Principles
    • Why are we doing this?

    • advocating use
    • collaborating/reusing HTML
    • debugging HTML: use pastebin, separate out the relevant bits.
    • getting help from the community
    • applying Microformats.

Can others agree and or refine this list? Should I take it to the -discuss list? How do we create consensus on how the wiki should be organized in order to make it more usable? And how can we turn that consensus into actionable changes?

The wiki should also capture wisdom that stems from discussions that don't produce microformats. For example, Chris Messina suggests a "Best Of" page suitable for capturing this kind of wisdom. I think we can think of a given microformat as being at a place in a spectrum that ranges from "not yet thought of", to "interesting but needs work," or even "rejected", and of course including all the stages familiar to the microformats processes (eg examples, brainstorming, etc...). If there were such a page would it:

  • Belong to a microformat? (eg hcard-bestof)
  • or to the global namespace? (eg /wiki/wisdom/foobar-format)

(I think Chris Messina suggests that it belongs to a given microformat, but then how do we collect wisdom from non-microformats?)

Considering that the wiki page named with the microformat (i.e. /wiki/hcard) is the one that people will mostly likely look to first for learning about a particular format, I'd think it'd make more sense and create a more welcoming feel to convert these pages to an intro page introducing the format for the beginner and linking to resources like tutorials and creators. Spec pages would then be relocated to wiki/*-spec -- Cgriego 13:25, 16 Oct 2006 (PDT)

Mike Schinkel's Comments

My suggestion on the list was for us to use a convention that the entry page (i.e. http://microformats.org/wiki/hcard) would be an index into a list of (psuedo) standardized sub pages so that it would be very people to find what is important to them. For example, is a list of potential sub pages:

  • Microformat
    • Specification
    • Tutorial
    • Examples
    • Use cases
    • Reference
    • Discussion
    • Brainstorming (might be combined w/Discussion)
    • Implementations
    • Related Pages
    • Further Reading
    • All (Uses Mediawiki's "includes" to create a page including all sub pages; very useful for printing & reading offline)

These pages would be located respectively at

Please note I am suggesting an architecture not a specific list of sub pages. The list of sub pages should be defined by both reviewing existing information during site reorganization, and then via discussion on the list in an attempt to discover and extract which sub pages are needed for most/all microformats.

NOTE: This differs from above in that the spec if not viewed as a top level structure but instead the microformat itself and the spec would be under the microformat. In this context "microformat" is a more abstract concept and "spec" is a more concrete thing. Another way to think about it would be that each microformat would have it's own mini home page and then things like "spec" are the pages listed on its home page.
