Brainstorming for a Comment Microformat

This is a brainstorm for comment microformat. Examples of a comment can be found here comment-examples

Problem

Shortform: How do you track blog comments you've made?

Longform: How do track the comments you have made on blogs, comments made on blogs your interested in and comments other people have made on your own blog?

How can you do this in a pragmatic way, ingested into some kind of data store, searched or aggregated?

Contributors

Discovered Elements

Based on the analysis of 25 real world examples of a comment, the results can be found at the Comment Analysis section

The following properties occur most regularly across all examples (84% or more)

  • comment 100%
  • author 96%
  • published 96%
  • author-url 84%


Other achievable elements

  • comment-link (permalink) 60%

Schema I

Proposal

  • url (author-url) 84%
  • bookmark (comment-link) 60%
    • By adding "bookmark" the author is indicating that the page http://someblog/post#comment-001 is a link to a key entry point within an extended document.

Example

<div class="comment hentry" id="comment-7">
	<p><span class="entry-title">
      <cite class="author vcard">
        <a class="url fn" href="http://notizblog.org" rel="contact external" title="Link to Matthias Pfefferle">Matthias Pfefferle</a>
      </cite> said
    </span> 
    <span class="comment-date">about: 
        <abbr class="updated" title="2008-09-02T01:20:32+01:00">85 days ago</abbr>
    </span></p>
	<div class="entry-content">
      <q cite="http://notizblog.org">Awesome! It works perfect for me. 
      Do you know if its possible to use the firefox microformats api with ubiquity? 
      And by the way... nice webslices implementation on your blog.</q>
  </div>
  <p><a rel="bookmark" href="http://weborganics.co.uk/articles/show/ubiquity-the-best-thing-since-web2-0#comment-7" title="Permalink to this comment">Permalink</a></p>
</div>

Working Examples

  • Comments marked up using hAtom 0.1 example (note: rel="in-reply-to" usage in comments)
    • hAtom to Atom transformation example

Parser Notes

  • If the entry-title element is not used, the atom:title element SHOULD use the author value of the hentry presented in a contextual way, for example by prefixing the author value with "by" or appending it with "said" or "says".
  • The entry-title element SHOULD provide textual content and not be an empty string.

Summary

  • This proposal means that on the whole nothing much is needed for a comment microformat, a comment can re-use terms outlined in the hAtom Microformat

References

Design Notes

Schema II

Proposal

  • reuse hAtom 0.1
  • if Entry "B" is in an Entry Comments element of Entry "A", then Entry "B" is a comment on Entry "A"
  • an Entry Comments element is identified by using both class names "hfeed comments"
<div class="hentry">
   <h3 class="entry-title">The blog post title</h3>
   <div class="entry-content">The blog post text</div>
   (etc)
   <div class="hfeed comments">
       <div class="hentry" id="p0001">
          <div class="entry-content">Comment #1</div>
          (etc)
       </div>
       <div class="hentry" id="p0002">
          <div class="entry-content">Comment #2</div>
          (etc)
       </div>
   </div>
</div>

Details

Specific Example from the Wild

hAtom Comments changes are marked IN UPPER CASE LETTERS FOR VISIBILITY. Assume them to be the normal case in otherwise

(section to be completed)

Feedback

If we can indicate that the hAtom entries are also comments, we could add an indicator beside hAtom.

<div class="hfeed hcomment">

hAtom pattern goes here.

</div>

Alternatively, we could add hcomment with hentry to indicate that the following hentry can be treated also as a comment.

<div class="hentry hcomment">

hEntry pattern goes here.

</div>

  • If an hfeed is embedded in an hEntry, that could be enough context to show "these items are replies to the one they're embedded in" singpolyma 12:20, 25 Sep 2008 (PDT)


hAtom and in-reply-to

A user comment (e.g., in blogs, wikis, forms) can be marked as an hAtom since it has a similar content pattern. A way to differentiate an hEntry (e.g., a blog post) from another hEntry (e.g., a user comment) can be done reusing in-reply-to from Atom Threading Extensions. It provides a mechanism to indicate that an entry is a response to another resource. rel="in-reply-to" can indicate that the current hEntry is a reply to another hEntry and has a reference point @href:

<a rel="in-reply-to" href="#comment_20080902144745">Parent</a>

hEntries that use rel="in-reply-to" can be considered as a comment entry in response to a parent entry in the threaded conversation (e.g., in blogs, wikis, forms).

hEntries that are chronologically listed can all use rel="in-reply-to" and refer to the root hEntry (e.g., blog post, form post)

By reusing in-reply-to, we can solve the microformats representation for user comments [2], [3], [4].

Example comment using in-reply-to: http://www.csarven.ca/my-responses-are-in-white

Idea Consolidation

This is a list of all the various "micro-ideas" that have been discussed on the mailing list in the Wiki, to capture everyone's thoughts and preferences.

  • "examples covered" indicates the percentage of examples that can be marked up without presentation changes
  • Add your comments, objections and votes (-1, 0, +1) as a sublist in "comments" with your wikiname.

use hAtom Entry for a comment

mark the comment permalink with rel="reply"

  • notes:
    • By adding "rel-reply" the author is indicating that the resource indicated by the href is a "reply" to the current document.
  • test cases covered:
    • 60%
  • comments and votes:
    • -0.5 David Janes I have several objections: this seems to be a proper subset of what could be covered by marking a comment hEntry with class="comment", and it seems to being opening up a general "reply/threading" microformat that should be completely and independently analyzed. I have doubt too about how well this will work if the document that's being replied to is specified with hashed URL.
      • Agreed, this needs separate analysis with more use cases Martin McEvoy

mark the comment permalink with rel="in-reply-to"

  • notes:
  • test cases covered:
  • comments and votes:
    • Who proposed this? Sounds like an an abuse of the meaning of rel. -1 from me. TobyInk

add an independent rel="in-reply-to" link

  • notes:
  • test cases covered:
  • comments and votes:
    • As long as it's optional (i.e. not the only way to mark that an hentry is a reply to something), my vote is +1. TobyInk
    • David Janes -1. This seems be inventing something that for the most part is already covered, i.e. is entirely an orthogonal solution. I do not deny this could be of great utility as part of a general threading microformat, but that would have to be independently analyzed.
    • Sarven Capadisli +1 for optional because it has potential to handle various types of commenting where an hentry is a response to another hentry (anywhere):
      • chronological comments
      • threaded comments
      • a blog entry as a reaction to another blog entry
      • microblogging replies

add class="comment" to the comment Entry

  • notes:
    • All the examples studied were the concept of a comment
  • test cases covered:
    • 95% (note the usual DL/DT issues in some Blogger templates)
  • comments and votes:
    • +1 Martin McEvoy
    • 0 David Janes although it covers 100% of the examples, hAtom does have the concept of a cluster of related Entries, and thus I feel it would be better modeled that way.

add hAtom Entry Feed around all comments

  • notes:
  • test cases covered:
  • comments and votes:
    • +1 TobyInk
    • -1 un-necessary just use class="comments" Martin McEvoy
    • 0 unnecessary where there is an indicator for each comment entry if they are chronologically listed as a response to the main post. Perhaps for threaded comments, however, in that case, class="replies" or class="comments" may be more suitable. Sarven Capadisli

add class="comments" (or similar) to a element around all comments

  • notes:
  • test cases covered: 10)%
  • comments and votes:
    • +1, but would prefer class="replies" because of analogy with Atom. Better to reuse an existing vocabulary than pull terms out of a hat. TobyInk
    • +1 David Janes. I'm thinking of this as Entry Replies, which would be physically represented as whatever. Using Entry Replies around all comments would reflect the fact that in 100% of the examples comments come in bunches.
    • +1 There is no reason why not Martin McEvoy
    • +1 Sarven Capadisli. I also prefer class="replies" as it is consistent with the vocabulary in Atom Threaded Extensions.

use XOXO to mark up comments

  • notes:
  • test cases covered:
  • comments and votes:

Twitter is a comments system

  • notes:
  • comments and votes:
    • Indeedy. TobyInk
    • -1 David Janes. Twitter has nothing in common with the other comments system listed. In particular, all replies on Twitter are first class "posts" on your own twitter stream, are done in your own user context, and may not even be replies as they may be conversation initiations.
    • +1 Sarven Capadisli. Microblogging notices that only lead with the "@" character (see twitter.com or identi.ca: e.g., "@username Monkey see monkey do") can be considered as replies. If replies are considered to be comments then the system caters user commenting. However, not all notices are comments (responses, replies) because they are standalone messages. The "@" convention is considered to be a reply since the notice also ends up in that user's replies stream. A side note here: using rel="in-reply-to" on the "in reply to" anchor in notices that lead with "@" creates a linkable comment.

A comment microformat should deal with hierarchically nested comments

  • notes:
  • comments and votes:
    • assuming that there is some kind of explicit, programmably-discoverable link between the comments and the thing being commented on (be it through nesting, an anchor link or some other method), then it is almost unavoidable that a comment microformat would be able to deal with hierarchical comments. After all, a hierarchical set of comments is merely a set of comments such that some of the comments are comments commenting on other comments. (I wonder if I could have avoided using the word "comment" six times in that previous sentence?) TobyInk
    • +1 Yes As all comments that I have looked at DO have a hierarchical structure, some nested inside each other as replies to other comments. I believe in "most" cases XOXO 1.0: Extensible Open XHTML Outlines (<ol> and <ul>) can address the problems of structure and hierarchy, this SHOULD however be totally optional, or maybe just a design note Martin McEvoy

if hAtom Entry is used, the Entry Title if not present should be X

  • comments and votes:
    • +1 Use the author value of the hentry presented in a contextual way, for example by prefixing the author value with "by" or appending it with "said" or "says" Martin McEvoy
    • David Janes I'm happy to have whatever made up by parser implementers, which seems to be the way Atom feeds happen today. I have issues with specing English words, as it's non-I18N friendly.
    • -1 because entry-title doesn't have to be an explicit title that is entered by the commenter. entry-title could be based on the information that already exists e.g., "John Smith commented on 2008-11-24". I don't think making up data (even if it is "X" or null) from thin air to satisfy the parsers is the right approach. This also wasn't the case for regular (non-comment) hAtom Entries. Sarven Capadisli

suggested usage template for above

  • notes
    • bla bla bla
  • test cases covered:
    • 50%
  • comments and votes:
    • +1 this is a great idea - SomeUser
    • -1 this doesn't even work in have the cases - SomebodyElse
      • you don't even know how to spell "half" - SomeUser
