== Purpose ==
A microformat to describe the contents of a (we)blog. It provides a specific set of information to categorize a (we)blog. Enables easier search for humans and efficient collection of information by machines.
 
Here are some of examples for information that might be provided:
 
* Details about the blog
* Blog name (e.g: "John Doe's Blog")
** Blog URI (e.g: http://example.org/ )
** Lanuage used for the blog, read-able by machines (e.g: "en-US" or "de")
** Topics covered by the blog
** A short description
** Available feeds (RSS, Atom, etc.)
** A small logo image
* Details about the author(s)
** Name (e.g: "John Doe")
** Organisation
** Contact details
** Geographical Location
 
== Theoretical examples ==
 
<pre><nowiki>
<div class="blogformat" xml:lang="en">
  <p><img class="logo" alt="" src="http://rbach.priv.at/Misc/2005/Smiley.gif" />
  <a class="author" href="http://example.org/jdoe">My</a>
  <a class="bookmark" href="http://example.org/blog" title="John Doe's Blog">blog</a>
  about
  <span class="description">
  <a rel="tag" href="http://technorati.com/tags/web+standards">Web standards</a>,
  <a rel="tag" href="http://technorati.com/tags/css">CSS</a>,
  <a rel="tag" href="http://technorati.com/tags/xhtml">XHTML</a>
  and topics releated to web development.</span></p>
  <p>There are
  <a rel="alternate" type="application/atom+xml" href="http://example.org/feeds/atom">Atom</a> and
  <a rel="alternate" type="application/rss+xml" href="http://example.org/feeds/rss">RSS 2.0</a>
  feeds available.</p>

== Strawman proposal ==
 
Text in ''italics'' is used as reference to the comments below.
 
=== Blog information container ===
 
The blog information container element contains all other elements of the blog description.
 
It '''must''' have a class attribute which includes the value <code>blogformat</code>.
 
=== Language ===
 
The blog information container element or an ancestor element ''(langanc)'' of it '''must''' include
a language code using the <code>xml:lang</code> attribute to indicate the language used for the blog.
 
If the document type used by the author allows the usage of the <code>lang</code>
attribute, it must be used to specify the language code.
The value '''must''' be equal to the one used for <code>xml:lang</code>. ''(langequ)''
 
Example 1:
<pre><nowiki>
<!-- A blog written in English as spoken in the US -->
<div class="blogformat" lang="en-US" xml:lang="en-US">
    <!-- child elements -->
</div>
</nowiki></pre>
 
Example 2:
<pre><nowiki>
<!-- A blog written in French -->
<div class="blogformat" lang="fr" xml:lang="fr">
    <!-- child elements -->
</div>
</nowiki></pre>
 
=== Blog URI ===
 
The blog URI element '''must''' be an <code>&lt;a&gt;</code> element and '''must''' contain a <code>rel</code> attribute which includes the value <code>bookmark</code>.
 
It must link to the blog's mainpage using an absolute URI ''(absuri)''.
 
This element '''should''' provide the name of the blog in its <code>title</code> attribute.
 
If no <code>title</code> attribute is provided agents ''(agents)'' '''must''' use the text value of the blog URI element ''(meta)''.
 
=== Blog description and topics ===
 
It contains the main categories covered by the blog.
 
The categories are marked up within anchors ''(cat)'' that (may) refer to technorati-tags.
 
Example:
<pre><nowiki><a rel="tag" href="http://technorati.com/tags/xhtml">XHTML</a></nowiki></pre>
 
In addition authors can write up a short introduction.
 
=== Author information ===
 
Information about the author '''should''' be provided.
 
The author information element '''must''' have a class attribute which includes the value <code>author</code>. This element '''should''' provide the name of the author
in its <code>title</code> attribute.
 
Example:
<pre><nowiki><span class="author" title="John Doe">John's</span> Blog.</nowiki></pre>
 
If no <code>title</code> attribute is provided agents ''(agents)'' '''must''' use the text value of the author information element ''(meta'').
 
The author information element may be an <code>&lt;a&gt;</code> element which links
to the author's page using an absolute URI ''(absuri)'' or may be some other element containing
an [[hcard]].
 
Example:
<pre><nowiki>
<a class="author" title="John Doe"
  href="http://example.org/~johnd/">John's</a> Blog.
</nowiki></pre>
 
=== Feeds ===
 
''To be done.''
 
Perhaps using 
<a rel="alternate" type="application/atom+xml" href="http://example.org/feeds/atom">Atom</a> 
<a rel="alternate" type="application/rss+xml" href="http://example.org/feeds/rss">RSS 2.0</a>
 
(Maybe the already used 
<link rel="alternate" type="application/rss+xml" href="http://example.org/feeds/rss" title="RSS 2.0" />
is enough? --RobertBachmann
)
=== Image ===
 
''To be done.''
 
=== Comments ===
* (langanc): There are XHTML documents which already have their language specified in the &lt;html&gt; tag. In this case it would be redundant to require having it twice. --[[User:RobertBachman |RobertBachmann]]
 
* (langequ): See http://microformats.org/discuss/mail/microformats-discuss/2005-July/000440.html. --[[User:RobertBachman |RobertBachmann]]
 
* (absuri): As long as we are parsing blog information from the original URI, handling relative URIs isn't a big problem. I think we should recommend the use of absolute URIs ("absolute URIs '''should''' be used") but I'm not sure if we should require them. --[[User:RobertBachman |RobertBachmann]]
 
* (agent): Is agent the right term?  --[[User:RobertBachman |RobertBachmann]]
 
* (meta): Perhaps agent would want to extract information from <code>&lt;head&gt;</code> if no information can be found within "blogformat"
**<code>&lt;link rel="author" href="http://example.org/~jdoe" /&gt;</code>
**<code>&lt;meta name="author" value="John Doe" /&gt;</code>
**<code>&lt;title&gt;John Doe's Blog&lt;/title&gt;</code>
--[[User:RobertBachman |RobertBachmann]]
 
* (cat): '''May''', '''should''' or '''must''' they be within anchors. What are the options where they can point to? --[[User:BjoernSeibert |BjoernSeibert]]
