<h1>listing microformat brainstorming </h1>
This is brainstorming for a [[hlisting]] microformat per the [[process]].

{{TOC-right}}

=== Revised Base Schema Elements (proposed) ===

*hListing (hlisting)
** listing action. optional. one or more tags, suggested set: sell | rent | trade | meet | announce | offer | wanted | event | service
** lister. optional. hCard | (fn || email || url || tel).
** dtlisted. optional. ISO8601 absolute date time.
** dtexpired. optional. ISO8601 absolute date time.
** price. optional. text. [should include a floating-point number with optional ISO currency codes] - see the currency proposal
** summary. optional. text.
** '''description'''. required. text with optional valid XHTML markup.
** item tags. optional. keywords or phrases describing the item being offered, using rel-tag
** permalink. optional. 
** availability. optional. text.
** condition. optional. text. examples: 'new', 'used', 'refurbished'.
** shipping. optional. text. text describing shipping and fulfillment


==== Items removed ====
* version. optional. text.

<div class=discussion>
* +1 I'm tending to agree with the removal of version, as in practice it has not been necessary for either [[hReview]] or [[hListing]].[[User:Tantek|Tantek]] 17:45, 16 April 2009 (UTC)

* item info. optional. (fn || url || photo || geo || adr) | hCard (for person or business).

<div class=discussion>
* Removal of <code>item</code> seems to be a mistake, as that is used to indicate the item itself being listed. E.g., a nested <code>hProduct</code> would be <code>&lt;p class='item hproduct'>&lt;/p></code>. Removal appears to leave no way to include ''what'' is being listed. --[[User:BenWard|BenWard]] 17:38, 16 April 2009 (UTC)
** +1 completely agreed with Ben Ward's point. Wide use of [[hReview]] in the [[hreview-examples-in-wild|wild]] has shown that having an explicit "item" is both necessary and works in practice. [[User:Tantek|Tantek]] 17:40, 16 April 2009 (UTC)
* Indeed it was a mistake... left it out of my edits. Replaced. [[User:JayMyers|JayMyers]] 21:04, 22 April 2009 (UTC)
</div>

==== Items added ====
<div class=discussion>
* Each of the following should cite the analysis made of real world examples that demonstrates the 80%+ use case need, otherwise, they should not be added. [[User:Tantek|Tantek]] 17:45, 16 April 2009 (UTC)

* availability. optional. text.
* condition. optional. text. examples: 'new', 'used', 'refurbished'.
* shipping. optional. text. text describing shipping and fulfillment

==== Items changed: ====
* listing action => optional. if omitted, action assumed to be sell 
* lister => optional. if omitted, the buyer/seller is assumed to be the site where the microformat exists
<div class=discussion>
* In that case, an algorithm should be provided for how to determine the hCard for the lister, if no explicit lister is given. [[User:Tantek|Tantek]] 17:45, 16 April 2009 (UTC)
