= Licensing Brainstorming =

The very beginning.

See [[licensing]] for background.


== Discussion ==

Set of classes pertinent to supporting licensing and attribution requirements and complements.  These classes could be used at webpage level or within relevant microformats, e.g., [[media-info]].

The first column may be too URL-centric, see notes for parent work, may apply to others.

<table border="1" cellpadding="3" cellspacing="2">

== Attribution Challenges ==

Tags dealing with specifying sources and tracking a piece of media's path through the Web are a little ambiguous in terms of what they can reference.  For instance when specifying a derivative work it could be from another image on the Internet, in which case an URL would be appropriate, or it could be a quotation from a magazine or other "real" world source where an URL doesn't really work.  Perhaps we can encourage the content of these 'media source' tags to be one of the following:
<table border="1" cellpadding="3">
<tr>
 <th>Media source type</th>
 <th>Format</th>
 <th>Notes</th>
</tr>
<tr>
 <td>Internet source</td>
 <td>An URL</td>
 <td></td>
</tr>
<tr>
 <td>Person</td>
 <td>[[hcard]]</td>
 <td></td>
</tr>
<tr>
 <td>Publication <br />(book, magazine, etc.)</td>
 <td>[[citation]]</td>
 <td>Citation appears to be heavily weighed towards academia but it looks like it should work for most purposes</td>
</tr>
<tr>
 <td>Film/Video</td>
 <td> ?? </td>
 <td>I'm not sure about this one.  Would citation stretch over visual media? Perhaps [[media-info]]?</td>
</tr>
</table>


== Strawman example ==
Perhaps there should be an 'attribution' class which might hint that a fn or url should be used for attribution?  Something like (webpage scope):

<pre>
<nowiki>
<a class="url attribution fn" href="http://example.com">My First Cookbook</a>
<div class="author vcard">
  <div class="fn attribution">J Doe</div>
</div>
<a rel="license" href="http://creativecommons.org/licenses/by/2.5/">(cc)</a>
<a rel="payment" href="http://paypal.com/...">don't let me starve</a>
</nowiki>
</pre>


== Strawman example for media ==

Note the [[media-info]] is not even defined yet, this is not even strawman quality.

<pre>
<nowiki>
<div class="media">
  <img class="url attribution mediaitem" src="http://example.com/cake.jpg"/>
  <span class="fn">Picture of a giant cake</span>
  <div class="author vcard">
    <div class="fn attribution">J Doe</div>
  </div>
  <a rel="license" href="http://creativecommons.org/licenses/by-nc/2.5/">(cc)</a>
  <a rel="payment" href="http://paypal.com/...">don't let me <s>starve</s>eat cake</a>
  <a rel="payment" href="http://artdelivery.example">buy this pic, framed</a>
  <a rel="payment" href="http://photoclearing.example">get commercial rights</a>
  ...
</div>
</nowiki>
</pre>

= Creative Commons Vocab =

Creative Commons has an [http://creativecommons.org/ns RDF vocabulary] which may be suitable for reuse. Here is an example using the Creative Commons vocab. It goes a long way to meeting all the stated requirements.

<pre><nowiki>
<div class="License">
  <a rev="license" href="http://example.org/work">The work</a> is licensed under
  the <a rel="legalcode" href="http://example.org/foo">Foo Licence</a>. 
  Summary: it permits <abbr title="DerivativeWorks" class="permits">derivative
  works</abbr> but requires <abbr title="Attribution" class="requires"
  >attribution</abbr>. The credit to give when reusing the work is "<span 
  class="vcard"><a href="http://tobyinkster.co.uk" class="fn url
  attributionName" rel="attributionURL">Toby Inkster</a></span>".
</div>
</nowiki></pre>

The microformat could use the following terms:

* '''License''' {1} (root class name)
** legalcode ? (rel value, not class)
** ''morePermissions'' * (rel value, not class)
** ''permits'' * ("Reproduction" | "Distribution" | "DerivativeWorks" | "HighIncomeNationUse" | "Sharing")
** ''requires'' * ("CopyrightNotices" | "Attribution" | "ShareAlike" | "SourceCode")
** ''prohibits'' * ("CommercialUse")
** ''jurisdiction'' * (text | hCard | adr)
** attributionName ?
** attributionURL ? (rel value, not class)
** deprecatedOn ? (ISO date)

The license linked to using rel="legalcode" (if any) should be taken to be the definitive license. When such a license is present, the "permits", "requires", "prohibits" and "jurisdiction" classes are taken to be merely advisory. When no "legalcode" license is linked to, these classes are definitive.

[[rel-license]] {{should}} be used to link from the work to the license (an ID attribute on the license will help). A license {{may}} link back to the work using rev="license", but forward links are preferred.

As an extension to the creative commons vocabulary (which focuses on open-source-like licenses) a payment URL {{may}} be linked to using an anchor element simultaneously carrying class="requires" and rel="payment". Example:

<pre><nowiki>
<a class="requires" rel="payment" href="https://payment.example.org">buy</a>
</nowiki></pre>

If [[rel-payment]] is used without a class of "requires", then the link is taken to be an optional payment link - i.e. a donation.
