== format ==
* Authors should provide one "item-url" for an external resource that is being licensed.
 
* If more than one "item-url" is provided, they are assumed to be copies/mirrors/versions (perhaps different resolutions or formats) of the same item, and all have the same license(s) and attribution terms (if any) applied to them.

+
=== root class name ===
E.g. a link to the photo and embedding a thumbnail or small version of the photo:
+
The root class name for item-license is <code>item</code>.
 +
 
 +
A simple item can be indicated as follows:
 +
 
 +
<source lang=html4strict>
 +
<span class="item">
 +
...
 +
</span>
 +
</source>
 +
 
 +
As with other microformats, the particular element (span, div, etc.) doesn't matter for item-license.
 +
 
 +
=== properties ===
 +
The following properties can be specified as class names unless otherwise indicated.  All properties are optional and may occur more than once.
 +
 
 +
* '''<code>item-license</code>''' - a rel-value used on a hyperlink to a license for the item. multiple instances indicate independent licensing options.
 +
* '''<code>item-url</code>''' - an external representation of the item that is licensed, such as an image, video, audio, binary download, etc.
 +
* '''<code>attribution</code>''' - an author/creator (which {{should}} be represented with an [[hCard]], possibly with a URL to the person/organization) to be attributed for the item. if "attribution" is specified directly on a hyperlink, the hyperlink represents a link to a page with the item and copyright information for the item.
 +
 
 +
=== property details ===
 +
==== item-license details ====
 +
* Authors {{should}} provide at least one "item-license".
 +
* If there is no item-license link in the item, then the item is not explicitly licensed.
 +
==== item-url details ====
 +
* Authors {{should}} provide at least one "item-url" when an external resource is being licensed.
 +
* If more than one "item-url" is provided, they must be considered copies/mirrors/versions (perhaps different resolutions or formats) of the same item, and all have the same license(s) and attribution terms (if any) applied to them.
 +
==== attribution details ====
 +
* If "attribution" is directly specified on a hyperlink (<code>&lt;a href&gt;</code>), the "href" indicates the suggested link to the original item that is being licensed and contains copyright information for the item being licensed.
 +
* if it is on an hCard, the "fn" of the hCard indicates the name of an author/creator of the work, and the "url" indicates the URL that is suggested for linking to their name (prefer the first "url" with "uid" if any, otherwise the first "url" if the hCard has more than one).
 +
* if "attribution" is on an element that is neither a hyperlink nor an hCard, then the element indicates the name of an author/creator of the work

<entry-title>item-license</entry-title>

item-license is one of several Licensing brainstorm proposals, per the microformats The microformats process towards developing a licensing microformat for authors to indicate licenses to portions of pages or external resources like images.

summary

This proposal (re-)uses the containing/root class "item" (see also hReview 0.4 (in progress), hListing draft, hProduct) to indicate the scope of the thing that is being licensed, rel="item-license" to indicate the specific license(s), "item-url" to license one or external resources like images, and "attribution" to indicate attribution information.

content portion licensing

Here is an example of a chunk of hypertext content that is being licensed:

<div class="item">
  <p>... blog post or article text content ...</p>
  <p>This is licensed under a
  <a rel="item-license" href="http://creativecommons.org/licenses/by-nc/3.0/">
   Creative Commons attribution non-commercial 3.0 license</a>.
  </p>
</div>

external resource licensing

To specify a license on an external resource like a photograph, we can use a new class name "item-url" to identify the external resource as being the actual item:

<div class="item">
  This 
  <a class="item-url" href="photo.jpg">photograph</a>
  is licensed under a
  <a rel="item-license" href="http://creativecommons.org/licenses/by-nc/3.0/">
   Creative Commons attribution non-commercial 3.0 license
  </a>.
</div>

format

root class name

The root class name for item-license is item.

A simple item can be indicated as follows:

<span class="item">
...
</span>

As with other microformats, the particular element (span, div, etc.) doesn't matter for item-license.

properties

The following properties can be specified as class names unless otherwise indicated. All properties are optional and may occur more than once.

  • item-license - a rel-value used on a hyperlink to a license for the item. multiple instances indicate independent licensing options.
  • item-url - an external representation of the item that is licensed, such as an image, video, audio, binary download, etc.
  • attribution - an author/creator (which SHOULD be represented with an hCard 1.0, possibly with a URL to the person/organization) to be attributed for the item. if "attribution" is specified directly on a hyperlink, the hyperlink represents a link to a page with the item and copyright information for the item.

property details

item-license details

  • Authors SHOULD provide at least one "item-license".
  • If there is no item-license link in the item, then the item is not explicitly licensed.

item-url details

  • Authors SHOULD provide at least one "item-url" when an external resource is being licensed.
  • If more than one "item-url" is provided, they must be considered copies/mirrors/versions (perhaps different resolutions or formats) of the same item, and all have the same license(s) and attribution terms (if any) applied to them.

attribution details

  • If "attribution" is directly specified on a hyperlink (<a href>), the "href" indicates the suggested link to the original item that is being licensed and contains copyright information for the item being licensed.
  • if it is on an hCard, the "fn" of the hCard indicates the name of an author/creator of the work, and the "url" indicates the URL that is suggested for linking to their name (prefer the first "url" with "uid" if any, otherwise the first "url" if the hCard has more than one).
  • if "attribution" is on an element that is neither a hyperlink nor an hCard, then the element indicates the name of an author/creator of the work

more examples

The following examples illustrate how the properties interact, and multiple uses of properties.

multiple resolutions licensing

multiple item-url properties:

e.g. a link to the photo and embedding a thumbnail or small version of the photo:

<div class="item">
  This 
  <a class="item-url" href="photo.jpg">photograph:
   <img class="item-url" href="smallphoto.jpg" alt="small version of a photograph" />
  </a>
  is licensed under a
  <a rel="item-license" href="http://creativecommons.org/licenses/by-nc/3.0/">
   Creative Commons attribution non-commercial 3.0 license
  </a>.
</div>

attribution example to an author

<div class="item">
  This 
  <a class="item-url" href="photo.jpg">photograph</a>
  is licensed under a
  <a rel="item-license" href="http://creativecommons.org/licenses/by-nc/3.0/">
   Creative Commons attribution non-commercial 3.0 license
  </a>.
  Please attribute the photo to <span class="attribution">Mary Smith</span>
</div>

with an hCard 1.0 for the author:

<div class="item">
  This 
  <a class="item-url" href="photo.jpg">photograph</a>
  is licensed under a
  <a rel="item-license" href="http://creativecommons.org/licenses/by-nc/3.0/">
   Creative Commons attribution non-commercial 3.0 license
  </a>.
  Please attribute the photo to 
  <span class="attribution vcard">
    <span class="fn">Mary Smith</span>
  </span>
</div>

with a hyperlinked hCard 1.0 for the author:

<div class="item">
  This 
  <a class="item-url" href="photo.jpg">photograph</a>
  is licensed under a
  <a rel="item-license" href="http://creativecommons.org/licenses/by-nc/3.0/">
   Creative Commons attribution non-commercial 3.0 license
  </a>.
  Please attribute the photo to 
  <span class="attribution vcard">
    <a class=" fn url" href="http://mary.example.com/">Mary Smith</a>
  </span>
</div>

attribution example to original and author

multiple attribution properties:

<div class="item">
  This 
  <a class="item-url" href="photo.jpg">photograph</a>
  is licensed under a
  <a rel="item-license" href="http://creativecommons.org/licenses/by-nc/3.0/">
   Creative Commons attribution non-commercial 3.0 license
  </a>.
  Please attribute the photo to 
  <span class="attribution vcard">
    <a class=" fn url" href="http://mary.example.com/">Mary Smith</a>
  </span>
  and link to 
  <a class="attribution" href="http://mary.example.com/photo123/">the original photo page</a>.
</div>
