<h4>What's a metadata ?</h4>
<p>
A Metadata is a data that qualifies another data.<br />
For example, if you have a digital camera, I guess you have now a lot of photo sitting on your pc. Chances are you are going to have trouble finding them if you have not organized them the right way at the beginning.<br />
Recent photo handling/organizing software like <a rel="nofollow" class ="offsite httplnk" href="http://www.digikam.org/">digikam</a>, <a rel="nofollow" class ="offsite httplnk" href="http://ktown.kde.org/kphotoalbum/">kphotoalbum</a>, or <a rel="nofollow" class ="offsite httplnk" href="http://picasa.google.com/index.html">Picasa</a> features keywords. You can add keywords to your photo so you can search by keyword later for example.
</p>
<p>
In this example, keywords are metadatas, it is a data that qualifies a photo. In Wiclear, metadatas are datas that qualifies a particular page. The <a href="http://wiclear.free.fr/?WikiBlog">WikiBlog</a> plugin uses metadatas to add a "category" metadata to the content. This way it is possible to browse the site by metadata using the <a href="http://wiclear.free.fr/?WikiBlog">WikiBlog</a> plugin.
</p>
<p>
Metadatas in Wiclear are quite general so I guess we are going to see things important with them in the future. Right now I must say their use is quite anecdotic : there is currently nothing using them apart to display them (and except the <a href="http://wiclear.free.fr/?WikiBlog">WikiBlog</a> plugin).<br />
In the future, I guess we can add things like :
</p>
<ul>
<li> search by metadata
</li><li> filter content by metadata
</li><li> add html metadatas from Wiclear's metadata so that search engine can better qualifies and index web pages
</li><li> other ?
</li></ul>
<h4>Edit/View metadata</h4>
<p>
Use the metadata link available in the tool box.
</p>
<p>
<img alt="Metadata link" src="http://wiclear.free.fr/images/metadata.png" />
</p>
<p>
This will display current metatas as well as a form to edit them.
</p>

</p>
<p>
As this site is also a demo site, I've defined only two metadatas
</p>
<ul>
<li> test_open_metadata
</li><li> test_closed_metadata
</li></ul>
<p>
In Wiclear metadatas must be defined by the admin which give them a name and a type.<br />
Metadatas can be either
</p>
<ul>
<li> open (like test_open_metadata). In that case you can enter anything you want inside the metadata
</li><li> closed (like test_closed_metadata). In that case, the admin define the list of acceptable values this metadata can bear => it is shown to you as a drop down with a limited set of choice
</li></ul>
<p>
There is no limit to the number of metadatas that can be added : you can define several time the same metadata with different values.
</p>
<p>
For example, the <a href="http://wiclear.free.fr/?WikiBlog">WikiBlog</a> plugin defines a "category" closed metadata and offers an interface in the admin panel to edit the available values. Of course, you could use the more general metadata entry in the admin panel to do the same thing, except that the <a href="http://wiclear.free.fr/?WikiBlog">WikiBlog</a> interface is more user friendly.
