    How difficult would it be to display a tag cloud of tags specific to a collection. Right now I can browse items in a collection, but if I browse by tag, I get the tags from the entire archive.

    (I'm working on building this site with a FYC class.)

    Is there a tag class? Would one loop over the collection, grabbing tags from each item in a collection and adding them to an array of some sort, using tag_cloud to display the cloud?

    Any suggestions on how to implement this or (better) whether it is easily implementable would be much appreciated.

    Hi Chris,

    There is no built-in way to do this, but you can write a custom query for it. I created a function that filters the tags list based on items in a specific collection. Checkout the gist on my GitHub account. Just include this custom function in your theme's custom.php file, or in a new plugin. Once you include that function somewhere, you'd need to do something like this on your collections/show.php template to use it:

    <?php
$collectionTags = get_tags_for_items_in_collection();
echo tag_cloud($collectionTags,uri('items/browse'));
?>

    We may update Omeka in a future release to allow this kinds of custom queries on tags, but in the meantime I hope this helps you out.
