 * Hi David I’m trying to suss out a combination of syntax that will give me a clickable
   list of tags per mla_gallery item (selecting only PDFs).
 * I’ve added attachment tags for each of my media items, and I’m wondering what
   syntax will render a list of clickable tags (ie querying WP for matches that 
   tag), and also the category attached to each media item.
 * I tried
    `exif:EXIF_ALL` and `exif:IPTC_ALL` in a markup template but nothing
   shows up there (unless I botched the syntax)
 * Is there a “showzall” syntax that would lay out the whole buffet, (perhaps annotating
   also the required syntax?) enabling mix’n’match for MLA Gallery template coding?

 * The `[mla_gallery]` shortcode can give you a clickable list of the Media Library
   items that match one or more tags, but there’s no capability to generate a list
   of the tag, category or other taxonomy terms themselves. The closest match to
   your requirements is this support topic:
 * [template query for att. tags](http://wordpress.org/support/topic/template-query-for-att-tags)
 * I’ll have to give this idea some thought…
 * The “ALL_EXIF” and “ALL_IPTC” (not EXIF_ALL, IPTC_ALL) values are only available
   in the IPTC/EXIF mapping rules (Come to think of it, I’m going to add them to
   the `[mla_gallery]` shortcode in a future release).
 * To use them, go to the Settings/Media Library Assistant tab and click the IPT/
   EXIF tab. Then scroll down to the “Add a new Custom Field and Mapping Rule” area
   and define a new rule to map this data into a custom field (type “ALL_EXIF” or“
   ALL_IPTC” into the EXIF value text box). Once you’ve mapped the data into a custom
   field, you can go to the “Custom Fields” tab and define a rule that makes the
   custom field available as a column in the Media/Assistant submenu table.
 * However, that only works for images; metadata for PDF documents isn’t available(
   yet).

 * Thanks David I’ll see what I can derive from that post.

 * I have released version 1.50, which adds the ability to extract metadata from
   PDF documents.
 * You can use the “pdf:ALL_PDF” pseudo variable to extract a summary of the metadata
   available for a given item, along the lines outlined above.
 * I am leaving this item unresolved for now, and continuing to think about a capability
   to generate a list of the tag, category or other taxonomy terms attached to each
   media item.
 * Please let me know if you have any problems with or further questions about this
   new feature. Thanks again for your interest and for your suggestion.

 * I have released version 1.81, which includes a new “ids” parameter for the `[
   mla_tag_cloud]` shortcode. The new parameter lets you specify a list of one (
   or more) attachments and generates a cloud with only those terms assigned to 
   the attachment(s).
 * I am marking this issue resolved, but please update it if you have any problems
   or further questions.
 * Thanks for your interest in the plugin and especially for your patience in awaiting
   the item-specific term list enhancements.
