What we currently call tags will become "extended metadata".
We will add to the UI simple, flickr-like tagging.

"Manage Tags and Metadata"

• "Manage Tags and Metadata" tab will say "Manage Metadata"
• Popup window title will have same change as above
• Manage Metadata window will be the same, except for wording changes: "category" will become "metadata field"; "tag" will become "value"
• Improve the "Manage Metadata" screen by making there one menu to both add, and select a category, and one menu to add and select a tag.

Item Metadata Screens (edit item/view item metadata/upload/bulk upload)

• All Extended Metadata fields (as created in the Manage Metadata screen) will look like the Dublin Core fields do, except that they will all be drop-down menus. The "Field" name will be the label (like title, contributor, etc.), and the values within that field will show up as options in a drop-down menu

      TAGS:

• The bottom of this page that now says Tags will be simplified, and will be used for simple, flickr-like tagging. There will be no hierarchy of category-tag.
• Tags already assigned to that item are there as clickable text -- clicking on them does a search for all content tagged with the same tag. There will be a little X next to each existing tag to remove it from the item.
• To add a new tag, there will be a simple text box, with instructions underneath to enter tags separated by spaces, and if they want a multi-word tag, to enter it surrounded by quotes.
• There will be a limit to how many tags a user can set on a given item. This will be enforced by the backend. Since it is unlikely a user will reach this limit, I don't think messaging is necessary in the front-end. Limit will be ???

Search

• Extended metadata field names will appear in the drop-down list, as the dublin-core fields do. When selected, the drop-down list of those values will appear as the options (instead of a text box).
  • Question: allow multiple select, or have them create additional rules to specify multiple values?
  • Needs to be clear, in search, that it is an AND rather than an OR

• Tags: there will be a simple text box, and users can enter one or more tags to search against.
  

Possible Features for Later:

1.  Add clickable list of tags to the list-view of items.
2. Add support for extended metadata which permits free-form entry of text as the value. This would require dynamically adding a tag to the given category (invisibly to the user), and raises some access control issues.
