Personal Vocabularies in taxonomy

Just capturing some ideas from earlier this year

--------------------------------------------------
[Moshe on devel list - 5/30/02]
Marco has released a fine image.module, but I need it to do even more. But first, he asked me to kick off a discussion here about personal vocabularies and taxonomy.

Image.module currently enables each user to have a 'personal gallery' which is like a photo blog. I want this module to go even further, and allow users to post their own personal photo albums. An album is just a grouping of images.

Image.module considers each photo as a node. It achieves albums by associating images with term(s) in a vocabulary. So it would seem that the cleanest way to allow users to have personal albums is to let them create their own vocabulary. Personal vocabularies might also be helpful in allowing users to group their own bookmarks or classify their own blog entries [1], [2].

PROPOSAL
- add a field in terms and vocabularies which states the uid of its owner.
- Public terms/vocabularies have no owner.
- we expose a UI to users for add/delete/edit personal terms and
vocabularies (if user has sufficient permission). perhaps this UI is simpler than the one currently in Admin -> Taxonomy
- when a user is composing a node, we display the union of personal and public taxonomies on the compose form
- if a user has no personal vocabularies, drupal looks exactly as it does today
- we display a Block showing the author's personal taxonomy when viewing his personal blog and his user account page. This is easily done in the new taxonomy_html.module
- admins may choose to create links between a private term and a public term
using the 'related terms' feature. see [1], [2] below.
- in Taxonomy Admin, we have 2 overview links. 1 is public taxonomy overview (same as current) and the other is private taxonomy overview. private overview is the page where an admin can browse the vocabularies/terms of his
users.

NOTES
- is there any need to allow multiple personal vocabularies? I think there
is, considering that image.module might use up a whole vocabulary

I don't think the admin page could be made easier without losing some

functionality. Yet a taxonomy user page should be made easier, so we should strip something. We could also give a different interface, perhaps based on a wizard.

I'd prefer "links" which could also be something different from "related terms". think about unix links. we could have a public term, and several private terms linking to it. the concept of link is important because the user already categorized his content, and this is info we want to keep.

I agree on everything else
