capture visibility attribute for ontologies

[carueda]

There are 3 values for the ontology 'visibility' attribute:

1. 'Visible only to the owner'. Depending on the designated owner, this means:
   • only visible to the submitting user when no associated organization is designated as the "owner"
   • only visible to the members of the selected organization
2. 'Visible only to logged-in users'
3. 'Public' (visible to any visitor / API-accessible with no restriction)

The visibility attribute to apply at the version level (not globally to the ontology as a whole).

@graybeal FYI and any comments.

Implemented.

• POST and PUT /ont now accept a visibility parameter. Possible values: "owner", "user", "public". Default value: "owner".
• GET /ont (no specific URI requested): returns list according to requester and visibility as specified.

Note: The visibility attribute is mainly only for purposes of the main ontology listing. So:

• no restriction if specific ontology URI is requested
• triple store always updated with the latest ontology version regardless of its associated visibility

Per discussion today, re-opening to only handle the "owner" and "public" option.
