Categorical attributes and automated indexing

[greg-wiltshire]

Feature Request

Description of Problem:

Once information is add to objects in TRAC there is no way that a comprehensive list of an attribute's values stored in a tenant can be retrieved.

This provides restrictions on user interfaces. For example if you want to show a list of users that have run jobs so one user can be picked and all of their jobs listed - then this can not be done. It is not possible to get a list of all users from the TRAC API.

Potential Solutions:

• Extend the attribute API to enable attributes to be classed as categorical.
• Auto index these attribute values.
• Expose an API endpoint to enable retrieval of the full list of attribute values.
• Since attributes could be quite large and complex it would seem sensible to only enable this for BasicType attributes (string, integer etc.) and for only string lengths below a length limit.
