Tag: a keyword or term associated with or assigned to a piece of information

Tagging Support

1) Simple text values that can be arbitrarily added to a CM item (Ex: The provider defines a single text field with a comma delimited list of keywords)

2) Structured values that can only be added from a list of existing tags (Ex: The provider defines a collection of tag objects for each CM item)

Tag Handling

The OSLC layer should abstract the handling of tags so that a common tagging interface is exposed through OSLC.

Consumers should be able to:

1) Retrieve a collection of tags that are applied to a particular CM item

2) Add/Remove a tag from the collection of tags for a particular CM item

3) Query a repository and return a collection of CM items that have a specific tag or list of tags applied to them

4) [Optional] Retrieve the list of all available tags for a repository. (This may return no tags or not be implemented by the provider)

5) [Optional] Add a tag to the list of available tags for a repository. (This might not be implemented by the provider)

6) [Optional] Remove a tag from the list of available tags for a repository. (This might not be implemented by the provider)
