Titus Labs Metadata
Sharepoint Security allows administrators to build access rules based on the document’s assigned metadata properties. These metadata rules can then be assigned to a document library or content type. Metadata Security can automatically produce specific permissions for each document in the library, without having to do tedious item-level permission assignment.
Because per-document security is much easier to set up, administrators can easily create a Document Library that different groups of users can share. Each group can have different and specific types of permissions.
