GRASP ("Graph for SharePoint") is the SharePoint solution that brings professional terminology management to the SharePoint term store. You can import and update terminologies from external systems (in SKOS) that can be deployed into termstores. You can revise terminologies directly and collaboratively in SharePoint. You can create working copies of terminologies that are modified directly in SharePoint by your users before they take effect in the managed metadata. You can create complex models, e.g. medical terminologies, that include poly-hierarchies. Poly-hierarchies are considered in the SharePoint search. Regular users can browse terminologies outside the termstore manager in a convenient terminology browser.
GRASP is the term store management tool!
