The scope of CTWG is to assist TOIP working groups (WGs), task forces (TFs), TIPs (i.e. the and other communities of interest or communities of practice that exist within TOIP) both within and outside of the ToIP Foundation to develop the concepts and terms they need for  themselves or for particular projects, and make them available for everyone within (and outside of) TOIPto the public. This includes developing artifacts and tools for discovering, documenting, defining, and (deeply) understanding the concepts and terms used within TOIP. Key deliverables include ways to define terms (e.g. through  terms wikis), maintain a corpus of data underlying these terms, and provide ways to query the corpus to obtain terms e.g. for the creation of glossaries and other artifacts. The data that underlies the terms typically consists of (formally modeled) concepts, plus their relations and constraints, and will encompass perspectives from technical, governance, business, legal and other realms. Although CTWG will maintain this corpus of data via repositories that all TOIP WGs and TFs can contribute to and inherit from, this does not preclude WGs or TFs from maintaining their own specialized glossaries if they require. Such specialized glossaries, together with other generators of concepts and terminology elsewhere in the industry, are expected to feed back into the glossaries and corpus of data maintained by CTWG in a cycle of continuous improvement.
