| [fac] However, when vocabularies are shared, the user may need some of the same concepts and may have new concepts to add. The fundamental problem is for the user to determine if there is a concept already defined or if a new concept is needed. If the shared vocabularies include a vocabulary in a language familiar to the user then the search for a defined concept is easier, but candidate concepts may still not meet the user's requirement. If there is no familiar-language vocabulary, then the user has a more difficult problem. We might assume that there is an appropriate vocabulary for the modeling language, but the user will still need the help of somebody who can interpret definitions in one of the existing vocabularies.. | [fac] However, when vocabularies are shared, the user may need some of the same concepts and may have new concepts to add.

| + | [fac] Note that a vocabulary library (a set of vocabularies) will have one concept element for each concept that is linked to the element for the associated term in each vocabulary. Consequently, when a user wants to use and existing vocabulary library, either for a new model or to add vocabularies to an existing library, There is a need to support a mechanism for finding a concept if a needed concept exists in the library. A couple approaches are possible: (1) provide a thesaurus to group similar concepts (requires the user to update the thesaurus when adding a concept), or (2) provide a taxonomy/classification network that traces general concepts to more specific concepts (easier for the user to update for new concepts). | ||
| + | [fac] Defining a global identifier for each concept does not help since the user must still search for a desired concept and possibly refine an existing concept definition to distinguish a new concept. | ||
