This proposal consists of adding a new language module named Users to provide multi-user support in NCL, proposing three new NCL elements: userBase, userAgent and userProfile. user-Base is used for declaring user and their profiles. userAgent identifies a user and userProfile represents a description of the user’s profile. Each userAgent is associated with only one userProfile, and together, they allow representing a unique user. The user description with its specific characteristics can be loaded from a profile specified with the Resource Description Framework (RDF) standard, for example.
