Examples of such sets include attributes, %%Claims/Assertions|assertion%%, files/dossiers, %%(verifiable) credentials|credential%%, %%(partial) identities|partial-identity%%, etc.Note that without this data set, the use of this term is meaningless. Therefore, %%subject|subject%% must be seen as a relation (between a data set and an %%entity|entity%%), rather than as this %%entity|entity%% itself (as is commonly done).Sometimes, the term 'subject' is also used in the meaning of 'reference to the (single) %%entity|entity%% [etc.]' or '%%identifier|identifier%% for the (single) %%entity|entity%% [etc.]' rather than the (single) %%entity|entity%% itself. We discourage such practices, and suggest to use the term 'subject identifier' in such cases.### Purpose
The term **subject** provides a generic way to link %%entities|entity%% that exist in the real (physical) world with %%knowledge|knowledge%% about them (e.g. characteristics, %%partial identities|partial-identity%% and such) that exists in the minds of various %%parties|party%%.
