The intended purpose of the Subject Tags metadata item is to facilitate searching for and classification of documents in the Trust and Identity repository. While the initial repository platform does not fully enable automation of this functionality, Subject Tags will be maintained in a manner that can be leveraged in the future at such a time that a platform with more support for searching and classification is in place.
The classification of documents will be coordinated across the repository. For this reason, the "vocabulary" of classification names (i.e., Subject Tags) will be administered by the Repository Librarian. See Subject Tag Vocabulary for the current classifications, and Administering the Vocabulary, below, for how new classifications are added to the vocabulary.

The current subject tags are defined in the following table. In general, meanings of subject tags should be interpreted broadly; if a document addresses issues related to a subject tag, that tag should be added to the document.

Subject Tags are administered by the Repository Librarian in an incremental fashion. When it appears that there are, or will be, a reasonable number of documents that are related to a common topic, a tag is created for them. What constitutes a "reasonable number" will be subjective, depending on the topic, but would generally be expected to be at least a 3-5.
In order to facilitate migration to potential future repository platforms, the syntax of Subject Tags will be kept simple:
- Subject Tags will contain only lower-case characters.
- Subject Tags will contain no white space. When more than one word is required for a subject tag, the words will be concatenated with no spacing.
