This chapter contains information of use to implementors of NISO STS, who may need to work with the NISO STS Tag Sets beyond merely tagging or receiving NISO-STS-tagged documents. For example, such power-users may need to: make a subset or superset of one of the tag sets, integrate NISO-STS-tagged documents with other tag sets in a database, understand the complex relationship between JATS and NISO STS, add RDF-a or another linked-data mechanism to a NISO STS document, namespace a NISO STS vocabulary, or perform other technical processing.
