- About the Authors
Metadata application profiles (MAPs) are discussed in two broad categories depending on whether or not they adhere to linked-data practices. There exist a broad range of purposes for MAPs, including metadata implementation and interoperability. MAPs have 4 components: the application, entities, properties, and values. MAP creators gather MAP components from already existing sources, including ontologies, schemas, vocabulary encoding schemes, and syntax encoding schemes. Implementers may present MAPs in human-readable, machine-readable, and hybrid formats. Several examples in the text demonstrate specific MAP features.
