An application profile is a schema composed of metadata elements drawn from one or more namespaces, as well as policies and guidelines related to their use, prepared for a particular application. It reflects a set of recorded decisions about a shared data target for a given community.
For Linked Open Data (LOD) projects, an application profile should provide details about the ontology (classes and properties), vocabularies, and data formats. They should document how data is modelled, declare what entities and properties will be used, and declare the data types for string values, along with scope notes for consistent use of fields and properties. An application profile should clarify the expectations of the data being ingested, processed, and managed, document models and standards, and note where implementation diverges from community standards (UCLA Library).
