An updated version was released in September. Please make sure you are using the most up to date version. Significant revisions are documented in both the application profile and the introduction. A metadata application profile (MAP) adopts elements from multiple standard metadata schema for a particular use. This application profile represents the metadata that OSF stores about its objects: Projects, Registrations, Preprints, and Files. The OSF MAP was created using the Dublin Core Tabular Application Profiles specification. Before reviewing the model closely you may want to read the primer describing the specification: https://github.com/dcmi/dctap/blob/main/TAPprimer.md. If you haven’t worked with metadata application profiles or models before, this will provide an introduction to the structure of the OSF MAP.
