Managing metadata in Fedora means considering how best to make use of RDF and Linked Data. Fedora can store metadata in any format, including common formats like XML and JSON. Additionally, Fedora enables RDF properties to be defined for objects it stores or references. This includes all types of metadata, such as technical, rights, provenance, and descriptive. Managing this metadata in Fedora means considering how best to make use of RDF and Linked Data. Some access systems such as Hyrax also provide editing and management capabilities for RDF metadata stored as properties in Fedora. See Common metadata design patterns for examples of ways to take advantage of Fedora's capabilities.
Fedora uses a set of internal properties (see http://fedora.info/definitions/v4/repository) and supplies the following ontologies by default.

- Samvera Community - MODS to RDF Mapping Recommendations (work in progress) - This mapping recommendation offers two paths to transition MODS descriptive XML to RDF properties:
- A direct mapping that provides single RDF statements for MODS concepts without any hierarchy or complexity of graphed relationships. Some MODS attributes and level of detail is lost but these statements can be managed directly with the Fedora object.
- A minted object mapping that preserves the hierarchy and complexity of MODS concepts by creating (minting) new objects for subjects, names, and other descriptive elements representing a graphed relationship. Creates empty objects in the digital repository but MODS attributes and details are preserved.
