Fedora Repository 3.4 Documentation - Fedora Repository 3.4 Documentation - DuraSpace Wiki
The latest release of Fedora is now available. Some of the new features:
- DC, RELS-EXT, RELS-INT as Managed Content: The Dublin Core and Relationships datastreams can now be stored as Managed Content, improving performance particularly when these datastreams are large. A migration tool is included to migrate existing inline XML datastreams to managed content datastreams
- REST API relationships methods: New methods in the REST API for adding and manipulating relationships in RELS-EXT and RELS-INT
- Enhanced Content Models: Including the ability to validate objects against their content models, and support for optional datastreams
- Optimistic Locking: The REST API now provides support for optimistic locking to ensure no one else has made a change to an object since you started editing it
- FeSL Authentication: FeSL Authentication can now be used independently of FeSL's experimental authorization mechanism, and is now the default authentication mechanism (although the old mechanism can be specified during installation). FeSL Authorization is still disabled by default.
- FeSL policies as Fedora Objects: XACML policies are now managed in FeSL directly through the Fedora API by manipulating Fedora objects containing a FESLPOLICY datastream
- Logging reconfiguration without restart: Using the new SLF4J and Logback logging framework, logging configuration changes now become effective without having to restart the server
- Akubra low-level storage: Akubra is now considered production-ready and is the default low-level storage module
- REST API improvements and bug fixes: further stabilizing the REST API
- Deprecation of "LITE" APIs: As of this release, the API-A-LITE and API-M-LITE APIs are deprecated, and will be removed in a future release. You are encouraged to migrate any code using these APIs to use the new REST API.
