FEDORA 3.6 SOFTWARE RELEASE: Updated web services framework, Spring-based configuration
The new release of Fedora repository 3.6 features updated web Services framework, increased standards support and expanded Spring-based configuration.
Release notes: https://wiki.duraspace.org/
The following features and changes in Fedora's flexible and extensible repository software are part of Fedora 3.6 release improvements.
• Updated Web Services framework. Fedora 3.6 incorporates work from the Google Summer of Code project to move from the aging Axis 1.3 library to Apache CXF. This allows Fedora to support Message Transmission Optimization Mechanism (MTOM), which provides a 33% size efficiency over Base64 encoded transmission making it easier to add content.
• Support for lowlevel storage metadata. Fedora now includes a hints provider API, allowing implementations to pass such metadata as mimetype or collection membership to be passed to the low-level storage module.

• Expanded Spring-based configuration. Support for Spring configuration of Fedora has been expanded to include the Server module, SOAP and REST APIs.
• Oracle support for MPTStore. Fedora includes the latest Trippi and MPTStore libraries, adding support for Oracle as the backing database for MPTStore.
• REST API support for the getDatastreams method. The REST API now supports the API-M getDatastreams method. All of the SOAP API-M methods are now supported by Fedora's REST API.
• Experimental support for upstream authentication. Fedora includes a new upstream servlet filter which allows for integration with external authentication systems (e.g. single-sign-
• Updated REST API Validation failure response codes. If a REST API management operation results in a validation failure (e.g. ingest FOXML validation, validation failure via the DOObjectValidator module) the HTTP response code is now 400. Previously Fedora reported a generic Server Failure 500 response code. The response body indicates the nature of the validation error.
• Legacy authentication module End of Life. The legacy authentication module, deprecated since Fedora 3.4, will be phased out in the next Fedora release.
• Deprecation of fcrepo-client-
