The Spring-TMF630 project is an extension of the Spring HATEOAS library.
It supports a new media type, that complies with TMF630 REST API Design Guidelines, Part 3. This TM Forum document describes a standard for adding hypermedia links to your JSON-formatted REST resources, following one of the core principles of REST. It draws heavily on HAL and Hydra, taking and mixing the best of them. Spring HATEOAS already supports several media types such as HAL and provides space for community-based ones. Spring-TMF630 has been developed with this community orientation in mind to promote and facilitate better REST API practices.
