Hi

If you're willing to use a work in progress, there is semantic_forms :
https://github.com/jmvanel/semantic_forms/blob/master/scala/forms_play/README.md#play-framework-implementations
Bug reports welcome.

I have not passed an official test suite ( is this the one ?
https://w3c.github.io/ldp-testsuite/ ) .

SF is a sparql database, which stores the LDP data (every LDP resource is a
named graph).
SF has other interesting features:

SF is open source, installed from a zip, whose only prerequisite is Java 8.
You can use the Sandbox at
