Re: Seeking LDP server recommendations

I started passing the official test suite on my LDP server, semantic_forms,
and the result is currently:
Total tests run: 90, Failures: 38, Skips: 27 - Passed 25

I'm willing to fix, but the correspondence between the failure messages and
the actual HTTP requests is not obvious, so I made an issue on the test
suite github:
https://github.com/w3c/ldp-testsuite/issues/230

If anyone among the LDP server developers is willing to shed some light ...
That would be nice.
