Re: Hydra difference to established Web API descriptions

Christian,

like I mentioned, LDT enables declarative Linked Data API definitions
- I think that is the major difference.
With that I mean that all the CRUD logic of such API is contained in
the LDT ontology that carries the definition. A description like Hydra
only describes the surface interface while the logic is hidden away in
the implementation source code.

LDT also has formal semantics. That is, the evaluation of read/write
Linked Data requests against an LDT application is specified formally.
That is quite unique IMO, comparable to algebra definition in SPARQL
for example.
