Re: Hydra difference to established Web API descriptions

Martynas,

I don't think I understood you yet. Can you give a short example on what
I can do with LDT and not with Hydra?

If I understood you correctly, the difference is that LDT enables more
insight into the service and answers the question:"What is the service
doing".

So with LDT it would be possible to gain information about the Web
services internal functionality?

Not sure if I understood you.
