does someone know if there is an official web based documentation of the HDS APIs?
So fare I got only access to PDF based API documentation.
Nowadays it is very common that vendors publish there api documentation in a web based style.
In my opinion HTML is the better format, as it is easy to access, easy to bookmark, easy to share links and to cite from.
There are many tools to build good html based documentation, for example http://swagger.io/
