Hello Pushparajan,
The Tamino WebDAV Server uses Slide as the central WebDAV engine. All the Slide jar files are packed with Tamino WebDAV Server. The Slide version is 1.0.13 (with some minor bug fixes contained in Slide version 1.0.14).
We do not expose the Slide Content Management API officially and there is the Slide documentation available only. This might be something for further versions. Currently the best source of information would be http://jakarta.apache.org/slide.
Using the installed slide-kernel.jar will give you access to the Slide Content Management API. The API itself is not fully supported by the Tamino store, e.g. no versioning or ACL support yet. Again, this is something for coming versions. For the non-versioned access it will be fully operable, this is the internal API used by the WebDAV layer.
Best regards
Juergen
P.S. If possible I would currently suggest to use the WebDAV protocol or API.
