newbe on usage of low-level (non webdav) client API

[Eelco Hillenius <ee...@topicus.nl>]

Hi all,

I am quite new to Slide and I am having a hard time finding out the best way
of using it. I have just started building a CMS application that uses Slide
for a content repository. The first question that arises is whether I should
use the WebDav API or the lower level API? I assume that, as my both code
and Slide will run in the same VM, it will be much better performance-wise
to use the lower level API. Is that right?

The second question is if, using the plain client API, the test class that
you can find below shows the correct usage of the API. I am just trying to
add, retrieve and remove a file (named test.xml). The test runs fine...(data
shows up in RDBMS) but I have got the feeling I am doing too much. And I do
not understand that if I want to get things working I have to do something
like: structureHelper.create(slideToken, rootuser, "/files/test.xml"); This
adds the SubjectNode rootuser. I would rather just add a file node or
something... But I probably just do not understand some of the concepts of
the Slide API. Maybe I have to implement my own types of ObjectNodes?

Could someone please help me on this? Cheers,

Eelco Hillenius
