How to use the lithium Linux framework with the listed collection list and changing the collection in the model

I want to use a lithium framework to create my application configuration interface, because I like its minimal approach and document-oriented storage model (e.g. Mongodb).

However (and I know that it has not yet been released), there is little information, tutorials or examples to move you from a simple blogging tutorial.

What I'm trying to do now is to create an application that will show me the collections that I have in Mongodb, and then let me work with the collection that I select. I can't seem to understand:

a) how would I build a model that lists collections - preferably in accordance with my internal naming scheme,

b) How can I break the agreement model to indicate the name of the collection used?

I think that there are two things that I come across in order to answer these two questions - perhaps a fundamental misunderstanding of how to move a model in MVC beyond the scope of simple model-model management model examples, and secondly, the actual process of telling the source mongo data on which collection to use.

any pointers or examples gratefully received.

update ::

So, I figured out how to install the collection - for reference, you can set the source in the $ _meta array as follows:

protected $_meta = array(
    'source' => '<<collectionName>>'
);

still don’t know how to use a model that will show me all the collections that I have in my database. Any ideas how to do this from a philosophical or technological point of view?
