Hi Ghanshyam,

Once the new JAX-RS based REST interface is in place (its not there yet, 
but will come in soon), you can use following ways to retrieve rules 
under a category. For example:

A HTTP GET request to URL http://host:portnumber/repository/categories 
with Accept="application/atom+xml" returns a list of categories in the 
repository in Atom Feed format.
 
A HTTP GET request to URL 
http://host:portnumber/repository/categories/testCategory1/assets with 
Accept="application/atom+xml" returns a list of assets under the 
testCategory1 in the repository in Atom feed format.

A GET request to 
http://host:portnumber/repository/categories/testCategory1/assets/testAsset1 
with Accept="application/atom+xml" returns an atom entry which is a 
summary info of that asset as well as its meta data.

A GET request to 
http://host:portnumber/repository/categories/testCategory1/assets/testAsset1 
with Accept="application/octet-stream" returns a binary attachment (if 
that asset has a binary attachment as content).

A GET request to 
http://host:portnumber/repository/packages/testPackage1/assets/testAsset1 
with Accept="application/source" returns the asset source in text format 
(if that asset has a content in text format).

A GET request to 
http://host:portnumber/repository/packages/testPackage1/assets/testAsset1 
with Accept="application/json" returns a json object which is the 
summary info of that asset as well as its meta data.

Will this meet your requirement?

Thanks,
Jervis
