Adobe CQ5.5 Custom Reporting for Digital Assets (DAM)

[koolgeex1]

I'm using Adobe CQ5.5

I want to know where I would start if I wanted to create reports for assets. One example would be - "List all assets that do no have a reference." Another example would be "List all assets that do not have tags."

Where would I start to make this happen? Is this something that would be easier with AEM (5.6)?

Ok so I've found an example package ( http://www.eyelock.net/blog/archives/572 ) that contains a report that lists out the assets and general information. How would i extend this to make it show if the asset has references and also give the URL of the reference(s).
