Re: Layered Data

Hi Leigh,

I'm working on something that might be related, although I'm primarily focused on surfacing the possibilities of data interactions on the UI level. My framework mashpoint (http://mashpoint.net/ see paper: http://events.linkeddata.org/ldow2012/papers/ldow2012-paper-12.pdf) facilitates linking data-powered apps so they can be navigated and combined in a data-oriented way by ordinary users. In your paper you define data layers as "... either a whole dataset or a useful subset". One view of an application in mashpoint its that an data-powered app is simply a rich visual representation of a portion of dataset that can be displayed and interacted with in a particular context. I think then you can see the process of identifying data layers in a dataset, as the process of people selecting portions of the dataset that will be used in the context of a particular app. 

Just my 2 cents.

Best,
--Igor
