This is what we are doing in our Raster Storage Archive (RSA [1] / SpatialCube 
[2]). We have code for constructing an NCML dataset in-memory, and it's 
available under the GPL v3. The code to look at is in this directory:

https://github.com/VPAC/rsa/tree/master/src/storagemanager/src/org/vpac/ndg/datamodel

- AggregationDefinition is the data model (XStream-based)
- AggregationFactory has methods for constructing the model
- AggregationOpener converts the model to NCML and opens the aggregated dataset

There's also RsaAggregationFactory which has special code for interacting with 
our data store.

Cheers,
Alex
