Support for Cayenne almost in Isis
Just a quick note.
I'm almost done with implementing support for Cayenne[1] as a data
object store in Isis[2].
I'll not support extra Isis Objectstore query methods, rather I'll expose
the Cayenne query interface as a service.
Additionlly, I'll not support ant datatypes other than those native to
Java / Cayenne.
Regards,
Kevin

as a cheap-and-cheerful first-cut, you could just save them as strings
using the EncodableFacet. This is how the XML object store works, if I
recall.

Once I figured out how Cayenne created tables and fields, it was
relatively straght forward to use ObjectSpecification.getAssociations()
to make further progress.
My initial implementation is only going to work for value types, I'll have
to see how it goes for entity relationships. Cayenne has methods to
support these, so I'm not expecting major issues.
It's the compound data types that might be more challenging, which is
why I'm not going to support them (e.g. Money, which requires 2 fields
in the SQL object store).

I currently need to sort out seeding the SerialOid with values from
Cayenne, entities, better tests and documentation. But first I need to
document one of my paying projects, which will take a few days.
In short, it'll be nice, but don't let it hold you up.

Kevin

Crikey, that's impressive. Good job.
I'm slowly working towards v0.2.0 (site stuff etc); do we think this is
something we'll want to release in 0.2.0?
Cheers
