[Opensim-dev] Thoughts on adding a generic key-value storage system to OpenSim?

[Melanie]

This would go to

OpenSim.Data.XXX.XXXGenericStore.cs

It would implement an IGenericData inteface in namespace OpenSim.Data

One feature that I think would really complete the picture would be a (simple) generic data storage interface that leveraged the existing OpenSim storage framework. Most plugins I've seen (and wrote) currently tack on their own database tables, use a simple text file with a custom format, or use some other means of data storage that does not match up with the rest of OpenSim. Adding a new database table that had three columns: [context, key, value] would allow plugins to store key/value mappings (string to string) without worrying about data collisions between plugins or having to implement a custom data store every time.

If so, where would this interface go? I'm happy to write the code to implement this, I just want feedback from the dev community first to see if I'm on track.
