@nicholashcain Are you trying to add an attribute to the 'data' dataset? Or, are you trying to add an attribute to your new type? If you are trying to do the former you should do something like this:

nwb_ds = NWBDatasetSpec('a spec to add an attribute to TimeSeries.data',
                        name='data',
                        attributes=[
                            NWBAttributeSpec('gid', 'int', 'the group_id for the neuron')
                        ])

OK, I tried your suggestion, and hit a different snag:

Before I make an issue, can you confirm that I am not doing something silly? "data" was defined on line 30. Just hit me with a comment and Ill make and issue if I'm not just being clumsy. Also @ajtritt, did we come across a version of this at the hackathon?

In your script, please replace NWBDatasetSpec with NWBGroupSpec. You are creating an extension that inherits from TimeSeries which is a specification of a group, not a dataset. I gave it a quick test, and once I replace NWBDatasetSpec with NWBGroupSpec, it works.

I'll add an issue that we need to add a check for this problem when creating the spec.
