[jeff-hernandez]

The label times object was refactored by:

• isolating deserialization functions and label descriptions into separate files
• improving checks and inference for target name and type
• simplifying docstring tests for bin transform

I like the changes. Do we want to add a warning based on if the schema version is older / newer than expected?

[jeff-hernandez]

Yes, I think that's a good idea @rwedge. We can add a warning as a result from different schema versions. Perhaps it would be easier to do this in a separate PR.

Sounds good, can you make an issue for it?

[jeff-hernandez]

Yes, tracking this issue at #145.

[rwedge]

Looks good
