Feedback re first draft

Thank you for emailing link to draft specification for opportunity data.

Schemas - Data liquidity
For data transport, data just needs to get from sender to receiver. For
data interchange, the meaning of the data needs to get from sender to
receiver. To support proper interpretation by data recipients, the context
of the original data point must be available along with the data. Will the
metadata schema meet interchange use cases such as search, filtering,
transport, identification, etc?

Use of UUID (Universal Unique Identifier) rather than purely URL for
identification?

Effective Time Frame? Times may or may not be the same when data is
self-reported by the user

Matching opportunity data schema definitions with existing health schema
specifications.

Will there be any direct integrity constraints at schema level?

Capture of device information?

Use of headers re data point creation and identification / acquisition
provenance.
