Hi all,
As part of our kickoff Metadata and Annotations WG call, we discussed formalizing the OHDSI definitions for “metadata” and “annotation” being an important step to complete before we can start creating standards and conventions.
I took a shot at writing the definitions, and we did a bit of editing during the call, but I’d like to open this up to those who couldn’t attend and to the broader community to help us refine the definitions.
Metadata is information that can be directly observed, indirectly inferred, or externally obtained about an observational data set that provides us with a more complete understanding of the patient experience being represented.
Annotations are topical notes about metadata authored by those with relevant experience or expertise that are intended to improve study design for other researchers.
Thoughts?
Thanks,
Ajit
