We’re working on implementing OMOP here. Clinical tables are well underway, but I have some questions regarding the metadata table. Namely, what specifically is expected to be in the table? The documentation at
https://ohdsi.github.io/CommonDataModel/cdm54.html#metadata
is extremely vague. What, if anything, is required to exist. What is suggested? Is it simply for documenting table and field information as some of the information in the github issue page indicates? If we have all that documented in our mapping documents, is it not needed?
Welcome to OHDSI, @David_Nance!
The Metadata table is not a required table. I agree, the specifications are very vague. I’ve created an issue in the CDM GitHub to update these.
I don’t know anyone who uses this table. And I haven’t seen an OHDSI study which requires this table. I’m interested to hear from others if and how they use it.

EHDEN has a very good set of metadata for each dataset. It would be great to see their framework adopted by whole community.
Few years back, we had initiative around metadata and since then there was nice formalization of many of those. Time to revisit it and specify some well accepted metadata.
