The Codex is not a separate data store, it is more like a federated search -- so data is not "imported" into the Codex Search, but it is made available to the Codex Search from the underlying storage modules (right now that's inventory and the EBSCO knowledge base).
Describe the intended use of the app or part of FOLIO. This may be short or long, depending. You could describe things like common workflows that take place in the app; configuration options; whether an app has specific integrations with outside vendors.
Reporting ??? <not relevant>
Describe available in-app reports, including parameters for the reports, and associated permissions.
If there are developed LDP reports/queries for this app / area of FOLIO, describe those reports as well.
List any fields that may not be available in the LDP (e.g., for privacy reasons.)
