The LSST Baseline Schema that is linked to from the Schema browser is not used in any database, does not get updated to reflect our current file or database data model, and will become more and more out of date in the future because of this. I propose that we remove this schema from the online browser, but keep the sdm_schemas/yml/baseline.yaml file around for our own internal reference (and note in it that it is purely for historical reference). Referring to this schema on the browser page as 'the “goal” of the Rubin Observatory construction project' is misleading, since we've already moved well past it and haven't updated it.
A related question is what to do about LDM-153 and the DPDD: if we are not keeping our "baseline" schema up to date with our actual production data model, what purpose do those documents serve? Certainly, we should not be referring people to them to answer questions about what the data release/alert schemas will look like. The online schema browser is a big step forward in letting people know what we are actually producing.
In some sense, removing the baseline schema from the online browser shouldn't need an RFC, because it won't actually impact any users, developers, CI process, or code. I'm filing this because "what do we do about the baseline schema?" came up while ebellm and I were working on revising the APDB schema, and the consensus seemed to be "we do nothing with it".
