Subject headings (650) in Sources and Secondary Literature should be split

[jenniferward]

Currently, all terms entered into the field 650$a, whether in a Source record or in the Secondary Literature, end up in one index: https://muscat.rism.info/admin/standard_terms

This is problematic for the users because they see terms from both areas when cataloging a source, which leads to confusion and potentially incorrect application of terms to sources. Here is an example. Only "Finales" should show up in Sources. The rest are used only in Secondary Literature. It is also harder for catalogers to search the index because they see many terms that are irrelevant to source cataloging.

Please split this area so that the 650s used in Sources are in one index, and the 650s used in Secondary Literature are in a different index.

Then, please ensure that the autocomplete in the 650 in Sources only shows terms from the Sources index, and the 650 in Secondary Literature only pulls terms from that area.

This could be a very welcome improvement. I keep hearing comments that the subject headings are not easy to deal with, so any development that would meaningfully restrict the options should improve the user experience (and would at the same time make it easier for the editors to "tidy up the room" after the catalogers).

My question, though, is how this would then look like in Muscat: In the drop-down list under "Authorities" we would also start to see two different lists of Subject headings?

I think on the Muscat side it is not too difficult to implement, but how do we choose what goes in Sources and what in Std Terms?

Maybe by introducing function relators in subject headings for musical genres (650 in sources) and keywords used in secondary literature.

Can you just do a pull of all 650s that appear in Sources and all that appear in Lit? There is probably very little overlap, and if there is, I would keep it in Sources and then copy it over to Lit when needed. (If that answers your question, @xhero.)
