Authority Records Showing Both Canonical IDs and Multiple IDs of Related Works

[AlisonBabeu]

While looking through author records I noticed an interesting if incorrect phenomenon. Take for example the record for Homer


The list of works includes not only Homer's works with canonical ID tlg0012 (Iliad, Odyssey, Epigrammata), it looks like it has also captured a number related commentary works, which in one way is awesome, but at the same time, is very confusing because they are all listed together as works by Homer, not works about Homer.

And in fact, the “Full Record” for the third work in the list illustrated above, Fragmenta (a work by Aristarchus, tlg1767.tlg001), it would appear that the TLG IDs with displayLabels “isScholiaTo” from this MODS record are in fact being captured, along with the canonical work ID tlg1767.tlg001 and its ctsurn.

I happened to check this individual MODS record in Github and it doesn’t appear that the Homer IDs have been commented out as I thought most had.

 <mods:identifier type="tlg">1767.001</mods:identifier>
                <mods:identifier displayLabel="isScholiaTo" type="tlg">0012.001</mods:identifier>
<mods:identifier displayLabel="isScholiaTo" type="tlg">0012.002</mods:identifier>

This seems to be a widespread issue, (I found the same thing with several works for Cicero, for example his list of works includes Pro Milone by Asconius, a commentary on Cicero’s For Milo
urn:cts:latinLit:phi0803.phi003.opp-lat2).

I don’t remember this happening in the last iteration or perhaps I didn’t find it last time?

@AlisonBabeu These are the documents with uncommented <mods:identifier displayLabel='isScholiaTo'> elements:

1. tlg4093.tlg007.opp-grc1.mods1.xml
2. tlg5022.tlg007.opp-grc1.mods1.xml
3. tlg5022.tlg006.opp-grc1.mods1.xml
4. tlg5022.tlg005.opp-grc1.mods1.xml
5. tlg5022.tlg004.opp-grc1.mods1.xml
6. tlg5022.tlg003.opp-grc1.mods1.xml
7. tlg5022.tlg002.opp-grc1.mods1.xml
8. tlg5022.tlg001.opp-grc1.mods1.xml
9. tlg5031.tlg002.opp-grc1.mods1.xml
10. tlg5031.tlg001.opp-grc1.mods1.xml
11. tlg1767.tlg001.opp-grc1.mods1.xml
12. tlg5019.tlg001.opp-grc1.mods1.xml
13. tlg5019.tlg002.opp-grc1.mods1.xml

The <mods:extension> element might be the place to put these relations, as some sort of RDF. (Of course, that's what the FRBRoo data would do.)

[AlisonBabeu]

It also is happening with Cicero as I mentioned before, which has an uncommented "displayLabel="isCommentaryOn" (http://174.138.78.35:8080/exist/apps/PerseusCatalog/versions.html?id=urn:cts:latinLit:phi0803.phi003.opp-lat2). I have a feeling that the current experimental interface has done this with all IDs. And you are quite right this is something that FRBRoo data will do, I guess the question for the moment, is what should I do now to fix this?

[cwulfman]

Yes -- the EUI (experimental user interface -- we need a better name now) isn't filtering ids in these situations. It could -- it would be wrong, but it could....

Here are all the display labels. Perhaps you want me to filter out all and any ids with displayLabels?

1. isScholiaTo
2. IsParaphraseOf
3. isTranslationOf
4. isCommentaryOn
5. isAdaptationOf
6. ap Galenum
7. ap Oribasius
8. ap Paulus
9. ap Aetium (lib 1-3)
10. ap Aetium (lib 5,6,8)
11. ap Aetium (lib 11)
12. ap Aetium (lib 12)
13. ap Aetium (lib. 16)
14. isParaphraseOf
15. isAttributedTo
16. isLexiconTo
17. IsTranslationOf?
18. isQuotedBy
19. isSummaryOf
20. LC Permalink
21. Corpus Iuris Civilis
22. IsAdaptationOf
23. isEpitomeOf
24. Book IV-VIII
25. FragmentIn
26. IsTranslationOf
27. Book I-III
28. Digitized SLUB edition
29. Dithyrambs

Well I believe I told you that I once suggested, with little favorable response, that we name the catalog Fred. I need to think on the ID question and filtering for a bit though.

[AlisonBabeu]

Hi @cwulfman thanks again for the list. You don't need to filter the ap Galenum to ap Aetium, in that those displayLabels aren't affecting the accuracy of the canonical IDs in question. LC Permalink also should be o.k, though ususally it is only a displayLabel on urls not identifiers. I just wish there was a good way to keep a list of filtered identifiers for an author, and split the list into works by them and works about them, but obviously that is for the next iteration with more sophisticated relationship data.
