Properties used in library science for Subject

I've added a few new "properties for this type", aka, "things one could say
about" for *Subject.*  If you click on the below Wikidata URL you will see
the new statements for "P1963 properties for this type
<https://www.wikidata.org/wiki/Property:P1963>"

Wikidata item:  *s**ubject*
URL:  *https://www.wikidata.org/wiki/Q12310021
<https://www.wikidata.org/wiki/Q12310021>*

*- related category <https://www.wikidata.org/wiki/Property:P7084>*
*- broader concept <https://www.wikidata.org/wiki/Property:P4900>*
*- native label <https://www.wikidata.org/wiki/Property:P1705>  (which
seems quite useful?  I've seen this in library catalogs before)*
*- label in sign language <https://www.wikidata.org/wiki/Property:P2919>
(also quite useful, I guess?)*

Questions, concerns?
