The discussion on P2190 suggests moving to numeric format for C-Span Person IDs from the string format, currently this uses the string IDs and will add unwanted strings to Wikidata that are not reliable for links as redirects are not being added, but a query to the URL may return the numeric ID in the response URL if the string still correctly resolves. - Property talk:P2190. The templates have been notified, numeric pairs uploaded to Wikidata, and bot request to root out the string IDs in EN Wiki. I tried to deactivate this catalog to prevent further string inserts, but the save doesn't seem to take effect. ~~~~
