The Knot Atlas is a curated, closed-editor-access wiki that is an authoritative source of information on mathematical knots and links, for which both Wikipedia and Wikidata have a number of entries. It is maintained by knot theorists w:Dror Bar-Natan and Scott Morrison. Providing links to the Knot Atlas will provide Wikidata users access to a wide range of information about these entities that goes far beyond the range of information currently planned to be stored on Wikidata, as well as providing a source of potential data for those entries. If this property is created, I can fill in values for existing entries using my bot.

Note that this is not a redundant property: sometimes, it's derived from the Alexander-Briggs name, sometimes it's derived from the D-T name (but with a K at the start), sometimes it's something else entirely; and it's a string, not LaTeX-formatted mathematical text. -- The Anome (talk) 13:06, 25 June 2020 (UTC)

Thanks! I should be able to fill this information in in a couple of weeks, after I've done the other knot properties. -- The Anome (talk) 13:16, 14 July 2020 (UTC)
