There are various syntaxes and variants of patterns commonly known as regular expression (Q185612). Currently there is no way to express on Wikidata which syntax/variant applies to a particular pattern stated as a value to properties such as format as a regular expression (P1793) and file format identification pattern (P4152).

Maybe "criterion used" or "as".

Comment The definition of programming language (Q9143) is general enough that it could potentially allow programmed in (P277) to be used for regular expression (Q185612). The question is whether a distinct/separate property justified, or could an existing more generic property be reused for this purpose. Pixeldomain (talk) 06:05, 7 August 2017 (UTC)[reply]
Support. I support the creation of this property. YULdigitalpreservation (talk) 16:54, 9 August 2017 (UTC)[reply]
