L-identifiers added

From the 3DMet website [1], I understand that with the release of version 3.0 (2018-03-30) L-identifiers are added, like L00520 guaiazulene (Q3026266): 3DMet:L00520. I suggest format as a regular expression (P1793) for this property be changed into: [BL]\d{5}. - DePiep (talk) 16:27, 31 May 2018 (UTC)
