jens 06:15, 11 March 2013 (UTC) I don't know whether a special format is needed. Thus I used String in the draft.
I thought about the definition and it seems that was the simplest solution I could get.

ISO 19135 ("Geographic information - Procedures for item registration") defines "identifier" as a "linguistically independent sequence of characters capable of uniquely and permanently identifying that with which it is associated".

Definition: A language-independent sequence of characters capable of uniquely and permanently identifying that with which it is associated, and defined according to a specified scheme.
Remarks: Needs to pinpoint a particular source of information, such as a publication or chart. The scheme may be either arbitrary or according to some encoding system.
Examples: "978-3-86987-298-8" (ISBN for BSH Sailing directions volume Nr. 2001, 2012 edition, title "Ostsee-Handbuch, Östlicher Teil"); "Seekarten nr. 62", or "62" (BSH number for the 2011 BSH paper chart covering the Kattegat).
