Motivation

Coinage of the Roman Republic Online is an online version of Michael Crawford's 1974 publication Roman Republican Coinage (RRC). This is currently one of the standard references for the identification of Roman Republican coin types. CRRO reflects the typology described in RRC, but it has been updated on the basis of the British Museum’s collection management system and additional types were added. Since CRRO is a superset of RCC it is quite fair to say that a unique property may represent the two identifiers. CRRO/RCC IDs may be and are currently used by both museum curators/archaeologists or coin collectors/dealers and represent one of the main standards for the description of Roman Republican coinage. (Full disclosure: I have no relationships with the CRRO project.) Some aliases of the property may be: CRRO coin ID, CRRO ID, Roman Republican Coinage ID, RRC coin ID, RRC ID.

Discussion

Since I'm not a regular expression expert, feel free to correct the allowed values I proposed. These are some examples of valid CRRO URIs:

The regular expression may arguably be stricter, e.g., the first number is currently 1 to 3 digits long with the highest current ID being RRC 550/3c (also notice that URIs are formed using dots, while descriptive IDs are formed using a forward slash: I proposed to use the dot in the allowed values just to easily create the formatter URL, but this may be changes as well, if technically feasible, so that people may entry "550/3c", while the URL is formed using "550.3c").

Per this question I suppose a stricter regex could be: [1-9][0-9]{0,2}(\.[0-9]+[a-z])? --AlessioMela (talk) 12:31, 8 October 2017 (UTC)[reply]
