Incorrect use of EPSG code as 'EPSG4326' or '4326' #31

Closed isotc211 closed 3 years ago

isotc211 commented 3 years ago

Justification: Incorrect use of EPSG code as 'EPSG:4326' in ISO 19128, and as 'EPSG4326' or '4326' in ISO/TS 19139. Proposal: Correct use was 'EPSG::4326', as specified in OGC 6-023r1 Definition identifier URNs in OGC namespace, which was superseded by OGC 07-092r3 for the URN form, which has itself been superseded by OGC 09-048r3 Name type specification - definitions - part 1 - basic name for the http URI form which as of June 2010 became the preferred form for OGC identifiers.

Hence, identifiers for EPSG definitions are http://www.opengis.net/def/{type}/EPSG/0/{code} where {type} is crs, cs, datum, etc.
