2011

The meta-data used with graphics produced before January 2011 (i.e. before GN27310) was slightly different from that used today

In particular please note:
IPTC Scene was given as "wrap" (now left blank)
Intellectual Genre given as : “News, Sport, Business, Science & Technology, Entertainment” (now given as “Graphic”)
Keywords were delimited by full stops (rather than comma or semi-colon). The Description was not included (whereas it is now)
IPTC Subject code was given as “MAP;GRAPHIC” rather than the constrained list of 8 digit numbers used today in Subject Codes.
