Dear Maria
Thanks you. I've read your (very useful) London presentation: http://www.slideshare.net/MariaTheodoridou/london-meetup2014-mappingchi2cidoccrm and I plan to take advantage of the mapping: http://www.ics.forth.gr/isl/3M But I'm tempted to treat the coins as exemplars of an "issue", i.e. <F5_Item> <crm:R7_is_example_of> <crm:F3_Manifestation_Product_Type> IMHO, a thing like: http://numismatics.org/ocre/id/ric.1(2).cl.31 is a F3, mutatis mutandis. When you did your mapping did you considered something like this ? And which were the arguments against ? Best, Dan
