Berlin Joins OCRE Project

We are kicking off the new year with a major breakthrough in the Online Coins of the Roman Empire project. Yesterday, I received a data dump of LIDO/XML of Roman imperial coins from the Berlin M├╝nzkabinett, for which I wrote two PHP scripts: the first to create a concordance between their reference field and coin type URIs in OCRE, and the second to iterate through their dump to create RDF that I just ingested into Nomisma.org's SPARQL endpoint. Nearly all of Berlin's coins are photographed, and all contain axes, weights, and diameters which are available for metrical analysis through OCRE visualization interface (http://numismatics.org/ocre/visualize).

In the week before the holiday, we completed RIC Volume IV, covering all Roman emperors through Uranius Antoninus (A.D. 254). There are now more than 21,000 coin types available in OCRE, with physical specimens from the British Museum and Berlin now linked in through Uranius. We are waiting on some updates from Mantis in order to link in ANS coins for Trebonianus Gallus, Trajan Decius, and a few others. We also expect a batch of photographs for several thousand coins in the coming weeks.

We should be moving into RIC V by next month.

edit (12 Jan. 2015):

All of Berlin's coins in OCRE come with photographs, but the current number (3,620) is not representative of all of Berlin's Roman imperial coins. Only those which have been photographed are published to the database online.
