Last Saturday I passed the time while waiting in line at the DMV by reading the recently released Study of the North American MARC Records Marketplace. The analysis of the survey results seem to focus on the role of the Library of Congress in the marketplace, which is understandable given that LC funded the report. [...]

Terry’s analysis of the proposed changes to OCLC’s record policy is essential reading. I’m really concerned that these 996 fields will slip somewhat unnoticed into data that I use.

pymarc PEP-8 cleanup

Thursday, February 28, 2008

Recently there was a bit of interesting news around a MARBI Discussion Paper 2008-DP04 regarding semweb technologies at LC.

Related to this work are RDF/OWL representations and models for MODS and MARC, which we are also developing. Several representations of MODS in RDF/OWL, such as the one from the SIMILE project, have been made [...]
