Meet oclcBot. He was written by Bruce Washburn at OCLC Research to help connect Open Library records to Worldcat.org. He’s just finished updating almost 4 million Open Library editions with links! No metadata exchange at all, except these identifiers. Tiny, but powerful, because that lets systems that “speak OCLC” communicate directly with Open Library without knowing any Open Library IDs. As Anand mentioned in his recent post about Coverstore Improvements, we’ve also made the system for displaying covers externally using other types of identifiers more efficient.
