> * Support =, >, < etc queries on Bib-1 lastModifiedTime We don't do lastModifiedTime as BIB1, but have the equivalent in unix ctime format in Explain. Equally Explain--/Zeerex would be of use as well as it has the equivalent. This is on a per database level of course, which means you'd not be able to download just changed or new records, but only know if it had changed since you last checked. > Basically I was wondering if it was possible to efficiently "harvest" > a Z39.50 database. The best I can think of is using last-modified-time. We harvest keywords via scan (as I talked about very briefly at the ZIG) and check Explain's lastUpdate to see if we should schedule a new harvesting. HTH, Rob -- ,'/:.
