Notes de l'éditeur
- The National Union Catalogue (NUC) also known as the National Bibliographic Database (NBD) is a central database of catalogue records to which New Zealand libraries contribute bibliographic records and their holdings information, It supports New Zealand libraries in their acquisitions cataloguing and interlibrary loan activities.
- Updating the National Union catalogue is by traditional methods of batch load update or using Te Puna and OCLC cataloguing services. OSMOSIS is the latest addition and a sophisticated batch load system and software tool of the company TMQ Inc The MARC of Quality Inc, based in Florida. This software tool identifies changes, specifically (additions and deletions) to library holdings over time.
- No matter which method is used to update the NUC and WorldCat, changes are reflected in the holdings of WorldCat and the NZNUC through the daily exchange of records.
- Over time inaccuracies on the NUC have resulted from traditional methods of update and workflow issues. New holdings are reported from New Zealand libraries, but not necessarily changes to those holdings or holdings deletions. New Zealand llibraries needed easier ways to update their holdings on the NUC with workflow they prefer. In 2007 a business case for OSMOSIS was made. OSMOSIS showed potential as a solution for minimum effort on behalf of New Zealand libraries when contributing records to the NUC.
- The National Library and TMQ defined three high level stages for OSMOSIS processing. Preprocessing: The library exports a copy of its catalogue and FTPed to TMQ. They also receive reports back about numbers of records, quality issues and fixes are applied. OSMOSIS processing happens Post processing. The National Library receives a copy of the update file and it is loaded to the National Union Catalogue. The very first time that TMQ process a library’s file the National Library do a complete refresh of the holdings on the National Union Catalogue for that library. Thereafter each time the library file is exported the OSMOSIS process identifies changes to the holdings and the National Union Catalogue is updated with these holdings changes. Updates flow through to WorldCat with the daily exchange of records. .
- The key is that OSMOSIS takes snapshots of library holdings and compares changes over time providing files to the NUC of additions changes and deletions. All about a diff.
- Outcomes: The goal of the OSMOSIS Pilot Project - to ensure New Zealand library catalogue holdings are represented accurately on the National Union Catalogue for the 7 participating libraries was achieved. Good collaboration of TMQ, pilot libraries, and National Library. At the end of the project the recommendation was that the OSMOSIS Service be offered to those libraries already using it so that developments could be made principally in the area of cataloguing standards and to software enhancements could be made to the tool that loads updated holdings to the National Union Catalogue.
- OSMOSIS Service Enhancements 2009 So in 2009 OSMOSIS was offered as a service to those libraries that had used it during the pilot stage meanwhile developments needed in two key areas…
- The pilot highlighted the highly variable cataloguing standards used by New Zealand libraries. Issues also surfaced around the dated Te Puna recommended standards for MARC21 bibliographic and holdings records.
- Next steps Develop a viable business model: Set in place systems that are less labour intensive and develop a cost recovery platform to deliver the OSMOSIS service. This work is underway and a report will be made available to TPSAC, the Te Puna Strategic Advisory Committee. A timeline will be available in July 2010. Work toward improvements in cataloguing standards recommendations.
