Greetings (and please excuse the cross-postings): Recently I posted to this list (and several others) the message attached below requesting your review and comments on indexing recommendations for MARC21 records to support searches defined in the Bath and Z Texas Z39.50 Profiles. Because of the interest expressed and the comments sent to one or more of the lists, we decided to set up a new listserv to continue the discussion and feedback on the indexing recommendations. If you are interested in joining, the listserv is called "libcatindexing" and the following are the instructions for subscribing: To subscribe to the list send the following command to the E-mail address "listserv@unt.edu" SUB libcatindexing First_Name Last_Name Once subscribed, you can send messages to the list by sending them to the address "libcatindexing@unt.edu" We are very interested in the widest possible review of these draft recommendations, and would encourage your participation in this focused listserv. Thank you. Cheers, Bill William E. Moen <wemoen@unt.edu> Assistant Professor University of North Texas School of Library and Information Sciences **************************** Greetings, and excuse the cross postings of the message... The Texas Z39.50 Implementors Group (TZIG) has worked the past two years to develop specifications to improve interoperability for library catalog search and retrieval. We recognized that common Z39.50 specifications address only one part of the interoperability problem. Our Z Texas Profile (a Bath Profile compatible specification) reflects our effort on that part of the problem. The other part of the interoperability problem is a local system concern. Specifically, the differences in how systems make their bibliographic records searchable (i.e., how the local system indexes the records) have a profound impact on perceived interoperability. To address this level of interoperability, the TZIG has drafted a set of indexing recommendations, "Recommendations for Indexing MARC 21 Records to support Z Texas and Bath Profile Bibliographic Searches (Functional Area A, Levels 0 & 1)" available at: <http://www.unt.edu/wmoen/Z3950/MARC21Indexing/Z3950MARCIndexing.htm> These are not intended as the final word on what MARC 21 fields/subfields should be searchable (i.e., provide the data for indexes that support specific Bath and Z Texas Profile searches). Instead, we view the documents as containing the candidate fields/subfields that should be considered for indexing. As a community that wants to improve Z39.50 interoperability for cross-catalog searching, we should work towards consensus on a common set of indexes all systems will support to enable cross-catalog searching, and we should work towards consensus on the MARC 21 fields/subfields that would populate those indexes. We are aware that local indexing practices are a new arena to be considered for community standardization. Following the recommendations in these documents does not preclude a local system from prescribing other indexes to support local needs. These recommendations will work with the Z39.50 profile specifications in Bath and Z Texas to result in increased semantic interoperability for the limited, core set of searche defined in those profiles. We are not setting out to prescribe all local indexing practices, but instead are proposing practices that improve networked information retrieval in cross-catalog searching. We offer this draft set of recommendations for community discussion, within and outside of Texas. Specifically, we encourage you to review the documents with the following objectives in mind: 1. Identify any missing fields/subfields that should be listed to support each of the different searches. 2. Suggest a common minimum set of fields/subfields that all systems should index to support each of the different searches. 3. Assist us in understanding barriers to standardizing on a common set of indexes to enable semantic interoperability for cross-catalog searching. We expect these recommendations to evolve based on comments and suggestions during this public review period. The final result should be a Guide To Best Practices of Indexing MARC 21 Records to Support Bath Profile Searches. We appreciate your comments Please post your comments to the listserv on which you saw this posting or send them to: William E. Moen <wemoen@unt.edu> TZIG Member, Z Texas Profile Editor, Bath Profile Group Member (We are aware that some information retrieval systems manipulate database records and their fields in ways that provide access to the data without the creation of indexes. We are using the notion of "indexes" in a logical sense to talk about the problems of semantic interoperability at the local systems level.) ****************************
