76 ORGANIZACIJA ZNANJA 2014, LETN. 19, ZV. 2 Authority Indexes • Cartographic Data (cm:). • Entity Attributes (en:). • Generation Agency index (ga=). • Generation Process index (gp: and gp=). • ISSN Link (ik:). • Relationship (rx:). Clearly, not all of them are directly related to RDA, but several (including the Bibliographic "Description Con- ventions" index, the Authority "Relationship" index, and both "Entity Attributes" indexes) are. Generally, new Bibliographic indexes get gradually populated as records are added to WorldCat or are replaced. The "Entity Attributes" (en:) indexes in both the Bibliog- raphic and Authority files give access to all of the relevant new RDA-related fields (such as 34X, 37X, and 38X) and some previously-defined fields that seemed appropriate. In Authorities, especially, using this index in conjunction with, say, a proper name, could narrow down a search of common names to only those with specific attributes that could be found in one of these fields (Associated Place, Field of Activity, Occupation, etc.). Just as important as the creation of new indexes is the addition of new elements to existing indexes. Among the most obvious and potentially important is the addition of the new Bibliographic field 264 ("Production, Publication, Distribution, Manufacture, and Copyright Notice"), sub- field $a to the "Publisher Location" (pl:) index, subfield $b to the "Publisher" (pb: and pb=) index, and both subfields to the "Keyword" (kw:) index. If my count is correct, we have added dozens of new and/or existing fields and/or subfields to at least twenty existing Bibliographic indexes and at least five existing Authority indexes since 2008. Perhaps most significantly, we have worked many of the appropriate RDA entity attributes fields into our "Material Type" (mt: and mt=) Bibliographic indexes. All of those are documented in the "Format/Document Type Valu- es and Codes", "Material Type Names and Codes" and "RDA Terms and Codes" sections of the document "Se- arching WorldCat Indexes" (http://www.oclc.org/support/ help/searchingworldcatindexes/Default.htm ). The Connexion browser was most recently updated in May 2012. A full list of recent Connexion browser enhan- cements is available at http://www.oclc.org/connexion/ interface/browser/recent.en.html . The Connexion client Version 2.50 was released in No- vember 2013. Connexion client Version 2.51 was released on April 16, 2014. This most recent release addresses an export problem tied to eleven specific MARC-8 charac- ters and affects only libraries that export with the MARC- 8 character encoding selected. This issue is only with the Windows-based Connexion client; it does not affect the Web-based Connexion browser interface. OCLC will sup- port both 2.50 and 2.51 for the foreseeable future. A full list of recent Connexion client enhancements is available at http://www.oclc.org/connexion/interface/client/recent. en.html. Beginning with the release of Connexion client Version 2.40 in March 2012 and the updating of the Connexion browser in May 2012, several RDA-related improvements have been made. For RDAworkforms, you may set an option in the client (Tools > Options > RDA tab) or brow- ser (General tab > Admin > Preferences) to use RDA ver- sions of the existing AACR2 workforms to create records. You may set the options separately for bibliographic and/ or authority workforms. Existing AACR2 workforms open by default when you create new records unless you set the RDAworkform option(s). You may additionally select the new RDAToolkit IP authentication option to link to the RDAToolkit without having to re-enter your RDAToolkit username and password in Connexion. Looking forward to the full implementation of OCLC's GLIMIR Project (Global Library Manifestation Identifier) (Gatenby, 2012), both Connexion interfaces now allow you to set an option to show search results in GLIMIR clusters of WorldCat bibliographic records that have dif- ferent languages of cataloging for the same work (called "parallel" records). For each cluster, GLIMIR search results will show the number of records that your library holds, the total number of holdings, and the total number of records. GLIMIR clusters will make it easier to iden- tify and select the exact record you need for cataloging. You will also be able to show the GLIMIR cluster for any displayed bibliographic record by using a new menu item Cataloging > Show > All GLIMIR Cluster Records. At the present time, OCLC strongly urges users not to select the GLIMIR option because many records in WorldCat do not yet contain GLIMIR information. OCLC will an- nounce when this option is available for use. Behind the scenes and in conjunction with the many indexing changes that have already been touched upon, corresponding fine-tuning of all WorldCat matching is ongoing, incorporating RDA elements into the existing algorithms. This applies not only to all indexing and sear- ching, but also to all batchloading, to Duplicate Detection and Resolution (DDR), and to GLIMIR. As new RDA elements, fields, subfields, and codes are implemented, we also have to readjust existing validation rules so that data relationships continue to make sense, to the extent that they can.
