I have worked at OCLC since 1985 and in the Office of Research since 1996. Prior to transferring to the Office of Research I worked in OCLC's Development Division as part of the team that designed, implemented and supported the Prism Terminal Interface, known today as the WorldCat Cataloging Service. One of last projects I was assigned to before transferring to the Office of Research was the creation of a prototype for browsing the Library of Congress Classification using a Web browser.
Since transferring to the Office of Research I have contributed to the publication of the second edition of "Subject Headings for Children" and the first edition of "People, Places & Things". The Subject Headings for Children publication provides a list of over 20,000 popular Library of Congress Subject Headings from the Annotated Card Program and pairs them with corresponding Abridged Edition 13 Dewey Decimal Classification® numbers. The People, Places & Things publication provides a list of over 50,000 popular Library of Congress Subject Headings and pairs them with corresponding Edition 21 Dewey Decimal Classification® numbers. Both of these projects explored semi-automated techniques for mapping terminology.
Besides the publications, mentioned above, I have been involved with other projects that have used the Dewey Decimal Classification® and/or the Library of Congress Subject Headings. One project involved the development of a prototype for viewing the Abridged Edition 13 Dewey Decimal Classification® from a CDROM using a Web browser and was demonstrated at the 2000 Midwinter ALA in San Antonio, Texas. Many of the techniques for manipulating and converting the classification data were reused when I was involved with the WebDewey in CORC project, known today as WebDewey in Connexion®. During this time I created an XML representation of the Dewey Decimal Classification® for use by licensees and translators.
Additionally, I was fortunate to participate in a meeting at the Library of Congress that finalized the MARC-XML standard.
My research interests include classification schemes (enumerated, faceted and hierarchical), synonym rings, subject heading systems, thesauri, Web Services and RSS. From a technological aspect, most of my projects are accomplished with XSLT, Perl and Microsoft tools such as Office, SQL Server, ASP.NET and VB.NET. But I have been known, on occasion, to program in other languages such as Forth and Java.
