Topic Maps and the Catalog

Topic Maps and Catalogues of Museums, Libraries and Archives by Liliana Melgar.
This case study is about the usage of Topic Maps for catalogues of Museums, Libraries and Archives. The first part describes two projects using Topic Maps by implementing data with the FRBR-model. The second part of the study concentrates on another two projects that uses the Topic Map paradigm to integrate several catalogues.

Topic Maps

Steve Pepper has written an article on Topic Maps for the 3rd edition of the Encyclopedia of Library and Information Sciences. "This article provides a comprehensive treatment of the core concepts, in addition to the background and current status of the standard, its relationship to traditional knowledge organization techniques, and examples of the kinds of applications for which it is being used."

Topic Maps in Libraries

Some of these people interested in applying Topic Maps in libraries created a mailing list to discuss and inform about new applications and advances in this issues.

Topic Maps

If you have any projects in a library environment that you are using or are planning to deploy that involves Topic Maps please here is a short survey. They are trying to get a general sense of what, if anything, the library community is doing with this technology.

Topic Maps in a Learning Environment

A new free tool for educators from Winston-Salem State University in North Carolina is the Topic Maps for e-Learning (TM4L).
Towards Reusable and Shareable Courseware: Topic Maps-based Digital Libraries Digital course libraries are educational Web applications that contain instructional materials to assist students' learning in a specific discipline. They play a vital role in out-of-class learning, especially in project-based and problem-based learning, as well as in lifelong learning. Digital course libraries are expected, on one side, to provide learners with powerful and intuitive search tools that allow them to efficiently access learning resources, and on another, to support instructors with powerful authoring tools for efficient creation and updating of instructional materials....

We address the problems of findability, reusability, and shareability of learning materials in digital course libraries by suggesting the use of Semantic Web technologies in creating them.... Further on, we propose that the implementation of such libraries is based on the ISO XTM standard - XML Topic Maps. Topic Maps (TM) are an emerging Semantic Web technology, that can be used as a means to organize and retrieve information in e-learning repositories in a more efficient and meaningful way.

OK Topic mpas are a kind of metadata, how would we catalog these things? Or reuse the metadta as OPI-PMH, or MODS or whatever? Will RAD make this easier?

Ontologies in Topic Maps

Ontology-Driven Knowledge Organization: Enhancing UDDI Web services in Korea Using Topic Maps by Sam Gyun Oh, Eun Chul Lee, Oknam Park, and Myongho Yi appears in Proceedings 68th Annual Meeting of the American Society for Information Science and Technology (ASIST) 42.
Effective and efficient publishing and searching for Universal Description, Discovery and Integration (UDDI) Web services is important for the success of Web services. Traditional approaches such as index, thesaurus, and classification have historically dominated information representation and organization; however, they have some limitations. Ontology-driven knowledge organization [An ontology-driven knowledge organization approach] is considered one of keys to the next generation of knowledge management applications because ontology provides structure and meaning to data. This research examines how ontology-driven knowledge organization could provide benefits to current UDDI Web services.

FRBR and Topic Maps

Alexander Sigel has put together a page looking into the Functional Requirements for Bibliographic Records, topic maps and XTM: FRBR and XTM.
  • How can FRBR used for the modelling of bibliographic relationships, using Knowledge Technologies like XTM, OWL/RDF?
  • What are Published Subjects for FRBR to be used as shared vocabularies for XTM and OWL/RDF?
Seen on the FRBR weblog.

Topic Maps

Still struggling to understand topic maps. A collection of papers on them is at techquila. Another group at ontopia.

Topic Maps

Published Subjects for practitioners of RDF, Semantic Web, Topic Maps, Ontologies and Business Vocabularies! The OASIS Published Subjects TC is holding a nocturne, Monday, November 15th, 7:30 PM - 9:00 PM, Taft Room in the Marriott Wardman Park Hotel at the start of XML 2004.

Join us to find out how the Published Subjects TC is ramping up to complete work already underway and to take on new projects relevant to your subject area. Sorry, no free drinks but lots of discussion and planning of new activities for the Published Subjects TC.

Published Subjects is an open, distributed mechanism for defining unique global identifiers. Based on URIs, the Published Subjects mechanism has two unique characteristics: It works from the bottom up, and it works for humans AND computers. For more information see Published Subjects: Introduction and Basic Requirements.

The goal of the OASIS Topic Maps Published Subjects Technical Committee is to promote Topic Maps interoperability through the use of Published Subjects. A further goal is to promote interoperability between Topic Maps and other technologies that make explicit use of abstract representations of subjects, such as the Resource Description Framework (RDF) and the Web Ontology Language (OWL).

Published Subjects as defined in this Specification provide an open, scaleable, URI-based method of identifying subjects of discourse. They cater for the needs of both humans and applications, and they provide mechanisms for ensuring confidence and trust on the part of users. Published Subjects are therefore expected to be of particular interest to publishers and users of ontologies, taxonomies, classifications, thesauri, registries, catalogues, and directories, and for applications (including agents) that capture, collate or aggregate information and knowledge.

Topic Maps

Topic Maps are something I find difficult to grasp. That, is seems, is because they are very different from our normal approach in cataloging. In cataloging (and RDF) a resource is described by using a collection of defined fields (or triples). As I begin to understand Topic Maps it seems the attributes are described and the resource description is built from different collections of topics. This could be all wrong, it is just as I get it at the moment

Here is a How to Topic Maps, Sir! provides an introduction.

Think of the topics and associations as stand-alone objects that have small bits of data attached to them. For those who are in the deep end of object-oriented programming may think "Hey, wait a minute! This is nothing but a tree structure with various properties attached to the nodes." And you would be absolutely correct in that. That is what it is, with certain names and labels attached in clever ways. No magic. No smoke and mirrors. Just a nice little data model with some rather clever ideas and rules through it. Welcome to Topic Maps.

Topic Maps

The Library of Congress presents the Luminary Lecture, Topic Maps: Subject-Based Access. The video of the lecture will be available live on Wednesday, October 15 from 10:00 am -12:00 noon EST in RealPlayer format. To view it, you must have Real Player installed and at least a 28 Kbps connection.
Join Michel Biezunski and Steven R. Newcomb, the creators and pioneers of the Topic Maps Paradigm, which they developed in 1992. Newcomb will address the conceptual foundations of the paradigm concerned with creating and maintaining subject-based indexes that amalgamate other subject-based indexes. He will then answer the central question of the Topic Maps Reference Model: "How can a master index be made from indexes that were never intended to be merged with others?" Biezunski will then discuss the possibility of amalgamating knowledge resources (including finding tools) expressed in accordance with diverse interchange standards, by creating a new layer where semantic integration has a broader range of application. He will also review his experiences in applying the paradigm and its effects on the ongoing development, using the Internal Revenue Service application as a case study.

RDF and Topic Maps

Taking RDF and Topic Maps seriously - what happens when you drink the Kool Aid by Kent Fitch is an older piece (but new to me), 2002, but worth a look.
A great deal of attention has been focussed on the concept of the "Semantic Web". One of the core ideas behind the Semantic Web is the creation of machine-processable relationships between resource identifiers (URI's). Two often discussed ways of representing those relationships are RDF and Topic Maps.

This paper describes how the concepts and goals of Resource Description Framework (RDF) and Topic Maps influenced the design of the Australian Literature Gateway (AustLit) project.

There is some connection to FRBR as well.
AustLit is a bibliographic and biographic system that represents its core application data using a new model from the International Federation of Library Associations (IFLA) known as the Functional Requirements for Bibliographic Record (FRBR) model.
