Options for Organizing Electronic Resources: The Coexistence of Metadata

Abstract

With the rapid growth in the number of electronic resources available via the Internet, a variety of methods have been developed to organize and access these objects. Librarians, scholars and computing engineers each have applied their own techniques to the process. Catalogers envision a "super-catalog"; scholars spawn encoded texts; computer engineers design robot-generated indexes. Each method has its strengths and its weaknesses, and each group casts a wary eye upon competing systems. In fact, it is unrealistic to believe that the organizational system of any one group will be adopted by all players in the electronic arena. While general principles of organization should apply to all approaches, cataloging the Internet is inherently different from cataloging a library. Libraries are systematically developing collections of primarily fixed objects usually under the control of one institution or agency. The Internet is more analogous to the ubiquitous ebb and flow of information and services appearing throughout society. The structure and content are not systematically developed and stable; there is no single user group or purpose for the Internet; and there is no single controlling agency. Thus, there is no one community, be it scholars, computing engineers or librarians, that is clearly vested with authority to decide upon the best means to bring control over this electronic chaos. Considering that the Internet has always been a decentralized initiative, it is not surprising that the efforts to organize it have been similarly independent and uncoordinated. Analogous to a loosely coupled communication system, each community working to organize the Internet is somewhat responsive but essentially autonomous. It is likely that each of these autonomous groups will continue to develop methods for description and access that best meet their own perceived needs. At best, cooperative efforts may result in some common understanding of a core set of descriptive data; but it is unlikely that the application, structure and use of that data will be identical within all communities. It is important, therefore, that each group recognize the contributions of the others and that together they provide bibliographic control methods that can be layered, interchanged and translated within a broad but loosely coupled system of organization. In this way, each community can continue to develop methods compatible with its own users' needs, while taking advantage of data and systems created by other groups. Remote electronic resources have engendered discussion of the catalog's scope and functions, the concept of a collection and the appropriateness of including bibliographic surrogates for remote resources in a local catalog. Traditionally, library catalogs have provided macro level access to whole items in the collection, relying on other bibliographic tools, such as indexes and bibliographies, to provide micro level access to bodies of literature and parts of items. One criticism of this distributed bibliographic system is its failure to provide access to everything in the library collection through one totally integrated catalog. More sophisticated computer technology offers new possibilities for correcting this problem. Electronic indexes and databases mounted on the local computer provide, if not a truly integrated catalog, a reasonably integrated interface that allows access to several bibliographic tools from one terminal. Work continues to develop more sophisticated layering systems that offer searchers the convenience of accessing simultaneously the OPAC and several other databases with a single search query. While providing the illusion of searching a single database, these systems could use both front-end interfaces that convert differing search commands into one common command language and multi-language thesauri that translate terms used by one database into those used in another. These techniques of layering, exchanging and translating
