- Abstract
- After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.

- Abstract
- Metadata is a keystone component for a broad spectrum of applications that are emerging on the Web to help stitch together content and services and make them more visible to users. The Dublin Core Metadata Initiative (DCMI) has led the development of structured metadata to support resource discovery. This international community has, over a period of 6 years and 8 workshops, brought forth: * A core standard that enhances cross-disciplinary discovery and has been translated into 25 languages to date; * A conceptual framework that supports the modular development of auxiliary metadata components; * An open consensus building process that has brought to fruition Australian, European and North American standards with promise as a global standard for resource discovery; * An open community of hundreds of practitioners and theorists who have found a common ground of principles, procedures, core semantics, and a framework to support interoperable metadata. The 8th Dublin Core Metadata Workshop capped an active year of progress that included standardization of the 15-element core foundation and approval of an initial array of Dublin Core Qualifiers. While there is important work to be done to promote stability and increased adoption of the Dublin Core, the time has come to look beyond the core elements towards a broader metadata agenda. This report describes the new mission statement of the Dublin Core Metadata Initiative (DCMI) that supports the agenda, recapitulates the important milestones of the year 2000, outlines activities of the 8th DCMI workshop in Ottawa, and summarizes the 2001 workplan.
