Session 1

Directories Workshop

Chair: Terry Fisher (CCRS)

Mon, 6 Nov 1995, 10:45 am to 5:30 pm

AGENDA

This session of the Science Information Systems Interoperability Conference (SISIC) focuses on directories to data. An initial search for data sets often begins with a broad-based query at the directory level. The intent of data set descriptions provided at this level is to aid the researcher in determining the value of individual data sets to the envisioned research effort. Although there is general agreement in the community that researchers should be able to perform searches of multiple databases with one query, there are several different models being implemented to perform such searches. In that the data model chosen has a significant impact on population efforts associated with data directories, it is instructive for those building, populating, and using data systems to be aware of the various approaches being considered to accomplish the single query objective.

Presently, directory level information is rarely coupled with more detailed metadata and actual data. Fostering closer ties between the metadata and data will assist in more rapid and comprehensive population efforts. Furthermore, the rapid increase in the distribution (and description) of data sets on the Web points to a need for automated population efforts, regardless of the directory model chosen. In light of this, the conference will begin with a directory session designed to stimulate discussion in the areas of online data directory models or software tools designed to locate data sets described on the Web. Submissions addressing either topic are solicited for this session.
