Mission Statement The mission statement for the EDS Task Group was reviewed as background for the guests. 5. Ron lambert & Keith Warriner - User Requirements Our two guests discussed how they have used data in the past and how they would like to see access to data provided in the future; they also provided some insight into just what the files we have are and how they would be used. Unless the user has a SAS or SPSS masterfile of the data (unlikely to be distributed because these will look different for each platform) the user has to create their own from the data files and the SAS or SPSS "stub" files. Because of the problem of the differences between user platforms, it is unlikely that we could provide such masterfiles ourselves. A researcher looking into a topic tends to ask about for information on where the data might be; it often happens that the exact dat are not available but inferences can be drawn from other available related data. Our guests preferred to come to a central location to check printed codebooks to see which aspects of the data tables they wish to retrieve and work with. (A good codebook will have information about the sample population, size, response rate, sample selection criteria, and other factors indicating the quality of the survey as well as information about individual questions). Codebooks can be several hundred pages long and it was suggested that it is impractical to have each user print out a personal copy. Our guests also discussed the practicality and difficulties of making and using machine readable codebooks. They agreed that searching codebooks might be useful and that access from their offices would be nice but the vocabulary shifts from survey to survey, making effective searching difficult. Serendipity is a definite factor in using codebooks and this may not change easily. There was also concern that computer neophytes are already facing a steep learning curve to retrieve and use the data, let alone retrieving and using the manuals electronically. Asked if students had access to computers that could connect to files mounted on other computers on campus (such as Watserv2 or Library) our guests responded that it was possible. Students now connect to UWInfo and WATCAT, for example. After some discussion the following model sounded feasible: The EDS would mount information on a menu structure (such as gopher) with information about titles, files, codebooks, etc... There would be pointers to programs such as the EPAS software. The files we have been calling the "stub" files (the ones to be combined with the data to become a system file) would be modified to include an NFS pointer to the data on "library.uwaterloo.ca" and made available for a user to download and use. (it is apparently possible to restrict users to UW-only with the NFS software.) Ken Warriner stressed the need for a human presence in the process. The guests were thanked for their time and thought. They were able to answer many questions from a user's prespective with background and authority few in the group have. Next Meeting: May 25, 1:30 pm LIB 428
