BIBLIOGRAPHIC DATA FILE
The bibliographic data file contains descriptive information about transportation-related data bases. For each data base information given includes name of data base, scientific and administrative organizations responsible, person responsible for the physical aspects of the data base, data base category, location and system, descriptive abstract, timespan and coverage, availability, cost of data base, origin of raw data and the characteristics of the data elements, and the record format of the data base. The file can be accessed through the use of the data base availability system (DABAS). This system consists of an on-line retrieval capability of transportation data base descriptors and availability information. The system revolves around keywords which are selected by the user and relate to transportation topics. Two files, one containing statistical information on the data base and one providing the administrators description and objective are maintained in the system. The major output is the bibliographic data base, accessed through a system with machine-readable, on-line query capability. Information is used to produce an internal work paper as A hardcopy document. This document is designed to provide information about data bases available within the department. To insure continued effectiveness, the bibliographic data file is updated on a routine basis. Updates consist of new data base acquisition as well as internally created data bases. Input is gathered from a survey of holdings of trans-related data bases at the TRANS. Systems Center. There are plans to extend the survey to other org. Within DOT to enhance the scope of the bibliographic data file.
