On providing client support for machine readable data files

Abstract

209 With the increased power of the microcomputer, there is growing use made of Machine Readable Data Files (MRDFs) for data analysis by data users. Data providers use distribution systems ranging from 9-track tape, diskettes, CD-ROM, transmission of data via on-line networks or access to data from on-line systems. As the quantity and complexity of MRDFs increases, and as the medium for access becomes computer-to-computer linkage, there is a urgent need to improve the quality of both the supporting documentation and the software that is included with these files. We concentrate in this paper on the issues of how and what meta-information should be provided to users of public use microdata MRDFs. As the marketing and sale of such data become increasingly important to statistical agencies, it is essential to view these issues from the external client's perspec­ tive. Indeed, the meta-information can be seen to play an indispensable role in advertising the availability of the product and in supporting the client's use of the product.
