The Association for Computing Machinery (ACM) has contracted with OCLC to provide an end-to-end electronic publishing system for their journal publications. This report focuses on the article conversion component, which converts accepted articles from the original format used by the author to Standard Generalized Markup Language (SGML), based on ACM's SGML Document Type Definition (DTD). The conversion component can work with documents in several word-processing and text-editing formats, including WordPerfect, MS Word, Framemaker, and LaTex, that originate on a variety of platforms, including DOS/Windows, Macintosh, OS/2, and Unix. The key transformations in the process are: (1) from the native format to Rich Text Format (RTF), and (2) from RTF to SGML. Exoterica Corporation's OMNIMARK programming language is used for the second step, while each word processor creates the RTF files.
