extending SGML to accommodate database functions: A methodological overview

摘要

A method for augmenting an SGML document repository with database functionality is presented. SGML (ISO 8879, 1986) has been widely accepted as a standard lan- guage for writing text with added structural information that gives the text greater applicability. Recently there has been a trend to use this structural information as meta-data in databases. The complex structure of docu- ments, however, makes it difficult to directly map the structural information in documents to database struc- tures.
