SGML Document Structuring: Implementing Document Analysis 
SGML (ISO 8879) provides organizations a standard for structuring and managing electronic information independent of software and hardware restrictions. Its premise is that all documents have a logical structure that can be represented with symbols. Using these symbols, SGML identifies a document’s elements and their interrelation slips. SGML separates format from content, allowing masses of information to be logically stored and easily retrieved. Data from one document marked with SGML tags can be used to create everything from brochures to reference manuals. This workshop emphasizes SGML document analysis and its impact on technical communicators.
