At some point, it might be necessary to say that we may want to try for a different "lightweight" part of this, almost the same way that SGML
turned into XML.
Another lesson was that the people wanting to use SGML
in HL7 knew what they wanted from SGML
, but were ready to abandon SGML
when they saw that XML offered the same benefits for less work.
Not surprisingly, most discussions of SGML
in the Journal emphasized its power to address inefficiencies rather than to eliminate publications staff members.
Content Engineering can enable access to these disparate sources by presenting the content to users and applications through' content interfaces' defined via XML and SGML
DTDs and schemas.
There was SGML
, then HTML, now XML - and not too far behind is XHTML (for more on XHTML, see the accompanying glossary).
Traditionally, elements in SGML
encode structure, rather than presentation.
XML is a derivative of standard generalized markup language (SGML
), which has been a widely supported standard for 10 years.
* XML: Extended Markup Language (XML), like Hypertext Markup Language (HTML), is a subset of the Standardized General Markup Language (SGML
Markup Language (SGML
), which provides for text encoding that is not controlled by any single software developer, but which can be "validated," that is checked automatically for the internal consistency required by a computer to process it.
These improvements were made possible by transferring each record contained in a Filemaker Pro database into SGML
. These SGML
records are then indexed by an SGML
indexer, and CGI scripts interface with an SGML
search engine to provide the searching and browsing capabilities.
ACS was one of the leaders in computer typesetting of primary journals more than 20 years ago, and this format, although not following the recent SGML
(standard generalized markup language) philosophy, has been effective for their database maintenance.
