Generalized Markup Language ( GML ) is a set of macros that implement intent-based (procedural) markup tags for the IBM text formatter , SCRIPT . SCRIPT/VS is the main component of IBM's Document Composition Facility (DCF). A starter set of tags in GML is provided with the DCF product.
7-415: GML was developed in 1969 and the early 1970s by Charles Goldfarb , Edward Mosher and Raymond Lorie (whose surname initials were used by Goldfarb to make up the term GML). Using GML, a document is marked up with tags that define what the text is, in terms of paragraphs , headers , lists , tables , and so forth. The document can then be automatically formatted for various devices . For example, it
14-432: A small team at IBM , developed the first markup language, called Generalized Markup Language , or GML. Goldfarb coined the term GML, an initialism for the three researchers, Charles Goldfarb, Ed Mosher and Ray Lorie, who worked on the project. In 1974, Goldfarb designed SGML and subsequently wrote the first SGML parser, ARC-SGML. SGML facilitates the sharing of machine readable documents for large projects. SGML
21-597: Is called User Interface Manager (UIM) and documented in Application Display Programming . Charles Goldfarb Charles F. Goldfarb , (born November 26, 1939) is known as the father of Standard Generalized Markup Language (SGML) and grandfather of HTML and the World Wide Web, also referred to as WWW, W3, or the Web. He co-invented the concept of markup languages . In 1969 Charles Goldfarb, leading
28-527: Is possible to format a document for a laser printer or a line ( dot matrix ) printer or for a screen by specifying a profile for the device, without changing the document itself. The Standard Generalized Markup Language (SGML), an ISO -standard technology for defining generalized markup languages for documents, is descended from GML. The Extensible Markup Language (XML) was initially a streamlined and simplified development of SGML, but has outgrown its parent in terms of worldwide acceptance and support. In
35-668: The SCRIPT/VS on the IBM PC. In 1986, he developed a PC version of ISIL called DWISIL. These products were used only internally at IBM. IBM uses GML as description language on IBM i and predecessors for objects called "panel groups". Panel groups can present just formatted help text to the user when pressing the help key (often F1), resemble the typical IBM i menus with embedded help texts, or complete application displays with input/output fields, and other TUI elements being formatted on screen according to IBM CUA Standards . The overall facility
42-399: The early 1980s, IBM developed a dedicated publishing tool called Information Structure Identification Language (ISIL) based on GML. ISIL was used to generate much of IBM documentation for the IBM PC and other products at this time. In the late 1980s, a commercial product called BookMaster was developed, based mostly on ISIL. During the early 1980s, Don Williams at IBM developed DWScript to use
49-505: Was used by the military and aerospace, and industrial publishing. Goldfarb continued working to turn SGML into the ISO 8879 standard, and served as its editor in the standardization committee. Goldfarb held a J.D. from Harvard Law School . After working at IBM 's Almaden Research Center , he was an independent consultant based in Belmont, California . This biographical article relating to
