Sorry, Craig, but there's nothing to suggest that MIF has any basis in SGML, either.
MIF existed in FrameMaker from version 1.0 in 1986, which was the same year that SGML formally came into existence. Frame Technologies did not offer a product that supported SGML until they released FrameBuilder in 1992 in the FrameMaker 3.0 era. There is a fundamental difference in philosophy and purpose between MIF and SGML. The whole idea behind SGML was to define a way in which information could the marked up to self-identify the *semantic* purpose of the information independently of the presentational aspects (formatting) of a particular document. As tools for SGML were developed, the philosophy was that the presentation should be driven by the semantic purpose of each information element in its current context. MIF, on the other hand, is focused almost entirely on the *presentational* aspects of the information that is contained in a document. This is entirely appropriate because the language is used within the environment of a document processing software application. There is also a fundamental difference in the way the markup is structured. In SGML (and XML and HTML) only the tag names and attributes are contained within pairs of angle brackets. The content is contained between pairs of bracket-delimited tags (although the end tag may be assumed in some cases in HTML and SGML). Parsing out everything that is contained in brackets yields the raw, untagged text. In MIF, *everything* is contained within the angle brackets as <name value> tuples. The only thing that exists outside angle brackets are commentary strings that identify MIF structures. The document content is actually contained in delimited strings within a <String ` '> element that is wrapped up in a bunch of nested formatting elements. For example, the following MIF snippet represents a single cell of a table that contains a single text character (I for "input") in a String element that is nested 4 levels deep inside a Cell element, which is, in turn, nested inside Row, TblBody, and Tbl elements: <Cell <CellContent <Notes > # end of Notes <Para <Unique 1022301> <PgfTag `CellBodyCenter'> <ParaLine <String `I'> > # end of ParaLine > # end of Para > # end of CellContent > # end of Cell If a text editor were to provide really useful on-screen highlighting, it would have the ability to highlight all the lines that are within a matching pair of brackets, such as the 11 lines that constitute the CellContent element or the 13 lines of the Cell element in the example. Just highlighting the element or property name that follows the left angle bracket may look nice, but really isn't particularly helpful IMO. It's really unfortunate that people jump to the conclusion that any markup language that uses angle brackets must be based on XML or HTML or SGML. There are only a small number of characters on a standard keyboard that are suitable for use as delimiters in a markup language and many different markup languages *independently* chose angle brackets as the best option. In reality, we should all be thankful that the authors of these markup languages chose something relatively user-friendly like angle brackets rather than retaining the ancestral form of markup use in IBM's Generalized Markup Language (GML) which looked something like this: :h1.Chapter 1: Introduction :p.GML supported hierarchical containers, such as :ol :li.Ordered lists (like this one), :li.Unordered lists, and :li.Definition lists :eol. as well as simple structures. :p.Markup minimization (later generalized and formalized in SGML), allowed the end-tags to be omitted for the "h1" and "p" elements.Notice that only the ordered list structure (:ol) has an explicit end delimiter (:eol), whichc makes it really hard for a human reader to figure out wheretheheck you are. > From: craig...@hotmail.com > To: docu...@hotmail.com; shmue...@gmail.com; firstname.lastname@example.org > Subject: RE: What free Windows text editor should I use to look at MIF files? > Date: Mon, 6 Oct 2014 07:32:26 -0500 > > > > Perhaps > a project should be started to work on defining a MIF highlighter for > NotePad++, since one can create a User Defined highlighter. > > > > > > Also, since FM SGML was around earlier than FMs XML capabilities, would > it be accurate to say that MIF is an SGML based tagging implementation? > (I expect even FMs SGML implementation came later but broader SGML > definitions were certainly in use earlier).
