??! Umm, I take it you don't mean HyperText Markup Language
, which could not have preceded SGML... or is my understanding
way off here?
Poor editing on my part - humblest apologies. It should have been GML
also know as DCF GML (Document Compositon Facilty GML - an IBM standard
of the early 80s).
There may be a danger here of mixing "levels", so maybe I'd better
clarify one thing for the sake of it:
TIPSTER is an alternative technology to *SGML*, as a means of
"marking up" documents. The TIPSTER architecture itself (at
least as far as my understanding goes) does not define any tags etc,
in the same way that SGML does now. It's a formalism.
I agree about the issue of mixing "levels" and I'm not sure to call
"TIPSTER...an alternative technology to *SGML*" gets over the problem,
although I think I understand the spirit of what you say and would agree
with the direction of separation. Would it make sense to talk about
TIPSTER having a different implementation of SGML than other
(proprietary) MARKUP software in that it uses virtual markup rather than
in-line markup? This leaves SGML to be a standard and not a program to
which TIPSTER and many other pieces of software may or may not conform
in that they can parse a piece of text that comforms to the standard. I
acknowledge that this might deny the implicit nature of SGML, that it
expects the markup to be in-line and not virtual, but at least it could
clarify discussions as to whether they are about the standard of SGML as
against SGML-aware programs.
*As far as I'm aware*, there are a number of "tags" which have been
defined by the TIPSTER community, to meet their own needs (primarily
those of the "defence" agencies (or "the spooks" as they're sometimes
known! ;-) . These may be very different from the needs of the
community that developed the TEI tagset! I don't believe there is any
plan to replicate the effort of the TEI, there is simply no utility in
This clarifies my uncertainty as to whether TIPSTER is a program or a
standard - its a program.
One of the projects underway at Sheffield is aimed at creating a
bridge between the SGML and TIPSTER formalisms -- I wondered if anyone
else (in the TEI community) had either tried this, or had any
interest in it. At an intuitive level I can't see any reason why the
TEI *tagset* can't simply be used in a TIPSTER environment.. . it just
wouldn't be in SGML.
I don't see any reason why TIPSTER can't be a fully conformant SGML
parser and still have more of its own things that its authors feel are
appropriate. I think this is where thinking of SGML as a standard and
TIPSTER as a program is a useful distinction.
