                       INFORMATION ABOUT SGML SIGHYPER
                         (THE HYTIME INTEREST GROUP)





THE SGML [1] USERS' GROUP SPECIAL INTEREST GROUP ON HYPERTEXT  AND  MULTIMEDIA
(SGML  SIGHYPER)  is  different from all other groups whose focus is hypertext
and multimedia theory, technology, and creativity.  The sole interest of  SGML
SIGhyper  is  the  promulgation  of  information  about  the  ISO/IEC "HyTime"
Hypermedia/Time-based Structuring  Language  (ISO/IEC  International  Standard
10744  [2]),  as  a worldwide standard technical framework for integrated open
hypermedia, and in the applications of HyTime, including  the  ISO/IEC  "SMDL"
Standard  Music  Description Language (ISO/IEC Committee Draft 10743). We hope
that the publishing, documentation, entertainment, education, and  information
processing  industries  will evaluate HyTime as an appropriate standard toward
which they all can migrate in an orderly and profitable fashion. The intent is
not  to inhibit competition; quite the contrary, it is to help to create a new
arena for competition, and to help to train and equip the  players.  Now  that
HyTime  has become an officail international standard, we expect that SIGhyper
will serve as both a matchmaker and an information warehouse for customers and
vendors in the hyper/multimedia market.

SGML SIGhyper has been created to provide a way for those who want a  flexible
and  open  technical  framework for hypermedia publishing to contribute to the
process of creating that framework.  Your membership  in  SGML  SIGhyper  will
connect  you  as  directly  as possible with the ISO [3] process, so that your
requirements for integrated open hypermedia can be known publicly and  met  in
the  course  of  a public process, and so that you will be informed about per-
tinent developments regarding technologies relevant to the  creation,  mainte-
nance,  and  processing  of  hypermedia  documents  represented in SGML.  SGML
SIGhyper's parent organization is the international  SGML  Users'  Group,  [4]
which  is  privileged  to send limited delegations to ISO meetings where SGML-
based standards such as HyTime are developed.

Members of SGML SIGhyper:

*    receive the "SGML SIGhyper  Newsletter,"  which  keeps  them  abreast  of
     current  technical  information about the emerging applications of HyTime
     and other developments.

*    know who is working in the field, and how to  get  in  touch  with  them.
     Members  receive  the  "SGML  SIGhyper  Directory,"  which lists all SGML
     SIGhyper members who elect to be listed in it.

*    are able to inform other  members  about  matters  of  general  interest,
     through  written  contributions to the "SGML SIGhyper Newsletter," and by
     direct mail to the members.

*    are aware of the availability of exemplary new HyTime documents, document
     type  definitions,  system  designs, and software, when they first become
     available.

*    are represented at ISO HyTime meetings.

CURRENT MEMBERS  OF  SGML  SIGHYPER  are  employed  by  and/or  represent  the

following  organizations: Aarhus University, American Chemical Society, Ameri-
can  National  Standards  Institute,  Apple  Computer,  Inc.,  Aquidneck  Data

MEMBERSHIP IN THE SGML USERS' GROUP. It is not required that you join the SGML
Users'  Group,  but  it's probably a good idea.  The benefits of membership in
the SGML Users' Group include reduced rates at events organized by the  users'
group,  a copy of each issue of the "Bulletin" and "Newsletter," copies of the

standards and technical  reports  at  special  prices,  discounts  on  certain
relevant  books,  and  a 10% discount for the Markup conferences.  To join the



                                    - 3 -


SGML Users' Group, you should send your name, affiliation,  position  in  your
institution  or  company, mailing address, telephone and/or facsimile numbers,
telex and/or internet and/or other electronic mailing  address(es),  a  signed
letter  of intent to join, and your annual membership dues of either US $75 or
Lb 40 for an individual, or US $150 or Lb 80 for a corporation, to SGML Users'

THE GRAPHIC COMMUNICATIONS ASSOCIATION (GCA).  SGML  SIGhyper  recognizes  the
crucial  role that the GCA has played and continues to play in the development
of the HyTime standard.  As ANSI X3V1.8M Secretariat, the GCA provides  essen-
tial  sponsorship  for  meetings  and  mailings in support of that committee's
work.  We plan to continue  to  support  HyTime  technical  sessions  at  GCA-
sponsored conferences, such as "TechDoc," "SGML," "Expert Communication," etc.
In addition, due to the rising popularity and use of HyTime, the  GCA  is  now
planning  a  series of conferences devoted solely to HyTime.  For the foresee-
able future, SGML SIGhyper  meetings  will  take  place  during  GCA-sponsored
conferences (the organizational meeting took place at TechDoc '91, in Seattle,
Washington, USA in August, 1991). For  information,  contact  Mr.   Marion  L.
Elledge,  Vice  President,  Information  Technologies,  Graphic Communications
Association, 100 Daingerfield Road, Alexandria, VA 22314 USA  (voice:  +1  703

SGML SIGHYPER ON LINE. Thanks to the efforts of Erik Naggum (the Vice Chairman
of SGML SIGhyper) and the University of Oslo, some SGML SIGhyper documents and
general  information  are   already   available   via   anonymous   FTP   from
ftp.ifi.uio.no ([129.240.88.1]) in the directory "SIGhyper." All new documents
are announced in the USENET group comp.text.sgml as they become available.  If
(and  only if) FTP service can't be used, members may request the document via
the internet from [e-mail].  An alternative source node for
SGML SIGhyper on-line documents is at Florida State University; the address is
mailer.cc.fsu.edu (128.186.6.103); the directory is pub/sgml.

At both FTP nodes, there is also a public-domain SGML parser in  the  form  of
both  C source code (for either Unix or MS-DOS) and MS-DOS executables.  Known
as "ARC SGML," the parser comes with absolutely  no  warranties  of  any  kind
whatsoever.  SGML  SIGhyper  will send (with absolutely no warranties, guaran-
tees, or anything else, for that matter) copies of ARC SGML in  the  following
formats for the following prices to the following addresses.  (You may be able
to get lower prices by buying directly from the SGML Users' Group.)

Copies of ISO 10744 (HyTime) are currently only available from your  country's
ISO  member body.  Copies of CD 10743 (SMDL) are available from SGML SIGhyper,
as well as from the GCA, and your country's ISO member body.  The  HyTime  and

SMDL standards documents are NOT available in electronic form.  If you wish to
order this document from SGML SIGhyper, the prices are as follows:

Note: You will need the HyTime document in order to understand the SMDL  docu-
ment.   Please  be  informed  that  the  SMDL document has not been revised to
reflect the changes in the HyTime IS, so there is some  inconsistency  between
the two documents.




                                  FOOTNOTES


1.   SGML stands for ``Standard Generalized Markup Language," an international
     standard (ISO 8879-1986) metalanguage for the expression of the structure
     of document types and for tagging the  structural  elements  of  document
     instances  conforming  to  any  particular  document type.  SGML has been
     adopted by many of the world's largest publishers and by many  countries,
     including the US and the EC.

2.   HyTime became an ISO International Standard in April, 1992.

3.   "ISO stands for  "International  Organisation  for  Standardization,"  an
     organization  whose  members  are the national standards-making bodies of
     the participating countries.

4.   The SGML Users' Group is an international group entirely devoted  to  the
     promotion  and exchange of information about the ISO SGML standard (Stan-

********************************************************************************
Dear SGML SIGhyper Member,

I am writing this letter to explain the reasons for the long delay we
are experiencing in publishing the second issue of the _SGML SIGhyper
Newsletter_, and to try to keep you informed while that (large) issue is
unavailable.  You can think of this letter as an interim newsletter.

When you joined SGML SIGhyper, you were betting on HyTime's early
appearance as an international standard.  I'm very pleased to report
that you bet wisely.  HyTime was adopted by the ISO and IEC as a
full-fledged International Standard on May 1, 1992.  HyTime has the
distinction of being the _only_ international standard for representing
the structure of hypertext and multimedia documents.  It is reasonable
to expect the pace of HyTime activities, and the frequency of
publication of this _Newsletter_, to pick up considerably from now on.

Unfortunately, there were a number of changes required by the editing
instructions given to the Project Editor, Dr.  Charles F.  Goldfarb, by
WG8 when HyTime was adopted, and the final editing of the standard is,
at this writing, not yet complete.  We had expected an early completion
and publishing date, and were therefore delaying publication of the next
_Newsletter_ until such time as we could make a complete report about
the changes to HyTime, and provide updated and new examples of the use
of the IS version of HyTime.  It is now clear that it will be another
month before the standard is published, and we felt that we now had to
send this letter out to inform our members about the reason for the
delay.  Since the wait has been so long, it now looks as though the
current Membership Year will expire (on July 31) before the new
Newsletter will appear.  Therefore, for purposes of _Newsletter_
subscriptions, THE CURRENT MEMBERSHIP YEAR WILL NOT EXPIRE UNTIL AFTER
THE NEXT ISSUE, WITH THE HYTIME EXAMPLES AND EVERYTHING ELSE WE ARE NOW
HOLDING, IS MAILED OUT.  In other words, you will not have to pay any
additional dues in order to receive the next full issue.  (Far be it
from us, however, to discourage you from renewing your membership!  We
will send out membership renewal notices after we mail the next issue.)

Since last October's issue was first published, there has been a steady
increase in the number of questions and expressions of support and
interest about HyTime.  SGML SIGhyper now has about 200 members, and we
expect many more very soon, when the International Standard version of
HyTime is published by ISO and distributed by all of its national member
bodies.  Several of you have reported bugs in the example documents in
the first issue of the _Newsletter_, and several have provided a variety
of other materials for publication in the _Newsletter_; we are grateful
for these contributions of effort and interest.

AVAILABILITY OF THE HYTIME INTERNATIONAL STANDARD DOCUMENT.  We have
asked permission to duplicate HyTime, so that our members can continue
to enjoy ``one-stop shopping'' for all their HyTime documentation needs,
but we have not yet received a reply to that request.  If we do receive
such authority, it seems certain that each copy we make will involve a
royalty expense, which we will have to pass on to you along with our
usual duplicating, handling, and mailing charges.  The ISO quite
literally owns the text of its standards, and that is a good thing,
because its ownership protects the integrity of the standards.

ELECTRONIC COPIES OF THE HYTIME INTERNATIONAL STANDARD DOCUMENT.  On a
related topic, many of you have asked for electronic copies of the
HyTime standard.  For a variety of good reasons, the electronic version
is not available.  Unless the ISO changes its policy on this point (and
there is currently a firm ISO-imposed embargo on electronic publishing
of standards), you can be certain that any electronic versions of
recently-released ISO standards you may come across are unauthorized and
not to be trusted.  On your behalf, we have argued that it will be
embarrassing to hypertext applications vendors who claim that their
products are HyTime-compliant, if they cannot supply the HyTime standard
itself as a hypertext document with their systems.  At the same time, we
have also made what we see as an even stronger argument that it would be
a bad idea to publish HyTime or any other standard in the absence of any
mechanism whereby users can independently determine that

* the copy of the standard supplied by a vendor is an ISO-authorized,
  royalty-generating copy,

* that the vendor has not contaminated that copy with other text that
  perhaps makes the vendor's product's features appear to be demanded by
  the standard, and

* that the vendor has not altered the text of the standard (or obscured
  any part of the standard by failing to link to it), so as to make the
  vendor's product inaccurately appear to conform to the standard.

The last thing we need is a variety of different versions of the HyTime
standard lying around, and no way to determine whose version is correct.
This would be very undesirable for a variety of reasons, including the
fact that references may be made to HyTime in binding contracts,
national regulations, and in other international standards.  As a
formally adopted International Standard, HyTime is subject to change
only by means of an amendment process, and at regular reviews at
five-year intervals in the normal ISO fashion.

Having said all that, I should also point out that the ISO will place
the HyTime meta-DTD, which is arguably the very heart of the standard,
in the public domain.  We expect SIGhyper, among others, to make it
publicly available via FTP, e-mail, floppy disk, and tape.

PREVIEW OF CHANGES IN THE INTERNATIONAL STANDARD VERSION OF HYTIME.
There are a variety of editorial changes:

* Most of the informative Annexes are gone, in order to make it easier
  to finalize the actual standard.  (The ``Lost Annexes'' will be
  published in a forthcoming issue of the _SGML SIGhyper Newsletter_.)
  These include a description of the behavior of a possible implementation
  of a HyTime engine, some examples representing alignment relationships,
  a description of editorial conventions used in ISO standards, a tutorial
  on SGML, and a description of Integrated Open Hypermedia.

* There is an expanded explanation of categories of HyTime attributes.

* The DIS's ``hub document'' concept has been put into the context of
  the concept of the ``bounded object set.''

* The distinction between HyTime and non-HyTime elements has been made
clearer with the addition of a ``HyTime/non-HyTime Bridge element''
("HyBrid").

* A significant new SGML/HyTime query language, ``HyQuery,'' has been
added.

GENERAL IMPLEMENTATIONS OF HYTIME.  Two companies have separately and
publicly announced their intentions to produce HyTime engines, which are
software modules intended to be used as substrates or back ends for
complete end-user applications.  (The HyTime standard was written in
such a way as to make it practical to produce such engines, and thus to
obviate the need for each implementer of HyTime to ``reinvent the
[HyTime] wheel.'')

* TechnoTeacher, Inc.  has announced that its ``HyMinder'' product will
  be in beta test this summer, and that a general release is planned for
  the fourth quarter of this year.  The announcement was made, and a
  prototype was demonstrated, at TechDoc Winter '92 in Ft. Lauderdale,
  Florida in February.

* Mr.  Martin Bryan (author of the well known _SGML: An Author's Guide_)
  of Sema Software Technology (the source of the MARK-IT SGML
  parser/document analyser and the WRITE-IT SGML-based structured document
  editor) has announced his company's intention to produce a HyTime engine
  product fully integrated with his company's product line around 1995.
  He made the announcement in the course of his presentation on a
  hypermedia system for the support of the European tourist industry now
  under development at Sema, at the International Markup '92 conference in
  Amsterdam in May.

(Note: We have not yet heard of any actual HyTime-compliant end-user
product announcements.  When you hear of any, please let us know so we
can announce them.)

THE ``DAVENPORT GROUP'' is a group of Unix and Open system vendors who
are developing a HyTime-based meta-DTD for the interchange of online
software documentation.  The group has met three times, and the current
draft of the resulting _Davenport Advisory Standard for Hypermedia
(DASH)_ [the DASH was formerly known as the _Davenport Group Draft
Advisory Standard (DGDAS)_] will be published in the next _SGML SIGhyper
Newsletter._ The basic idea is to provide a standard for interchangeable
``navigation information'' about documents, so that, for example, any
reseller of a documentation product can incorporate references to parts
of documents in a master topical index to all the documents sold with a
system, emanating from a variety of sources.  Active participants in the
work include representatives of Avalanche, Computervision, Electronic
Book Technologies, HaL, Hewlett-Packard, IBM, Lotus, Novell, O'Reilly &
Associates, Open Software Foundation, Open Systems Solutions,
TechnoTeacher, and Unix System Laboratories (the foregoing is not a
complete list).  If you would like to become a participant in the DASH
design work, you should contact the Chairman, Mr.  Dale Dougherty,
Manager, Digital Media Group, O'Reilly & Associates, Inc., 103A Morris
Street, Sebastopol, California 95472 USA.  (tel: [phone]; fax:
[phone]; uucp: uunet!ora!dale; internet: [e-mail]).  The
most recently published draft of the DASH is also available as a
PostScript file via FTP from mailer.cc.fsu.edu (128.186.6.103) in the
directory ``pub/sgml/DAVENPORT.''

With this letter, I have attempted to give you a feeling for some of the
kinds of things that are going on with HyTime.  There is much more to
tell, and we will do our very best to get the next _Newsletter_ into
your hands, with the detailed information you need, as soon as possible.
In the meantime, please share your news, questions, and comments with
us, so we can share them with you.


Sincerely,
