| XTM in quest for a new home
After the announcement that
GCA/IDEAlliance will stop to support XTM (XML Topic Maps), the project is
looking for a new hosting organization and the names of OASIS, TEI-c and KnoW
have been the first to be mentioned.
Announced
by Paul Conn, GCA Vice President and IDEAlliance Chief Technology Officer, the
decision appears to be motivated by the independent "business model" of the XTM project, which made
it difficult for IDEAlliance to be involved in the project or to benefit
from it:
Under the current model,
IDEAlliance has none of these responsibilities [project
management, administration, budget and marketing] and therefore neither
provides nor receives much value, and we believe our resources can be better
directed elsewhere
Even a least one observer, Patrick Durusau, has
suggested
that the decision might have been guided by personal matters:
I will refrain from
commenting on the almost certain origin of this arbitrary decision by
IDEAlliance and the childish petulance that urged it.
It seems
likely that Steve Newcomb and Michel Biezunski, both influential GCA members
and founders of the XTM project, were the main cement that bound the XTM project and GCA together -- and
that after their departure from XTM the two pieces had no more reasons to stick
together.

[Michel Biezunski and Steve Newcomb:]
None of the above. As far as we know, there is no
contradiction between ISO's, Topicmaps.Org's, and
Topicmaps.net's views on the nature of topic maps.
- The original ISO Topic maps activity, started in 1995,
ultimately resulted in the publication in January 2000 of
a standard, called ISO/IEC 13250:2000 Topic Maps, that
represents an industry consensus about what topic maps are
and how they can be interchanged. Michel originally
proposed the project to ISO and worked for about 4 years
to build a consensus about it, together with Martin Bryan
and Steve Newcomb. This was a long process, but it
worked.
- In January 2000, we (Michel and Steve) were persuaded that
a subset of the ISO standard should be created that would
be adapted to the needs of the Web community. It would be
expressed in XML, it would use URIs, etc. Since we wanted
it to be created quickly (and we had just concluded a
five-year-long ISO process), we created an ad hoc
organization, called "TopicMaps.Org". Its mission was to
publish a spec within one year. Under our leadership,
TopicMaps.Org was created, chartered, supported, and
sponsored, and the group actually delivered an XTM 1.0
Specification in December 2000 at the XML 2000 Conference
in Washington. Please understand that Topicmaps.Org was
not set up to oppose ISO; XTM is an XML-oriented
derivative of ISO/IEC 13250:2000, and the XTM DTD says so.
As far as we were concerned, the purpose of TopicMaps.Org
was to create the XTM Spec *quickly*. ISO is still
willing to develop activities related to topic maps, and
the high value of the XTM DTD is very well understood by
ISO. As far as we know, there is no unhappiness with ISO
at TopicMaps.Org, either.
- There is an increasing amount of work going on in Topic
Maps Land. There are real-world implementations, product
developments, and the need for enriching the standard with
add-ons (in a way that is somewhat similar to XML's
enrichment via XLink, query languages, etc. -- this list
is very incomplete, and no slight is intended by any
omission).
- Many people are working to establish a common
understanding about the exact nature of topic map
information. The dream of global knowledge interchange
depends on the idea that, at some fundamental level, the
interpretation of interchangeable topic map information is
uniform among all applications.
However, the dream of global knowledge interchange and
federability does *not* depend on any uniformity with
respect to the methodologies used to create, maintain,
render and use topic maps, or even on the idea of a
uniform API to topic map information (although some
agreements about APIs might be very helpful in
jump-starting the industry, just as the DOM and SAX have
been extremely helpful for the XML industry in general).
These are all areas where there must be freedom and
incentive to innovate, and where global standards are not,
strictly speaking, necessary and may, in some cases, even
be inadvisable. In all these areas, diversity should be
encouraged and cherished.
- As far as we know, there is at least one monumentally
important area of general agreement throughout Topic Map
Land: the serialization syntax for interchanging topic
maps in XML, i.e., the XTM 1.0 DTD, which we, along with
*almost* everyone else we know, firmly believe should be
considered as the basis for implementations, for users,
and for creating an information interchange industry that
relies on topic maps. The existence and adoption of the
XTM DTD is one of those rare minor miracles that make
sense technically, politically, and economically. We
support it and we recommend it unequivocally. The XTM DTD
can and should be used *now* as the basis for
interchanging topic maps. There is nothing that prevents
anyone from doing so. It would be even better if
TopicMaps.Org could provide some guarantee that the DTD is
not going to change soon, in order to let the industry
start. We think this is what users care about now. Other
aspects of topic maps will emerge when they are mature.
Anyway, a foundation (the XTM DTD) and a sub-foundation
(the ISO 13250 standard) already exist. Let's use them.
- www.topicmaps.net is a web site where we, Steve Newcomb
and Michel Biezunski, have published the current state of
our thinking on the interpretation and meaning of topic
map documents. We think it will be useful for making
topic maps sharable and federable at large scales. What
we are publishing on this web site has no normative
status; as it describes itself, it's merely "our work in
progress for your information".
On a different "topic" (please excuse the expression):
We don't know what Patrick Durusau meant by his remarks
about GCA/IDEAlliance's decisions regarding TopicMaps.Org.
However, some have interpreted his remarks as a veiled
accusation that we, Michel and/or Steve, exerted our
influence at IDEAlliance in such a way as to cause harm to
TopicMaps.Org.
Neither of us did any such thing.
Also, contrary to what Eric van der Vlist says in his
article, neither of us is currently a GCA member. It is
true that we have each worked for GCA from time to time on a
contract basis, and we have both found much to admire about
the contributions that GCA has made over many years to the
information management and publishing industries. Like many
others, we have also participated in many GCA conferences,
and we have led several tutorials under the GCA banner.

Re: XTM in quest for a new home (Mike Champion - 13:18, 6 Apr 2001) I'm confused about topicmaps.org, topicmaps.net, the original ISO topic maps activity, and this announcement. Is this a personality clash, disagreement on principles, disagreement on technology, or what?
Is there any reason to expect that XML topic maps will emerge from this as a viable, standardized technology that real businesses will care about?
