CXTM Test Suite 0.1

Lars Marius Garshol announced that "We now finally have a release of the first version of the CXTM-based test suite for Topic Maps engines. It consists of 293 tests using four different syntaxes: XTM 2.0, CTM, LTM 1.3, and TM/XML. The tests have been verified using two different Topic Maps engines (OKS and tinyTIM), and should be reasonably reliable even at this early stage."

Perl TM now supports XTM

Robert Barta has added XTM support to Perl TM now at version 1.41.

"During the last days I have added - without much enthusiasm, mind you - XTM support, for versions 1.0, 2.0 (and the intermediate 1.1). Especially 1.0 is cumbersome programming. Let's thank the XTM editors for the much simpler version 2. Support means deserialization and serialization, so you should be able to create valid XML instances in all the above flavors."

TMPlusPlus Beta

Inge Henriksen announced the release of his open source C++ Topic Maps engine. It has bindings for lots of scripting languages:

"My first main goal with this new engine was to enable C++ programmers (the same programming language in which TM++ is written) to be able to use topic maps in their programs. The second goal was to make a really fast topic maps engine without having to fall back on caching and the likes. The engine is based around TMDM 1.0, and you can also work with XTM 1.0 and XTM 2.0 files."

Wordnet converted to a Topic Map

Aki Kivela announced that an RDF version of Wordnet has been converted to a Topic Map by Wandora. Now there is a nice data set to load into your engines. "we have converted the WordNet to a topic map. Topic map is in XTM format. Wandora project file is also available."

TMDM and XTM2.0 finalized

Lars Marius Garshol announces the (almost) fruition of 5 to 6 years of work. Well done!

TM/XML

Lars Marius Garshol has written a blog entry on a new XML format for Topic Maps. "The best way to think of TM/XML is as a kind of LTM-in-XML, in the sense that like LTM is more human-friendly than XTM, and also like LTM it is not in any way standardized. It's just a proposal, to be implemented in Ontopia software, which anyone else can implement if they want to."

XTM is not Topic Maps

Lars Marius Garshol makes his case that XTM is not Topic Maps, ie. the syntax is not the same as the data model. This will be a familiar argument to those who read the TM mailing lists.

New Zealand Electronic Text Centre

The New Zealand Electronic Text Centre has relaunched its website based on TM4J. Conal Tuohy reports that "The topic map presently contains 46807 topics, 192492 associations, and 43942 occurrences; roughly 150Mb of XTM. We are using tm4j's "in-memory" back-end, running on Java 1.4.1 on Windows 2000. The topic map consumes approximately 1.3GB of RAM."

Tm4JScript Released

Alexander Johannesen and Thomas Passin have announced that Tm4JScript has been released at SourceForge. "The system runs stand-alone in a browser... The engine is based on reverse-engineering of xtm into an object model. It is a very straightforward design that uses indexes and hash tables to get performance. There are a number of useful methods that more or less make up for not having a query language. The system consists of the core engine, utilities code, and the editor app. A few other apps are also included in the distro."

TopicMaps.Org moves to OASIS

The XTM mailing list has now been closed as Topicmaps.Org moves to OASIS. This follows the general consensus that the "isness" of topic maps should be defined at ISO and that ISO is, to quote Steve Newcomb, "the appropriate locus for the
process of rigorously establishing the essential nature of topic map information." Application specific work will continue to be done at OASIS. A corollary of this is the closure of the XTM mailing list and the creation of new public and members lists at OASIS.
