Important News!

Techquila no longer offers consultancy, development or training services as the efforts of Kal Ahmed are now focussed on a new company, NetworkedPlanet, offering topic map tools and applications developed for the Microsoft .NET platform.

It is my intention that Techquila should remain a source of open software, open data, and open ontologies and that the free and open-source software developed during the "Techquila-days" (as they are now known) should remain here and continue to be developed as an when the pressure of running a "proper" company allows.

I would just like to thank all of the friends, colleagues and clients that helped to make my time as an independent consultant a great success. Now, on to the next challenge!

Open Software

On this site, you will find :

• TMTab a plugin for the Protégé ontology editor that allows you to build an ontology that can then be exported as a topic map in standard XTM syntax.
• MDF - the Meta-Data processing Framework, a Java toolkit for extracting data from a variety of sources and munging it into topic maps or RDF.
• RELAX-NG Documentation Tools - a set of XSLT stylesheets for generating Docbook documentation and SVG graphics from a RELAX-NG schema.

I am still also heavily involved in developing TM4J the open-source topic maps toolkit for Java.

Open Data

Techquila is a source of freely downloadable topic map data covering a wide variety of subjects, from The diary of Samuel Pepys to the W3C XML Schema Specification.

This site is also an archive for some of my previous publications, mainly on the subject of topic maps.

Open Semantics

The Techquila domain is used as the namespace for a number of Published Subject Identifiers relating to classification, hierarchical organisation and faceted organisation using topic maps. These PSIs will remain on this site, and continue to be maintained as needed.
