Dear all:
eClassOWL, initially released in 2004, has since been the most
comprehensive and mature Web ontology for types of products and
services. It defines classes for more than 30,000 product types and more
than 5,000 properties for product features.
Under the hood, eClassOWL is a non-trivial transformation of the e...@ss
standard [1].
eClassOWL complements the GoodRelations ontology [2] in the sense that
- eClassOWL can be used to describe the product type and features, and
- GoodRelations can be used to describe the offer and other commercial
aspects.
We just replaced the pretty dated documentation and primer Web page at
http://www.heppnetz.de/projects/eclassowl/
so that it better explains the interplay with GoodRelations etc. and is
based on the current state of Web engineering.
The full theoretical background is described in [3] and [4].
Notes:
=====
- eClassOWL 5.1.4 is based on eClass 5.1.4, while the latest version of
e...@ss is now 6.1.
- We are discussing an official release of eClassOWL 6.x these days, but
it may take a while.
- Due to backward compatibility issues, eClassOWL 5.1.4 still uses hash
URIs and is pretty large (in total > 60,000 classes, 30 - 70 MB file
size depending on the format). As per the nature of hash URI-based
ontologies, any application dereferencing a single element will always
request the full file. This will change in any future release, but is a
limitation of the current state.
- Due to licensing issues, eClassOWL 5.1.4 is available freely for
research purposes only. Commercial usages will require a bilateral
agreement with e...@ss e.V.
Acknowledgments:
===============
We would like to thank eClass e.V., in particular Friedhelm Hausmann and
Thomas Einsporn, and Jos de Bruijn, doug foxvog, Axel Polleres, and Amit
Sheth for their kind support and feedback over the seven years of the
project. The work on eClassOWL was partly funded by Florida Gulf Cost
University, by the European Commission under the project DIP (FP6 -
507483), and by the Trans IT Entwicklungs- und Transfercenter at the
University of Innsbruck.
