Dear all,

we are currently using on Ontology Language for the following
projects (and intent to switch over to WOL as soon as possible):

We use an ontology language to define the vocabulary necessary
to construct websites and portals.
We have built ontologies which capture different aspects of web site and
web portal construction (e.g., the primitives needed to built the navigation
model of a website are specified by an ontology).
Since the content of the portal is also given by instance data
adhering to a domain ontology, the same tools can be reused at several
layers - for the construction primitives as well as the content of the website.

The tools helping to construct the website are ontology driven,
which results in a nice separation of code and data and enhances the
level of reuse as well as extensibility and maintainability of the 
resulting code.

within LastMileServices:
LastMileServices is a startup
aiming to describe static and dynamic aspects of
telecommunication devices, with the goal of simplifying
service construction and configuration of large networks.

We use on ontology language to define device ontologies
(e.g., router and switches)

For capturing the dynamic aspects of device configuration
we have developed a service description ontology,
which defines primitives to declare task decomposition,
control flow (using the vocabulary of a UML statechart),
and data flow of services.
Other primitives enable to create new services by combining and
configuring existing services.
This results in a compositional ontology-based process and service
description language capable to  combine existing services
(given by, e.g., distributed Web Services or
Java Objects) with the goal to create new services.

A service description can be compiled to Java code and be executed.

All the best,
