Thought this might be of interest. This appears to be more of an
infrastructure effort and thus likely compatible with ongoing geospatial
semantics work in the OGC - but I am no expert.

OASIS SEMANTIC EXECUTION ENVIRONMENT TC
a. Name
OASIS
Semantic Execution Environment (SEE) Technical Committee
b. Statement of
purpose
The technology of Semantic Web services (SWSs) envisions easy
access to
various systems and facilitates the consumption of the
functionality
exposed by these systems on the Web. Seamless integration,
ad-hoc
cooperation between various business parties or dynamic
collaborations on
the Web, can be achieved only if tools for handling
semantically enhanced
services are provided.
The OASIS SEE TC aims to
continue work initiated by the WSMX project and
working group visible at
http://www.wsmx.org and several other projects in
Europe such as DIP (
http://dip.semanticweb.org/), ASG
(
http://asg-platform.org/) and other projects
in the area of Semantic Web
Services which will start in the coming months.
The aim of the SEE TC is to
provide guidelines, justifications and
implementation directions for an
execution environment for Semantic Web
services. The resulting architecture
will incorporate the application of
semantics to service-oriented systems
and will provide intelligent
mechanisms for consuming Semantic Web services.
Service-oriented
architectures anticipate a large number of ambient
heterogeneous
computational services that may be utilized in various
combinations.
However, a typical composition of services to meet a
business goal often is
an attempt to coordinate disparate resources from
multiple sources -
services that may not know, or fully understand, each
other in
advance. When planning to invoke multiple services, it is not
always
readily apparent whether the methods and outputs of one service meet
the
requirements of another. So some interpretation, mediation or common
understanding is essential for any significant deployment. The SEE TC
will
define methods for using semantic technologies to solve these
coordination
and automation issues.
The TC also will define the
functional components of such an SWS system and
the semantics descriptions
of these components' interfaces. The TC will
also define a formal
description of execution semantics of such a system.
In addition, the TC
will define a generic and open framework, using
metadata, to allow for new
components to be plugged into the system and
made available to the execution
engine dynamically. Further, after
providing the basic methods described
above, or in parallel if appropriate,
the SEE TC will seek to develop
specifications addressing specific problem
sets covering the spectrum from a
general purpose environment to a specific
business-domain-focused
applications addressing financial,
telecommunication, military and
e-Government applications of Semantic Web
Services technologies.
In
the course of existing research, it has become clear that Semantic Web
services and Grid Computing are closely related research activities with
many shared objectives. Both address distributed computing systems from
different perspectives and we believe that they should be investigated in
parallel as complementary technologies enabling the next era of internet
applications. In our vision, the usage of arbitrary resources (physical or
logical) for building complex business applications should be simplified,
so that their discovery, deployment, composition, provisioning and
management, can be performed by the means of semantic-enhanced services. To
reach this goal, on the one hand, current Grid technologies need to be
extended to support semantically enriched resource descriptions and
services, e.g. to simplify their discovery and composition. On the other
hand, Semantic Web services technology has to be extended to support
resource management, including dynamic provisioning of services and
resources, execution management, and support of security-related issues
concerning virtual organization management. This TC aims to combine Grid
Computing with Semantic Web Services technologies and to take advantage of
their different perspectives to provide architecture of the infrastructure
for machine-to-machine enabled communication and cooperation.
The SEE
TC's efforts will foster compatibility across specifications
developed for
Semantic Web Services, and where possible re-use existing
standards and
methods that already have been carried in areas of Semantic
Web and Web
Services. This TC will engage with industry, academic and
research
communities to facilitate understanding, awareness and possible
collaborations regarding emerging semantic technologies and research
applicable to semantically-aware Web Services.
c.
Scope.
Initial requirements have indicated that Semantic Web services
systems
should enable automatic or semi-automatic discovery, negotiation,
selection, composition, mediation, invocation and interoperation of
multiple services. The SEE TC will assess the subsequent and related
works
and implementation experience of existing efforts in a variety of
sectors
(financial, telecommunication, e-health and e-governament) to define
and
implement these functions related with Semantic Web Services. Based on
those experiences, the detailed analysis of requirements for Semantic Web
services Architecture will be provided.
The SEE TC will provide a
testbed for the Web Services Modeling Ontology
(WSMO), which is anticipated
as a contribution for use by the TC on a
non-exclusive basis, and will seek
to demonstrate the viability of using
WSMO concepts, relationships and
definitions as a means to achieve
successful dynamic interoperation of
multiple ambient services, whether or
not they share a common design or
source.
The TC anticipates contribution of the draft WSMX specifications
and WSMO
ontology on a non-exclusive basis. Other contributions will be
accepted for
consideration without any prejudice or restrictions, and
evaluated on their
technical merit, as long as the contributions conform to
this charter.
Following a top-down, component based development approach,
the TC will
provide a whole framework capable of carrying out the dynamic
discovery,
mediation, selection, invocation and inter-operation of Web
Services and
any other functionality which will be revealed during the
requirements
analysis phase. While the focus of this group will remain on a
high level
semantic description of components interfaces, the TC will seek
tight
cooperation with any group working on semantics-enabled functional
components that fulfill the requirements of such system.
The SEE TC
will not implement actual software products or solutions based
on the
specifications developed along the course of work of this group.
d.
Deliverables
OASIS SEE TC will develop two Technical Specifications
described below, and
also may elect to issue Technical Reports and White
Papers:
* Semantic Web Services Architecture and Information Model -
final version
available in December 2007 (the TC may issue intermediate
versions as
frequently as every 6 months)
* Services Specification -
Execution Semantics for Semantics-Enabled
systems - final version available
in December 2007 (intermediate versions
may be available as frequently as
every 6 months)
* Technical Reports will be drafted as appropriate
* White
Papers as appropriate
e. IPR Mode
SEE TC will operate under "RF on
Limited Terms" mode.
f. Anticipated audience
The anticipated
audience for this work includes all OASIS Web Service and
ebXML TCs,
non-OASIS Web Service standards groups, Semantic Web Services
research and
interest groups, SOA architects and programmers, vendors and
users. The work
should be of interest to anyone involved with Semantic Web
Services and more
generally also in Service Oriented Architectures (SOAs).
g.
Language.
English. The TC may elect to form subcommittees that
produce localized
documentation of the TC's work in additional
languages.
