Subject: OASIS TC Call for Participation: OASIS Semantic Execution Environment Technical Committee

     A new OASIS technical committee is being formed. The OASIS Semantic 
Execution Environment Technical Committee has been proposed by the members 
of OASIS listed below.  The proposal (below) meets the requirements of the 
OASIS TC Process [1].  The TC name, statement of purpose, scope, list of 
deliverables, audience, and language specified in the proposal will 
constitute the TC's official charter. Submissions of technology for 
consideration by the TC, and the beginning of technical discussions, may 
occur no sooner than the TC's first meeting.

      This TC will operate under our 2005 IPR Policy.[2]  The eligibility 
requirements for becoming a participant in the TC at the first meeting (see 
details below) are that:
      (a) you must be an employee of an OASIS member organization or an 
individual member of OASIS;
      (b) the OASIS member must sign the OASIS membership agreement (see [3]);
      (c) you must notify the TC chair of your intent to participate at 
least 15 days prior to the first meeting, which members may do by using the 
"Join this TC" button on the TC's public page at [4]; and
      (d) you must attend the first meeting of the TC, at the time and date 
fixed below.
      Of course, it also will be possible to join the TC at a later time.

      Standards always are improved by broad participation.  Non-OASIS 
members who wish to participate may contact us about joining OASIS 
[3].  Our rules and structure are designed to promote inclusiveness. We 
look forward to assisting parties interested in joining the community of 
implementers, technologists, academics and end-users working on OASIS 
standardization projects.  All also are welcome to take advantage of the 
public resources maintained for each TC: a mail list archive, document 
repository and public comments facility, which will be available via the 
TC's public home page at [4].  Archives of the TC's mail list and public 
comment lists, as with all OASIS TCs, will be visible at [5].

      Further information generally related to the topic area addressed by 
this TC may be found on the Cover Pages at  "Semantic Web: Projects, 
Initiatives, Specifications":

      Please feel free to forward this announcement to any other 
appropriate lists.  OASIS is an open standards organization; we encourage 
your feedback. JBC

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.
