W3C Unified Service Description Language Incubator Group
This XG started on 17 September 2010 and closed on 27 October 2011. See the
Final Report.
The
mission
of the Unified Service
Description Language Incubator Group is to define a language for describing
general and generic parts of technical and business services to allow services
to become tradable and consumable. See the
charter
for more information.

About the Unified Service Description Language XG
The USDL XG was initiated by Attensity, DFKI, SAP, and Siemens in September
2010. It will take the current and available specification of USDL and form it
to the needs of the standardization body. In order to get a most valuable and
comprehensive result, the work in the XG is basically split in three work
streams:
Investigate related standards and approaches, position and integrate the
USDL activity
Re-design USDL to include feedback, requirements and related work
Define and implement reference test cases to validate USDL
The final outcome will be a report with a reworked USDL specification and an
assessment of how to proceed with USDL in September 2011. More information
about the XG can be found in our
Wiki
. USDL is one part
of the
Internet of Services
initiative. This page contains more information about USDL and our vision of
the Internet of Services. You can also contact the chair (
Kay Kadner
) if you have any questions or
concerns.

About USDL
The Unified Service Description Language (USDL) is proposed as a “master
data model for services” to describe various types of services ranging from
professional to electronic services. It aims at a holistic service description
putting a special focus on business aspects such as ownership and provisioning,
release stages in a service network, composition and bundling, pricing and
legal aspects among others, in addition to technical aspects.
First iterations of USDL were solely built by SAP Research expending several
person years of effort. About a dozen researchers at SAP Research contributed
to the model by bringing in their expertise from different backgrounds
(computer scientists, incl. security and SLA experts, business economists,
legal scientists, etc.). This was carried out in the context of several
publicly funded research projects under the Internet of Services theme. The
current specifications of this work stream can be found at
www.internet-of-services.com and is known as USDL3.
Subsequent iterations of USDL include the contributions and evaluation
feedbacks of partners external to SAP Research. As an example, the German
Fraunhofer FOKUS institute is prompted to include aspects such as identity
management and Siemens evaluates USDL in controlled experiments in their
setting. Finally, the scope of input is broadened even wider by approaching a
standardization body starting with this Incubator group.
