Space Based Computing as Semantic Middleware for Enterprise Application Integration
Objectives
Space based computing (SBC) is an
innovative and powerful concept for the coordination of autonomous
processes. It is based on the notion of a common, abstract space
connecting distributed processing entities over a network. Instead of
explicitly exchanging messages or performing remote procedure calls,
processes communicate and coordinate themselves by simply reading and
writing distributed data structures in a shared space. Synchronization
is carried out through the access of data in space which might block,
if the denoted data are not yet here. The wake up occurs on data driven
basis supporting event-driven architecture conceptions. This leads to a
decoupling of all participants concerning time, space and reference.
The space inherently offers the advantages of state-full communication,
transactional security, asynchrony, near-time event notification,
scalability and software-fault tolerance through replication.
A space offers a high level abstraction
for developers hiding complexity that otherwise would be reflected in
the application code thus reducing development time and costs in
distributed applications. It offers a lean application programming
interface but nevertheless exhibits a high expressiveness.
The SBC paradigm was originally applied
for parallel computing and dates back on the invention of the Linda
model by David Gelernter in the late 1980s. Since then, many facets of
spaces have been proposed and research has shown that promising new
technologies, such as Semantic Web, Service Oriented Architectures
(SOAs), mobile computing, GRID computing, robotics, and agent
technologies, require new approaches towards distributed systems that
can profit from SBC. Nonetheless, the paradigm is currently not known
enough to a broad audience and SBC approaches have not yet gained
enough industrial attention.
The workshop aims at studying the paradigm
in the context of semantic middleware for enterprise application
integration, exchanging about current developments and applications. It
has the goal of raising awareness and visibility of the SBC paradigm in
industry, to showcase solutions, to point out ways of how SBC can be
exploited by industry and unfold its power in commercial applications
and projects, and to build a community for researchers, developers and
users. As a midterm goal, it wants to see a convergence of space based
platforms in order to include SBC into current EAI standardization
effort.
Call for Papers
This workshop seeks papers studying and
discussing the space based computing paradigm in the context of
semantic middleware for
enterprise application integration to exchanging about current
developments and applications experiences and challenges. The papers
contents shall promote the paradigm to industry at ESTC and to start
community building.
Topics of interest include but are not limited to:
- Business cases and scenarios in which SBC exhibits business advantages and enables new application possibilities
- Demarcation of SBC towards other paradigms like Message Queues, Publish/Subscribe , RPC or databases
- Studies on existing and emerging target markets for SBC
- Studies on new application scenarios that become possible with SBC
- Enhancing and influencing mainstream web standards by the SBC paradigm: WSDL, SOAP, WebServices, Business Processes etc.
- Modeling of space interactions and patterns that go beyond message exchange patterns for EAI
- Employing semantics to describe the space (e.g. ontologies for a meta-model, security etc.)
- Impacts and importance of SBC on the possibilities of Semantic Web
- Definition of a higher-level infrastructure for the intelligent
and reliably distribution and publishing of semantic and RDF based
information in the web based
- SBC based platforms and their architectures
- Extending the classic Linda coordination model by more structure and openness
- Paths towards standardized space APIs
- Definition of necessary communication protocols for the Internet
All submission must be oriented towards the uptake of the paradigm in industry, which excludes purely theoretical work.
Submissions are welcome from both industry and research practitioners.
Accepted submissions will be invited to give a presentation at the workshop.
