the Web revolutionized the Internet usage for humans"

The Concept (2)
Communication platform for Semantic Web
services based on Web principles:
“Persistently publish and read
semantic data that is denoted
by unique identifiers”
Fundamentals:
• Space-based computing – sharing information,
knowledge
• RDF triples of the form: <subject,predicate,object>
• URI – Uniform Resource Identifier

Tuple Space Technology
•
Asynchronous Communication by persistent publication in a
shared Space without the need of a single central coordinator
•
3fold decoupling of dimensions of information exchange:
1. Processes do not need to address their communication partner,
i.e., are completely decoupled in reference.
2. Communication is asynchronous since the space guarantees
persistent storage of data, i.e., processes are completely
decoupled in time.
3. The processes run in completely different computational
environments as long as they can access the same space, i.e.,
processes are completely decoupled in space.

Semantic Web Technology
• Shortcomings of the current Tuple Space models:
•
•
•
•
lack of namespaces
lack of unique identifiers
lack of semantics (how do tuples relate in the space)
structures (ontologies) for describing the information content
of the tuples
• RDF/RDFS, WSMO!
• Graphs of <subject predicate object>-triples make up a
structured Triple Space!
7
Web Service Technology
•
•
•
Current Web Services technologies (WSDL, SOAP, UDDI) are not so
much about the Web
They mainly use (synchronous) message exchange over Web protocols
Process and application integration is inflexible
•
How did the Web revolutionize human communication? By persistent
publication, and searching information put by others on the Web
 This is much closer to TupleSpaces than to RPC-Style Web Service
Technologies around WSDL and SOAP!

Triple Spaces
Triple Spaces provide a communication paradigm for
anonymous, asynchronous information exchange
that ensures the persistency and unique identification
of the communicated semantic, semi-structured data.

Triple Space Communication
Basic entities:
• Triples
 The semantic data exchanged or shared
• Triple Space
 The space used to exchange or share triples
• Triple Space server
 The infrastructure / server hosting Triple Spaces
12
Triple Space Communication
Triple Space architecture:
• Communication protocol for data exchange
• Communication interfaces
• e.g., write(triples) and read(query) over HTTP
• Triple Space operations layer
•
•
•
•
Query handling
Reasoner bindings
Triple Space management (delete, empty, create…)
Data Store management (resource bindings…)
• Storage component
• RDF Store, file system…
13
Core Objectives from the Proposal
1. Improve the ideas of Tuple Space computing by
adding semantics
2. Integration of Web service infrastructure with the
newly emerging Triple Space
3. Establishing a novel Semantic Web service
paradigm
4. Address the lack of standardized business data
ontologies
5. Scalable and linkable Triple Space storage
6. Security and trust mechanisms

Exploitation Strategy
1. Enhance existing products of the commercial
partners of TripCom, e.g. Telefonica
1. Leverage TripCom implementations of semantically
enhanced service interaction patterns
2. Target BPEL Standardization
3. Incubator programme for "Serviceoutsource.com"
4. Target public sector as early adopter
2. Identify new business possibilities / raise venture
capital for new start-ups, e.g. CEFRIEL
3. Address other companies via our dissemination
strategy
