2. Smart-M3 Information Sharing
Platform
• Digital convergence and interoperability
• Ubiquitous computing – communicating devices
everywhere
• The “Giant Global Graph” of Semantic web
• Dynamic and local semantic web
• Serendipitous interoperability

Triple governance transactions using Smart Space: a named
Smart Space Access Protocol (SSAP): search extent of information
join, leave, insert, remove, update,
query, subscribe, unsubscribe Physical distribution
of a Smart Space

KP KP
Knowledge Processor (KP): An entity SIB SIB
contributing to (insert/remove) and/or Semantic Information Broker (SIB):
reading (query/subscribe) content An entity performing triple
according to ontology relevant to its governance in possible co-
defined functionality. A KP needs one operation with other SIBs for one
or more partner KPs for useful sharing Smart Space. A SIB may be a
of content, implying an agreed concrete or virtual entity.

4. Smart Space Access Protocol
• SSAP is the main integration point in M3
• Implementations conforming to SSAP spec can interoperate with others
SSAP operations:
Join Join a named smart space
Leave Leave a smart space
Insert Insert information to smart space
Remove Remove information from smart space
Update Update information in smart space
Query Query for information in smart space using a supported
query language
Subscribe Set up a persistent query to receive notifications when
results change
Unsubscribe Cancel an existing subscription

communication methods

7. Notion of Application
• Applications or scenarios?
• KPs operating on shared information and using shared services
• KPs understand their own, non-exclusive set of information
• Most KPs also have connection to “outside world”
• Scenarios emerge from collective actions of KPs, both in smart space and on
accessible services

10. Knowledge Processors
• A KP contains application logic
communicating with a smart space Application logic
• Ontology API allows developers to use
domain concepts instead of SSAP and
RDF
• Current KPI implementations:
• C/GLib

• C++/Qt

• Python query, subscribe
• Java

• Java/OSGi

11. Future development
• Reasoning support for SIB
• Generic: ontology based reasoning
• Domain-specific: rules engine in SIB
• New operations for SIB
• Atomic conditional update
• Access control
• Joining – who can join a smart space
• Information – who can access specific information in smart space
• Internal KP interface in SIB
• Customization possibilities
