The document describes Smart-M3, an open source platform for building distributed applications using shared information. It discusses key concepts of Smart-M3 including lightweight implementation, accommodating existing systems, and emergent applications. The architecture uses Knowledge Processors that contribute and consume content according to ontologies, and Semantic Information Brokers that manage triples of information. The document provides examples of deploying Smart-M3 and its open source implementation components for Knowledge Processors and Semantic Information Brokers.

2. M3 Concepts
• Information level interoperability
• Simple API to access information, “standard” ontologies
• Independent agents operating on information
• Lightweight implementation
• No heavy infrastructure
• Accommodates existing systems
• Evolution is possible
• “Bridging” walled gardens
• Sharing embedded information

4. Notion of Application
• Agents understand their own, non-exclusive part of the set
of information available in a space
• Applications emerge from actions over the information

• Concepts are independent of used communication mechanism
• SIBs and KPs may have any number of different transports
• KPs are software processes
• The SSAP protocol is the interoperability interface

• C/GLib, Qt, Python KP APIs with TCP/IP and NoTA connectivity
• SIB with TCP/IP and NoTA connectivity
• Ontology library generators for C/GLib and Python APIs
• Documentation for building the system
• Future development (already underway)
• Java and C# KP APIs
• “ANSI-C” KP API
• Ontology generator for “ANSI-C” KP API
• Demos are released separately
• No demos available yet, but VTT will release their Smart-M3 based demo as open
source

9. The Smart-M3 Release – Knowledge Processor
• libwhiteboard: C/GLib based API for KPs
• Integration with GLib main loop for GUI applications
• qt_kp_core_api: Qt based API for KPs
• Integration with Qt main loop for GUI applications
• Qt advanced API will be released in near future
• Depends on GLib also via whiteboardd and DBus connections
• whiteboardd: Daemon for handling connections from KPs to SIBs
• Handles most of the work in KP-SIB connections
• sib-access-*: Transport-specific components of KP
• One for each implemented transport, corresponding components also on SIB side
• Python-KP: Python KP API
• Self-contained, new version will be released in near future

10. The Smart-M3 Release – SIB
• sibd
• The SIB, implements the SIB operations
• Depends on GLib and DBus, contains optional Python parts (WQL)
• sib-nota, sib-tcp
• Transport specific components of the SIB, correspond to sib-access-* on KP side
• Depend on GLib and DBus
• piglet_m3
• The RDF store used by the SIB

Specification Ontology descriptions Ontology library
of ontology in RDF
Ontology typedef struct {
person_list *persons;
Ontology X device_list *devices;
} personal_ontology;
spec
Ontology typedef struct {

Ontology Generator int age;
} person;
Ontology Y person_ontology* init();
int set_person ( person *p );
spec int get_person ( person *p );
...
• Description in RDF using OWL (or some other ontology description language)
• Present the information in SS as a native programming language data
structure and functions to sync it with Smart Space
• Generation currently available for C/GLib and Python APIs, “ANSI-C” in
