Smart-M3 is a name of an open-source software project that aims to provide a ''Semantic Web'' information sharing infrastructure between software entities and devices. It combines the ideas of distributed, networked systems and semantic web. The ultimate goal is to enable smart environments and linking of real and virtual worlds.〔Ian Oliver (ed.) (M3 Information SmartSpaces Technology Overview. Nokia Research Center Technical Report NRC-TR-2009-M3-1 )〕〔Ian Oliver, Ora Lassila (2011) (Integration In The Large. W3C Workshop on Data and Services Integration )〕 The key idea in Smart-M3 is that devices and software entities can publish their embedded information for other devices and software entities through simple, shared information brokers - a ''push''-based information sharing model rather than specific publish-subscribe. The understandability of information is based on common ontology models common data formats. Another key idea is that Smart-M3 is device, domain, and vendor independent. It is free to use, open-source solution available in BSD license. So, Smart-M3 refers to a piece of software technology, several software products encoding this software technology, a computing platform that the software products make available, and any computing system that has been developed and deployed by using this computing platform. The Smart-M3 software technology〔Oliver Ian, Jukka Honkola(2008). “(Towards the Dynamic Semantic Web )”. Presented at TripCom 2008〕 is an evolving development of the Semantic Web with some specialized properties.〔Oliver Ian, Honkola Jukka (2008). “(Personal Semantic Web Through A Space Based Computing Environment )”. Presented at ICSC 2008〕〔Oliver Ian, Honkola Jukka, Ziegler Jurgen (2008). “Dynamic, Localized Space Based Semantic Webs”. IADIS WWW/Internet 2008. Proceedings, p.426, IADIS Press, ISBN 978-972-8924-68-3〕 The Smart-M3 software products are open-source software. They are available at sourceforge. The Smart-M3 software products enable implementation of an Smart-M3 computing platform. The Smart-M3 computing platform allows to store and retrieve information based on tuple space mechanisms. Like in Linda (coordination language), a small defined set of semantically based interaction capabilities exists. A programmer can develop pieces of software that will make use of these interaction capabilities. A number of Smart-M3 software products are available that support such software development. Any such software must comply to the defined interface of the Smart-M3 computing platform, the defined communication protocol and the general design principles. A Smart-M3 system〔Honkola Jukka, Laine Hannu, Brown Ronald, Oliver Ian (2009). “(Cross-Domain Interoperability: A Case Study )”. (Lecture Notes in Computer Science, Volume 5764/2009, p. 22, ISBN 978-3-642-04188-4 ). Presented at ruSMART 2009〕 is existing when such pieces of software have been built and deployed together with the Smart-M3 computing platform. The Smart-M3 is being developed at Nokia Research Center within Artemis JU programme in Sofia (smart objects for intelligent applications) and in Finnish national DIEM (Device interoperability ecosystem) research projects.〔 Liuha, P., Lappeteläinen, A., and Soininen, J-P. (Smart Objects for Intelligent Applications - first results made open ), ARTEMIS Magazine, October 2009, No. 5, pages 27-29.〕〔Koljonen, T. (ARTEMIS and the rest of the world ), ARTEMIS Magazine, October 2009, No. 5, pages 30-31.〕 == Technology == Smart-M3 takes aim of the multi-vendor, multi-device and multi-part issue〔Soldatos John, Alexopoulos Dimitris (2006). ( “Web Services-based network management: approaches and the WSNET system”. ) International Journal of Network Management, Volume 17 Issue 1, Pages 33 - 50. Wiley InterScience.〕〔Farley P., Capp M (2005). (“Mobile Web Services”. ) BT Technology Journal, Volume 23, Number 3, p. 202-213, ISSN 1358-3948 (Print) 1573-1995 (Online) . Springer.〕〔Liuha Petri, Soininen Juha-Pekka (2008). (“Devices and Interoperability Ecosystem (DIEM)”. )〕 (that's where the term M3 comes from). This M3 issue means that many kinds of devices shall interact with each other, for instance a mobile phone, a television set and a laptop. A device may be composed of parts that are considered as individual partners for interaction with another device. For instance, a user makes use of the keyboard of a desktop computer for typing input to a mobile phone. Further, the user shall be free in choosing the manufacturer. Any piece of software engaging this M3 issue must at least be able to work properly in an environment constrained by these issues. Moreover, the Smart-M3 technology allows to build pieces of software that are able to take advantage of the opportunities such an environment offers.〔Oliver Ian, Törma Seppo, Nuutila Esko (2009). “Context Gathering in Meetings: Business Processes Meet Agents and The Semantic Web”. Presented at TCoB 2009〕〔Jantunen Joni, Boldyrev Sergey, Oliver Ian, Honkola Jukka (2009). ”Agent/Space-Based Computing and Radio Frequency Memory Tag Interaction”. Presented at IWERT 2009〕 When humans make use of the Web, they produce and consume human readable information and exchange this information based on the paradigm of 'persistently publish and actually read'. A piece of software executing in a device used by humans may transform, render, analyze and index that human readable information, but this software will not understand the information.〔(Web Architecture from 50,000 feet ). W3C〕 Also the technology of the Smart-M3 approach does not make such human-human communication machine-understandable. Instead, Smart-M3 follows the principle of the Semantic Web that machine-understandable information has to be prepared explicitly for software reasoning.〔Berners-Lee Tim, James Hendler, Ora Lassila (2001). ("The Semantic Web" ). Scientific American Magazine.〕 However, instead of specifying explicitly the means of interaction between a piece of software producing data and sending it across the internet to a piece of software consuming that data, Smart-M3 follows exactly the human-human interaction paradigm of 'persistently publish and actually read' also when software interacts with software across the internet.〔(Triple Space Communication )〕 While the notion of the Semantic Web embodies the vision of a single, universal web of machine-understandable information, Smart-M3 organizes the machine-machine communication by setting up in the Web many distinct spots of information exchange. At each spot a number of pieces of software executing in potentially many devices of potentially many kinds may publish and read information. This information has been prepared not only explicitly in machine readable form but also explicitly for each particular spot. Any particular spot of information exchange has a particular purpose or focus. All information that a particular spot of information exchange makes available will be dedicated to the particular purpose or focus of that spot. The number of pieces of software exchanging information at a particular spot is consequently limited to those that share this dedication. At the core of the M3 issue is the issue of interoperability. The Smart-M3 approach deviates direct point-to-point interoperability because it applies the 'publish and read' mechanism at dedicated spots of information exchange in the Web. The publishing entity does not need to be interoperable with the reading entity. In fact the two even do not need to know about each other. Instead, Smart-M3 simply takes means that the publisher is able to publish at the selected spot of information exchange and the reader is able to read there. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Smart-M3」の詳細全文を読む スポンサード リンク
