Ritorno a scrivere di Internet of Things (IoT) e stavolta fermandomi sul punto d’incontro con i Linked Data.
Cities across the world are about to enter the next phase of their development. A near invisible network of radio frequency identification tags (RFID) is being deployed on almost every type of consumer item. These tiny, traceable chips, which can be scanned wirelessly, are being produced in their billions and are capable of being connected to the internet in an instant. This so-called ‘Ambient intelligence’ promises to createa global network of physical objects every bit as pervasive and ubiquitous as the worldwide web itself.
The Internet of Things: imagine a world where everything can be both analogue and digitally approached – reformulates our relationship with objects – things- as well as the objects themselves. Any object that carries an RFID tag relates not only to you, but also through being read by a RFID reader nearby, to other objects, relations or values in a database. In this world, you are no longer alone, anywhere.
In merito ai Linked Data, Sir Tim Berners-Lee alcuni mesi fa si esprimeva in modo chiaro lanciando un messaggio piuttosto semplice per imprese, organizzazioni e governi: rendere i dati disponibili on-line. In tal modo si renderebbero disponibili i collegamenti tra tutti i dati on line, grazie alla tecnologia semantica.
Qual è il legame con l’IoT? Sir Tim Berners-Lee ha detto: “The Semantic Web is a web of things, conceptually. Tying an actual thing down to a part of the web is the last mile “.
Cos’è Internet of Things? In un comunicato stilato dalla European Economic and Social Committee e dal Committee of the Regions, dal titolo “Internet of Things – An Action Plan for Europe” (il testo integrale è disponibile presso l’indirizzo http://ec.europa.eu/information_society/policy/rfid/documents/commiot2009.pdf), si legge:
“Internet of Things (IoT) is not yet a tangible reality, but rather a prospective vision of a number of technologies that, combined together, could in the coming 5 to 15 years drastically modify the way our societies function.
By adopting a proactive approach, Europe could play a leading role in shaping how IoT works and reap the associated benefits in terms of economic growth and individual well-being, thus making the Internet of things an Internet of things for people.”
Internet of Things è stato visto come “metaphor for the universality of communication processes, for the integration of any kind of digital data and content, for the unique identification of real or virtual objects and for architectures that provide the ‘communicative glue’ among these components” . E ancora “RFID is seen as a means of uniquely identifying objects and via RFID in particular, the Internet of Things is being seen as the means of connecting real world items with further data and digital ‘brains’ and vice versa, accommodating too software systems with sensor and context information accessed by RFID tags. What constitutes ‘digital brains’ in this context requires qualification and will undoubtedly be viewed as a collective term for varying degrees of processing capability and intelligent functionality
Di qui al collegamento con la realtà aumentata il passo è breve. Ciò che è meno breve è il tempo necessario per lavorare all’IoT. Una delle domande è se le imprese, i governi e le organizzazioni saranno sono sempre ansiosi (e disposti) di pubblicare online i dati. Tim Berners-Lee parla della
sindrome di progressiva divulgazione della concorrenza, che spinge le organizzazioni a rilasciare in formato aperto sempre più dati. Questa tendenza resta valida anche in un mondo in crisi finanziaria, dove ci sono tendenze a chiudere, invece, le infomazioni e i dati in genere?
Un’altra questione è se i motori di ricerca (cioè le grandi imprese a cui essi fanno capo, nonché i progetti di cui essi sono la realizzazione) si spingeranno sempre più apertamente verso il web semantico.
Tim Berners-Lee, spiega tuttavia come il web of document e il web dei linked data si colleghino e che ci sono segnali che i motori di ricerca si stanno rendendo conto del potenziale del web semantico.
Ecco la roadmap dell’EU : Strategic Research Roadmap e di seguito la
The Tetherless World Constellation designs new techniques to explore social, scientific, and legal impacts of the evolving technologies deployed on the Web. We use powerful scientific and mathematical techniques to explore the modeling of the Web from network- and information-centric views. We aim to make the next generation Web natural to use while responsive to a growing variety of policy and social needs.
The World Wide Web changed the ways people work, play, communicate, collaborate, and educate. But without new research aimed at understanding the current, evolving and potential Web, we may miss or delay opportunities for new and revolutionary capabilities.
To model the Web, to understand the architectural principles that have provided for its growth, and to ensure it supports the basic social values of trustworthiness, personal control over information, and respect for social boundaries, then we must pursue a research agenda that targets the Web and its use as a primary focus of attention.Specific topics to be addressed in the constellation will include:
- Semantic Web Technology
- Knowledge Provenance and Explanation
- Privacy, Policy, and Workflow Transparency
- Tetherless and Mobile Web access
- Trust, Social networking and collaboration technologies for the Web
- Network-centric concepts for the defense, industrial and intelligence sectors
- Cyber-infrastructure in general with initial focus on eScience cyberinfrastructure
- Ontology evolution, management and use in diverse disciplines
- Ethical, Policy and Social aspects of Web use and usability

Semantic Collaboration for Enterprise KM : e-Learning and e-Tourism
This project prepares and starts the commercial exploitation of the semantic collaboration software OntoWiki in the three different target markets Enterprise Knowledge Management, semantically enhanced content management for E-Learning and E-Tourism. OntoWiki is a comprehensive semantic collaboration platform. OntoWiki is open-source software and a Web application, which can be installed at any Web space and accessed by an ordinary Web browser. Onto Wiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing semantic content, similar to WYSIWIG for text documents. OntoWiki is developed at Universität Leipzig and has a large and active user base. Within the course of the project OntoWiki will be further developed and adopted to the needs of the SME participants for exploitation of OntoWiki in the prospective target markets.
