The Japanese Core-to-Core cooperation programme has been providing the framework for this work- shop. This farsighted programme does encourage and support Japanese centers of research excellence to widen and deepen their scientific connections to other research centers around the world. For this purpose, scientists from Europe, from Northern America, and from other regions such as New Zealand decided to go to Dagstuhl Castle, Germany, to meet a larger group of Japanese scientists headed and coordinated by Dr. Yuzuru Tanaka, professor and director of the Meme Media Laboratory at Hokkai- do University Sapporo, Japan. Tanaka's research center is strong in and world-wide known for its work on knowledge media tech- nologies. For almost half a century, the transformation into a knowledge society has been recognized world- wide. Science and technologies as well as politics strive hard to act appropriately. With the advent of global communication networks, the development and exchange of information is boosted. Combinations of knowledge media sources open unpredictable potentials. But most sources on the Web are not prepared to be effectively combined with other sources. What is known as the enterprise application integration problem locally shows even more seriously and with higher potential impact globally. The Japanese programme on Knowledge Media Technologies for the Advanced Federation, Utilization and Distribution of Knowledge Ressources addresses one of the most important scientific and engi- neering issues of the present and the near future. The work belongs to the wide field of information and communication technologies, but is surely relevant to all other disciplines. The workshop programme is completed by three sessions on Digital Games. This field is a rather new discipline with high economic, scientific, and social potentials. Issues of game knowledge lead to a natural integration of these sessions into the workshop program, although the Digital Games sessions are not reflected in the present proceedings. Preparing the proceedings of this First International Core-to-Core Workshop has been a great pleas- ure. We are looking forward to invaluable cooperations of an unforeseeable reach and impact.

Jantke Ilmenau, July 2006 Gunther Kreuzberger 3 A Formal Model for the Proximity-Based Federation among Smart Objects Yuzuru Tanaka Meme Media Laboratory Hokkaido University N13, W8, Sapporo, 060-8628 Japana tanaka, fujima, ohigashi @meme.hokudai.ac.jp Abstract This paper proposes a new formal model of autonomic proximity-based federation among smart objects with wireless network connectivity and services available on the Internet. Federation here denotes the definition and execution of interoperation among smart objects and/or services that are accessible either through the Internet or through peer-to-peer ad hoc communication without previously designed interop- eration interface. This paper proposes a new formal model for autonomic federation among smart objects through peer-to-peer communication, and then extends this model to cope with federation among smart objects through the Internet as well as federation including services over the Web. Each smart object is modeled as a set of ports, each of which represents an I/O interface for a function of this smart object to interoperate with some function of another smart object. Here we consider the matching of service- requesting queries and service-providing capabilities that are represented as service-requesting ports and service-providing ports, instead of the matching of a service requesting message with a service-providing message. Our model extracts the federation mechanism of each smart object as its interoperation interface that is logically represented as a set of ports. Such an abstract description of each smart object from the view point of its federation capability will allow us to discuss both the matching mechanism for federation and complex federation among smart objects in terms of a simple mathematical model. Applications can be described from the view point of their federation structures. This enables us to extract a common sub- structure from applications sharing the same typical federation scenario. Such an extracted substructure works as an application framework for this federation scenario. This paper first proposes our mathemati- cal modeling of smart objects and their federation, then gives the semantics of our federation model, and finally, based on our model, shows several application frameworks using smart object federation. 1.

Entschlüsselt: Das Geheimnis der Professionalität S. 18 Malcolm Gladwell über die 10.000-Stunden-Regel und andere unangenehme Wahrheiten editorial Zeitgeist Die Marktwirtschaft biete zwei Wege, reich zu werden. Einmal durch Arbeit und zum anderen durch Spekulation. Mit dem Spekulieren geht es schneller und müheloser, aber die Gefahr des ungebremsten Absturzes in die Armut macht die Sache riskant. Nachdem wir gerade den Crash der Weltbörsen erlebt haben und in eine von aberwitzigen Spekulanten verursachte Finanzkrise gestolpert sind, ist es nur logisch, dass jetzt wieder frühes Aufstehen und harte Arbeit zum Leitbild erhoben werden. Der amerikanische Wissenschaftsautor Malcolm Gladwell, dem wir Sprachentraining unsere Titelgeschichte (ab Seite 18) verdanken, scheint den richtigen für Fach- u. Führungskräfte Riecher gehabt zu haben, denn sein neues Buch „Überflieger“ passt genau zum Zeitgeist. Die Botschaft lautet: Wer beim Sport, im Management oder sonst wo an die Spitze will, braucht Talent – aber viel mehr noch intensives, jahrelanges Training. Die Phase vom Anfänger • Kursinhalte auf Ihren zum Könner dauert auf vielen Gebieten zehn Jahre. Berufsalltag zugeschnitten Die Größe Gladwells besteht darin, dass er nicht auf die alten „Positiver-Denken-Sprüche“ (Motto: Jeder ist seines Glückes Schmied) • Kursplanungen nach Ihrem zurückgreift, sondern klar analysiert, dass niemand ohne die Hilfe und persönlichen Zeitplan das Feedback anderer ein auch nur halbwegs vernünftiges Training zustande bekommen würde.
