ICSOC04
2nd International Conference on
Service Oriented Computing

New York City, NY, USA
November 15-18, 2004
Co-sponsored by ACM SIGSOFT, ACM SIGWEB, and University of Trento

Service Oriented Computing (SOC) is the new emerging paradigm for distributed computing and e-business processing that is changing the way software applications are designed, architected, delivered and consumed. Services are autonomous platform-independent computational elements that can be described, published, discovered, orchestrated and programmed using standard protocols for the purpose of building agile networks of collaborating business applications distributed within and across organizational boundaries.

Combined with recent developments in the area of distributed systems, workflow management systems, business protocols and languages, services can provide the automated support needed for e-business integration both at the data and business logic level. They also provide a sound support framework for developing complex business transaction sequences and business collaboration applications.

Adopting the service oriented computing paradigm has the potential to bring about reduced programming complexity and costs, lower maintenance costs, faster time-to-market, new revenue streams and improved operational efficiency.

However, before the service oriented computing paradigm becomes reality, there is a number of challenging issues that need to be addressed including among other things service modeling and design methodologies, architectural approaches, service development, deployment and composition, programming and evolution of services and their supporting technologies and infrastructure.

This conference aims to bring together researchers and developers from diverse areas of computing and developers to explore and address these challenging research issues in order to develop a common research agenda and vision for service oriented computing.

STUDENT GRANT PROGRAM

ICSOC 2004 is pleased to announce a Student Registration Grant Program. The purpose of the program is to encourage graduate student participation at the conference by funding the registration costs and providing some amount towards travel and other expenses of students who would otherwise be unable to attend. The funding will be provided in exchange for the students' assistance at the registration desk, as directed by the conference organizing committee. ICSOC 2004 thanks IBM Research for funding the program this year.

Who should apply

Applications are accepted from PhD students at degree granting institutions throughout the world. The funding decisions will be based on the needs expressed by student and adviser in the grant application (see description below) and on how the individual may benefit from the conference and on what she may contribute to the conference.

The funding will pay the conference registration fee of $270.00 (one student registration) and additionally will provide funding of $230.00 to be used towards travel and other expenses. Any PhD student may apply for this support based on evidence of a serious interest in service oriented computing, as demonstrated by PhD research experience and results. The awardees should not receive support from any other award institute for the expenses funded by this program. In exchange, students will be expected to provide assistance at the registration desk during the conference, as directed by the conference organizers.

Who decides

The recipients of the registration grants will be decided by the Awards Chair: Nirmal K Mukhi (nmukhi@us.ibm.com).

How to apply

An application for a registration grant will consist of a letter from the student (in plain ASCII as email, no longer than 1 printed A4 page) and a recommendation letter from the student's adviser (in plain ASCII as email, no longer than one printed A4 page). The letter from the student should:

In addition, the student's adviser should send a letter of recommendation to the Awards Chair: Nirmal K Mukhi (nmukhi@us.ibm.com)

Send the application and recommendation letters by e-mail to Nirmal K Mukhi (nmukhi@us.ibm.com) in plain ASCII as an email message. Letters of support should be no longer than one printed A4 page. Any material beyond that length will not be considered. Requests in other than the specified formats will be rejected. Any questions about the student registration grant program may be addressed to the same e-mail address.

Important dates

A deadline of November 2nd 2004 has been set for the receipt of applications, both for the letter of the student and of the adviser. The recipients selected by the committee will be notified by November 5th 2004. Each recipient will be required to accept the grant by November 7th 2004, so that alternates can be notified in the event that a recipient declines.

PAPER SUBMISSION

One of the goals of the conference is to bring the academic and industrial research communities closer. To this end the conference solicits two kinds of submissions, research and industrial papers, and places emphasis on the SOC industrial program.

Research Papers

The conference is soliciting only original high quality research papers on all aspects of service-oriented computing. Submitted papers will be evaluated on significance, originality, technical quality, and exposition. They should clearly establish the research contribution, its relevance to service-oriented computing and its relation to prior research.

For more information about the Research Papers please send e-mail to: research-papers (at) icsoc.org

Industrial & Applications Papers

The conference also encourages high quality submissions covering innovative service based implementations and novel applications of service oriented technology, or major improvements to the state-of-practice. Actual case studies from practitioners emphasizing applications, service technology, system deployment, organizational ramifications, or business impact are especially welcomed.

Because industry-based authors typically create their submissions on their own time in addition to their normal responsibilities, the conference has different evaluation criteria for industrial and applications papers to ease the burden for such authors. Specifically, such submissions are expected to focus on details and issues surrounding actual implementations and applications, and they need not be as detailed regarding prior art as academic papers are expected to be. Papers submitted to the Industrial Track are also expected to be shorter than academic papers. Industrial Track submissions that do not relate to commercial software and standards, or industrial prototypes in actual use, are not encouraged. Because of these different evaluation criteria, authors must clearly indicate that their submissions are intended for the industrial track (use the "Preference" field in the paper registration form).

For more information about the Industrial Papers please send e-mail to: industrial-papers (at) icsoc.org

Paper Submission Guidelines

Research papers are not to exceed 10 pages in the ACM SIG style and should be submitted in PDF.
Industrial papers are not to exceed 5 pages in the ACM SIG style and should likewise be submitted in PDF.

Full details, including more specific guidelines on the preparation of papers, as well as styles for LaTeX2e, Ms Word and Word Perfect can be found on the ACM website (http://www.acm.org/sigs/pubs/proceed/template.html). Do NOT edit the styles. The use of the LaTeX2e template is highly encouraged.

Every paper should have a cover page that:

Acceptance of a paper means an obligation for at least one of the authors to attend the conference and present the paper.

Paper Submission Procedure

Warning: the submission process is now closed.

To submit your paper, you have to use the online Paper submission system.

You have to register as new author and register your paper before the Abstract submission deadline.
Paper registration includes authors' names and addresses, topic areas, title, keywords, and abstract.

After receiving a registration number you will have to submit your paper, in PDF, before the Paper submission deadline.

Conference Proceedings

    Industrial Service Oriented Architectures

    Real-World SOA
    Service-Oriented Architecture (SOA) is a current darling of the technical media. After reading all the SOA hype in technical magazines, papers, analyst reports, vendor literature, and weblogs, one might get the impression that with SOA, we've finally discovered the "silver bullet" that can magically solve all your IT problems. Our panelists are SOA veterans who, having deployed actual SOA-based production systems, will inject some reality into this picture, describing what about SOA really works and what doesn't work when it comes to real-world projects.

    The Globus Toolkit Ecosystem
    (and how to make it work for you)

    Matei Ripeanu (The University of Chicago) and
    Adriana Iamnitchi (Duke University)

    Abstract
    Grid computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation. The Globus Alliance is working to provide solutions to some of the most persistent and vexing problems that come up in Grid projects and applications. Solutions to date are collected in the Globus Toolkit and are used in many of today's major Grid infrastructures and applications.
    While the Globus Toolkit can make Grid projects and products significantly easier, the challenges themselves are far from easy and the Globus Toolkit does not provide a turnkey solution. Success in a Grid project depends on a clear vision of the problems that need to be solved, awareness of existing technologies that can contribute to the solutions (both within and beyond the Globus Toolkit), and a strategy for using the technology to overcome the challenge.
    This tutorial provides answers to critical questions for Grid project planners and product developers, including:

    The Globus Toolkit will be put into context, and examples and roadmaps for the most common uses of the Globus Toolkit will be provided.

    Who should attend?

    What you should already know:
    Attendees should be familiar with the basic principals of information technology. For example: general computer and network architecture, general software engineering processes, client/server systems, databases, current types of commercial IT products, basic internet concepts.

    What you will learn:
    Attendees will learn answers to the questions posed in the abstract above. In summary, attendees will gain a deeper understanding of how the Grid and the Globus Toolkit fit within their plans for producing useful products and/or applications and for planning successful Grid projects.

    Additional material will be available at: http://www.cs.uchicago.edu/~matei/GlobusEcosystem/

    Service Composition: Technologies, Methods and Tools for Synthesis and Orchestration of Composite Services and Processes

    Massimo Mecella and Giuseppe De Giacomo
    Universita' di Roma, La Sapienza

    INTENDED AUDIENCE: Researchers and Practitioners
    LENGTH: 3 hours

    The tutorial aims at providing a deep comprehension about the Service Composition problem, which is currently one the most hyped and addressed issue in the Service Oriented Computing. Starting from an analysis of current technologies and standards for Service composition (in particular for orchestration), the tutorial will lead the attendees to consider formal tools, such as logics of programs, which can be fruitfully considered for addressing the problem of (semi-)automatic composition synthesis. In the tutorial, attendees will consider:

    More in details, half of the tutorial will be spent on the first three items, whereas the following items will be considered in the latter half of the tutorial.

    Half-day Tutorial: Service Oriented Architectures and Semantic Web Processes

    Francisco Curbera (IBM),
    Amit Sheth and Kunal Verma (University of Georgia)

    The Web, the development of E-commerce, and new architectural concepts such as E-services and service oriented architectures (SOA) have created the basis for the emergence of a new networked economy. The scope of activities that business processes are expected to span has moved from intra-enterprise workflows coordinating multiple applications, to predefined inter-enterprise and B2B processes, and to dynamically defined Web processes among cooperating organizations. The importance of service annotation and dynamic discovery in E-services and SOA paradigms supports a parallel trend towards automatic inter-enterprise process integration. Components of technical aspect of the solutions involve the technologies for information exchange (from EDI to XML), software componentization (from CORBA to Web Services), and workflow coordination and collaboration. Semantics represents a new component to this mix, but it is also an integral part of its natural evolution. Semantics will provide a solid base for: a) rich service annotation and discovery, b) implementing scaleable architectures, and c) supporting the dramatically increasing dynamic nature of Web processes. While enterprises have sought to apply semantics to manage and exploit data or content, for example to support integration and analytics, the Web Processes are the way to exploit their applications, increasingly made interoperable as Web Services. Semantic Web Processes are semantics-enabled and empowered Web processes.
    This tutorial presents what can be achieved by symbiotic synthesis of two of the hottest R&D and technology application areas: Web services and the Semantic Web. It presents the more recent evolution of the Web service platform towards rich Web service and process model annotation, and explores some of the promises and challenges in applying semantics to each of the steps in the Semantic Web Process lifecycle. In particular, we present current Web services directions and the role of semantics in annotation (Semantic Annotation of Web Services), discovery (Semantic Web Service Discovery), composition (Semantic Process Composition), process execution/enactment (Semantic Web Process Orchestration), and quality of service of Semantic Web Processes. We will present examples of modeling real world business processes with Semantic Web technologies to highlight the benefits of using semantically rich data and process models as opposed to pure syntactic models. We also review ongoing frameworks and initiatives such as Semantic Web Service Initiative (SWSI) and OWL-S, efforts to extend Web Services related standards with Quality of Service (QoS) and semantics, as well as results from key projects such as the METEOR-S which build upon research, technology and current standards in workflow processes, Semantic Web, Web services and simulation.
