Digital Library and Data Grid Technology Group

Authors: Reagan W. Moore

Abstract
Digital libraries and data grids manage state information about data collections. This is in contrast to the management of semantic information used for discovery that is provided by semantic web technology. The discussion group investigated the types of inferences and relationship management that would improve digital library and grid services. Notable examples include management of relationships discovered by data mining services, management of properties associated with grid name spaces, and management of properties associated with encoding format structure descriptions.

Modeling Services for the Semantic Grid

Authors: Axel Polleres, Ioan Toma, and Dieter Fensel

Abstract
The Grid has emerged as a new distributed computing infrastructure for ad- vanced science and engineering aiming at enabling sharing of resources and infor- mation towards coordinated problem solving in dynamic environments. Research in Grid Computing and Web Services has recently converged in what is known as the Web Service Resource Framework. While Web Service technologies and standards such as SOAP and WSDL provide the syntactical basis for communi- cation in this framework, a service oriented grid architecture for communication has been defined in the Open Grid Service architecture. Wide agreement that a flexible service Grid is not possible without support by Semantic technologies has lead to the term "Semantic Grid" which is at the moment only vaguely defined. In our ongoing work on the Web Service Modeling Ontology (WSMO) we so far concentrated on the semantic description of Web services with respect to applications in Enterprise Application Integration and B2B integration sce- narios. Although the typical application areas of Semantic Web services have slightly different requirements than the typical application scenarios in the Grid a big overlap justifies the assumption that most research results in the Semantic Web Services area can be similarly applied in the Semantic Grid. The present abstract summarizes the authors view on how to fruitfully in- tegrate Semantic Web service technologies around WSMO/WSML and WSMX and Grid technologies in a Semantic Service Grid and gives an outlook on further possible directions and research. The reminder of this abstract is structured as follows. After giving a short overview of the current Grid Service architecture and its particular requirements, we shortly review the basic usage tasks for Semantic Web services. We then point out how these crucial tasks of Semantic Web services are to be addressed by WSMO. In turn, we try to analyze which special requirements for Semantic Web Services arise with respect to the Grid. We conclude by giving an outlook on the limitations of current Semantic Web services technologies and how we plan to address these in the future in a common Framework for Semantic Grid services.

Negotiating Trust on the Grid

Authors: Jim Basney, Wolfgang Nejdl, Daniel Olmedilla, Von Welch, and Marianne Winslett

Abstract
Grids support dynamically evolving collections of resources and users, usually spanning multiple administrative domains. The dynamic and crossorganizational aspects of Grids introduce challenging management and policy issues for controlling access to Grid resources. In this paper we show how to extend the Grid Security Infrastructure to provide better support for the dynamic and cross-organizational aspects of Grid activities, by adding facilities for dynamic establishment of trust between parties. We present the PeerTrust language for access control policies, which is based on guarded distributed logic programs, and show how to use PeerTrust to model common Grid trust needs.

ODESGS, an Environment for the Annotation and Design of Grid Environments

Authors: Asuncion Gomez-Perez and Rafael González-Cabero

Abstract
ODESGS is an ongoing work carried out in the Ontogrid Project (FP6-511513). It is the extension of the ODESWS Environment [1] developed in the context of the Esperonto Project (IST-2001-34372) and is an implementation of the ODESGS Framework [2]. This framework is being developed for the markup of Grid Services (GS) and creation of new complex Semantic Grid Services (SGS) from these annotated GS, to enable their discovery and (semi)automatic composition. It also formalizes Virtual Organizations (VO) with it, defined, since the appearance of OGSA, as a set of the services that are operated and shared. Therefore, VO description is closely attached to the descriptions made to each GS individually, plus additional information about the relationships and policies between these services. Note that what we mean as markup of VO and SGS is the association of these elements with an instance of the ODESGS Ontology.

Ontology Access Provisioning in Grid Environments

Authors: Miguel Esteban Gutiérrez and Asuncion Gomez-Perez

Abstract
The increase of use of semantic technologies has reached almost every computer science related field, including the grid computing field . The next generation Grid should virtualise the notion of distribution in computation, storage, and communication over unlimited resources with well defined computational semantics. A Grid node may provide new services, functions or even new concepts that are unknown to clients. The semantics of such services are defined by means of Ontologies [Gruber, 1993; Gómez-Pérez et al., 2003]. Thus providing the appropriate means for accessing and using Ontologies in the Grid is fundamental if semantic technologies are to be used. So, the transition from monolithic, centralized ontology services to a virtual organization of Grid compliant and Grid aware ontology services that can coordinate and cooperate with each other is crucial to progress towards the Semantic Grid [De Roure et al., 2005].

Scientific Workflows: Catalyzing the Grid ⇌ Semantic Web Reaction

Authors: Bertram Ludaescher

Abstract
Scientific workflows allow scientists to automate repetitive data management, analysis, and visualization tasks, and to document the provenance of analysis results. Scientific workflows are composed of interlinked computational components (sometimes called actors), and the datasets that are consumed and produced by those components. Scientific workflow systems are problem-solving environments to design, reuse, share, execute, monitor, and archive scientific workflows. As such, they are the primary tool that end user scientists use when interacting with the emerging e-Science cyberinfrastucture. Scientific workflow systems can often benefit from both, Grid and Semantic Web capabilities. Thus, scientific workflows can bring together these otherwise loosely connected technologies and "catalyze the reaction" between them.

Security and Trust Issues in Semantic Grids

Authors: Daniel Olmedilla, Omer F. Rana, Brian Matthews, and Wolfgang Nejdl

Abstract
Grid computing allows sharing of services and resources accross institutions. However, current Grid security mechanisms for authentication and authorization are too rigid and they lack the ability to determine how ``trustworthy'' the result obtained from a specific provider is likely to be. This paper describes the different facets associated to Trust and identifies the need for Trust Management approaches in the context of Virtual Organizations lifecycle and resource access control in the Grid.

Semantic Grid Roadmap

Authors: Ziga Turk

Abstract
Conclusion: While the first level of information systems was built to assist humans in real world processes, the increasing complexity of the ITC infrastructures calls for a second level of information systems that will assist in making a better use of ITC. All business process roadmaps are foreseeing a strong role of ICT in the future. Semantic grid has a potential to be a highway in these roadmaps or a dead end into which substantial effort will be placed, but that will not address the needs of the users. We will not know, unless we try it out, looking carefully at the technology pull in some areas and applying the technology push if a breakthrough seems possible.

Semantic Technologies in the SIMDAT Grid Project

Authors: Juergen Angele and Moritz Weiten

Abstract
The SIMDAT project aims at developing generic grid technology for the solution of complex application problems and using this new technology in several industrial application sectors. Semantic technologies are expected to offer a significant added value to other technologies with respect to the management of resources on the process level and on the data level. The strategic objectives of SIMDAT are (i) to test and enhance data grid technology for product development and production process design, (ii) to develop federated versions of problem-solving environments (PSEs) by leveraging enhanced grid services, (iii) to exploit data grids as a basis for distributed knowledge discovery, (iv) to promote de facto standards for these enhanced grid technologies across a range of disciplines and sectors as well as (v) to raise awareness for the advantages of data grids in important industrial sectors.

The Adaptable Viral Archive

Authors: Bruce R. Barkstrom

Abstract
In this paper, the author considers how semantic technologies may impact the design of future archives, which require both very secure approaches to maintaining data, metadata, and their provenance, as well as the most cost effective operation possible. One potential application for semantic technologies may be improving the automation of system configuration, allowing an archive to be ``self-replicating'' or ``viral'' – meaning that the archive infrastructure as well as its data could automatically pack itself into a self-contained structure that could be transmitted to a new site and automatically unpack itself. A more challenging problem is likely to be dealing with the evolution of the semantics of the collection and of the archive's user communities over an extended period of time.

Towards a Semantic Grid Architecture

Authors: Carole Goble

Abstract
The Semantic Grid is an extension of the current Grid in which information and services are given well defined and explicitly represented meaning, better enabling computers and people to work in cooperation. In the last few years, several projects have embraced this vision and there are already successful pioneering applications that combine the strengths of the Grid and of semantic technologies. However, the Semantic Grid currently lacks a reference architecture, or a systematic approach for designing Semantic Grid components or applications. We need a Reference Semantic Grid Architecture that extends the Open Grid Services Architecture by explicitly defining the mechanisms that will allow for the explicit use of semantics and the associated knowledge to support a spectrum of service capabilities. An architecture would have (at least) three major components which are depicted in the extended abstract.

Towards Mapping-Based Document Retrieval in Heterogeneous Digital Libraries

Authors: Heiner Stuckenschmidt, Wolf Siberski, and Erik van Mulligen

Abstract
In many scientific domains, researchers depend on a timely and efficient access to available publications in their particular area. The increasing availability of publications in electronic form via digital libraries is a reaction to this need. A remaining problem is the fact that the pool of all available publications is distributed between different libraries. In order to increase the availability of information, these different libraries should be linked in such a way, that all the information is available via any one of them. Peer-to-peer technologies provide sophisticated solutions for this kind of loose integration of information sources. In our work, we consider digital libraries that organize documents according to a dedicated classification hierarchy or provide access to information on the basis of a thesaurus. These kinds of access mechanisms have proven to increase the retrieval result and are therefore widely used. On the other hand, this causes new problems as different sources will use different classifications and thesauri to organize information. This means, that we have to be able to mediate between these different structures. Integrating this mediation into the information retrieval process is a problem that to the best of our knowledge has not been addressed before.

What can the Semantic Grid do for Science and Engineering?

Authors: James D. Myers

Abstract
Scientists and Engineers have been happily performing research and Analyses for hundreds of years without the Semantic Grid. What’s changing in their world now that would motivate them to look to the Semantic Grid? Which of their problems can it solve? And how can we recognize the low-hanging fruit – the combinations of communities and issues where introducing the Semantic grid now will create the most scientific value? Traditional science is being done faster and community-level discovery-based science and systems approaches are emerging. Semantic Grid technologies can provide a critical capability to reuse data, software, and services while evolving the underlying grid and science models involved. While not often mentioned by name, SG technologies – exposing and reasoning over model-level descriptions of resources within and on the Grid – are directly relevant to problems of managing large amounts of heterogeneous data in a fluid scientific and technological environment. This presentation will attempt to map between language of science and that of grids and the semantic web to identify use cases where deploying a "Semantic Grid" could have significant scientific value.
