Web 2.0: Social Networking for MSI Researchers
Marlon Pierce We present our work on using Web 2.0 to build a social networking portal for researchers at Minority Serving Institutions. The key feature of our work is to use social bookmarking and tagging as a means for building up user profiles that can be subsequently searched and used for matchmaking, enabling users to identify others with complementary research interests. We describe our system architecture and provide a survey and comparison of various Web 2.0 tools for building rich client interfaces and backend services for managing bookmarks.

Web 2.0 - a path to wider uptake of e-Research?
Alex Voss, National Centre for e-Social Science This talk will explore the potential of Web 2.0 to foster wider uptake of e-Research. Adoption of e-Research is driven both by the development of outstanding examples of the potential of technologies (capability) and the development of easily accessible versions that allow people to experience technologies themselves without major investments (capacity). The challenge is to develop ways to move into the space between these two extremes and create beaten paths for researchers to develop increasingly sophisticated ways of using advanced information technologies in their research. This talk will explore the role that of Web 2.0 in this as well as the relation between Web 2.0 and Grid technologies.

Web 2.0 Grids and Cyberinfrastructure
Geoffrey Fox Discussion of integration of Grid workflow, Web 2.0 Mashups and Parallel Computing into Cyberinfrastructure. We present examples of a model for high performance scientific applications where the Parallel Computing Productivity layer (coarse grain functional parallelism) is integrated by Workflow or Mashups (including Yahoo Pipes or Google MapReduce) with the classic MPI style parallelism encapsulated in services and produced by "experts". The system is implemented on Windows with the Microsoft CCR and DSS software offering support for fine grain and coarse grain (service) synchronization. We give an example from the GIS domain with parallelism implemented on multicore chips. Agenda: Discussion of work at Community Grids Laboratory ( Geoffrey Fox, Xiaohong Qiu, Huapeng Yuan, Seung-Hee Bae) and Microsoft (George Chrysanthakopoulos, Henrik Frystyk Nielsen)

Real-time Web 2.0: Evolution of Middleware for Grid-based Instruments and Sensors
Donald F. (Rick) McMullen, Marlon Pierce, Carol Deng, Kia Huffman

Instruments and sensors provide observational data needed to drive the engine of discovery in science. Availability and accessibility of appropriate instrumentation for a given research programme can be a rate limiting factor in discovery. Furthermore sensors and sensor networks are playing an ever-increasing role in longitudinal studies in ecological, earth and biological sciences. The Common Instrument Middleware Architecture (CIMA) is a means of improving accessibility and usability of critical research resources, and provides application-level access to remote instruments and sensors through interface and protocol standards based on Web Services and a Service Oriented Architecture (SOA) approach.

As a counterpoint to Web Services (but not SOA), Web 2.0 technologies show great promise for increasing the diversity and rate of production of new services as well as the accessibility and reuse of existing services. In this paper we discuss the impact of Web 2.0 technologies and applications on the evolution of the CIMA architecture and the design of RESTful services for instruments, sensors and other real-time data sources.

The Web, HPC and UNICORE
slides in HTML
R. Menday, B. Hagemeier, A. Streit

UNICORE is an established Grid platform providing access to distributed computational resources, particularly HPC resources. Over the past 10 years we have seen UNICORE in production usage at many supercomputer centres and used in many projects. In summer 2007 the final version of the WS-RF compliant, OGSA based UNICORE 6 [1] is released. Building on the core values of UNICORE - "seamless, intuitive and secure access" - in this OGF session we propose to explore the opportunities from closely aligning the Grid and the Web to build a newthe next generation of UNICORE. We intend to give an introduction to the key concepts and a short demonstration of a proof of concept implementation during the session.

This deep integration leads to the embedding of the Grid into the larger Web (more precisely the Semantic Web). As such the Web can be seen as the global, homogenizing middleware layer for the Grid. A RESTful use of HTTP and a unified model for the information of the Grid, result in a loosely-coupled and internet-scale architecture. Each grouping of computational resources (normally aligned with administrative boundaries) have a projection onto the Web. The URI space for a single site is partitioned according to the resources in the site, maintaining a single point of access and the virtualisation of these resources. Viewed from a global perspective, this proposed new UNICORE Grid consists of a distribution of Grid Web sites.

We take a resource-oriented approach where each significant resource (Sites, Users, Files, Jobs, etc) are named with HTTP URIs, and from which various representations can be obtained (RDF, JSON, HTML). Following the recommendations of LinkingOpenData [21] initiative this information about the Grid of computational resources adds to the Web of Data. Resource and data management is performed through the manipulation of this information. Knowledge representation offered by the Semantic Web stack of technologies provides the basis for additional information to be attached to the resources of the Grid. For example, 'tagging' items in the Grid and publishing other additional domain-specific data, and this is a basis for the participatory Grid, offering for example, the selected sharing of jobs and data. Other sites perform an aggregating role (similar to Google search or Yahoo pipes) providing users with a high-level view of their distributed resources and tools to interact with them. For example, searching functionality across this information using the Semantic Web query language SPARQL, providing virtualised views over distributed data, and finally visualisation using timelines and maps.

Web 2.0 technology and Semantic Research Grid (SRG)
Geoffrey Fox, Ahmet Fatih Mustacoglu, Ahmet E. Topcu We describe an ongoing project having a integrated system that consists of tools and services for supporting Cyberinfrastructure based scientific research.This system, called the Semantic Research Grid (SRG) provides to use existing online annotation and search tools in order to develop added-value community-building tools that leverage the semantic analysis of digital documents.Also, we describe event-based consistency model and discuss the implementation and integration of this model in SRG.So, we discuss the design, the overall architecture,and the current state of the implementation of SRG using web 2.0 capabilities and provide a roadmap of the future work in this project.

Geoffrey Fox, Lee Dirks We describe work to build a service-based cyberinfrastructure to support chemical informatics. Indiana University, with funding from the US National Institutes of Health, has built a Web services-based grid that provides a wide range of capabilities to support problems in chemical docking and screening assay analysis. Although not initially designed with Web 2.0 principles in mind, the project has gravitated towards these approaches. We conclude with a summary of future work, which will investigate the overlap of chemistry data services and workflows with concepts from the Digital Libraries community. This work will involve the development of Web 2.0 compatible repository services and composite metadata objects.

Web 2.0 infrastructure and applications
slides in PDF
Savas Parastatidis

Only few companies or organizations in the world have the data and computational infrastructure to support the contemporary needs of researchers. Collaboration, data/information/knowledge sharing and discovery, archiving, large-scale computation, etc. are only few of the requirements a modern research platform should support. Is it feasible for research organizations to maintain their own research infrastructure; is a paradigm shift necessary?

The Web has evolved from a distributed information systems for the presentation of information to a large-scale application platform. Modern applications exist on the Web, they combine data and functionality from distributed sources, and they bring people together in domain-specific social networks. Are traditional middleware platforms a thing of the past and is the outsourcing of infrastructure/services becoming a necessity?

The Future of Web 2.0 at OGF Geoffrey Fox and David De Roure Wrapup discussion.
SciVee Presentation in Grid and Web 2.0 We regret that this talk has been cancelled Phil Bourne

Today's graduate students belong to the YouTube generation. They are already authors on papers and will be tomorrow's leading scientists. In short, we are on the verge of having a new generation of scientists who are comfortable with and utilize the short video clip and the tools that go with them e.g., iPods. Publishers and the community at large have been slow to take advantage of this phenomenon

With open access publications from the Public Library of Science (PLoS) and later with abstracts of closed access publications we will provide a Web resource for authors to upload up to a ten minute video clip which provides a synopsis of the work presented in a published peer review paper. The clip will be expected to briefly introduce the motivation for the work, present the experiment the most salient results and a brief conclusion. This is similar to an extended abstract, but using a different medium and akin to the short talk formats offered at some conferences. We refer to these as SciVees and each journal represented constitutes a channel. Communities represent other multimedia materials not directly tied to a peer reviewed publication. Surfing through SciVee is intended to be like other broadcast media which ranges from high quality Public Broadcasting channels for smaller audiences to more popular material for broad consumption. We hope that scientific research and education will benefit from this endeavor.

This event is organised by the Semantic Grid Group (SEM-RG) in OGF in conjunction with the Humanities, Arts, and Social Sciences RG Group (HASS-RG), both part of the OGF eScience function.
