SRG: A Digital Document-Enhanced Service Oriented Research Grid

Abstract

Abstract-We describe an ongoing project building a system that consists of tools and services for supporting Cyberinfrastructure based scientific research. This system, called the Semantic Research Grid (SRG), integrates a number of existing online research tools (social bookmarking, academic search, scientific databases, journal and conference content management systems) and aims to develop added-value community-building tools that leverage the semantic analysis of digital documents. We discuss the design, the overall architecture, and the current state of the implementation of SRG, and provide a roadmap of the future work in this project.

Hybrid consistency framework for distributed annotation records in a collaborative environment

“…Moreover, they are independent systems and we cannot lock them during the update executions to prevent inconsistencies. [20]. In the second and third cases; data manager process the request with the lowest timestamp first according to our concurrent updates policy.…”

“…Our model, works around these Web 2.0 tools to reconcile DARs from each annotation tool in a consistent way. In the current implemented version, we have integrated Delicious, Citeulike, and Connotea into our prototype system called Semantic Research Grid (SRG) [20].…”

“…In our proposed solution, we keep primary copy of each DAR with extra metadata fields in our relational database, where the primary copy of each DAR can be collaborated and updated consistently, and we provide a hybrid consistency framework to maintain consistency between all replicas of DARs stored at various annotation tools and a primary copy of each DAR. This paper discusses the hybrid consistency framework for the replicas of the same DARs maintained at different annotation tools and expounds its implementation and integration with Semantic Research Grid [20] system. The rest of this paper is organized as follows: Section 2 provides a discussion of the consistency criteria.…”

Performance of a collaborative framework for federating distributed digital entities

“…As these services enable storing, tagging and sharing documents, another emerging need has also appeared for supporting these tools by using their existing services via Web Service wrappers with added capabilities. In our Internet Documentation and Integration of Metadata (IDIOM) framework [9][10][11][12][13][14], we are able to manage, share and reconcile scholarly publications that are stored in several social bookmarking tools in a Service Oriented Architecture where communications are provided through the Web Service technology [15]. The IDIOM software is available from [16].…”

“…Figure 1 illustrates the architecture of the IDIOM system. This paper investigates the performance and the scalability results of the event-based infrastructure and consistency maintenance parts of the IDIOM system [9][10][11][12][13][14] that federates online digital entities. The rest of this paper is organized as follows: Section 2 provides background information on event-based systems and consistency mechanisms.…”
