It is difficult for enterprise to build CAS (content addressable storage) appliance system because the most of CAS systems only provide API interface, to design and implement a new kind of CAS storage system is proposed in this paper. CAS interface based on http is suggested, which will turn the operation of file objects into the WEB semantic operation of URI resources, so that the management and...
Wikis are used by many projects as part of a collaboration platform. Yet, they have not been adopted by the majority of researchers for creating permanent scientific output. In this paper we try to overcome the shortcomings of Wikis by replacing their persistence layer by a digital object repository. Our solution, which combines JSPWiki and Fedora, provides automatic provenance metadata, assigns persistent...
FSP, short for foundation software platform, refers to the supporting foundation of application system. Third-party integration testing is the important method to ensure the quality of FSP. The integration testing of FSP would involve collaboration among many vendors, cover functionality testing, compatibility testing, performance testing etc. Furthermore, foundation software usually has very huge...
The paper explores the new model of Information resource sharing of Personal Digital Library by using such methods as the systems analysis and design and the simulation. Through the technology such as the P2P, metadata and database, it aims to construct the PDL resource sharing platform to implement the effective information resource sharing of PDL in the certain sharing scope such as academic society,...
In order to implement the sharing of remote sensing data over the Internet, we proposed an original approach to acquire and integrate remote sensing image metadata using grid service. Firstly, we encapsulated the metadata extracting algorithms and metadata retrieving algorithms into grid services, which can be called on the Web with SOAP messages; secondly, a grid service registry that enables the...
In high performance computing environment, the metadata servers of distributed file system become critical to impact overall system performance. An approach of memory based metadata server is proposed, instead of the disk based approach. We present a metadata management system with matrix organization, non-overhead reliable mechanism and static scalability method, which is design to efficiently utilize...
Metadata management is a key technology of heterogeneous data sources integration. Metadata management in data grid is based on distributed multi-layer mapping on resources, which has the characteristics of centralization in indexing and decentralization in resources. These characteristics may lead multiple request redirections in the relevant resource search process and eventually increase the cost...
