WSDL is an XML Info set based document, which provides a model and XML format for describe web services. This enables services to be described and enables the client to consume these services in a standard way without knowing much on the lower level protocol exchange binding including SOAP and HTTP. This high level abstraction […]
SOAP is a simple and lightweight XML-based mechanism for creating structured data packages that can be exchanged between network applications. SOAP provides a simple enveloping mechanism and is proven in being able to work with existing networking services technologies such as HHTP. SOAP is also flexible and extensible. SOAP is based on the fact that […]

Identify the use cases that can drive the OGSA platform components. Identify and define the core OGSA platform components. Define hosting and platform specific bindings. Define resource models and resource profiles with interoperable solutions.
A service-oriented architecture is intended to define loosely coupled and interoperable services/applications, and to define a process for integrating these interoperable components.
DAS provides the following enhanced categories of accounting functionality to the IPG community: Allows a grid user to request access to a local resource via the presentation of grid credentials Determines and grants the appropriate authorizations for a user to access a local resource without requiring a preexisting account on the resource to govern local […]
Peer to Peer computing is a relatively new computing discipline in the realm of distributed computing. P2P system defines collaboration among a larger number of individuals and/or organizations, with a limited set of security requirements and a less complex resource-sharing topology.
The Open Grid Services Infrastructure (OGSI) was published by the Global Grid Forum (GGF) as a proposed recommendation in June 2003.[1] It was intended to provide an infrastructure layer for the Open Grid Services Architecture (OGSA). OGSI takes the statelessness issues (along with others) into account by essentially extending Web services to accommodate grid computing […]
Open Grid Services Architecture (OGSA) is a set of standards defining the way in which information is shared among diverse components of large, heterogeneous grid systems. In this context, a grid system is a scalable wide area network (WAN) that supports resource sharing and distribution. OGSA is a trademark of the Open Grid Forum.
