Open Grid Services Architecture (OGSA) describes an architecture for a service-oriented grid computing environment for business and scientific use, developed within the Global Grid Forum (GGF). OGSA is based on several other Web service technologies, notably WSDL and SOAP, but it aims to be largely agnostic in relation to the transport-level handling of data.
Briefly, OGSA is a distributed interaction and computing architecture based around services, assuring interoperability on heterogeneous systems so that different types of resources can communicate and share information. OGSA has been described as a refinement of the emerging Web Services architecture, specifically designed to support Grid requirements. OGSA has been adopted as a grid architecture by a number of grid projects including the Globus Alliance. Conceptually, OGSA was first suggested in a seminal paper by Ian Foster called "The Physiology of the Grid", and later developed by GGF working groups which resulted in a GGF information document, entitled The Open Grid Services Architecture, Version 1.5. The Global Grid Forum continues to track Tier 1 use case scenarios used in the definition of the OGSA core services.

Famous quotes containing the words open, services and/or architecture:
“Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.”
—Sydney J. Harris (1917–1986)
“Working women today are trying to achieve in the work world what men have achieved all along—but men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its toll—on women, on men, and on our children.”
—Jeanne Elium (20th century)
“All architecture is great architecture after sunset; perhaps architecture is really a nocturnal art, like the art of fireworks.”
—Gilbert Keith Chesterton (1874–1936)
