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:
“Don: Why are they closed? They’re all closed, every one of them.
Pawnbroker: Sure they are. It’s Yom Kippur.
Don: It’s what?
Pawnbroker: It’s Yom Kippur, a Jewish holiday.
Don: It is? So what about Kelly’s and Gallagher’s?
Pawnbroker: They’re closed, too. We’ve got an agreement. They keep closed on Yom Kippur and we don’t open on St. Patrick’s.”
—Billy Wilder (b. 1906)
“The community and family networks which helped sustain earlier generations have become scarcer for growing numbers of young parents. Those who lack links to these traditional sources of support are hard-pressed to find other resources, given the emphasis in our society on providing treatment services, rather than preventive services and support for health maintenance and well-being.”
—Bernice Weissbourd (20th century)
“They can do without architecture who have no olives nor wines in the cellar.”
—Henry David Thoreau (1817–1862)
