==Description==
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 is based on several other [[Web service]] technologies, such as the [[Web Services Description Language]] (WSDL) and the [[Simple Object Access Protocol]] (SOAP), but it aims to be largely independent of transport-level handling of data.
OGSA has been described as a refinement of a Web services architecture, specifically designed to support grid requirements.<ref>[http://www.nesc.ac.uk/teams/OGSAanalysisDennisGannon.pdf An Analysis of The Open Grid Services Architecture]{{Dead link|date=August 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
The concept of OGSA is derived from work presented in the 2002 [[Globus Alliance]] paper "The Physiology of the Grid" by [[Ian Foster (computer scientist)|Ian Foster]], [[Carl Kesselman]], Jeffrey M. Nick, and Steven Tuecke.<ref>{{Cite web |title= The Physiology of the Grid: An Open Grid Services Architecture for Distributed Systems Integration |author= [[Ian Foster (computer scientist)|Ian Foster]], [[Carl Kesselman]], Jeffrey M.

It was developed by GGF working groups which resulted in a document, entitled ''The Open Grid Services Architecture, Version 1.5'' in 2006.<ref name="GFD80">{{Cite web |author= |date=24 July 2006 |editor-last=Foster |editor-first=I. |editor2-last=Kishimoto |editor2-first=H. |editor3-last=Savva |editor3-first=A. |title=The Open Grid Services Architecture, Version 1.5 |url=http://www.ogf.org/documents/GFD.80.pdf |accessdate=28 July 2013 |publisher=Open Grid Forum}}</ref>
The GGF published some use case scenarios.<ref>[http://www.ogf.org/documents/GFD.29.pdf OGSA Tier 1 Use Case Draft Document]</ref>
