'''Open Grid Services Architecture''' ('''OGSA''') describes a [[service-oriented architecture]] for a [[grid computing]] environment for business and scientific use.

It was developed within the [[Open Grid Forum]], which was called the Global Grid Forum (GGF) at the time, around 2004 to 2006.

==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 the emerging 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]</ref>
OGSA has beenwas 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 [[Global Grid Forum|GGF]] working groups which resulted in a GGF information document, entitled ''The Open Grid Services Architecture, Version 1.5'' in 2006.<ref name="GFD80">[http://www.ogf.org/documents/GFD.80.pdf{{Cite web |title= The Open Grid Services Architecture, Version 1.5]</ref> The|author= [[GlobalIan GridFoster, Forum]]H. continuesKishimoto, toand trackA.
