Open Grid Services Architecture
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 2002 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 a Web services architecture, specifically designed to support grid requirements. The concept of OGSA is derived from work presented in the 2002 Globus Alliance paper "The Physiology of the Grid" by Ian Foster, Carl Kesselman, Jeffrey M. Nick, and Steven Tuecke. It was developed by GGF working groups which resulted in a document, entitled The Open Grid Services Architecture, Version 1.5 in 2006. The GGF published some use case scenarios.

Stigmata
by: WeeksWell I met the man who killed my mother
He put holes inside her arms
No they were not marks of stigmata lord
Just a drug pumping empty heart
Well I met the man who took my father
Put him in jail and locked him away
Well they say he forgot his children lord
He might remember us again someday
I blame the devil
Well I met the man who killed my grandmother
He took her mind as the shotgun blew
A year later my grandfather followed her
He’d had enough and shot himself too
Well I met the man who took my good friend
Oh, but he was only seventeen
I saw him laying in a cushioned coffin lord
It wasn’t him staring back at me
I blame the devil, what else could it be
I blame Jesus he ain't answering me
Don’t call me depressed, don’t call me sad
I’m giving up on this life I had
Well I met the man who raped my childhood
Oh well we were never young it’s true
But when everyone around you keeps dying lord
What the hell are we supposed to do
Well I met the man who took my sister
In a new family she will stay
And it’s true that my mother’s a sinner lord
She let another family fade away
I blame the devil, what else could it be
I blame Jesus he ain't answering me
Don’t call me depressed, don’t call me sad
