The Simple API for Grid Applications (SAGA), is an open standard defined and maintained by the Open Grid Forum that describes an interface for high-level Grid application programming.

Scope
The SAGA API does not strive to replace Globus or similar Grid middleware systems, and does not target middleware developers, but solely application developers with no assumed background on Grid Computing who wish to Grid enable their applications whilst spending as little time as possible learning new paradigms. Such developers typically wish to devote their time to their own goals and minimize the time spent coding infrastructure functionality. The API insulates application developers from middleware. The specification of services, and the protocols to interact with them, is out of the scope of SAGA. Rather, the API seeks to hide the detail of any service infrastructures that may or may not be used to implement the functionality that the application developer needs. The API alignes, however, with all middleware standards within OGF. The SAGA API is designed to be extensible: a well defined mechanism exists to specify additional API packages which expand the scope of the API as needed. The SAGA Core API itself defines a number of packages: job management, file management, replica management, remote procedure calls, and streams. A large part of the SAGA Core API specification
Standardization
SAGA is being standardized by the Open Grid Forum. In fact, SAGA is ultimately a set of OGF standard documents.
- The SAGA Core API Specification is the base of that set of standards, and defines the Look and Feel of the SAGA API.
