Abstract

The Open Grid Services Architecture Data Movement Interface (OGSA-DMI) specification defines
a standardized mechanism for moving data from its source to its destination. By abstracting this
movement, the client complexity for moving data within a grid will be greatly reduced. OGSA-DMI
defines two port types for initiating, scheduling and managing data transfers from a given source
to a specified destination. The source and destination are described through Data End Point
References (DEPRs), a specialized form of a WS-Address.

An OGSA-DMI service will use the properties of the data to be transferred and the properties of
the infrastructure to decide what the best underlying transfer protocol to undertake the actual data
transfer is for the given combination of data source and sink. By this means OGSA-DMI provides
a common interface, though its abstraction layer, that can be used to span the preferred transfer
mechanisms used across many different types of Grid infrastructures.

This version of the specification aims to ensure that the OGSA-DMI port types are composable
with other Web Service (WS) specifications whilst being agnostic about any specific WS
rendering. OGSA-DMI is only concerned with the moving of data, i.e. bytes. Any associated
semantics are the responsibility of higher level services that leverage off OGSA-DMI. The OGSADMI
framework is general enough to cater for the movement of single elements of data or
composites.
