4.8 platform
the underlying infrastructure in a distributed system Adapted from ISO 19119
NOTE A platform describes the hardware and software components used in a distributed system. To
achieve interoperability, an infrastructure that allows the components of a distributed system to interoperate is needed. This infrastructure, which may be provided by a Distributed Computing Platform DCP, allows
objects to interoperate across computer networks, hardware platforms, operating systems and programming languages. Adapted from Subclause 10.1 of ISO 19119
4.9 platform-neutral specification
independent of a specific platform Adapted from ISO 19119
NOTE It is assumed that one platform-neutral service specification will be the basis for multiple
platform-specific service specifications. Multiple platform-specific specifications are necessary because of the variety of DCPs and the differences in the way in which they support the functional requirements. One
platform-neutral service specification is needed to support interoperability of multiple platform-specific specifications. Adapted from Subclause 10.2 of ISO 19119
4.10 platform-specific specification
dependent on a specific platform Adapted from ISO 19119
