4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
4.1 bounding box
portion of a coordinate space that lies between a lower bound and an upper bound in each dimension of a coordinate reference system
NOTE A bounding box can be used to express spatial-temporal query constraints, or to describe the
approximate location and extent of geospatial data. A bounding box is often called the minimum bounding rectangle of a geospatial data item when its lower and upper bounds in each dimension are those
of the data item.
EXAMPLES Rectangle in two spatial dimensions, rectangular solid in three spatial dimensions
4.2 capabilities XML
service metadata encoded in XML
4.3 client
software component that can invoke an operation from a server 4.4
geographic information information concerning phenomena implicitly or explicitly associated with a location
relative to the Earth [ISO 19128 draft]
4.5 interface
named set of operations that characterize the behaviour of an entity [ISO 19119]
4.6 operation

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
