>From the OASIS SOA Reference Model (pertaining to services at time of
execution) (01)
"720 The execution context of a service interaction is the set of
infrastructure elements, process
721 entities, policy assertions and agreements that are identified as part
of an instantiated service
722 interaction, and thus forms a path between those with needs and those
with capabilities." (02)
This could perhaps be paraphrased as ³the set of [circumstances] surrounding
and having a modifying effect towards a concept or thing (or an instance
thereof??)² (03)
A lot more has been written on the subject of context in the reference model
and we strove to define this concept in the context of services. (04)
"723 As discussed in previous sections of this document, the service
description (and a corresponding
724 description associated with the service consumer and its needs) contains
information that can
725 include preferred protocols, semantics, policies and other conditions
and assumptions that" (05)
