[OPTIONAL, one]

Technical Definition:

Potential high level issues in implementing a service implementation or in using a service implementation designed from a service expression specialised from the Service Genre. Are there high level assumptions about design, middleware, data structures, behaviours, etc., that are not described elsewhere? Are there any implementation- or deployment-specific considerations (e.g., technology dependencies)?

Commentary:

The IMPLEMENTATION GUIDE is a discussion of high-level issues that may affect the development or use of implementations based on the Service Genre, including any assumptions about the design or technology DEPENDENCIES. Whenever possible, implementation decisions and choices should be deferred to the service implementation design.
