This section includes the high-level semantic requirements derived from the use-cases. The semantic requirements provide a framework for a detailed description of services in the architecture section. This section presents the derived requirements, as a result of the requirements analysis of the use cases presented in previous section.

The following is summary of the sub-sections:

The analysis includes tracing of requirements up to the use case and stakeholders and down to service capabilities specified later in this document. Note that the requirements section is not complete and this section is expected to evolve as additional requirements are added.
