D2.2 Formal specification of the language (USDL XG Version)

The USDL version 3.0 milestone M5 has been released during the timespan of the Incubator group. Besides the constant smaller improvements that happen in every new milestone, M5 particularly added completely revised versions of the Service Level Module and Legal Module leading to the current modularization depicted in the figure below.

A further change worth mentioning is the introduction of a separate Technical Module which was basically split from the Functional Module. A complete specification for each module as well as an overview documentation was published in March 2011 and is available at www.internet-of-services.com.

A particular outcome of the incubator group has been a US-specific version of the Legal Module for input to future USDL version.
