DEFINITION: Solution Specification ABB is a Business Object being embodied as a document of the highest possible level of granularity on an Solution Building Block, formulated as an agreed normative statement in design of an European Public Service. Source: ISO (https://www.iso.org/standard/40359.html) EXAMPLES: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): Semantic interoperability requirements concern also the specification of data formats, vocabularies and systems of identifiers that need to be supported to support interoperability within the EWShopp project. In addition, exploitation of the technology developed within the project outside the project consortium makes convenient to reuse whenever possible data formats, vocabularies and systems of identifiers that are the results of standardization efforts across Europe.
