A major promise of DIDO is the ability to use machines to automatically process data and transactions rather than to rely on humans “in the middle.” A key to automating many of these processes is realized through the adoption of the semantic web. In essence, the semantic web is the institutional memory and experience captured in machine readable form and available at each node. This eliminates the centralized human-centric requirements of the past and supports a distributed, automated solution. The semantic web uses formal semantics that unambiguously capture the vocabulary and ontology of the domain.
