The key innovation of the Brokering
approach is the change in paradigm: rather than building interoperability by requiring the
agreement on a single set of standards, which in a complex multidisciplinary environments
does not work, the Brokering middleware allows each system to stay as is, and builds
bridges, or mediates, between them allowing to search and access data across them all
(Nativi et al. 2012, and 2013).
