Okkam synapsis: a community-driven hub for sharing and reusing mappings across vocabularies

In the past 10-15 years, a large amount of resources have been devoted to develop highly sophisticated and effective tools for automated and semi-automated schema-vocabulary-ontology matching and alignment. However, very little effort has been made to consolidate the outputs, in particular to share the resulting mappings with the community of researchers and practitioners, support a community-driven revision/ evaluation of mappings and make them reusable. Yet, mappings are an extremely valuable asset, as they provide an integration map for the web of data and the "glue" for the Global Giant Graph envisaged by Tim Berners-Lee. Aiming at kicking-off a positive endeavor, we have developed Synapsis, a platform to support a community-driven lifecycle of contextual mappings across ontologies, vocabularies and schemas. Okkam Synapsis offers utilities to load, create, maintain, comment, subscribe, and define levels of agreement over user defined contextual mappings available also through REST ...
