ONION Ontologies In Ontology Community of Practice Leader

2 ONION Ontologies In Ontology ePowerAssist What is “Ontologies In Ontology” ONION is an open source semantic reference tool for the business of information technology (many terms have novel or dual meanings) ONION is structured as a Community of Practice (COP) ontology that has multiple, domain specific, layers. The content of each layer is scoped by the set of IT topics that are relevant to a particular Community of Interest (COI) or Community of Action (COA). Foundational layers of the ONION are aligned with the public specifications of: IT Service Management Best Practice; IT Control Frameworks; Information Security; IT Auditor Control Objectives ; and Service Oriented Architecture (SOA). Classification schema(s), the ONION core uses explicit links to controlled vocabularies as they become publicly available: Especially, those for IT Infrastructure (classes, properties, methods, values) and Open Source Components (XML elements, attributes)
