Project• Kick off 14/05/09• Scope

– HoGent datamodel for PURE 4.– Funding model– Geographical coverage– Validator business rules

• Partners– EWI– Collibra

• Deliverables – Adapted “Collibra Platform” with CERIF output– The models (syntax, semantics including business rules)– EWI collaborators trained– Target date 14/10/2009

• Usage of products– Drive ingest validator from the semantics– Provide generic base model with agreed semantics to stakeholders
