Data management
Multiple data producers (12 competent authorities, 6 water agencies, 4 specialised institutes, 150 laboratories, ... )
Multiple data bases
Common uses -> needs for• interoperability• reliability• comparability• sustainability
Solved by a common reference framework (« Sandre » framework)

Common reference framework
• Extensive data dictionaries and data models
• Reference datasets
• Data exchange formats: EDI frames then XML
• Metadata: business md, then regular ISO 19115
• Data services: for reference datasets (web services: SOAP, REST) and monitoring results (2007)

Data dictionary
What is a “sample” ?
Conceptual interoperability (or human interoperability)
At discursive level:
• Definition • Rules and constraints on participating processes and actors• Components

Data model
From discursive to formal level: • conceptual diagram (or UML class diagram)• does not capture everything
then • XML schema for exchange scenario
syntactic interoperability (or human aided machine interoperability: allows for a common data repository)
then • Web services (with XML payload)

Quality assurance & control
• Accreditation (ISO 17025) of laboratories is mandatory, including inter-lab comparisons
• By the French accreditation body or any European equivalent body
• Extended accreditation audits check additional requirements (LoQ, ...) from FR/EU regulations
• Analyses must be done under the accreditation conditions
• Analytic performances and traceability of results are implemented in the data exchange scenario
