What have I told you?
• Use of standards (O&M, WaterML) requires specific vocabularies (observable properties, instruments, algorithms)
• The vocabularies can be structured using existing models (QUDT, SKOS) and link to existing vocabularies (ChEBI, QUDT, SWEET)
• Publish as fine-grained linked-data to make reusable • Transparent lifecycle to make trusted
