ProblemProblem

• “Citizen Science Observations” – interoperability thereof• What does interoperability actually mean?

– And is it the same for all stakeholders?

• Current best practices:– Specialise a schema (WaterML2.0) – Write a profile document for a generic standard (NetCDF-CF, Hydro

profile of SOS, INSPIRE metadata profile)– These are all high burden for all stakeholders – and the machine-

readable parts are not very expressive– OGC Modular Specification – more expressive but document centric

• We cannot expect Citizen Scientists – or their communities of practice – to manage this – not scalable

Problem (mechanics)Problem (mechanics)

• Complex schema – whittle down to round peg, square peg.• Extensions


OGC®

We have a patternWe have a pattern

• “Modular specification”• == class/interface hierarchies• Software tools handle these seamlessly.• Can we make this easily accessible to stakeholders in the

interoperability chain?


OGC®

• What are the key things we need to express better?– Nature of things

• OWL, RDFS– Content – domain, range, granularity and subsetting

• SKOS,RDF-QB– Aggregation of data into sets, and binding of interfaces to these

• VoiD– Derivation (procedure parameters?)

• PROV

• Initial capabilities deployed…– Open source

• Refining and populating with real data for COBWEB Use Cases

• Development of client software to demonstrate potential• Full Proof-of-concept at Orlanda• Best Practices documents in preparation:

– Multiple stakeholder view of interoperability value chain– Profile methodology– COBWEB/Citizen Science BP for O&M
