1 Observable properties ontology – alignment and usability Simon Cox, Bruce Simons, Jonathan Yu | Environmental Information Systems 12 June 2014 LAND AND WATER

2 AGU Fall 2013 | IN52B-08 | Cox, Simons, Yu | Vocabulary re-use Healthy Headwater - NGIS Terms collection alt names hierarchy

3 Are these the same? Cox, Simons, Yu | Observable property ontology “nitrogen” “dissolved nitrogen” “Total nitrogen, water, filtered, milligrams per liter” “Concentration of nitrogen (total) per unit volume of the water body [dissolved plus reactive particulate phase] by oxidation and colorimetric autoanalysis“ “Concentration of nitrogen (total) per unit mass of the water body [dissolved plus reactive particulate

4 ‘Parameters’ in an environmental science vocabulary (NVS) Cox, Simons, Yu | Observable property ontology 4 |

6 Requirements Simple properties Constrained properties Compound properties Property series Composite properties Cox, Simons, Yu | Observable property ontology 6 | Cox, OGC Implementation Specification – Observations and Measurements 1.0 – Part 1 – Observation Schema

7 We are not alone! OKFN Linked Open Vocabularies Cox, Simons, Yu | Observable property ontology 7 |

8 Conceptual Model of QUDT Cox, Simons, Yu | Observable property ontology 8

9 Standard ontology of chemicals Cox, Simons, Yu | Observable property ontology > chemical entities 9 |

10 AGU Fall 2013 | IN52B-08 | Cox, Simons, Yu | Vocabulary re-use Dissolved nitrogen concentration objects ScaledQuantityKind SubstanceOrTaxon Unit

11 AGU Fall 2013 | IN52B-08 | Cox, Simons, Yu | Vocabulary re-use Water Quality extension to QUDT  QUDT  WQOP

12 Mix-n-match parameter definitions Concentration of / benz(a)anthracene {CAS } / per unit wet weight of biota / {Limanda limanda (ITIS: : WoRMS ) [Sex: male / Subcomponent: liver]} Cox, Simons, Yu | Observable property ontology 12 | Substance | matrix-relationship | context of matrix (taxon) | matrix | method

13 AGU Fall 2013 | IN52B-08 | Cox, Simons, Yu | Vocabulary re-use Linked to SKOS

14 Cox, Simons, Yu | Observable property ontology 14 |

15 AGU Fall 2013 | IN52B-08 | Cox, Simons, Yu | Vocabulary re-use How does this relate to O&M? [Scaled]QuantityKind qudt:generalization op:constraint Cox, S. J. D. (ed.) (2007). Observations and Measurements – Part 1 - Observation schema. OGC r1, Open Geospatial Consortium Inc. “Concentration” “nitrogen” op:featureOfInterest op:procedure PropertyKind op:matrix op:objectOfInterest

16 Summary Observable property vocabularies should be Standardized Published Extend / re-use existing vocabularies where possible Publish it somewhere good Cox, Simons, Yu | Observable property ontology 16 |

17 LAND AND WATER Thank you CSIRO Land and Water Simon Cox Research Scientist t wwww.csiro.au/people/simon.cox

18 AGU Fall 2013 | IN52B-08 | Cox, Simons, Yu | Vocabulary re-use object.ttl chebi.owl wq.ttl imports into chebi_skos.ttl object-chebi -mapping.ttl imports into imports into manually create skos:exactMatch statements transform subset of owl:Class to skos:Concept add prov:hadPrimarySource Subset of SubstanceOrTaxon Mapping chemical substances to ChEBI manually create skos:exactMatch statements Alternative approach to map skos concepts to ChEBI classes
