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 { "@context": "http://schema.org", "@type": "ImageObject", "contentUrl": "http://images.slideplayer.com/14/4216373/slides/slide_3.jpg", "name": "Are these the same.", "description": "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

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 | http://lov.okfn.org/dataset/lov/

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

9 Standard ontology of chemicals Cox, Simons, Yu | Observable property ontology http://purl.obolibrary.org/obo/chebi.owl >36 000 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 56-55-3} / per unit wet weight of biota / {Limanda limanda (ITIS: 172881: WoRMS 127139) [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 07-022r1, 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 http://environment.data.gov.au/def/property/ http://environment.data.gov.au/def/object/ http://environment.data.gov.au/def/unit/ http://environment.data.gov.au/def/op http://sissvoc.ereefs.info/search Cox, Simons, Yu | Observable property ontology 16 |
