Goals

• Information modelling work

  • Review the issues and PRs in GitHub for the TERN Ontology

    • https://github.com/ternaustralia/ontology_tern/pull/25#issuecomment-937276321

      • Simon says: “(might need to think about a co-constraint between sosa:observedProperty and sub-classes of tern:Value)”

        • for example tern:Taxonis a class whose membership (extension) is the list of taxa, but might also be thought of as an individual of type tern:ObservableProperty

        • Refer to how the Yellow Book was encoded in RDF

  • Modelling deployment information of TERN phenology cameras (phenocams) within the TERN Ontology

    • Phenocams are Samplers in our case, not Sensors.

    • Samplers produce samples

    • Sensors produce observations

    • What do we consider an image produced by the phenocam?

    • We think it fits well with the shape of Sampler, Sample and further Observations on Features of Interest.

• Documentation for technical users and implementors

  • Show the TERN Ontology SHACL constraints viewer and get feedback

    • Temporary URL: https://19f1-2406-3400-45d-7e00-e01d-81c2-c3b-4409.ngrok.io

    • A viewer will also allow us to redirect the class and property URIs to something on the web

    • Generated from the SHACL ontology - no need to manually keep in sync

  • Ask Simon for input and help on what technical documentation is required/useful for technical implementors of the exchange standard

Deployment information of TERN phenocams

Open

Deployment diagram.

A phenocam is a Sampler. Samplers are types of Systems which have deployment information expressed as Attributes. A system can be deployed on a Platform, such as Flux stations.

EcoImages phenocams faceted search: TERN EcoImages: Search

Open

EcoImages image type and camera type facet navigation.

Each facet is an Attribute of the Deployment

• Phenocam FOV (deployment)

  • ID of the deployment

• Angle (controlled vocabulary)

  • Example value: oblique

• Position (controlled vocabulary)

  • Example value: overstorey

• NVIS Major Vegetation Group (controlled vocabulary)

  • Example value: Acacia Forests and Woodlands

• Camera Type (controlled vocabulary)

  • Example value: Timelapse Camera

Discussion topics

Action items

Decisions

1. Remove tern:Instrument
2. Phenocams are tern:Samplers and not tern:Sensors
