All ecological measurements (plant height, animal count, soil pH, air temperature) in Ecoplots are represented as observations. (TERN’s LinkedData site has more information about Observations).
Observations
You can use this endpoint to extract observations based on several search criteria (see Search queries).
To retrieve observation data available in EcoPlots, you should use the /observations endpoint.
Request example:
curl -X POST "https://ecoplots-test.tern.org.au/api/v1.0/observations?dformat=ndjson" -H "accept: */*" -H "Authorization: apikey-v1 your-api-key" -H "Content-Type: application/json" -d "{\"query\":{\"dataset\":[\"http://linked.data.gov.au/dataset/ausplots\"],\"site_id\":[\"http://linked.data.gov.au/dataset/ausplots/site-nsabbs0001\"],\"feature_type\":[\"http://linked.data.gov.au/def/tern-cv/b311c0d3-4a1a-4932-a39c-f5cdc1afa611\"],\"observed_property\":[\"http://linked.data.gov.au/def/tern-cv/56195246-ec5d-4050-a1c6-af786fbec715\"]}}"

Observation attributes
Observations can have additional attributes. E.g., an observation might have an attribute “angle count point name”, but not all sampling protocols record this attribute, so the property does not belong to the Observation itself and it is defined as an additional attribute.
You can download all these attributes through the /observations/attributes endpoint.
Request example:
curl -X POST "http://localhost:5000/api/v1.0/observations/attributes?dformat=ndjson" -H "accept: */*" -H "Content-Type: application/json" -d "{\"page_number\":1,\"page_size\":10,\"query\":{\"dataset\":[\"http://linked.data.gov.au/dataset/ausplots\"],\"site_id\":[\"http://linked.data.gov.au/dataset/ausplots/site-nsabbs0001\"]}}"
