Proposed APIs

The GET Endpoints URI contains information about the anchors . But, and the format of the anchor data is different in both CPS Core and CPS-temporal, which can cause some confusion. Hence, two endpoint format have been proposed.The filtering rest of the filtering criteria are passed as query parameter. The below-mentioned query parameters are supported by all endpoints.

...

The response format for endpoints is the same and defined here

By Dataspace and Anchor

...

URL: GET /dataspaces/{dataspace-name}​/anchors/{anchor-name}​/history

Example: GET /dataspaces/{dataspace-name}​/anchors/{anchor-name}​?after=2021-03-21T00:00:00-0:00&simplePayloadFilter={"idNearRTRIC":"1"}&limit=500

Endpoint Format B

URL: GET /dataspaces/{dataspace-name}​/anchor-data?anchor={anchor-name}

Example: GET /dataspaces/{dataspace-name}​/anchor-data?anchor={anchor-name}​&/history?after=2021-03-21T00:00:00-0:00&simplePayloadFilter={"idNearRTRIC":"1"}&limit=500

By Dataspace and Schema-set

...

URL: ​GET /dataspaces/{dataspace-name}/anchors/history?schemaSet={schemaset-name}

Example: GET /dataspaces/{dataspace-name}/anchors?schemaSet={schemaset-name}&after=2021-03-21T00:00:00-0:00&simplePayloadFilter={"idNearRTRIC":"1"}

Endpoint Format B

URL: ​GET /dataspaces/{dataspace-name}/anchor-data?schemaSet={schemaset-name}

Example: GET /dataspaces/{dataspace-name}/anchor-data?schemaSet={schemaset-name}&after=2021-03-21T00:00:00-0:00&simplePayloadFilter={"idNearRTRIC":"1"}
