Storage
Each Kvasir pod exposes an Amazon S3 compatible storage API at the base path /{podId}/s3. This API can be used to store and retrieve files in the pod's storage. Kvasir can be configured to automatically ingest files uploaded to the S3 API into the Knowledge Graph. At the time of writing, this feature is restricted to files of limited size in JSON-LD or Turtle format.
