DAP4 Extension: CSV Data Encoding and Response

<< Back to OPULS Development

This DAP4 Extension describes the DAP4 CSV data encoding, how DAP4 servers advertise their support for the DAP4 CSV encoding, and how DAP4 clients can request DAP4 CSV encoded data responses. Though based on the text/csv media type described in RFC 4180^{[ RFC 4180]}, the DAP4 CSV is more complex so that it can represent the more complex data structures of the DAP4 data model.
