 ## Exercise
 
 1. Implement a new resource `/echo` that responds with the request body when posting (HTTP POST) to it; it should simply mirror the request back as response.
-2. Add content negotiation to the echo resource and convert the payload: if the request is made with MIME type `text/csv` (i.e., `Content-Type: text/csv`), and the response is expected to be delivered in `text/html` (i.e., `Accept: text/html`), then convert from CSV to a simple HTML table. Very basic handling of the CSV payload (use the snippet from the next section) is sufficient, you don't need to use third party libraries to handle advanced CSVs with apostrophes, line breaks, etc..

Only requests with `Content-Type: text/csv` and `Accept: text/html` need to trigger a conversion, all other requests should behave as described in 1. above.
 
 Bonus for the Linked Data experienced:
 
-3. Add support for the output format `text/turtle` (the [RDF Turtle serialization format](https://www.w3.org/TR/turtle/)) to the echo resource. Use appropriate properties from the [Dublin Core Terms metadata specification](https://www.dublincore.org/specifications/dublin-core/dcmi-terms/).
