Title:

Quality issues with example snippets on https://dcat-ap.ch/releases/2.0/dcat-ap-ch.html

Content:

Some example snippets have invalid turtle syntax: 3, 17, 52 (and likely more ...)

The @prefix dcatap: <http://data.europa.eu/r5r/> . is missing from C. Verzeichnis der referenzierten Namensräume. It should be listed there

Example 64:
The datasets at the very bottom of the example have the wrong type, should be dcat:Dataset

Example 17:

• The main resource of the example - <https://swisstopo/api> - has a misleading IRI and wrong type, should be dcat:Dataset
• The publisher IRIs are not matching: <https://swisstopo/> versus <https://swisstopo>

Example 31:

• The title for the example should be "Usage of dct:accessRights for dcat:Dataset"
• The example is using dct:rights, this should be dct:accessRights instead

Example 41:

• dct:accessURL, this should be dcat:accessURL instead
• dct:availability, this should be dcatap:availability instead
• dct:format dcat:format <http://publications.europa.eu/resource/authority/file-type/CSV> ; is a statement with more than one predicate
