json serialisation misses @base #80
Description
The json serialisation, for example at https://data.bibliotheken.nl/doc/thes/p068842368.json , misses the @base in the @context. That results in incorrect URIs. In the provided example, the main URI is "id/thes/p068842368" in stead of "http://data.bibliotheken.nl/id/thes/p068842368".
With @base added, as shown here,
"@context" : {
"@base" : "http://data.bibliotheken.nl/",
this would be fixed.
