Turtle parser fails on valid turtle

[DieterDePaepe]

When loading the (valid) turtle file of the ISA Person Core vocabulary, I receive a parsing error:

Could not import given model: Character ";" not allowed in language tags.

which I assume originates from statements as

:Person dcterms:identifier "person:Person";
a rdfs:Class;
rdfs:label "Person"@en;

After adding a space before the ";", a less meaningful errors occurred:

Could not import given model: ':' expected. ' ' found instead (core_person/home>]; dcterms:descriptio). when parsing file:///tmp/

After adding some more spaces, the knowledge base is created, but gives an error page once it is viewed:

With the following in the logs:

I suspect the final error is also related to some kind of parsing error.

Tested using Docker without customisation of any kind: docker run -it -p 80:80 --rm aksw/ontowiki-ubuntu-nginx
