Can Fuseki load Turtle datasets?

[Luí­s Moreira de Sousa <lu...@protonmail.ch.INVALID>]

Hi there,

I am trying to load a few datasets created with Protege and saved in the Turtle format. Whenever I try to load one of these datasets to Fuseki I get the following error message:

Result: failed with message "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data"

Is Turtle really supported by Fuseki? How could I otherwise load a dataset created with Protege?

Thank you.

Fuseki handles Turtle.

The request indicates (usually one of file extension, content-type) 
contains JSON(-LD).

What does the log file say the request is?

(if you run with "-v" you get more details of every HTTP request)

Which service of a dataset are you using to upload the data?

The log will have the request URL. If verbose, it has the HTTP headers 
as well.

Jena does not sniff data - it uses the information in the request and 
HTTP headers only.

 From the request URL, it takes the "file extension".

If it is a HTML form upload, the contained file may have a file name and 
that file extension is used.

I have now tested the same Turtle datasets against version 3.12 and 3.13, with those there is no error message and the datasets seem to get imported.

Dear all,

nothing ever came up in the logs that provided a clue to the cause of this error. However, the error was issued by a containerised instance with Fuseki 3.10. I have now tested the same Turtle datasets against version 3.12 and 3.13, with those there is no error message and the datasets seem to get imported.

I will drop more information if I understand this better.

Thank you.
