Surveyor not responding and JS errors: NaN

[jmvanel]

I think there is enough information to FIX in the console output;
otherwise I'll provide info on the (localhost) repo.
This was on Firefox 56.0 (64 bits) (on Ubuntu).

I'm checking the logs and trying to reproduce myself the errors.

From your output, I can see that everything is going well, except that "bootstrap.min.css.map" file is not found. I'm not sure why this file is requested (not needed in my tests), but I can upload it to the server.

When querying your endpoint, http://semantic-forms.cc:9112/sparql2, I've observed a problem with one of your classes that has an empty URI. Due to this, the function that extracts the namespaces breaks. I can fix this problem in the code, but you should also check your data. Please test the answers to the culprit SPARQL query and you'll find an empty URI value:

http://semantic-forms.cc:9112/sparql2?query=PREFIX%20rdfs%3A%20%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0ASELECT%20DISTINCT%20%3Fclass%20%0A%20WHERE%20%7B%20%0A%20%5B%5D%20a%20%3Fclass%20.%20%0A%20filter%20not%20exists%20%7B%20%0A%20%20%20%3Fclass%20rdfs%3AsubClassOf%20%3Fsuper%20.%20%0A%20%20%20filter%20(%20%3Fsuper%20!%3D%20%3Fclass%20)%20%0A%20%7D%20%0A%20filter%20not%20exists%20%7B%20%0A%20%20%20%3Fsub%20rdfs%3AsubClassOf%20%3Fclass%20.%20%0A%20%20%20filter%20(%20%3Fsub%20!%3D%20%3Fclass%20)%20%0A%20%7D%20%0A%20%7D&format=json&Accept=application%2Fsparql-results%2Bjson

[jmvanel]

OK, thanks for the diagnostic;
I'm aware that empty URI exist, due to a (fixed) bug.

I'll remove them with simple SPARQL update,
and let you know when ti's done.

Regarding
bootstrap.min.css.map
this is a classical issue: the .map files are not needed in normal processing;
but the console or JS debugger will try to read them, to provide source with the original line formatting in relation with the line numbers.
See this about .map files https://en.wikipedia.org/wiki/MAP_(file_format)

[jmvanel]

I removed the URI's <> in subject and object positions in my repo.

Now it goes further: 78 queries ! 👍

Hey, it's again the same problem with an empty URI. I'll include a check to discard those URIs and request a server update in our test website (http://tools.sirius-labs.no/rdfsurveyor/).

[jmvanel]

That will be nice;
however, I checked in my database the 3 possibilities for a triple to have the <> URI :

SELECT * WHERE { GRAPH ?G { <> ?P ?O . } }
SELECT * WHERE { GRAPH ?G { ?S ?P <> . } }
SELECT * WHERE { GRAPH ?G { ?S <> ?O . } }

nothing is returned.
I have the feeling that the surveyor problem is not "an empty URI" this time.

I checked my database on the original SPARQL service, that exposes the named graphs, e.g;
http://semantic-forms.cc:9112/select-ui?query=SELECT+*+WHERE+%7B+GRAPH+%3FG+%7B+%3C%3E+%3FP+%3FO+.+%7D+%7D
or:

http://semantic-forms.cc:9112/sparql?query=SELECT * WHERE { GRAPH ?G { <> ?P ?O . }}

And also with the new derived SPARQL service (the one you use), that does not expose the named graphs:

http://semantic-forms.cc:9112/sparql2?query=SELECT * WHERE { <> ?P ?O . }
http://semantic-forms.cc:9112/sparql2?query=SELECT * WHERE { ?S ?P <>  . }
http://semantic-forms.cc:9112/sparql2?query=SELECT * WHERE { ?S <> ?O . }

[guiveg]

The problem is that a couple of classes don't have proper URIs, e.g. doapFiles, so the function that extracts the namespaces returns undefined, firing an error when calling startsWith (see your log above).

I've made a quick fix and I'll update the code at github. I hope this fix will be made available soon in the test website.

Thanks for your support!

[jmvanel]

OK, I get it , <doapFiles> is indeed present, and is not an absolute URI, which should not be in a database !
I'll also make a SPARQL Update for these.

Note that later I plan to implement a sanity check in SF:
