Hi !

Just a question : why # caracter is invalid into @base ?

Thx !
Blaise

Dear all!

I potentially found some problem when parsing turtle for validation. The following turtle snippet works as an example:

@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xml: <http://www.w3.org/XML/1998/namespace> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

@prefix ctrl:   <http://w3id.org/ibp/CTRLont#> .

@prefix : <http://example.org/test#> .

# Note the newline below
:item a ctrl:ControlActor , owl:NamedIndividual ;

:item ctrl:hasInput :input .

The turtle validator states this syntax is correct; However, when loading it to GraphDB I receive an error.

I am not sure if this indeed is valid turtle and it would be great to discuss. If it is valid I will shift this issue towards the GraphDB developers.

Thanks in advance!

Hi, I used your tool for my project to validate my .ttl file, which will be part of a publication. How can I cite this work, this project? I see you have a clear license, but it might be useful to add a DOI to your GitHub page. Are you planning to publish on this project?

Hi!

Cool little application you've made here. Useful for when one is uncertain about why a Turtle file wont parse.

I have a request though: would it be possible to install it as a Javascript library? By that I mean the possibility of installing it in my own client side application, and for example importing a function called "validateTurtle"?

The "validateTurtle" function could for example return an object like: { validated: false, reason: "Something went wrong" }. That would make it easier for me as a developer to ensure that the uploaded (in our case we upload Turtle files to a store) is actually a valid Turtle.

Hello,

I use your http://ttl.summerofcode.be/ tool almost everyday. It saves so much time for files that are sometimes gigantic !

I recently lost my mind over a mapping that did not go through :

@prefix rr:     <http://www.w3.org/ns/r2rml#> .
@prefix era:	<http://data.europa.eu/949/> .
@prefix skos:	<http://www.w3.org/2004/02/skos/core#> .
@prefix prov:   <http://www.w3.org/ns/prov#> .

<https://data.infrabel.be/mapping/rinf/Link/opStart-opEnd/>
  skos:comment "Maps the link between Operational Point and SectionOfLine start with the ERA vocabulary";
  prov:used <https://data.infrabel.be/mapping/rinf/Link/SectionOfLine/OperationalPoint/>;
  a prov:Activity,
    rr:TriplesMap;

  rr::logicalTable [rr:sqlQuery """
  select op.uniqueopid, linesectionid
  from s1390.rinf_operationalpoint op
  join s1390.rinf_section_of_line sol on op.ptcar_id = sol.ptcar_from  
  """ ; ];

  rr:subjectMap [
    rr:template "https://data.infrabel.be/data/SectionOfLine/{linesectionid}" ; 
    rr:termtype rr:IRI  ];

  rr:predicateObjectMap [
    rr:predicate era:opStart;
    rr:objectMap [ rr:template "https://data.infrabel.be/data/OperationalPoint/{uniqueopid}";
                  rr:termtype rr:IRI ]].

If we copy and paste this into the tool, it does not catch that we have a typo rr::logicalTable (two columns instead of only one). Perhaps it's still valid turtle but I'm not really sure.

I was expecting the following behavior

ttl my_ttl_file_with_errors.ttl && echo "success" || echo "failed"
# => failed

instead this is what happens

ttl my_ttl_file_with_errors.ttl && echo "success" || echo "failed"
# => success

the reason being that the process exit code is always 0: could there by a process.exit(1) in case an error was detected, either by default or with an option passed to the executable?

thanks for this great tool!

Thanks for your tool! It's useful.

I found a small issue. It seems not be able to handle filenames/filepaths with spaces.

ttl "/Users/rick/Documents/Wikipedia/Deelcollectie Nederlandse Spoorwegen/2 juni/THWTW-CommonsCategories.ttl"
[Error: ENOENT: no such file or directory, open '/Users/rick/Documents/Wikipedia/Deelcollectie%20Nederlandse%20Spoorwegen/2%20juni/THWTW-CommonsCategories.ttl'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '/Users/rick/Documents/Wikipedia/Deelcollectie%20Nederlandse%20Spoorwegen/2%20juni/THWTW-CommonsCategories.ttl'
}

The syntax error of having spaces between literal and the language tag or the datatype definition is not detected. I assume that spaces are removed before the validation check as this error remains undetected.

N3 file containing '=' as shortcut for owl:sameAs.

[Syntax error: unexpected "=" on line 21.]
Validation done: 1 errors found.
