Hi Andy, thanks for the immediate reply. We actually use "en-gb" for UK English in our model – but anyway… My test-Scenario looks like ?lang = "de" ?locale = "de" which in langMatches(lang("wort"@de-de),(concat(str(?lang),"-",str(?locale))) ) unfortunately does not evaluate as true, althou

Fuseki 2: Security issue “Information Exposure”

Dear All, for a customer we'd like to use Fuseki 2.3.1. on Linux RedHat as a standalone server. Unfortunatelly we've encountered an anomaly of "Information Exposure" (CWE-200 - http://cwe.mitre.org/data/definitions/200.html), in particular the Fuseki and JETTY versions are showed. For example, if

Re: Concatenating language and locale in SPARQL 1.1

I wonder if the problem is to do with the datatype of the string resulting from concat()? Can you try doing a BIND(concat(str(?lang),"-",str(?locale)) AS ?langMatch) in your query and selecting that variable out to see what value you get, in particular I'm wondering if you are getting a typed lite

Re: Concatenating language and locale in SPARQL 1.1

Works for me: (jena 3.0.1) langMatches(lang("wort"@de-de),(concat(str("de"),"-",str("de"))) ) so it looks like ?lang or ?locale. Try adding ?lang and ?locale Just the results don't provide a complete minimal example though I note they do not have ?Headline If you have some short, sample da

Re: Concatenating language and locale in SPARQL 1.1

Hi Rob, thanks for the hint – seems you hit something here: The binding you described works properly as BIND(concat(str(?lang),"-",str(?locale)) AS ?langMatch) . indeed returns "de-de" for the ?langMatch variable. However simple string-making via langMatches((lang(?mailHeaderSubject))

Re: Concatenating language and locale in SPARQL 1.1

This just happened to catch my eye, and while I don't have a solution, it does look like there could be something going on with datatypes. If nothing else, here's some short code that might help in testing. Using just ?locale: prefix xsd: prefix rdf:

In Brando's code, everything is str()'ed. Only unbound will defeat that. (It is on a Mac though and "-" may not be "-" somewhere :-) Substituting from the srj file: arq.qexpr 'langMatches((lang("Unsere Lieblings-Testmail"@de-de)) , (str(concat(str("de"),"-",str("de") ' ==> true. (

Re: How to remove consistently a triple pattern given a SPARQL query?

The approach I would take is to do this is multiple passes: 1/ remove from ElementPathBlock 2/ Look for elements that are now "empty" e.g ElementFilter with empty but also as there one arm of a UNION. (2) is only one pass as the rewrite is done bottom up. I would do this as a transformation r

If you want to lock down a java-based webapp server, jetty, tomcat, fuseki whatever, then another starting point is to put it behind a reverse proxy (httpd, nginx etc), slave the java server to only receive request from localhost i.e. the reverse proxy. httpd, nginx have a much greater range o
