Extending Header to support Sesame OpenRDF

I found http-param and http-header clauses. That I added. I seen in the server log that a set of RDF data was downloaded. But I still get failures. I'm using the scraper. toString.documentation = "TODO: Add operation level documentation here" ; toString.inputTypes = { /* TODO: Add input types of this operation */ }; toString.outputType = "String"; /* TODO: Add output type here */ function toString() {var config = application/sparql-results+xml, */*;q=0.5 ; var scraper = new Scraper(config); var result = scraper.response; return result; } I'm getting a failure that I don't understand.

I didn't open and and close the xml notation for HTTP block correctly; therefore, the accept parameter wasn't being set properly. It's working. this.serviceName = "sesame"; this.documentation = "TODO: Add service level documentation here" ; toString.documentation = "TODO: Add operation level documentation here" ; toString.inputTypes = { /* TODO: Add input types of this operation */ }; toString.outputType = "String"; /* TODO: Add output type here */ function toString() { var config = application/sparql-results+xml ; var scraper = new Scraper(config); var result = scraper.response; return result;}

;-).

Thanks for posting the workaround you found :)
