Description

I've fixed several recoverable json-ld parsing errors, but there are also errors of the (probably) non-recoverable kind, e.g.,

com.fasterxml.jackson.core.JsonParseException: Unexpected end-of-input: was expecting closing quote for a string value

caused by the following JSON:

{
	  "@context": "http://schema.org",
	  "@type": "Organization",
	  "url": "http://osl.ugr.es",
	  "contactPoint": [{
	    "@type": "ContactPoint",
	    "email": "[e-mail]",
		"name": "Jornadas de Software Libre"
	    "contactType": "Organizing committee",
		"url": "http://osl.ugr.es":
	  }]
	}

Errors of the recoverable kind should be fixed, whereas errors of the non-recoverable kind should be reported as fatal errors without causing the rest of the extraction process to fail.
