Bad RDF IRI syntax in several quads in LOV+Vocabs nq dump

[nvbach91]

Hi, I could not import several quads to Blazegraph. The problem is that these IRIs have a bad syntax. Is this an implementation detail or I missed something?

Examples of bad IRIs are

• Empty: <>,
• Web address without protocol: <www.beniculturali.it/>
• Email address without 'mailto:': <iker.esnaola@tekniker.es>

All of them throw the following error:

java.util.concurrent.ExecutionException: org.openrdf.rio.RDFParseException: _value_here_

The quads are the following. Dump date: 2019-07-18

After I removed them from the dump file, all the errors are gone.
