Import of language tags with more than 2 letters (e.g. @en-US) not possible #111

Closed KonradHoeffner closed 8 years ago

KonradHoeffner commented 12 years ago

When I create a knew knowledge base via "Paste Source", I get the following error message:

Error importing knowledge base: Graph <http://test.com> could not be imported: Character "U" not allowed in language tags.

AFAIK this relates to the line og:site_name "Best Buy"@en-US ; which uses an extended language tag.

The full source code of the problem-causing RDF extracted from a best buy TV offer:

Whats the status of this issue?

KonradHoeffner commented 11 years ago

I just got a similar error (";" in language tag) when importing http://publishing-statistical-data.googlecode.com/svn/trunk/specs/src/main/vocab/cube.ttl.

The problematic part seems to be:

dcterms:contributor [foaf:mbox "richard@cyganiak.de"],
                    [foaf:mbox "jeni@jenitennison.com"],
                    [foaf:mbox "arofan.gregory@earthlink.net"],
                    [foaf:mbox "ian@epimorphics.com"],
                    [foaf:mbox "dave@epimorphics.com"];

This was a parser issue in Erfurt. It is fixed with commit 40c1caa in Erfurt.
