Technical background information

NOTE: The original JEL download files do not come with version identifiers. The Linked Data downloads on http://zbw.eu/beta/external_identifiers/jel/ carry version dates and identifiers, which reflect to (rather arbitrary) time of the download. Because the files were extracted from language-specific RDFa pages, some of the version strings carry language tags and must be referenced as, e.g., "2012-09"@en.
