These links IIRC are the same ones VIAF employs to link to a representation of the NAF records and they are broken for about 6 weeks now. To my knowledge the {{Authority Control}} Metadata in the English Wikipedia are inspired from a similar effort in the German Wikipedia, which since 2005 notes authority nunbers for persons: They started with PND numbers (Personennormdatei, the Collaborative Authority File for german and austrian libraries) and were backed by an agreement with the German National Library (Deutsche Nationalbibliothek, DNB) to provide mutual links from authority Records to Wikipedia and vice versa. Currently about 150.000 articles on wikipedia.de carry the associated PND number, many of them also LoC-NA and VIAF numbers: http://de.wikipedia.org/wiki/Vorlage:NORMDATENCOUNT The links from portal.d-nb.de to wikipedia.de are not implemented by 856-like manifest URLs in the authority records nor some kind of "wikipedia numbers" as additional identification numbers. Rather wikipedia.de publishes on a daily base a trivial concordance table relating extracted PND numbers to the corresponding wikipedia lemma. The DNB portal in turn incorporates this table and generates the respective links on the fly whenever an affected authority record is displayed. Some biographical dictionaries, regional bibliographies, classical OPACs and historical projects picked up this mechanism and published their own tables of this kind, all using the PND identification number as common system of reference. This (as such a low-tech approach to the semantic web) was coined "PND-BEACON": < http://de.wikipedia.org/wiki/Wikipedia:PND/BEACON > (english version: < http://meta.wikimedia.org/wiki/BEACON >) CKAN data package: < http://ckan.net/package/pndbeacon > Publishing such beacon files presupposes that your data already carries more-than-local identification numbers. With this precondition met, the gain is twofold: - - publishing a beacon file may direct vistors from the incorporators of the file to your catalogue - - the existing authority numbers in your cataloge enable you to relate (via their beacon files) to other web ressources, thus rounding up the data you present.
