We do lots of record exchange in Germany between various systems. In the exchange format, it’s common to have both the heading in textual form and the national authority control number, but I’m fairly sure it would be no problem if only the control number were transported, without a text string. Whenever e.g. data from the German National Library is imported into the Southwestern German Library Network, I believe there is a procedure which automatically exchanges the national authority control number with the correspondent record numbers in our union catalog (where we have a complete and regularly updated duplicate of the national authority file) and re-builds the links. I hope I’m making sense here – there are certainly people who could explain this much better than me. But be assured it can be done (without having to wait for Linked Data) if there are unique identifiers (in our case, the national authority control number). So, it should also be possible to use the same techniques for linked WEMI records, if we had them.

As I have mentioned before, a URI does not have to be a number, but can be any string of characters, so long as it is unique. Also, any entity can have more than a single URI. Therefore, according to cataloging practice of no conflicts in headings, the VIAF fulfills this role right now since it can supply exact matches of preferred forms for specific national libraries. So, a search for exact preferred forms for, e.g. Fyodor Dostoyevsky, works now. All of these searches are for exact forms restricted to national forms.
LC form:,%20Fyodor,%201821%201881%22+and+local.sources+any+%22lc%22&stylesheet=/viaf/xsl/results.xsl&sortKeys=holdingscount&maximumRecords=100
Czech form:,%20Fedor%20Michajlovi%C4%8D,%201821%201881%22+and+local.sources+any+%22nkc%22&stylesheet=/viaf/xsl/results.xsl&sortKeys=holdingscount&maximumRecords=100
Israeli form:,%20%D7%A4%D7%99%D7%95%D7%93%D7%95%D7%A8%20%D7%9E%D7%99%D7%9B%D7%90%D7%99%D7%9C%D7%95%D7%91%D7%99%D7%A5′,%201821%201881%22+and+local.sources+any+%22nliara%20nlilat%20nlicyr%20nliheb%22&stylesheet=/viaf/xsl/results.xsl&sortKeys=holdingscount&maximumRecords=100

and so on. This way, it could work similarly to dbpedia which does not base its URIs on numbers but on consistent textual strings, e.g., and brings together other URIs through owl:SameAs.

Currently in VIAF, I have noticed some inconsistencies in search results, e.g. the exact heading for Martin Luther,,%20Martin,%201483%201546%22+and+local.sources+any+%22lc%22&stylesheet=/viaf/xsl/results.xsl&sortKeys=holdingscount&maximumRecords=100, which incorrectly pulls up three of his works in addition to his personal record, although this is supposed to be an exact search. When you switch to search for “Preferred Headings”, you get 307,%20Martin,%201483%201546%22+and+local.sources+any+%22lc%22&stylesheet=/viaf/xsl/results.xsl&sortKeys=holdingscount&maximumRecords=100
