Umlaut is an open source project originally developed by Ross Singer while at Georgia Tech, and subsequently worked on quite a bit by Jonathan Rochkind of Johns Hopkins University. Umlaut is sometimes called a “link-resolver front end” or a “middle-tier link resolver”. In fact, the Umlaut is a link resolver, in the sense that it receives OpenURL requests–usually representing a citation for a scholarly work–and responds with information on services available related to that citation–most significantly, with electronic availability. However, unlike most typical link resolver products (such as SFX), the Umlaut does not manage it’s own “knowledge base” of information on what titles an institution possesses from what vendors, and how to link to them. Umlaut relies on SFX–accessed through the SFX API–for that information and service.
