more internal links, categories; hard to find all this stuff
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.
==User Interface Flexibility==
==Check for Public Access Versions==
To discover if an open access version of an item is available, Umlaut does an author/title keyword search of IndexData’s indexes of OAISter and Open Content Alliance freely available text.. This is imperfect because all we can do is an author title keyword search. But when it works, it’s cool.
* Google Books search to complement the OCA and Gutenberg searches I’ve got.
* Connection to OCLC Identities
* xISBN/thingISBN use. (Some thought is required in how to integrate this while avoiding false positives). Bowker ISSN service for metadata enhancement. OCLC xISSN? Integrate preceding/succeeding title information from OPAC or xISSN?
* Integrate my various local document delivery services into menu of options when full text isn’t available.
