Reply-To: VIVO Development List <>

Hi. The DOI system is built upon the Handle identifier resolution infrastructure ( There's several "flavours" of DOIs for digital content, created different communities and purposes. The most significant ones are the DOIs issued to the majority of STM publications via CrossRef ( and to increasing numbers of scientific datasets in digital repositories via DataCite (

DOIs (and also non-DOI Handles) can be treated as URIs by representing them prefixed by URLs which point to central resolver services, usually For example, is a unique, resolvable URI identifier for the PLoS article currently located at

Both CrossRef and DataCite recently launched add-ons to their resolution services to support the use of DOI URIs in Linked Data applications such as VIVO:

Content Negotiation for CrossRef DOIs -
DataCite supporting content negotiation -

See geeky curl-exercise below to get an idea of the kind of stuff you get back from dereferencing one of those URIs.
