Hi. The DOI system is built upon the Handle identifier resolution infrastructure (http://www.handle.net). 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 (http://www.crossref.org) and to increasing numbers of scientific datasets in digital repositories via DataCite (http://data.datacite.org).
DOIs (and also non-DOI Handles) can be treated as URIs by representing them prefixed by URLs which point to central resolver services, usually http://dx.doi.org. For example, http://dx.doi.org/10.1371/journal.pcbi.1000388 is a unique, resolvable URI identifier for the PLoS article currently located at http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1000388
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 - http://www.crossref.org/CrossTech/2011/04/content_negotiation_for_crossr.html
DataCite supporting content negotiation - http://www.crossref.org/CrossTech/2011/10/datacite_supporting_content_ne.html
See geeky curl-exercise below to get an idea of the kind of stuff you get back from dereferencing one of those URIs.
