Getting Technical - Linking UKSG SRM 10 Linking Mechanisms The DOI is analogous to the Universal Product Code (UPC) bar code But… the DOI is not equivalent to a Universal Resource Locator (URL) A URL points to the location (to an instance) of content. Whereas a DOI permanently names that CONTENT and facilitates retrieving multiple instances of it, or of other associated information

This is where NISO fits in. …over five hundred years ago Guttenberg fundamentally changed communication and learning. Today NISO's challenge is to create those standards that will enable the modern day Gothenburg Moment. Could it be the OpenURL?"
