Scenarios Bill Arms reviewed several reference linking scenarios . Bill Arms noted that the early DOI model assumed that a user with a DOI in hand would be routed from the DOI system directly to the publisher of the article. In the current model multiple alternative locations may exist, and the user, a library, or the publisher itself may want to mediate which is selected. All three of these players have different goals, as do the authors. Libraries want to satisfy readers, resolve identifiers to the definitive version, minimize costs, and collect good statistics.
Readers have the most varied goals of all.
They want to resolve identifiers to the most appropriate version, but this may differ depending on circumstances. They also want fast, direct access to content, and links to related works by topic. One has to assume that there will be multiple reference databases, location databases and content databases. As a next step, the community should consider what levels of agreement and tools are needed for cross linking these. These may include a registry of reference linking schemes, hand-off protocols, and citation analysis tools.
