Multiple resolution with 10320/LOC element (see Multiple DOI Resolution (Multiple URLs)) is useful for building applications where the required evaluation is to choose from a set of possible outcomes based on some criteria. An application developer could create a type in which to store values used by a client to generate a menu of options for a user when the user resolves a DOI name. In the case of a document, the user might be given the option to view the document, view document metadata, share the document by emailing the URL to an associate, visit the author's blog, etc. For a dataset, the choices offered to the user on the landing page may include viewing the complete dataset, viewing only selected data, or some other choice of interaction with the dataset based on the information made available to a client via resolution of the DOI name.
For example, scholarly journal articles are assigned one DOI name, but they can be available from multiple web sites, and readers may wish to download an article from a service to which they are subscribed. Crossref uses multiple resolution to enable users to resolve an article's DOI name, and choose which version of an article they wish to view, as illustrated below.
