Multiple resolution with 10320/LOC element (see Multiple DOI Resolution (Multiple URLs)) can be used to enable a DOI resolver to choose what the outcome of resolving a DOI name will be for a specific user, based on a given criteria. The figure below shows (non-administrative) elements associated with DOI name 10.1525/bio.2009.59.5.9. When this DOI name was registered it had a single URL element (type of URL and value, aka data, equal to a JSTOR URL). A 10320/LOC type was added to provide instructions for offering other resolution options (see 10320/LOC: XML Attributes for information about the XML attributes used in 10320/LOC element). When this record is returned to the DOI Proxy, it recognizes the 10320/LOC type and, if asked to do so, performs an evaluation of the location values based on a given criteria.

 

The DOI Proxy may be required to (see also DOI Proxy Query Command Format):

•ignore type 10320/LOC
In that case, the DOI Proxy would resolve 10.1525/bio.2009.59.5.9 and select the URL value https://www.jstor.org/stable/25502450. This action would be performed by any DOI resolver not knowing the type 10320/LOC.

•resolve 10.1525/bio.2009.59.5.9 and return to the user both of the URLs in the cr_type attributes in the 10320/LOC value, letting the user choose the next action (choose-by mechanism)

•resolve 10.1525/bio.2009.59.5.9?locatt=country:gb
In that case, the DOI Proxy would determine the user's geographic location from their IP address. It would then select the URL https://www.bioone.org/doi/full/10.1525/bio.2009.59.5.9 for users in the UK ("gb" code), and would perform a random selection for all others.

•resolve 10.1525/bio.2009.59.5.9?locatt=id:1
In that case, the Crossref metadata service at https://mr.crossref.org/iPage?doi=10.1525%2Fbio.2009.59.5.9 would be selected.
