Key URLs for a publication, such as a publication’s home page, should not change over time. If they must change, redirect the original URL to the new location. Apart from helping to decrease broken links from other websites, using a well planned URL structure can help with website preservation. Ensuring the publication’s URL does not change over time can make it easier to manage and connect different versions of the publication that are preserved and avoid duplication.
These guidelines discuss identifiers, another way to support URL persistence:
27. Persistent identifiers can be used at the publication resource level
31. Persistent identifiers should assigned to new versions of the work
