KBART 4.2.3: incorrect date coverage

Core problem:


The presentation of inaccurate dates by content providers, or failure to
update dates in the knowledge base by knowledge base developers, causes inaccurate
results or failed links in the link resolver.

User impact:


Individuals may be told that a resource they seek is not available when it
is (for example, if the file is not updated to reflect the most recent issues online) or that a
resource is available when it is not (for example, if content has been removed but is still
listed in a holdings list). In the former case, valid usage will decrease; in the latter,
individuals will eventually shy away from using the resource if attempts to follow links to
it regularly result in dead ends.

Solutions:


Content providers should provide accurate holdings files of coverage dates
in a timely fashion; link resolver owners should ensure they are processing holdings files
correctly and promptly.
