What conference PIDs could do for proceedings' integrity

As a publisher of open access conference proceedings series, TIB Open Publishing has a vital interest in persistent information about the conferences the proceedings volumes correspond to. Often, same URLs are reused by subsequent conferences or websites are not maintained after the end of an event. This can cause downstream problems for publishers: e.g., some indexing services inquire about scientific committees and other conference details. Hence, if such information is lost it might have negative impacts on the visibility of conference publications. The presentation explores how conference PIDs could help to avoid those problems.
