The designing of Web services to deliver Web documents associated with historical links

The historical links of a Web site include the URLs invalidated due to Web site reorganization, document removal, renaming or relocation, or links to document snapshots, which are defined as the document's contents as of a specific point in time. Tracking historical links allow users to use out of date URLs, retrieve removed documents and document snapshots. This paper presents a logging and archiving scheme to track a document's history of changes, and designs a Web service to deliver the Web document associated with a historical link.
