τXSchema toolset comes with three snapshot documents (catalog1.xml, catalog2.xml and catalog3.xml). These snapshots are initially generated using XBench and are modified to show all kinds of variations in temporal XML document. The snapshots record a publisher's catalog on 1/1/2002, 2/1/2002 and 3/1/2002 respectively. The information that can change between two succesive snapshots is specified in the logical annotation document (catalog.tsd). It includes the address and telephone number of authors, the relationship between books, the quantity in stock, etc. The positions where the timestamps can be added in the temporal XML document are specified by the physical annotation document (catalog.psd). The third document (catalog.xsd) is the schema file for the snapshots. These documents are for user to test the functionality of τXSchema toolset. They are also the documents used in samples.
