The Valid Web is a software prototype implementing temporal extensions of the World Wide Web. The temporal dimension of interest is the valid time, which represents the evolution of data with respect of the real-world (or virtual) environment they describe. The prototype consists of a Web site browsable with MS Internet Explorer 5 (Ie5), which allows the selective processing of HTML/XML documents containing historical information or temporal data. The base techniques employed in the prototype design and development, which derive from the temporal database theory, are the adoption of data timestamping andtemporal selection operators for the creation and management of Web pages, respectively.

Abstract
The Valid Web is a software prototype implementing temporal extensions of the World Wide Web. The temporal dimension of interest is the valid time, which represents the evolution of data with respect of the real-world (or virtual) environment they describe. The prototype consists of a Web site browsable with MS Internet Explorer 5 (Ie5), which allows the selective processing of HTML/XML documents containing historical information or temporal data. The base techniques employed in the prototype design and development, which derive from the temporal database theory, are the adoption of data timestamping andtemporal selection operators for the creation and management of Web pages, respectively.
