California Digital Library

This paper will describe the tools and infrastructure components which have been implemented by the CASPAR project to support repositories in their task of long term preservation of digital resources. We address also the capture and preservation of digital rights management and evidence of authenticity associated with digital objects. Moreover examples of ways to evaluate a variety of preservation strategies will be discussed as will examples of integrating the use of these infrastructure components and tools into existing repository systems. Examples will be given of a rich selection of digital objects which encode information from a variety of disciplines including science, cultural heritage and also contemporary performing arts.
