These, plus a variety of other issues, are crucial aspects to all long-term archiving, and define how audio archiving is performed. As time has progressed, fewer documents are created in paper-based forms, while are instead created in a digital form initially. Each record suits a purpose, in that every record must have some significance that will help benefit future generations. It is not useful to attempt storage of insignificant data which will have no benefit or relation to any aspect of the future or of our lives today. Although these simple factors should make deciding which records to save and how to maintain them for future generations an easy task, the current real situation is somewha...

For distributed systems with less-structured tasks, more-diversified information, and a heterogeneous user set, the computing system must administer enterprise-chosen access control policies. One kind of resource is a digital library that emulates massive collections of paper and other physical media for clerical, engineering, and cultural applications. This article considers the security requirements for such libraries and proposes an access control method that mimics organizational practice by combining a subject tree with ad hoc role granting that controls privileges for many operations independently, that treats (all but one) privileged roles (e.g., auditor, security officer) like every other individual authorization, and that binds access control information to objects indirectly for scaling, flexibility...

This paper presents a method of updating replicas that need not be immediately synchronized with the source data or with each other. The method allows an arbitrary mapping from source records to replica records. It is fail-safe, maximizes workstation autonomy, and is well suited to a network with slow, unreliable, and/or expensive communications links. The algorithm is a manipulation of queries, which are represented as short encodings. When a response is generated, we record which portion of the source database was used. Later, when the source data are updated, this information is used to identify obsolete replicas. For each workstation, the identity of obsolete replicas is saved until a workstation process asks for this information. This workstation process deletes each obsolete replica, and replaces it by an up-to-date version either prompt...

The use of this operating system component for data base security and integrity in a research and engineering environment is described. The techniques described make possible controlled access to the system's processing power, controlled access to the database, decentralized authorization responsibility, measuring dataset usage, and event recording for automatic dataset migration, archiving, and staging.
