摘要： A web-based system, method and program product are provided for adding content to a content object stored (e.g., a custom compilation or prepublished work) in a data repository as a group of hierarchically related content entities. Each noncontainer content object is preferably stored as a separate entity in the data repository. Each content entity is also stored as a row in a digital library index class as a collection of attributes and references to related content entities and containers. As the user selects desired objects for inclusion in a content object, the system arranges the objects hierarchically, e.g., into volumes, chapters and sections according to the order specified by the user. The system then creates a file object (e.g., a CBO) defining the content object that contains a list or outline of the container and noncontainer entities selected, their identifiers, order and structure. This file object is stored separately in the data repository. An aspect of the invention is the calculation of the compilation's cost by estimating the amount of content it contains and determining a content cost based upon the content estimate. Optionally, a cost is assigned to each content entity in the data repository and these actual costs are summed as part of the cost estimation procedure.

摘要： A web-based system, method and program product are provided for adding content to a content object stored (e.g., a custom compilation or prepublished work) in a data repository as a group of hierarchically related content entities. Each noncontainer content object is preferably stored as a separate entity in the data repository. Each content entity is also stored as a row in a digital library index class as a collection of attributes and references to related content entities and containers. As the user selects desired objects for inclusion in a content object, the system arranges the objects hierarchically, e.g., into volumes, chapters and sections according to the order specified by the user. The system then creates a file object (e.g., a CBO) defining the content object that contains a list or outline of the container and noncontainer entities selected, their identifiers, order and structure. This file object is stored separately in the data repository. An aspect of the invention is to provide permission checking. Occasionally, it may be desired to prevent certain content entities from appearing a same compilation as other content entities. For example, an author may specify that his work can not be published in the same compilation as the work of another author. Permission checking first requires associating each container and noncontainer with any mutually exclusive containers or noncontainers. For example, such association may be achieved by defining a set of rules specifying containers and/or content entities that are mutually exclusive. Upon selection of a container or noncontainer to add to the compilation, the permission checking procedure determines if the container or noncontainer is mutually exclusive of any other containers or content objects, e.g., by consulting the rules. If so, the permission checking procedure then analyzes the compilation outline to determine whether any of the other mutually exclusive containers or noncontainers already exists in the compilation. If so, then the selected container or noncontainer is not added to the compilation and the user is notified that the content selected may not be included in the compilation. Otherwise, the content is added.

摘要： A client/server-based secure timekeeping computer system is provided. A secure-time server which is located in a physically trusted environment, includes a highly accurate time-of-day (TOD) clock, along with a key storage area containing a table of public/private key pairs corresponding to clients in the client/server network. The server encrypts a current time value from its TOD clock using a private key corresponding to a selected client. The encrypted time value is then sent to the client over an open communications channel. Each client in the network is equipped with its own secure timekeeping facility housed within the secure boundaries of a single, tamper-proof VLSI chip. Upon receipt of a secure-time transmission, a client uses its own copy of its private key to decrypt the time value, then loads the decrypted time value into its TOD clock. The tamper-proof VLSI chip in each client also includes an authenticated-time indicator, which is set to TRUE to indicate that the TOD clock contains a trusted time. Programs that require secure time may check the authenticated time indicator before executing and may cancel execution if a secure time is not available. Programs that do not require secure time are able to execute regardless. To maintain the ongoing accuracy of the client TOD clock once it is set with a trusted time value, the secure timekeeping facility in a client may further include calibration and clock stability adjustment mechanisms which receive client clock calibration adjustment values and accuracy duration values, and which apply these values at intervals to maintain the accuracy of the client TOD clock within acceptable limits and mark the clock as untrusted when it can no longer be maintained within acceptable limits.

摘要： A web-based system, method and program product are provided for adding content to a content object stored (e.g., a custom compilation or prepublished work) in a data repository as a group of hierarchically related content entities. Each noncontainer content object is preferably stored as a separate entity in the data repository. Each content entity is also stored as a row in a digital library index class as a collection of attributes and references to related content entities and containers. As the user selects desired objects for inclusion in a content object, the system arranges the objects hierarchically, e.g., into volumes, chapters and sections according to the order specified by the user. The system then creates a file object (e.g., a CBO) defining the content object that contains a list or outline of the container and noncontainer entities selected, their identifiers, order and structure. This file object is stored separately in the data repository. Content is moved in the content object by moving desired ones of the container and noncontainer content entity identifiers to new locations in the list or outline. This is achieved through a user interface by providing a mechanism for enabling a user to select a container or noncontainer (e.g., by title) to be moved and specify a target location for the content entity (e.g., by inserting the container or noncontainer title between other titles in the outline.)
