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.

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.)

Method and system for moving content in a content object stored in a data repository

A web-based system, method and program product are provided for creating a compilation of content stored in a data repository as a group of hierarchically related content entities, managing, displaying, and searching the content, then creating and exporting compilations of content for publication. The hierarchical data and associated metadata are preferably stored in a digital library that includes search support. A web-based user interface is provided for presenting a user with a plurality of selectable objects, each object representing a subset of the hierarchical data (e.g., chapter subsections, musical excerpts, video excerpts, etc.). The user then selects one or more of the objects for inclusion in a compilation (e.g., a custom textbook). Alternatively, the user may search the content by specifying search criteria through the interface. Additionally, the user may create new content, e.g., a new chapter or section, for inclusion in the final compilation by inputting user-provided material through the web interface. As the user selects desired objects for inclusion in a compilation, 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 compilation that contains a list or outline of the content entities selected, their identifiers, order and structure. This file object is stored separately in the data repository. The list or outline is presented to the user at the web interface as a table of contents, and may be edited through the interface. For example, the user may add content, delete content, or move content within and across containers. Editing the list or outline redefines the structure of the compilation. Once the user is satisfied with the organization of the compilation, it is submitted it for publication. The submitted compilation is then forwarded to an approval process and is accepted, rejected, or returned to the user with editorial comments appended by the editor.

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 added to the content object by adding a container or noncontainer identifier to the list or outline. This is achieved through a user interface by providing a mechanism for enabling a user to select a container or noncontainery (e.g., by title) and specify a target location for the container or noncontainer (e.g., by inserting the entity title between other entity titles on the outline.

This file object is stored separately in the data repository. User-provided content is added to the compilation by receiving input content and a target location in the content object from a user, assigning the content an identifier, storing the content in the data repository, and adding its identifier to the list or outline. As an aspect of the invention, a user interface is provided including mechanisms for enabling a user to input the content and specify a target location for the content (e.g., by inserting the title of the user-provided content entity between other entity titles on the outline. Both containers and noncontainers may be added in this fashion.

Method and system for adding user-provided content to a content object stored in a data repository

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.

Method and system for preventing mutually exclusive content entities stored in a data repository to be included in the same compilation of content

A data structure and method are provided for storing a content object stored (e.g., a custom compilation or prepublished work) as a group of hierarchically related content entities Each content entity is contained in a separate file object. An attribute file object corresponding to each content entity file object contains attributes pertaining to that entity. A list or outline containing container and noncontainer identifiers defines the content, order and structure of the content object. This list or outline is stored as a separate file object (e.g., a CBO or the PSF file of a prepublished work).

File structure for storing content objects in a data repository

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 removed from the compilation by removing the container or noncontainer identifier from 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 removed.

Method and system for removing content entity object in a hierarchically structured content object stored in a database

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. The content is hierarchical in nature. Accordingly, entities at each level of the hierarchy except the lowest are defined by &ldquo;containers&rdquo;. For example, in the case of textual content, the hierarchical structure of the data may include book containers, volume containers, chapter containers, and subsections (noncontainers) because they are at the leaf level of the hierarchy). As an aspect of the invention, the maximum size of a container may specified. For example, the volume size in a custom book is preferably determined using a threshold value defining maximum amount of content allowable for that container, and a procedure is provided for managing content entities and containers to maintain this maximum.
