An application program, system and methods are configured to implement concurrent multiuser epistemological collaboration, that is, collaborative development of a digital knowledge model based on at least one epistemological “experience,” which is stored as a structured data entity containing information that can be personally perceived (typically viewed, read, observed) by multiple concurrent users of the application over a network. The users develop the digital knowledge model, by way of GIU interactions, comprising assertion entities and belief entities based on the experience and/or selected portions of the experience defined by focus entities; wherein each set of assertion entities is related as a child of a corresponding individual experience of the set of experience entities; and each set of belief entities is related as a child of a corresponding individual assertion of the set of assertion entities.
Please help me write a proper abstract based on the patent claims. CLAIM: 1.

The system according to claim 1 wherein the assertion set entity properties include its title, description, creating user, creation date and time, and model. 3. The system according to claim 1 wherein the belief set properties include its title, description, creating user, creation date and time, model, and the assertion set to which the belief set belongs. 4. The system according to claim 1 wherein: the belief entity properties include its creating user, creation date and time, target assertion, agreement with the assertion as a normalized positive (agreement) or negative (disagreement) magnitude, and confidence in the assertion indicated as a normalized positive (certain) or zero (uncertain) magnitude. 5. The system according to claim 4 wherein the belief properties further include a comment field for the creating user's explanation of their belief, and an identifier of the belief set to which the belief entity belongs. 6. The system according to claim 1 wherein the experience entity set of properties include its title, creating user, creation date and time, model, format kind, MIME (Multipurpose Internet Mail Extension) type, perceptual content URL (Uniform Resource Locator), “thumbnail” image URL for previewing the content, and a key-value mapping generic properties list. 7. The system according to claim 6 wherein the experience entity has at least one derivative experience subclass. 8. The system according to claim 7 wherein the derivative experience subclass has a format selected from a group of formats that includes include a text experience which reference a single block of textual characters, image experience which references a single flat bitmap or vector image, audio experience which references a single continuous auditory recording, video experiences which references a single continuous video recording, file experience which references a single computerized file of any type, and website experience which references a single network URL such as for an Internet website. 9. The system according to claim 7 wherein the derivative experience subclass has a format including a map experience which references a two-dimensional map. 10. The system according to claim 1, wherein properties of a focus entity include its creating user, creation date and time, model, format kind, originating parent experience, and dependent child experience. 11. The system according to claim 10, wherein the focus entity has at least one associated derivative focus format that inherits the properties of the focus entity type and defines a specific feature or subset of the focus entity. 12. The system according to claim 11, wherein the derivative focus format is selected from a set of derivative focus formats that includes a topic focus which represents a single textual topic or question of the parent experience, an index focus which represents a single real number index or linear position within the parent experience, a span focus which represents a real number start and end linear positions within the parent experience, a position focus which represents a two or three dimensional real number position within the parent experience 101, and a region focus 404 which represents a two or three dimensional region as a series of two or three dimensional real number positions (points) mapping a manifold surface through its maximum closed extents. 13. A database server coupled to a network for concurrent, multiuser communications and storing structured data to implement a digital knowledge model, the model including an experience-focus-experience sequence comprising: a parent experience entity; a focus entity linking a specific portion or subset of the parent experience entity that includes an author, to a child experience entity; wherein the child experience entity comprises content associated with an author of the parent experience; an assertion entity associated with the said content; and a belief entity associated with the assertion entity, the belief including an indication of partial agreement and partial confidence in the assertion. 14. The database server of claim 13 wherein the parent experience entity is characterized by a set of properties including its title, creating user, creation date and time, model, format kind, MIME (Multipurpose Internet Mail Extension) type, perceptual content URL (Uniform Resource Locator), “thumbnail” image URL for previewing the content, and a key-value mapping generic properties list. 15. A machine-readable, non-volatile memory storing an application program including instructions executable by a processor to implement a graphical user interface that displays: a client window containing a user list showing the current room's users; a menu bar providing for selection and creation of a knowledge model, an assertion set, and a belief set, as well as the creation of new root experiences; and a model graph based on the model. 16. The machine-readable, non-volatile memory of claim 15 wherein the model graph display provides an interactive graphical display of a relationship between the model components including experiences, focuses (shown as a labelled edge), assertions, and beliefs. 17. The machine-readable, non-volatile memory of claim 15 wherein the display further includes a detail panel 1305 that provides a form for viewing and editing specific components of the model. 18. The machine-readable, non-volatile memory of claim 15 wherein the application is further configured for communication over a network to update the stored model responsive to remote client-machine interactions and update user interface displays so that a user can input a reaction to an update provided by another user, thereby enabling users to concurrently articulate, explore, and critically examine their own and each other's views and beliefs associated with specific experiences reflected in the experience entities of the model. 19. The machine-readable, non-volatile memory of claim 18 wherein the knowledge model is represented as a software entity having a set of properties including its title, creating user, creation date and time, model, format kind, MIME (Multipurpose Internet Mail Extension) type, perceptual content URL (Uniform Resource Locator), “thumbnail” image URL for previewing the content, and a key-value mapping generic properties list. 20. The machine-readable, non-volatile memory of claim 19 wherein the experience entity has at least one derivative experience subclass, the derivative subclass having a format selected from a group of formats that includes include a text experience which reference a single block of textual characters, image experience which references a single flat bitmap or vector image, audio experience which references a single continuous auditory recording, video experiences which references a single continuous video recording, file experience which references a single computerized file of any type, and website experience which references a single network URL such as for an Internet website.
