Abstract:
A method for representing a data subset of server data, comprising the steps of:identifying portions of the server data to be included in the data subset; providing declarations of value constraints and usage constraints with respect to at least some of the data of the data subset, the declarations for enforcing the value constraints and the usage constraints in subsequent renderings of the data subset on a client device; generating an instance of the data subset based on the identified portions and the declarations, the instance comprising the identified portions of the server data and the declarations; providing the instance of the data subset to a client device; rendering the data subset on the client device so as to enforce to the value constraints and the usage constraints; modifying data of the data subset rendered on the client device, subject to the value constraints and the usage constraints; and integrating client device modifications into the server data.
