    摘要: There is provided a system and method for representing a data subset of server data. According to the method, a folder definition is generated for the data subset. The generation of the folder definition includes the substeps of identifying portions of the server data to be included in the data subset, generating declarations of value constraints and usage constraints with respect to at least some of the data of the data subset, and generating parameters to be supplied or selected by a user of a client device for further identifying the portions of the server data to be included in the data subset. The declarations are used for enforcing the value constraints and the usage constraints in subsequent renderings of the data subset on a client device. A folder instance is then generated based on the folder definition and parameters provided by a user of a client device or by default. The provided parameters (user provided or default) correspond to the generated parameters. The generation of the folder instance includes the substeps of generating the data subset from the identified portions of the server data and the parameters, and including the declarations of value constraints and usage constraints in the folder instance with the data subset.
