Abstract: A client computing device identifies a model and data to be populated into the model of a webpage. The client computing device identifies a reference to a model definition resource and invokes a model definition resolver to identify the actual location of the model definition resource from a remote computer using the reference. The model definition resolver obtains the requested model definition resource from the remote computer using the actual location. The client computing device invokes one or more APIs to perform constraint enforcement on the identified data with respect to the identified model. Upon successful performance of constraint enforcement, the client computing device performs data binding for the data and the model and save the identified data, which may be further processed, into a repository of data models.
