A task oriented data model for an object oriented development tool. The data model comprises a task oriented structure which mirrors the task tree embodied in the user interface of the object development tool. The object development tool exports the data model as a document expressed in meta data language such as XML. The XML data model document comprises a series of data elements which are arranged according to a meta data model to mirror the user interface task tree. The meta data model is implemented in XML as a Document Type Definition and comprises containment relationships defined by XML constructs. The task oriented data model provides granularity for exporting and importing data elements, and also facilitates locating data elements of interest in the data model.
