Building block types, bind and prescribe the objects to be used and the structures formed with objects. Refine problem objects using basic building blocks of Hypertext. This activity completes labor undertaken during activities 1 and 2. Identified objects must be expressed by way of basic building blocks of the hypertext system. Refine problem structures.
Evaluation is done, for establish how to link problem objects.
This activity considers rigorously building blocks details of the Hypertext System, because the final product of this activity is the logical model and the physical model of the problem. Establishing policies for defining the possible link types for structure problems and object problems, when data is being added to data model. In this case it is necessary that users know the object schema, that in this particular case is the same data model. In traditional information systems the data schema does not concern users, but in the case of multimedia information systems, some insight about the data schema must be supplied to users. Notation A particular Notation is proposed to use troughout the activities for building the problem models.
