5.1.3. Knowledge Modeling

Modeling
The modeling objective is to share knowledge about resources through representations of the resources. Resources can be of any complexity.

Models
The modeled resources are typically defined in models.

Views
Views of the models are projected from different viewpoints, through different perspectives and notations, to viewing media, for study, evaluation, knowledge sharing, and discussion.

Considerations
These considerations, along with those associated with knowledge sharing, typically lead to further reviews of the models, further view projections, and further considerations.

Variability
The knowledge exchanged and the objectives of the knowledge sharing can vary greatly, between projects, models, views, viewpoints, and stakeholders, and each typically varies in time.

Conceptual Model
The resource representation process initially requires a conceptual model that is either and often both mental (e.g. in the human mind), and virtual (e.g. in the computers' mind).

Model Semantics
Typically that model uses a representation that is as close as possible to the model's essential semantics and as independent of notations as possible.

Perspectives
On the other hand, projected views, from any viewpoints, are projected through perspectives that define how the model view is to be represented, thereby typically also defining the notation to be used for the representation.

Viewpoints
It is interesting to note that viewpoints define the stakeholder position and interests about the model, defining what is to be viewed from the model.

Summary
In summary, models are conceptual and semantic representations of resources, viewpoints select what to view from models, perspectives determine how viewpoint selected model aspects are viewed or notated, and the model projection process combines and processes these factors to produce views of the models, for sharing knowledge about the modeled resources.
