Asset Oriented Modeling (AOM)

- Algebra -


An algebra allows to derive new models from one or several existing models by using several basic operations.

When a model contains general constraints the operations listed below may not be computational: it will not always be possible to construct a model by formal means.
However, if we restrict the model's constraints to regular expressions or hedge regular expressions, it is possible to construct a new model using the operations listed below. For example, if we use XPath as a constraint language, we must avoid XPath functions that manipulate the content of nodes or nodesets such as substring(), concat(), sum(), avg(), etc.

The basic operations of an AOM algebra are:
