Representing web data into a machine understandable format is a curtail task for the next generation of the web. Most of solutions are relying on ontologies. However, there are many problems of using ontologies. This paper proposes an approach to represent dynamic web page contents retrieved from underlying database, into Concept Description Language (CDL) semantic format. This format does not depend on ontologies. However, CDL describes semantic structure of web content based on a set of predefined concepts and semantic relations. A prototype of the proposed approach is implemented to show visibility of the proposed approach.
