The LCIM is used as descriptive and prescriptive form and it also make available of both metric of the degree of conceptual representation that exists between interoperating systems. In descriptive form LCIM is used to decrease the discrepancies in rating mobile apps based on content by suggesting a rating system that is completely based on interoperability. In the prescriptive form it receives information for app development, which allows producing apps with prominent level of interoperability.
