On the Representation and Use of Metadata
نویسنده
چکیده
Metadata is the key to component-based programming. Metadata can provide additional information for every type and member defined in the program code in a languageneutral fashion. Moreover, metadata facilitates the interaction of a component with another component or application. In this position paper, we analyze the expressive power of custom attributes, one of the most innovative features of the .NET framework. We argue, that custom attributes, as built-in language abstractions, provide a way to represent both functional and non-functional properties of components. Furthermore, using the .NET reflection mechanism, custom attributes can be used to establish new business models, which have never been possible before.
