Hello I found this article very interesting. John A New Specification for Managing Metadata Chuck Mosher, Java Developers Today's Internet-driven economy has accelerated users' expectations for unfettered access to information resources and transparent data exchange among applications. This exchange requires a deep knowledge of how each application, tool, or service structures and interprets the information it uses. The term metadata is used to describe both how this information is structured (its syntax) and what it means (its semantics). Unfortunately, most applications define metadata differently. Each uses slightly different programming structures, syntax, and semantics to model their metadata. These incompatibilities make it challenging for one application to discover and interact with the data maintained by another application. To overcome this hurdle, companies typically spend lots of developer time and money building hard-wired interfaces between applications so they can share data in sophisticated ways. This costly and ongoing effort is the result of a lack of common metadata -- or more specifically, a common model for creating metadata (a metamodel). This stifles the development of robust solutions to common business problems that require combining or using data from multiple, heterogeneous applications. http://developer.java.sun.com/developer/technicalArticles/J2EE/JMI/
