The XMI Toolkit 1.0 is the first release of XMI technology. The Toolkit is a Java component that converts UML information between Rational Rose Models and XMI-standard XML files. XMI can also generate new DTDs directly from your models. A Reference Implementation of XMI, with source code, is included.

FAQ

1. What's an example of how XMI may be used?
   
   Here's a common scenario. A business analyst makes a business model using an OOAD design tool using the UML (Unified Modeling Language) standard. The design is expressed in XMI and used by a software developer in his language IDE. Next, reports and documentation are published on the web, generated from the XMI. By accessing the design in XMI, database schemas and data warehouses may be created by database designers and business intelligence analysts.

   With XMI, users are able to focus directly on their roles, working as a team in an open, distributed environment. Users can employ the right products for each role and interchange their designs in XMI using the Internet.

   Using XMI opens up entirely new paths between tools, allowing customers to choose which tools work best in their distributed environment. A customer can choose modeling tools, IDEs, repositories, and databases based on each product's individual merits. Vendors and ISVs win because their best-of-breed solutions can work with the customer's extensive infrastructure.
   
   

2. How is XMI different from XML?
   
   XMI builds on XML by providing a standard way to convert objects into XML. XMI uses XML standards and applies usage conventions that facilitate reliable interchange of complex information between software applications.
