What's Metadata?
Metadata is the information that we glean from an application during translation that describes the application and its data.
For example, we keep information about the datafiles used by each program and the fields within those files, including such information as datatype, size, platform-specific usage information, etc.
Another example would be the call graph for an application. That is, information about all of the calls to other programs and functions that a particular program makes.
All of this data is available, and can be formatted and exported to some other development tool.
We use this information to construct SQL database schemas and to perform data conversions when we migrate AS/400 applications, but you can use it to load into a CASE tool or other reengineering system
