Abstract
An XML representation of the metadata for objects in a database system. The XML representation is called SXML. The SXML representations of two objects that belong to the same class of objects may be compared to produce a difference representation that shows the differences between the objects. Database commands that will create or alter objects may be produced from the difference representation, as well as an XML representation of the database commands. In addition to being comparable, SXML representations have the characteristics that a given property of the metadata is expressed in only one way in the representation, that SXML does not describe properties that belong only to particular instances of the object described by the metadata, that SXML describes only properties that the user can specify when creating an object, and that SXML is easy for humans to read, understand, and write.
