Abstract
A method and apparatus in a data processing system for generating a metadata stream. An attribute call is received to set an attribute. In response, a first database is queried to determine whether the attribute call is present in the first database. The first database is updated in response to the attribute call being absent in the first database. In response to receiving a primitive call, an attribute call associated with the primitive is retrieved from the first database. A determination is made as to whether the attribute call associated with the primitive is present in a second database. The second database is; updated to include the attribute call associated with the primitive call in response to the attribute call associated with the primitive call being absent in the second database. The attribute call associated with the primitive call and the primitive call is placed in the metadata stream.
