Abstract:
A method in a data processing system for generating a metadata stream, the method comprising the data processing system implemented steps of:receiving an attribute call to set an attribute; querying a first group of attributes to determine whether the attribute call is present and identical within the first group of attributes; updating the group of attributes in response to an absence of a determination that the attribute call is present and identical to an attribute call in the first group attributes; receiving a primitive call; retrieving an attribute associated with the primitive from the first group of attributes; determining whether the attribute call associated with the primitive is present and identical to an attribute call in a second group of attributes; updating the second group of attributes to include the attribute call associated with the primitive call in response to an absence of a determination that the attribute call associated with the primitive call is present and identical in the second group of attributes; and placing the attribute call associated with the primitive call and the primitive call in the metadata stream.
