6. An annotation filtering system comprising: a data scanning module, the data scanning module comprising at least one hardware device and configured to: receive a serial data stream input containing one or more computer files, the serial data stream input comprising data type descriptions of the one or more computer files and program elements corresponding to the data type descriptions; detect a first one of the data type descriptions in the serial data stream input; detect a first annotation for a first one of the program elements corresponding to the first one of the data type descriptions in the serial data stream input based on detecting the first one of the data type descriptions; determine if the first annotation and the program elements corresponding to the first one of the data type descriptions are of interest in response to detecting the first annotation; obtain an annotation value for the first annotation in the serial data stream input in response to determining the first annotation and the program elements corresponding to the first one of the data type descriptions are of interest; and generating output comprising the annotation value for the first annotation in response to determining the first annotation and the program elements corresponding, to the first one of the data type descriptions are of interest; and a data handling module, the data handling module to: receive the output from the data scanning module; and generate a data stream output containing the output.
9. The annotation filtering system of claim 6 , the data scanning module to obtain an annotated program element of the serial data stream input associated with the annotation value, and include the annotated program element in the output.
