ABSTRACT:
A publisher-subscriber system includes a broker configured to receive and distribute at least one data stream from publishers to subscribers in accordance with subscriptions. An annotator/classifier is configured to annotate or classify the data stream by employing one or more additional stream-level attributes to create an annotated data stream wherein the annotated data stream applies the stream-level attribute to all messages therein. Subscribers can subscribe to the annotated data stream created by the annotator/classifier.
