Abstract: A system (100) and method (200) for general notification of newly-acquired information by: subscribing (230) an indexing service (124; 128) to a broker (140) for a predetermined selection of information stored on an object server (110); and producing related information associated with the information stored on the object server, and publishing (220) the related information to the broker (140) for use in retrieval of the stored information from the object server. The related information preferably comprises metadata and tokens, and the indexing service the metadata for indexing and if the metadata is not relevant to its level of indexing uses the tokens to retrieve a copy of the related information for further analysis. This provides a combination of anonymous publish/subscribe technology to integrate otherwise centralised indexing and object storage, allowing content to be “pushed” to end user clients (130).
