Managing document annotations in a publish/subscribe system is described. A publishing system creates annotations of a document that include references to where the annotations are to be displayed; stores the annotations separately from the document; names an annotation set using tags; sets roles and permissions for use of the annotation set, including access permissions based on a time and/or location constraint of a subscribing user; and publishes the annotation set to a publish/subscribe broker for access by the subscribing users. A subscribing system subscribes a user to annotations of a document, wherein each annotation is separate from the document and includes reference to where the annotations are to be displayed. The subscribing system also defines a role of the subscribing user, wherein use permissions of the annotations by the subscribing user are controlled based on the role, including time and/or location constraints of the subscribing user.

Systems and methods for generating a visually enhanced image of a digital document are disclosed. In one example, a method includes receiving, by a computing device, a selection of an original document to be viewed by a user; obtaining, by the computing device, visual annotations for the original document from a remote computing device, wherein the visual annotations indicate one or more visual effects parameters associated with one or more pages of the original document; determining, by the computing device, visual effects to be applied to one or more pages of the original document based on the visual annotations; and applying the visual effects to render, by the computing device, a visually enhanced version of the original document for viewing by the user.

Control of messages in a publish/subscribe system is described. A publishing system creates a message for publishing to multiple subscribers via a broker system. The message and associated metadata are provided. The metadata defines control of the message and relates to control of publishing of the message, by the broker system, and/or control of use of the message, by a subscribing system. The message is published with the metadata. A broker system receives the message and analyses the metadata with respect to a subscriber. Based on the analysis, restrictions are applied to delivery of the message to the subscriber. A subscribing system receives the message and analyses the metadata with respect to the subscriber. Based on this second analysis, restrictions are applied to use of the message by the subscriber.

A method includes a workload management (WLM) server that receives a first CHECK WORKLOAD command for a workload in a queue of the WLM server. It may be determined whether the workload is ready to run on a WLM client. If the workload is not ready to run, a wait time for the workload with the WLM server is dynamically estimated. The wait time is sent to the WLM client. If the workload is ready to run, then a response is sent to the WLM client that workload is ready to run.
