A method of operating a publish/subscribe message broker. A method in accordance with an embodiment includes receiving a message on a topic from a publisher, identifying the message as a start of a sequence of messages, transmitting the message to one or more existing subscribers to the topic, registering a new subscriber to the topic, receiving a further message on the topic from a publisher, and transmitting the further message to the one or more existing subscribers to the topic, but not to the registered new subscriber to the topic. Following the identifying of the message as a start of a sequence of messages, the message broker creates a new sub-topic corresponding to the sequence of messages and subscribes the one or more existing subscribers to the new topic. Any new messages received that relate to the sequence are published to the sub-topic and not the original topic. Any new subscribers to the topic are not subscribed to the sub-topic.

A method of creating an annotation to an email. The method includes: receiving an email; receiving a predefined user input; creating an annotation in response to the predefined user input, the annotation linked to the email; receiving a further user input; and defining a permission for the annotation according to the further user input, the permission defining user access to the annotation. When transmitting a second email as a response to the received email, the second email is linked to the annotation. The method further includes displaying at least a part of the annotation linked to the received email, for example when a user hovers over the email. The structure of the annotations allows the associating of the annotation with one or more further annotations.
摘要:
Subscribers connected to a publish/subscribe message broker receive messages on topic names to which they have subscribed. The subscribers receive any number of messages on each topic to which they have subscribed. When the broker receives a message on a second, pre-specified, topic, associated with a first topic, the broker removes any existing retained message related to the first topic. Thus any subsequent subscribers to the first topic do not receive the retained message when they subscribe, and thus do not receive out-of-date information. If, at a later date, a new message is published on the first topic subscribers will receive the new message if they are still subscribed.

摘要:
A method, system and computer program product for downloading an application over a network from a remote server to a client device, where the application includes a plurality of modules. A class for each module is created, where the class includes a constructor. A request to use a module of the application is received. Upon receiving the request, a determination is made as to whether the received request is a first request to use the module. If the received request is the first request to use the module, then the requested module is downloaded, the constructor is overwritten with the downloaded module and the constructor within the created class for the requested module is executed.
摘要:
A method for distributing a query, wherein the query comprises one or more sub-clauses, wherein each sub-clause comprises a triple pattern having three components for use with a distributed system, the method comprising the steps of: identifying each sub-clause; analysing three components of each sub-clause in accordance with one or more analysis rules in order to determine the proportion of values to variables; in response to the determination, testing the sub-clause against one or more execution rules, wherein the execution rules are associated with an order of processing of a sub-clause based on the proportion of values to variables; in response to the testing, generating a sub-query associated with a first sub-clause having the largest proportion of values to variables.
