A method, system and apparatus for tagging the seen/not-seen status of an instant message. A method for tagging a seen/not-seen status of a real time message can include receiving a real time message and presenting the real time message through a real time communications client disposed in a host client computing device. The environmental characteristics of the host client computing device can be inspected to determine whether the real time message has likely been reviewed. As such, if it is determined that the real time message has likely been reviewed based upon the inspected environmental characteristics, the real time message can be tagged as seen.

Tagging the seen/not-seen status of a real time message

Web services may be provided by creating an electronic record of a contract for a service provider to provide web services meeting a web service category definition at a web services hub of a service domain, and providing a web service to a service requestor from the service domain responsive to the electronic record of the contract. A plurality of ports operative to provide web services meeting the service category definition may be identified at the web service hub, and the web service may be provided to the service requester responsive to identification of the ports. For example, a plurality of ports may be identified by polling at least one web services node subordinate to the web services hub to identify at least one service provided by the node, and updating a description of a service category, e.g., a WSDL document, responsive to the polling. A plurality of levels of web services nodes may be polled using a coordinated polling interval scheme to create an updated service view for the service hub.

The present invention is a checkpoint processor configured for coupling to individual Web services through a Web services engine. The checkpoint processor can include checkpoint logic programmed to store checkpoint data for the individual Web service instance invocations. The checkpoint processor further can include restart logic programmed to restore the stored checkpoint data to a replacement for failed ones of the individual Web service instance invocations. Finally, the checkpoint processor can include cleanup logic programmed to removed the stored checkpoint data for concluded, non-failed ones of the individual Web service instance invocations. Notably, in a preferred aspect of the invention, logic can be included for identifying an asynchronous correlator for each one of the individual Web service instance invocations and for storing the asynchronous correlator in association with corresponding ones of the stored checkpoint data.

Dynamic inter-operability of nodes in services grids can be provided. In some cases, different version service nodes in a service grid can communicate using an inter-operability service to, for example, convert messages from one format associated with a version of a service node to another format associated with another version of a service node. Also, the message format may be converted from a current (e.g., newer) version of a node to another format which is compatible with an older version of a service node. The inter-operability service can be provided as a web service that is separate from the service nodes in the grid. The inter-operability service is associated with at least one of the service nodes in the grid and is available thereto via, for example, an administrative call by the associated service node.

A method for conferencing may include monitoring a status of participants in a conference and recording the conference in response to at least one participant being disconnected or exiting the conference. Another embodiment of the present invention may also include transmitting a re-invite signal to any participant that is disconnected or exits the conference in response to the participant being reconnectable or transmitting a request to rejoin the conference. A further embodiment of the present invention may include replaying a recording of the conference from a disconnect or exit time to a present time for each participant, that is involuntarily disconnected or exits the conference and communicates an indication of an intent to return, in response to a rejoining participant rejoining the conference.
