Distributed multi-user mashup session

A computer program product for presenting a multi-user mashup session across execution environments, the computer program product comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
• computer readable program code configured to,
• establish a mashup session based, at least in part, on a mashup application and execution environments of participants of the mashup session;
• maintain state data representative of at least a current view of the mashup session, wherein the computer readable program code being configured to maintain state data representative of at least the current view of the mashup session comprises the computer readable program code being configured to maintain at least one of a history of mashup actions performed in the execution environments that affect a state of the mashup session, a history of requests generated responsive to mashup actions performed in the execution environments during the mashup session, history of requests and corresponding parameter values submitted to the mashup application during the mashup session, one or more recent responses to requests submitted during the mashup session, and data generated by the mashup application responsive to actions performed with the mashup application in the execution environments during the mashup session;
• and
• maintain consistent views of the mashup session across the execution environments in accordance with the state data.

A computer program product for presenting a multi-user mashup session across execution environments, the computer program product comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
• computer readable program code configured to,
• generate a mashup session identifier for a mashup session based, at least in part on a mashup that uses a first set of services to generate results in response to requests submitted to the mashup;
• associate a plurality of participant devices with the mashup session identifier;
• establish connections with the plurality of participant devices;
• determine that a first of the plurality of participant devices modifies the mashup either to add a service for the mashup to use in conjunction with the first set of services for generating results in response to requests submitted to the modified mashup or to remove one of the first set of services;
• and
• maintain state data for the mashup session that represent at least a first current result generated by the mashup from use of the first set of services and that represent at least a second current result generated by the mashup as modified.

An apparatus comprising:

• a processing unit;
• a network interface;
• and
• a mashup session manager operable to,
• establish a mashup session based, at least in part, on a mashup application and execution environments of participants of the mashup session;
• maintain state data representative of at least a current view of the mashup session, wherein the mashup session manager being operable to maintain state data representative of at least the current view of the mashup session comprises the mashup session manager being operable to maintain at least one of a history of mashup actions performed in the execution environments that affect a state of the mashup session, a history of requests generated responsive to mashup actions performed in the execution environments during the mashup session, history of requests and corresponding parameter values submitted to the mashup application during the mashup session, one or more recent responses to requests submitted during the mashup session, and data generated by the mashup application responsive to actions performed with the mashup application in the execution environments during the mashup session;
• and
• maintain consistent views of the mashup session across the execution environments in accordance with the state data.
