• a repository updating unit updating network address information in said data set including the first or second object identifier held by said repository to network address information indicating a site in which the first or second object which has moved in said network newly exists by designating a object identifier corresponding to said first or second object which has moved in said network when the first or second object moves in said network;
• an inter-site communication route establishing unit establishing an inter-site communication route between a third site and said second site where said second object exists after the movement of a first object based on said network address information held by said repository when said first object moves to the third site different from said first site in a state where an inter-object communication route is established between said first object at said first site and said second object;
• and
• an inter-object communication route reestablishing unit reestablishing an inter-object communication route between said first object and said second object using this established inter-site communication route and network address information held by repository.

An inter-object communication method for communicating between objects which are movable between a plurality of sites connected through networking, comprising the steps of:

• generating a first object which is an object set comprising a first communication object being an object including an access procedure having a function to directly access data and a first relay object being an object including an access process to said data by the access procedure in said communication object, in a first site of said network;
• generating a second object which is an object set comprising a second relay object having an access procedure for indirectly accessing said data possessed by said first communication object included in the first object through said network and a second communication object which accesses said data possessed by said first communication object included in said first object by the access procedure, through said network in a second site being a site in said network and different from or identical to said first site;
• updating network address information in data set including the first or second object indentifier to network address information indicating a site in which the first or second object which has noved in said network newly exists by designating a object identifier corresponding to said first or second object which has moved in said network when the first or second object moves in said network, the data set which is held by a repository, comprising object identifiers for identifying said first and second objects and network address information for indicating the addresses of the sites in said network where said first and second objects exist;
• and reestablishing communication between the first or second object which has moved in said network and another second or first object which has communicated through said network based on said network address information registered in said repository.

An inter-object communication method for communicating between a plurality of objects movable in a network through said network, comprising:

• generating a first MAG being an object set comprising an observable object being an object including an access procedure having a function to directly access data and a function to relay an access process to said data by the access procedure in said observable object, in a first computer of said network;
• generating a second MAG being an object set comprising a net observable object having an access procedure for indirectly accessing said data possessed by said observable object included in the first MAG through said network and an observer object which accesses said data possessed by said observable object included in said first MAG by the access procedure, through said network in a second computer being a computer in said network and different from or identical to said first computer;
• composing a repository being a server computer for holding a data set comprising MAG identifiers for identifying said first and second MAGs and network address information for indicating the addresses of the sites in said network where said first and second MAGs exist, in said network;
• allowing the first or second MAG to disconnect the communication with another second or first MAG communicating through said network and then to move in said network when the first or second MAG moves in said network;
• allowing the first or second MAG which has moved in said network to update network address information in said data set including the designated MAG identifier held by said repository to network address information indicating a computer in which the first or second MAG which has moved in said network newly exists by designating a MAG identifier corresponding to said first or second MAG which has moved in said network;
• and
• allowing the first or second MAG which has moved in said network to trigger said another second or first MAG which has communicated through said network and allowing said first or second MAG and said another second or first MAG to reestablish communication with each other by referring to said data set held by said repository corresponding to said first or second MAN and said another second or first MAG.
