XML remote procedure call (XML-RPC)

A method of invoking a service at a first machine, comprising the steps of:

• receiving at said first machine a service invocation request message generated at a second machine in compliance with a markup language-based message encoding wherein said message includes elements representing data items of at least one argument and associated with type labels selected from a group of type labels, said group including at least an array type label indicating that the corresponding element is an array element representing an n-dimensional array containing a plurality of data items, where n is an integer and n≧1, said message including at least one element associated with said array type label and representing a multi-level nested array where each element nesting level corresponds to a respective dimension of said array;
• and
• invoking said service in response to said message.

A method of invoking a service at a first machine, said method comprising the steps of:

• transmitting a service invocation request from a second machine;
• and
• receiving at said second machine a service invocation reply message in compliance with a markup language-based message encoding wherein said message includes elements representing data items of at least one argument and associated with type labels selected from a group of type labels, said group including at least an array type label indicating that the corresponding element is an array element representing an n-dimensional array containing a plurality of data items, where n is an integer and n≧1, said message including at least one element associated with said array type label and representing a multi-level nested array where each element nesting level corresponds to a respective dimension of said array.

A method of invoking a service at a first machine from a second machine, said method comprising the steps of:

• generating a service invocation request message at said second machine in compliance with a mark-up language-based message encoding wherein said message includes elements representing data items of at least one argument and associated with type labels selected from a group including at least an array type label indicating that the corresponding element is an array element representing an n-dimensional array containing a plurality of data items, where n is an integer and n≧1, said request message including at least one element associated with said array type label and representing an array of dimension n and further including an array label associated with said at least one element and requiring that all data items represented within said array have the same type as one another;
• and
• transmitting said service invocation request message from said second machine.

• receiving at said second machine a service invocation reply message in compliance with a markup language-based message encoding wherein said message includes elements representing data items of at least one argument and associated with type labels selected from a group including at least an array type label indicating that the corresponding element is an array element representing an n-dimensional array containing a plurality of data items, where n is an integer and n≧1, said reply message including at least one element associated with said array type label and representing an array of dimension n and further including an array label associated with said at least one element and requiring that all data items represented within said array have the same type as one another.

A method of invoking a service at a first machine from a second machine, comprising the steps of:

• generating a service invocation request message at said second machine in compliance with a markup language-based message encoding, wherein said message includes plural elements representing data items of at least one argument and associated with type labels selected from an encoding group having a predetermined number of members, including at least a first type label for designating an element containing lexical data, and a second type label for designating an element containing other elements associated with type labels selected from said group, and a third type label for designating an element containing other elements associated with type labels selected from said group;
• and
• transmitting said message.
