Extensible service execution framework with data mapping architecture

A system, comprising:

• a device processor;
• and
• a memory coupled to the device processor and configured to provide the processor with instructions to:
• in response to a request from a first caller to invoke a software service, obtain an input data mapping expression that is based on a current context during execution;
• execute the input data mapping expression to map input data from a first caller context to a service context of the software service;
• store the mapped input data for use by the software service by setting one or more values in a data tree;
• and
• invoke the software service to process the mapped input data.

A non-transitory computer readable storage medium storing computer instructions for:

• receiving a request from a first caller to invoke a software service;
• automatically obtaining an input data mapping expression that is based on a first context tree of a first data model, and based on a current context during execution;
• evaluating the input data mapping expression to map input data from a first caller context to a service context of the software service;
• placing the mapped input data into a service data consumer object for use by the software service;
• and
• invoking the software service to process the mapped input data.
