Semantic weaving of configuration fragments into a consistent configuration

A network node comprising processing circuitry and memory, said memory containing instructions executable by said processing circuitry to integrate source models into a system configuration, whereby said network node is operative to:

• generate transformations according to a weaving model which specifies relations among metamodels of the source models and the system configuration, wherein the transformations, when executed, transform the source models into the system configuration including a plurality of target entities;
• generate, from the transformations, one or more integration constraints for each target entity to be created or modified by an operation of the transformations, wherein the integration constraints describe the relations specified by the weaving model;
• form system configuration constraints to include the integration constraints in addition to constraints of each source model;
• and
• execute the transformations to transform the source models into the system configuration to thereby generate the system configuration obeying the system configuration constraints.

A method for integrating source models into a system configuration, comprising:

• instantiating a server instance in a cloud computing environment which provides processing circuitry and memory for running the server instance, said server instance being operative to:
• generate transformations according to a weaving model which specifies relations among metamodels of the source models and the system configuration, wherein the transformations, when executed, transform the source models into the system configuration including a plurality of target entities;
• generate, from the transformations, one or more integration constraints for each target entity to be created or modified by an operation of the transformations, wherein the integration constraints describe the relations specified by the weaving model;
• form system configuration constraints to include the integration constraints in addition to constraints of each source model;
• and
• execute the transformations to transform the source models into the system configuration to thereby generate the system configuration obeying the system configuration constraints.
