Systems and/or methods for graph based declarative mapping

A method for mapping from one or more source information sets to one or more target information sets, the method comprising:

• storing a plurality of mapping ontologies in at least one memory, each mapping ontology from the plurality of mapping ontologies associating a first declarative expression with the one or more source information sets from which to read first information, and a second declarative expression with the one or more target information sets to which second information determined based upon the read first information is written;
• generating, by at least one processor communicably coupled to said memory and using a mapping graph creator, a mapping graph by parsing the plurality of mapping ontologies for the one or more source information sets to obtain the one or more target information sets, wherein the mapping graph having a plurality of nodes arranged according to an execution flow;
• and
• generating, by the at least one processor using a mapping graph executor, the one or more target information sets, by traversing, at runtime execution, the mapping graph according to the execution flow to evaluate mapping rules and the expression graphs, included in the mapping graph, to map from the one or more source information sets to the one or more target information sets,
• wherein multiple sources of various Multipurpose Internet Mail Extension (MIME) types can be accessed as the one or more source information sets, and
• wherein the mapping graph includes a plurality of nodes in which (a) the nodes representing ones of the plurality of mapping ontologies is a first set of nodes, (b) a second set of nodes represent respective conditional expressions, and (c) a connection between a first node and a second node, of the plurality of nodes, represent a respective parent-child relationship between the first node and the second node.

A non-transitory computer-readable storage medium having stored thereon computer program instructions that, when executed by a processor of computer having a memory configured to store a plurality of mapping ontologies, wherein each stored mapping ontology associates a first declarative expression with one or more source information sets from which to read first information and a second declarative expression with one or more target information sets to which second information determined based upon the read first information is written, causes the computer to perform operations comprising:

• generating, by at least one processor communicably coupled to said memory and using a mapping graph creator, a mapping graph by parsing the plurality of mapping ontologies for the one or more source information sets to obtain the one or more target information sets, wherein the mapping graph having a plurality of nodes arranged according to an execution flow;
• and
• generating, by the at least one processor using a mapping graph executor, the one or more target information sets by traversing, at runtime execution, the mapping graph according to the execution flow to evaluate mapping rules and the expression graphs, included in the mapping graph, to map from the one or more source information sets to the one or more target information sets,
• wherein multiple sources of various Multipurpose Internet Mail Extension (MIME) types can be accessed as the one or more source information sets, and
• wherein the mapping graph includes a plurality of nodes in which (a) the nodes representing ones of the plurality of mapping ontologies is a first set of nodes, (b) a second set of nodes represent respective conditional expressions, and (c) a connection between a first node and a second node, of the plurality of nodes, represent a respective parent-child relationship between the first node and the second node.
