System and method for generating data resources in a processing system
Systems and methods, as well as devices, are described for clinical resource generation. CCDA documents that include clinical information and observations are utilized to generate FHIR model instances that are specific to the CCDA documents. Path definitions are assigned for each information-value pair the CCDA documents that define mappings between the information-value pairs and objects of FHIR model instances. Objects for the instance models are created, and values are provided to the objects representative of the information-value pairs. Groups of objects are provided in FHIR resource bundles that are stored in a database which may be queried against to provide specific FHIR resources upon request. Requests for clinical information may be used to trigger the generation of the FHIR resource bundles.

assigning path definitions for each of the at least one information-value pair that define mappings between the at least one information-value pair in the object model document and objects of an ontology model having a second standard format, the second standard format being FHIR (Fast Healthcare Interoperability Resources), and the ontology model having a hierarchical structure based on attributes and dependency associations between objects therein;
generating an instance model of the ontology model that is representative of the document and that is in the second standard format based on the path definitions by:
linking the defined mappings to codes of the ontology model by traversing paths within the hierarchical structure of the ontology model specified by the path definitions;
creating the objects for the instance model at endpoints of the paths that are traversed; and
providing values to the objects for the instance model corresponding to each of the at least one information-value pair based on said linking; and
responsive to receiving an object model query for at least one of the values, applying the object model query against the instance model that is generated, based on the attributes and the dependency associations of the objects, to generate a query result that comprises the at least one of the values.
