Abstract

A method and system for querying a Health Level 7 (HL7) data repository which stores entries in HL7 Reference Information Model (RIM) terminology across multiple HL7 domains. The method includes: receiving a query input to retrieve data from the repository, wherein the query input is in a query language, converting the query input to a RIM query, and retrieving data from the repository using the RIM query. The RIM query expresses the query input using RIM physical classes and RIM codes. The method also includes converting retrieved RIM instances from the repository to a domain readable format. Providing the data repository includes receiving data for input in the data repository, wherein the data for input is defined at a domain level as a domain instance, and converting a domain instance to a RIM instance and inputting the RIM instance in the data repository.

Claims

1. A method for querying a Health Level 7 (HL7) data repository, comprising:

providing a data repository which stores entries in HL7 Reference Information Model (RIM) terminology across multiple HL7 domains;

receiving a query input at a computer-based query application to retrieve data from the repository, wherein the query input is in a query language;

converting the query input to a RIM query;

retrieving data from the repository using the RIM query;

wherein any of said steps are implemented in either of computer hardware or computer software and embodied in a computer-readable medium.

2. The method as claimed in claim 1, wherein the RIM query expresses the query input using RIM physical classes and RIM codes.

3. The method as claimed in claim 1, including:

converting RIM instances from the repository to a domain readable format.

4. The method as claimed in claim 1, wherein a query input specifies one or more query domains.

5. The method as claimed in claim 1, wherein providing the data repository includes:

receiving data for input in the data repository, wherein the data for input is defined at a domain level as a domain instance;

converting a domain instance to a RIM instance; and

inputting the RIM instance in the data repository.

6. The method as claimed in claim 5, wherein converting a domain instance to a RIM instance expresses the domain instance using RIM physical classes and RIM codes with a clone name attribute that preserves the domain names.

7. The method as claimed in claim 6, wherein converting RIM instances to a domain readable format converts to domain instances using the domain name.

8. The method as claimed in claim 5, wherein converting a domain instance to a RIM instance includes translating all domain specific clone names to RIM class names and adding any default or fixed attributes.

9. The method as claimed in claim 5, wherein converting a domain instance to a RIM instance uses Model Interchange Format (MIF).

10. A computer program product for querying a Health Level 7 (HL7) data repository, the computer program product comprising:

a computer readable medium;

computer program instructions operative to;

provide a data repository which stores entries in HL7 Reference Information Model (RIM) terminology across multiple HL7 domains;

receive a query input to retrieve data from the repository, wherein the query input is in a query language;

convert the query input to a RIM query;

retrieve data from the repository using the RIM query;

wherein said program instructions are stored on said computer readable medium.

11. A method of providing a service to a customer over a network, the service comprising:

providing a data repository which stores entries in HL7 Reference Information Model (RIM) terminology across multiple HL7 domains;

receiving a query input at a computer-based query application to retrieve data from the repository, wherein the query input is in a query language;

converting the query input to a RIM query;

retrieving data from the repository using the RIM query;

wherein any of said steps are implemented in either of computer hardware or computer software and embodied in a computer-readable medium.

12. A system for querying a Health Level 7 (HL7) data repository, comprising:

a processor;

a data repository which stores entries in HL7 Reference Information Model (RIM) terminology across multiple HL7 domains;

a computer-based query input mechanism to retrieve data from the repository, wherein the query input is in a query language;

a first conversion mechanism for converting the query input to a RIM query;

a retrieval mechanism for retrieving data from the repository using the RIM query;

wherein any of said data repository, query input mechanism, first conversion mechanism, and retrieval mechanism are implemented in either of computer hardware or computer software and embodied in a computer readable medium.

13. The system as claimed in claim 12, including:

a second conversion mechanism for converting RIM instances from the repository to a domain readable format.

14. The system as claimed in claim 12, wherein a query input specifies one or more domains.

15. The system as claimed in claim 12, wherein the data repository includes:

a data receiving mechanism for input of data in the data repository, wherein data for input is defined at a domain level as a domain instance;

a third conversion mechanism for converting a domain instance to a RIM instance; and

an input mechanism for inputting the RIM instance in the data repository.

16. The system as claimed in claim 15, wherein the third conversion mechanism for converting a domain instance to a RIM instance expresses the domain instance using RIM physical classes and RIM codes with a clone name attribute that preserves the domain names.

17. The system as claimed in claim 15, wherein the second conversion mechanism for converting RIM instances to a domain readable format converts to domain instances using the domain names.

18. The system as claimed in claim 15, wherein the third conversion mechanism for converting a domain instance to a RIM instance includes translating all domain specific clone names to RIM class names and adding any default or fixed attributes.

19. The system as claimed in claim 15, wherein the third conversion mechanism for converting a domain instance to a RIM instance uses Model Interchange Format (MIF).
