Web services of transformation data based on OpenEHR into Health Level Seven (HL7) standards

To minimize the differences between the data standards of Healthcare Information System (HIS) then it needs a system that is using a standardized international health among others OpenEHR health information standards from Europe and the HL7 health information standards comes from America. In OpenEHR, all of a patient's health data to be stored in the history of life, are independent vendors, and centered on one person. HL7 (Health Level Seven) is one of many ANSI standard which has been accredited by SDO (Standards Developing Organizations). HL7 does not develop healthcare or hospital software application, but it only develops the concepts, methodology, specification, and standard, so exchanging data among different application is possible to be done. Conceptually, this exchanging data method is known as Electronic Data Interchange (EDI). As an embodiment to provide standardization of HIS based on Health Level Seven, it is achieved by building a web service of HIS based on HL7. This web service will be expected to make a standardizing the health data based on HL7, so that the process of data exchange or health information becomes more structured.
