Element Name

Description

pdoheader

The header contains a <request_type> element, which will carry the operation name. Each operation name has a specific request / response combination.

The following is a list of supported operation names:

• getPDO_fromInputList
• get_observationfact_by_primary_key
• get_patient_by_primary_key
• get_event_by_primary_key
• get_concept_by_primary_key
• get_observer_by_primary_key

request

The <request> is modeled as an object using a polymorphic approach. All operation specific request objects inherit a base RequestType object as shown in the object model diagram in the next section.

response

The <response> is also modeled as an object using a polymorphic approach. All operation specific response objects inherit a base PDOResponseType object containing a StatusType attribute as shown in the object model diagram in the next section.
