  • openEHR XML-schemas - Release 1.0.1

    v22 v23  
    102102||VERSION<T>||only one type is used, namely VERSION. The subtype ORIGINAL_VERSION has its data attribute of type LOCATABLE (Version.xsd)||
    103103
    104 Multiple Inheritance
     104== Multiple Inheritance ==
     105
    105106There are a couple of places where multiple inheritance occurs in the openEHR reference model. In all cases, only one inheritance branch corresponds to subtyping in the substitutability (i.e. 'is-a') sense; the other branches are always 'facility'  or 'mix-in' inheritance. In the RM, classes inheriting in this way include rm.data_types.quantity.DV_INTERVAL and the rm.data_types.quantity.date_time classes. The latter inherit only interface, which has no visibility in XML-schema. For the former, the inheritance of Interval<T> by DV_INTERVAL<T> is done in the schema simply by direct inclusion, since the other branch of inheritance (of DATA_VALUE) is the one which must be visible to schema processing.
    106 Non-included classes and attributes
     107
     108== Non-included classes and attributes ==
     109
    107110The following RM classes are not included in the schema, as they are not needed in the data view: UID, UUID, INTERNET_ID, ISO_OID, and VERSION_TREE_ID.
    108111UID and its subtypes are not needed because OBJECT_ID has a value attribute of type string and its subtypes have a function that return a UID.
    109112Added attributes
    110113None in the current release.
    111 Conditional Rules
     114
     115== Conditional Rules ==
     116
    112117In instance data, LOCATABLE.archetype_details (of type ARCHETYPED) is only included when template_id exists, since the archetype_id attribute from ARCHETYPED is included by default as the value of LOCATABLE.archetype_node_id on archetype root-point LOCATABLE instances (top of a SECTION structure, OBSERVATION structure etc).
    113 XML Attributes and Elements
     118
     119== XML Attributes and Elements ==
     120
    114121XML attributes are not used with the exception of the LOCATABLE.archetype_node_id RM attribute, which is, from the point of view of RM classes, true meta-data. Making it an attribute allows archetype paths to be easily mapped to Xpaths.
