Yes, that seems be another possible interpretation of the specs. So, it could be ISO8601_DURATION with a possible C_DURATION constraint underneath. Or it could be a STRING with a possible C_STRING constraint underneath.
Semantically, it seems to be pretty much the same (because of the invariant), but syntactically it matters for anybody or a tooling having to deal with this. I prefer it to be the first, I think, because it is clearer, and from what I understand this is your and Heath’s preference of what it should(!) be as well. But for now, looking at the specs, it clearly says String [with an invariant]…so it seems that that is what it needs to be changed to? This includes changing the C_DURATION underneath to a C_STRING as well, I would assume across the various tools. I just wonder why it was modelled that way in the specs (was it just an oversight, or is there a good reason such as that Duration is not (usually) an inbuilt datatype) Cheers Sebastian From: pazospa...@hotmail.com [mailto:pazospa...@hotmail.com] Sent: Donnerstag, 17.

Sent from my LG Mobile ------ Original message------ From: Sebastian Garde Date: Tue, Mar 15, 2016 09:36 To: For openEHR technical discussions; Subject:rm_type_name for the DV_DURATIONs primitive object in XML Dear all, There are a differences in how the Template Designer and how CKM construct the XML for a DV_Duration: Take this snippet (from http://openehr.org/ckm/#showArchetype_1013.1.123_XML ) <children xsi:type="C_COMPLEX_OBJECT"> <rm_type_name>DV_DURATION</rm_type_name> <occurrences> <lower_included>true</lower_included> <upper_included>true</upper_included> <lower_unbounded>false</lower_unbounded> <upper_unbounded>false</upper_unbounded> <lower>1</lower> <upper>1</upper> </occurrences> <node_id /> <attributes xsi:type="C_SINGLE_ATTRIBUTE"> <rm_attribute_name>value</rm_attribute_name> <existence> <lower_included>true</lower_included> <upper_included>true</upper_included> <lower_unbounded>false</lower_unbounded> <upper_unbounded>false</upper_unbounded> <lower>1</lower> <upper>1</upper> </existence> <children xsi:type="C_PRIMITIVE_OBJECT"> <rm_type_name>DV_DURATION</rm_type_name> <occurrences> <lower_included>true</lower_included> <upper_included>true</upper_included> <lower_unbounded>false</lower_unbounded> <upper_unbounded>false</upper_unbounded> <lower>1</lower> <upper>1</upper> </occurrences> <node_id /> <item xsi:type="C_DURATION"> <pattern>PMWD</pattern> <range> <lower_unbounded>true</lower_unbounded> <upper_unbounded>true</upper_unbounded> </range> </item> </children> </attributes> </children> What is the correct rm_type_name for C_PRIMITIVE_OBJECT here (in old red above)? Is it “DV_DURATION” as the Java Ref Impl uses or is it simply “DURATION” (both for reason I don’t really understand) or should it maybe be “String” or “ISO8901_DURATION” as http://openehr.org/releases/trunk/UML/#Architecture___18_1_83e026d_1433773264460_352968_7042 and/or http://openehr.org/releases/trunk/UML/#Architecture___18_1_83e026d_1422968609347_115062_25681 describe. Frankly I am confused, but I hope that someone can enlighten me here? Cheers Sebastian
