Re: "state" and "protocol" structures are mandatory, when defined?

[Thomas Beale <thomas.beale@oceaninformatics.com>]

In general questions like this can be answered by looking at any of:

• the relevant specifications: http://www.openehr.org/releases/1.0.2/roadmap.html , in this case, http://www.openehr.org/releases/1.0.2/architecture/rm/ehr_im.pdf
  
• the online UML - root link: http://www.openehr.org/svn/specification/TAGS/Release-1.0.1/publishing/architecture/computable/UML/uml_start_view.html  ; in this case, http://www.openehr.org/uml/release-1.0.1/Browsable/_9_0_76d0249_1109249648736_872559_12384Report.html
• the ADL Workbench schema, at http://www.openehr.org/svn/ref_impl_eiffel/BRANCHES/specialisation/apps/adl_workbench/app/rm_schemas/openehr_rm_102.dadl

Hi Alessandro,
items cardinality matches {0..*; unordered} is referred to "items" elements,
not to "protocol" element

This means we can have something like this:
<observation>
<data>
...
</data>
<protocol archetype_node_id="at0011" xsi:type="ITEM_TREE">
    <name>
        <value>*List(en)</value>
    </name>
</protocol>
<observation>

Is the section 
<protocol archetype_node_id="at0011" xsi:type="ITEM_TREE">
    <name>
        <value>*List(en)</value>
    </name>
</protocol>
mandatory, even if it doesn't have any items?
Looking at the archetype defintion, so it seems!

Leo,

as far as i can see the protocol section is not mandatory :

protocol matches {
ITEM_TREE[at0011] matches { -- lijst structuur
items cardinality matches {0..*; unordered} matches {

as you can see 0..* (means zero times until unbounded times), so not
mandatory

Hi all,
I have a doubt in interpretating the archetype definition when there are
"state" or "protocol" structure. For example, looking at "Blood
Pressure" in http://openehr.org/knowledge/, I'm wondering if "protocol"
structure is mandatory, as it seems looking at the archetype. If I don't
know any details about the protocol, do I have to insert an empty tag
<protocol> however?

Best regards
leo
