## Post #1 by @Kohl_Christian

Dear all,

after parsing an archetype \(openEHR\-EHR\-OBSERVATION\.sample\_blood\_pressure\.v1\.adl \- see below\) which contains archetype slots I tried to use its AOM\-representation to identify archetypes which are allowed for these slots\.
I used the following code to display information on archetype slots:

private void printInfo \(ArchetypeSlot archetypeSlot\_, int iLevel\_\)

\{

    Iterator<Assertion> iterator\_;

    Assertion assertion\_;

    System\.out\.println\("\\n\\n\+ \[Level: " \+ iLevel\_ \+ "\] " \+ archetypeSlot\_\.path\(\)\);

    System\.out\.println\("\- Class : " \+ archetypeSlot\_\.getClass\(\)\.getName\(\)\);

    System\.out\.println\("\- RM Type : " \+ archetypeSlot\_\.getRmTypeName\(\)\);

    System\.out\.println\("\- Node\-ID : " \+ archetypeSlot\_\.getNodeID\(\)\);

    System\.out\.println\("\- Any allowed? : " \+ archetypeSlot\_\.isAnyAllowed\(\)\);

    System\.out\.println\("\- Required : " \+ archetypeSlot\_\.isRequired\(\)\);

    System\.out\.println\("\- Occurences : " \+ archetypeSlot\_\.getOccurrences\(\)\.getLower\(\) \+

                                " \- " \+ archetypeSlot\_\.getOccurrences\(\)\.getUpper\(\)\);

    // Includes

    System\.out\.println\("\- Includes :"\);

    if \(archetypeSlot\_\.getIncludes\(\) \!= null\)

    \{

        iterator\_ = archetypeSlot\_\.getIncludes\(\)\.iterator\(\);

           while \(iterator\_\.hasNext\(\)\)

        \{

            assertion\_ = \(Assertion\)iterator\_\.next\(\);

            System\.out\.println\(" > " \+ assertion\_\.getStringExpression\(\) \+

            " / " \+ assertion\_\.getTag\(\)\);

        \}

    \}

    else

    \{

        System\.out\.println\(" \- "\);

    \}

    // Excludes

    System\.out\.println\("\- Excludes :"\);

    if \(archetypeSlot\_\.getExcludes\(\) \!= null\)

    \{

        iterator\_ = archetypeSlot\_\.getIncludes\(\)\.iterator\(\);

           while \(iterator\_\.hasNext\(\)\)

        \{

            assertion\_ = \(Assertion\)iterator\_\.next\(\);

            System\.out\.println\(" > " \+ assertion\_\.getStringExpression\(\) \+

                                        " / " \+ assertion\_\.getTag\(\)\);

        \}

    \}

    else

    \{

        System\.out\.println\(" > \- "\);

    \}

\}

Unfortunately, I got the following output:

\+ \[Level: 2\] /protocol\[at0011\]/items\[at1025\]

\- Class : org\.openehr\.am\.archetype\.constraintmodel\.ArchetypeSlot

\- RM Type : CLUSTER

\- Node\-ID : at1025

\- Any allowed? : false

\- Required : false

\- Occurences : 0 \- null

\- Includes :

> null / null

\- Excludes :

> \-

Even though, the ADL\-file shows include infromation for the respective slot "assertion\_\.getStringExpression\(\)" returns NULL\.
How may I accees the required information \(in this example "/openEHR\-EHR\-CLUSTER\\\.device\\\.v1/"\)?

Best regards,

   Christian

Hi Christian,

Sorry for the delay. I am just back from a month vacation in China.

The stringExpression field of Assertion is not implemented yet. Instead you can find the specification for archetype_slot in the expression field, which is of ExpressionItem type.

You can look at the testcase for archetype slot parsing (adl-parser/src/test/java/se/acode/openehr/parser/ArchetypeSlotTest.java) to find out how to inspect the details of an ExpressionItem.

Hope this helps.

Hi again,

I just implemented the proper stringExpression support in assertion parsing (archetype_slot is kind of assertion in ADL).

I also updated the testcase to reflect this change, which you can find at adl-parser/src/test/java/se/acode/openehr/parser/ArchetypeSlotTest.java

Cheers,
Rong
