Hi Igor,
AQL allows string RegEx pattern in an archetype predicate. RegEx pattern
needs to be enclosed by '{/' RegEx '/}'. For your scenario, the AQL may
include something like:
...[openEHR-EHR-CLUSTER.a.v1]
/items[{/openEHR-EHR-CLUSTER\.b(-[a-zA-Z0-9])*\.v1/}] /
items[at0003]/value
Or something like the one below. The expression below is for retrieving both
element [at0003] instance value and the specialization of this element if
the specialized archetype has specialization of element at0003 (such as
at0003.1):
...[openEHR-EHR-CLUSTER.a.v1]
/items[{/openEHR-EHR-CLUSTER\.b(-[a-zA-Z0-9])*\.v1/}] /
items[{/at0003([0-9.]+)*/}]/value
Hope this helps. Please let me know if you have more questions.
Regards,
Chunlan

Subject: AQL query to archetype and it's specializations in slot
Hi!
I have an archetype 'A' with slot named 'Slot In A'.
There is constraint for possible archetypes for this slot: "B and
specializations of B".
I know that in archetype B (and in all of it's specializations) there is
field 'at0003' named 'Field In B'
I know only about B and particular clients has their own independent
specializations 'B-spec'.
Now I want to build a query like this:
...[openEHR-EHR-CLUSTER.a.v1] /items[openEHR-EHR-CLUSTER.b.v1] /
items[at0003]/value
And I want something like "Archetype of this type and it's specializations"
instead of just this "items[openEHR-EHR-CLUSTER.b.v1]".
The question is: how :-)

Igor Lizunov
