Hi,

Participation is not locatable. Is it going to be changed into locatable in future?

There is no possibility to get participation by atcode in data and determine which constraint describes it.

For example:

other\_participations cardinality matches {1..2; unordered} matches {  
PARTICIPATION occurrences matches {0..1} matches {  
function matches {  
DV\_CODED\_TEXT matches {  
defining\_code matches {[local::at0002]} – Doctor  
}  
}  
}  
PARTICIPATION occurrences matches {1..1} matches {  
function matches {  
DV\_CODED\_TEXT matches {  
defining\_code matches {[local::at0003]} – Nurse  
}  
}

There is a PR for this - [http://www.openehr.org/issues/browse/SPECPR-10](http://www.openehr.org/issues/browse/SPECPR-10)

In the meantime, you can add at-codes to PARTICIPATIONs, it is not illegal in archetypes.
