Hi,
We noted it is possible to set values from AE/TD to a RM attribute
named “offset”
In the specs
<http://www.openehr.org/releases/RM/Release-1.0.3/docs/data_structures/data_structures.html#_event_class>
(looked at >1.0.1) it is not a regular attribute but a function which
returns a computed value using diff HISTORY.origin and EVENT.time
Note that this diff can also be a negative value – which doesn’t seem
to be supported by AE/TD or in instance data
An example ADL:
POINT_EVENT[at0002] occurrences matches {0..*} matches { -- Any
event
offset matches {
DV_DURATION matches {
value matches {|PT0.125S|}
}
}
Isn’t this weird?
it just checks that the value EVENT.offset, when called at runtime, is
within some range or equal to some value.
I would expect this to return a value if a valid ISO8601 time has been
entered for both HISTORY.origin and EVENT.time but not set as an
attribute directly.
if EVENT.offset doesn't return a valid value, its implementation has a bug.
