Subject Re: Support for UIMA arrays in Ruta

no, that's not possible. The CREATE accepts only type expressions, the 
GATHER integers and additionally integer lists (but these are referring 
to rule elements). A type list can only store type (expressions) and not 
the annotations themselves.

You must know that these actions were added due to some requirements in 
specific use cases/projects. Then, we tried to make them more generic 
and useful in also other use cases. There are plans to replace the 
extensive usage of type expression with a new construct referring 
annotations more generally...

Now to your problem :-)

The CREATE action (and similar actions) checks the type of the feature 
and collects all annotations of the type specified by the type 
expression. In case of the CREATE action: if the feature expects a 
single annotation, then the first annotation within the matched context 
is assigned. If the feature allows multple annotations (FSArray), then 
all annotations of the specified type within the matched context are 

This means you need only to use the type of the FSArray in the CREATE 
action. The actual selection of the annotations is controlled of their 
types, e.g., you maybe need to create new annotations of derived types.

Here a simple example (not tested):
DECLARE Container (FSArray tokens);
Sentence{-> CREATE(Container, "tokens" = Token)};

Here, an annotation of type Container is created for each Sentence and 
all Token annotations within this sentence are assigned to the feature 
"tokens", which is an FSArray.

I hope that helps :-)
