             Summary: TextMarker: Provide support for tree structures and parse 
trees in rule language
                 Key: UIMA-2758
                 URL: https://issues.apache.org/jira/browse/UIMA-2758
             Project: UIMA
          Issue Type: Bug
          Components: TextMarker
            Reporter: Peter Klügl
            Assignee: Peter Klügl


Manipulation of features which refer to annotations and matching on simple 
features is currently supported, but matching on the complex values of some 
feature is not. A first step can be something like (Type Person with feature 
"title" of type Annotation):

Person.title;

This rule matches on all annotations, which are values of features of 
annotations of the type Person.

This new language element can also be used for syntactic sugar when checking 
primitive feature values:

Person.begin=0 (A Person annotation, which starts a offset 0)

This can only be a first step towards supporting tree structures. Maybe there 
is no way around something for explicitly and directly referring to certain 
annotations (which is not possible right now, but is done by using the type).
