---------------------------------

             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).
