Hello Margit,

Thank you very much for trying out the AG toolkit.  Assuming that you have
python, I've written a simple example of using the AG library from python.
The following python code uses the most basic functions in the AG library.
For the explanations of all available functions in the API, please refer to
the IDL API specification of the AG library:
http://www.ldc.upenn.edu/AG/doc/idl/ag-1.0.idl. Also, there are some more
examples (in C++, but the same things can be done in python) in the
demo subdirectory of the aglib distribution.

Regards,

# import the ag module
import ag

# create an AGSet, a timeline and an AG 
AGSetId = ag.CreateAGSet("sample")
timelineId = ag.CreateTimeline(AGSetId)
AGId = ag.CreateAG(AGSetId, timelineId)

# create three anchors
anchor1 = ag.CreateAnchor(AGId)
anchor2 = ag.CreateAnchor(AGId)
anchor3 = ag.CreateAnchor(AGId)

# create three annotations
annotation1 = ag.CreateAnnotation(AGId, anchor1, anchor2, "word")
annotation2 = ag.CreateAnnotation(AGId, anchor2, anchor3, "word")
annotation3 = ag.CreateAnnotation(AGId, anchor2, anchor3, "misc")

# set offsets of some of the anchors
ag.SetStartOffset(annotation1, 1.00)
ag.SetEndOffset(annotation1, 2.00)

# set features to an annotation
ag.SetFeature(annotation1, "English", "cat")
ag.SetFeature(annotation1, "Japanese", "neko")

# examples of accessing & printing information in an AG
print "The features associated with annotation1 are:",  
print ag.GetFeatureNames(annotation1)
print

print "The ID of the start anchor of annotation1 is:",
print ag.GetStartAnchor(annotation1)
print

print "The IDs of annotations starting with the end anchor of annotation1 are:"
print ag.GetOutgoingAnnotationSet(ag.GetEndAnchor(annotation1))
print

print "An AIF file for the annotation graph above is:"
print ag.toXML(AGId)
