+from gentestutils import genTestUtils
 
-# Current code status:
-#
-# This was originally written for use at
-# http://philip.html5.org/tests/canvas/suite/tests/
-#
-# It has been adapted for use with the Web Platform Test Suite suite at
-# https://github.com/w3c/web-platform-tests/
-#
-# The W3C version excludes a number of features (multiple versions of each test
-# case of varying verbosity, Mozilla mochitests, semi-automated test harness)
-# to focus on simply providing reviewable test cases. It also expects a different
-# directory structure.
-# This code attempts to support both versions, but the non-W3C version hasn't
-# been tested recently and is probably broken.
-
-# To update or add test cases:
-#
-# * Modify the tests*.yaml files.
-# 'name' is an arbitrary hierarchical name to help categorise tests.
-# 'desc' is a rough description of what behaviour the test aims to test.
-# 'testing' is a list of references to spec.yaml, to show which spec sentences
-# this test case is primarily testing.
-# 'code' is JavaScript code to execute, with some special commands starting with '@'
-# 'expected' is what the final canvas output should be: a string 'green' or 'clear'
-# (100x50 images in both cases), or a string 'size 100 50' (or any other size)
-# followed by Python code using Pycairo to generate the image.
-#
-# * Run "python gentest.py".
-# This requires a few Python modules which might not be ubiquitous.
-# It has only been tested on Linux.
-# It will usually emit some warnings, which ideally should be fixed but can
-# generally be safely ignored.
-#
-# * Test the tests, add new ones to Git, remove deleted ones from Git, etc.

+
+# Current code status:
+#
+# This was originally written for use at
+# http://philip.html5.org/tests/canvas/suite/tests/
+#
+# It has been adapted for use with the Web Platform Test Suite suite at
+# https://github.com/w3c/web-platform-tests/
+#
+# The W3C version excludes a number of features (multiple versions of each test
+# case of varying verbosity, Mozilla mochitests, semi-automated test harness)
+# to focus on simply providing reviewable test cases. It also expects a different
+# directory structure.
+# This code attempts to support both versions, but the non-W3C version hasn't
+# been tested recently and is probably broken.
+
+# To update or add test cases:
+#
+# * Modify the tests*.yaml files.
+# 'name' is an arbitrary hierarchical name to help categorise tests.
+# 'desc' is a rough description of what behaviour the test aims to test.
+# 'testing' is a list of references to spec.yaml, to show which spec sentences
+# this test case is primarily testing.
+# 'code' is JavaScript code to execute, with some special commands starting with '@'
+# 'expected' is what the final canvas output should be: a string 'green' or 'clear'
+# (100x50 images in both cases), or a string 'size 100 50' (or any other size)
+# followed by Python code using Pycairo to generate the image.
+#
+# * Run "python gentest.py".
+# This requires a few Python modules which might not be ubiquitous.
+# It has only been tested on Linux.
+# It will usually emit some warnings, which ideally should be fixed but can
+# generally be safely ignored.
+#
+# * Test the tests, add new ones to Git, remove deleted ones from Git, etc.

+Vocabulary Exercising Tools
+===========================
+
+The Web Annotation Vocabulary specification defines an ontology for
+portable annotations.  The tools in this directory, along with the
+sample files supplied, can be used to exercise the vocabulary
+"implementation" against various RDF processing engines.
+
+ruby-rdf
+========
+
+This directory contains a Ruby script that will evaluate the samples.  See
+the README.md file in that directory for more information.
+
+vocab-tester.py
+===============
+
+This python script exercises the vocabulary implementation using rdflib,
+rdflib-jsonld and pyld.  Note that this means your python environment must
+have those additional python modules installed in order to run the tests.
