+This README is for the W3C RDF Working Group's Turtle test suite.
+This test suite contains four kinds of tests:
+
+  132 Evaluation (rdft:TestTurtleEval) - a pair of an input turtle
+  file and reference ntriples file.
+
+  77 Positive syntax (rdft:TestTurtlePositiveSyntax) - an input turtle
+  file with no syntax errors.
+
+  78 Negative syntax (rdft:TestTurtleNegativeSyntax) - an input turtle
+  file with at least one syntax error.
+
+  4 Negative Evaluation (rdft:TestTurtleNegativeEval) - a pair of an
+  input turtle file and reference ntriples file. These tests have the
+  same properties as rdft:TestTurtleNegativeSyntax.
+
+The manifest.ttl file in this directory lists all of the tests in the
+RDF WG's Turtle test suite. Each test is one of the above tests. All
+tests have a name (mf:name) and an input (mf:action). The Evaluation
+tests have an expected result (mf:result).
+
+• An implementation passes an Evaluation test if it parses the input
+  into a graph, parses the expecte result into another graph, and
+  those two graphs are isomorphic (see
+  <http://www.w3.org/TR/rdf11-concepts/#graph-isomorphism>).
+
+• An implementation passes a positive syntax test if it parses the
+  input.
+
+• An implementation passes a negative syntax test if it fails to parse
+  the input.
+
+
+RELATIVE IRI RESOLUTION:
+
+The home of the test suite is <http://www.w3.org/2013/TurtleTests/>.
+Per RFC 3986 section 5.1.3, the base IRI for parsing each file is the
+retrieval IRI for that file. For example, the tests turtle-subm-01 and
+turtle-subm-27 require relative IRI resolution against a base of
+<http://www.w3.org/2013/TurtleTests/turtle-subm-01.ttl> and
+<http://www.w3.org/2013/TurtleTests/turtle-subm-27.ttl> respectively.
+
+
+CHARACTER ENCODING:
+
+The Turtle language uses UTF-8 encoding. The following tests include
+non-ascii characters:
+  localName_with_assigned_nfc_bmp_PN_CHARS_BASE_character_boundaries
+  localName_with_assigned_nfc_PN_CHARS_BASE_character_boundaries *
+  localName_with_nfc_PN_CHARS_BASE_character_boundaries *
+  labeled_blank_node_with_PN_CHARS_BASE_character_boundaries *
+  LITERAL1_with_UTF8_boundaries *
+  LITERAL_LONG1_with_UTF8_boundaries *
+  LITERAL2_with_UTF8_boundaries *
+  LITERAL_LONG2_with_UTF8_boundaries *
+
+Those marked with a * include characters with codepoints greater than
+U+FFFD and are thus expressed as a pair of surrogate characters when
+represented in UCS2.
