testcases.turtle.tests-ttl-w3c-20131121.README Maven / Gradle / Ivy

This README is for the W3C RDF Working Group's Turtle test suite.
This test suite contains three kinds of tests:

  Evaluation (rdft:TestTurtleEval) - a pair of an input turtle file
  and reference ntriples file.

  Positive syntax (rdft:TestTurtlePositiveSyntax) - an input turtle
  file with no syntax errors.

  Negative syntax (rdft:TestTurtleNegativeSyntax) - an input turtle
  file with at least one syntax error.

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
  ).

• 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 .
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
 and
 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.
