Abstract
This document describes the RDF Test Cases deliverable for the
RDF Core Working
Group as defined in the Working Group's Charter.
One of the deliverables specified in Charter of
the RDF Core Working
Group is: a set of machine-processable test
cases corresponding to technical issues addressed by the
Working Group. This document describes the test cases that fulfill that
deliverable but it does not contain the test cases themselves. The
test cases are available at http://www.w3.org/2000/10/rdf-tests/rdfcore/.
The RDF Interest
Group and other members of the RDF community have identified
issues/ambiguities in the [RDFMS] Specification and the [RDF-SCHEMA] Candidate Recommendation.
These issues have been collected and categorized in the RDF Core Working Group Issue
Tracking document. The RDF Core Working Group uses this issue
list to guide its work. The issues list is a working document; it
is updated as new issues are identified. It is updated as the
Working Group makes decisions as documented in the Attention
Developers section of the document.
The complete specification of RDF consists of a number of
documents:
1.1. Scope
A comprehensive and complete test suite for RDF should cover all
of the rules in the Formal Grammar
for RDF. The Working Group, however, is not chartered to
deliver such a test suite but rather to create test cases for the
issues the Working Group addresses (when applicable). Although the
Working Group will not create test cases for some grammar rules
(e.g. rule [6.1]), if such test cases are donated to the W3C the
Consortium may add such test cases to this set of test cases.
1.2. RDF
Errata
The RDF
Errata documents known errors in [RDFMS]. Since errata are considered
normative changes to a W3C Specification and Working Group
decisions are not normative until a specification is a W3C
Recommendation, none of the decisions made by the RDF Core Working
Group have (to date) been reflected in the errata.
The Test Case Repository
[REPOSITORY]
contains subdirectories, each containing test cases devoted to
a single issue. Each directory contains a manifest file
describing the tests in that directory. Where an issue originated
with the RDF Issue Tracking process
[ISSUES], the
manifest will indicate this fact.
The Test Case Repository contains ZIP files of all Approved test
cases
[APPROVED] as well as
a ZIP archive of all Approved and Not Approved test cases
[FULLTESTS]
The Manifest file
[MANIFEST]
contains a machine-readable manifest of the test cases.
The format of this file is described below.
The manifest file
[MANIFEST]
contains a machine-readable description of the test cases in
RDF/XML. Care has been taken to ensure that this file
follows a simple format to assist in machine-processing the test
cases.
The file consists of a simple header
[MANIFEST-HEAD],
individual descriptions of the test cases, and a closing footer
[MANIFEST-TAIL].
The test cases are divided into the following categories:
- Positive Parser Tests
-
These tests consist of one (or more) input documents in RDF/XML
as is revised in [RDF-SYNTAX]. The expected result
is defined using the N-Triples syntax
(Section 3). A parser is considered to pass the test if it
produces a graph
equivalent to the graph described by the N-triples output
document, according to
the definition of graph equivalence given in [RDF-CONCEPTS]. Where the
input document(s) are legal RDF/XML, but a warning may be
generated, this is indicated in the test manifest.
<test:PositiveParserTest rdf:about="http://w3.example.org/test001">
<test:issue rdf:resource="http://w3.example.org/rdf-tracking/#example1" />
<test:status>APPROVED</test:status>
<test:approval rdf:resource="http://rdfcore.example.org/archives/001.html" />
<test:description>
This is a simple positive parser test example.
</test:description>
<test:inputDocument>
<test:RDF-XML-Document rdf:about="http://w3.example.org/test001.rdf" />
</test:inputDocument>
<test:outputDocument>
<test:NT-Document rdf:about="http://w3.example.org/test001.nt" />
</test:outputDocument>
<test:warning>Some parsers may produce a warning when running this test</test:warning>
</test:PositiveParserTest>
- Negative Parser Tests
-
These tests consist of one input document. The document is not
legal RDF/XML. A parser is considered to pass the test if it
correctly holds the input document to be in error.
<test:NegativeParserTest rdf:about="http://w3.example.org/error001">
<test:issue rdf:resource="http://w3.example.org/rdf-tracking/#example1" />
<test:status>APPROVED</test:status>
<test:inputDocument>
<test:RDF-XML-Document rdf:about="http://w3.example.org/error001.rdf" />
</test:inputDocument>
</test:NegativeParserTest>
- Positive Entailment Tests
-
These tests are specified by one or more premise documents (in
RDF/XML or N-Triples) together with a single conclusion
document. In addition, the rules used for determining
entailment are specified by test:entailmentRules elements. If
the following is present
<test:entailmentRules rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#" />
then the test succeeds if the entailment holds according to the
rules of RDF-entailment as specified in [RDF-SEMANTICS]. If the following
two elements are present
<test:entailmentRules rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#" />
<test:entailmentRules rdf:resource="http://www.w3.org/2000/01/rdf-schema#" />
then the test succeeds if the entailment holds according to the
rules of RDFS-entailment as specified in [RDF-SEMANTICS].
For test cases that use simple entailment, the following marker
is used:
<test:entailmentRules rdf:resource="http://www.w3.org/2000/10/rdf-tests/rdfcore/testSchema#simpleEntailment" />
<test:PositiveEntailmentTest rdf:about="http://w3.example.org/rdfs-domain-and-range/conjunction-test">
<test:description>
This test demonstrates the conjunctive nature of range and domain.
</test:description>
<test:entailmentRules rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#" />
<test:entailmentRules rdf:resource="http://www.w3.org/2000/01/rdf-schema#" />
<test:premiseDocument>
<test:NT-Document rdf:about="http://w3.example.org/rdfs-domain-and-range/test001.nt" />
</test:premiseDocument>
<test:premiseDocument>
<test:NT-Document rdf:about="http://w3.example.org/rdfs-domain-and-range/test002.nt" />
</test:premiseDocument>
<test:premiseDocument>
<test:NT-Document rdf:about="http://w3.example.org/rdfs-domain-and-range/test003.nt" />
</test:premiseDocument>
<test:conclusionDocument>
<test:NT-Document rdf:about="http://w3.example.org/rdfs-domain-and-range/test004.nt" />
</test:conclusionDocument>
</test:PositiveEntailmentTest>
According to [RDF-SEMANTICS], a premise document
that contains a semantic error with respect to any constraints
imposed by the entailment rules selected will be false in any
interpretation
(and hence entail anything).
Support for such situations is provided by the manifest
format by declaring an premise or conclusion pseudo-document as
follows:
<test:conclusionDocument>
<test:False-Document/>
</test:conclusionDocument>
By convention, such a pseudo-document is said to come out
false under any interpretation.
- Negative Entailment Tests
-
These tests are specified using a similar structure to the
Positive Entailment Tests, with the
<test:NegativeEntailmentTest> element used instead of the
<test:PositiveEntailmentTest>.
The test is failed if the conclusion can be drawn from the
premises using the rules of RDF- or RDFS-entailment. The test is
considered to be passed when it can be conclusively
demonstrated that the conclusion cannot be so drawn. In practice, the
test may be considered to be passed when a thorough attempt to fail
the test is unable to achieve failure.

<test:status>PENDING</test:status>
<test:approval rdf:resource="http://rdfcore.example.org/Archives/Public/w3c-rdfcore-wg/2002Feb/0476.html" />
<test:description>
RDF Core WG RESOLVED that a reified statement was a stating, not a statement.
The following entailment does not, therefore, hold.
</test:description>
<test:entailmentRules rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#" />
<test:entailmentRules rdf:resource="http://www.w3.org/2000/01/rdf-schema#" />

<test:conclusionDocument>

</test:conclusionDocument>
</test:NegativeEntailmentTest>
- Datatype-aware entailment tests
-
Entailment test cases may, in addition, require datatype
support. Such a requirement is indicated in the manifest by the
presence of the following test:entailmentRules element,
followed by zero or more test:datatypeSupport entries.
<test:entailmentRules rdf:resource="http://www.w3.org/2000/10/rdf-tests/rdfcore/datatypes#" />
<test:datatypeSupport rdf:resource="http://www.w3.org/2001/XMLSchema#integer" />
<test:datatypeSupport rdf:resource="http://dt.example.org/datatype#foo" />
For the purposes of the test suite, if a test case requires
datatype support for a set of datatypes, { T,
U, V, ... } then the following three pieces of
machinery are required:
- for any datatyped literal of the form
"aaa"^^<T> where T is
a supported datatype, it must be possible to determine if
aaa is a valid lexical form for that datatype;
and
- for any two datatyped literals of the form
"aaa"^^<T> and
"bbb"^^<U> with aaa
and bbb valid lexical forms of the supported
datatypes T and U respectively, it must be
possible to determine if those two literals denote the same
value. (Note that determining what that value is is
not explicitly required.)
- for any datatyped literal of the form
"aaa"^^<T> where T is
a supported datatype, and for some supported datatype
U, it must be possible to determine if the value
denoted by the literal is or is not a member of the value
space of U. (This last condition is required to
support the checking of range clashes.) Finally,
- For two supported datatypes T and U,
it must be possible to determine (possibly by simple fiat)
if T, considered as a class, is a subclass of
U, considered as a class.
- Miscellaneous Tests
-
This manifest entry is used to describe test cases that do not
fall into one of the earlier categories. It may have several
associated files, indicated in <test:document> elements.
<test:MiscellaneousTest rdf:about="http://w3.example.org/misc001">
<test:status>PENDING</test:status>
<test:description>
A serializer asked to output the graph described in the test001
document should raise an exception since it cannot be described using
RDF/XML.
</test:description>
<test:document>
<test:NT-Document rdf:about="http://w3.example.org/nonserializable/test001.nt" />
</test:document>
</test:MiscellaneousTest>
In addition, each test case description may have the following
common attributes:
-
The test:issue element contains a pointer to the
associated issue on the RDF Core Working Group
Tracking document. It may appear zero or more times.
<test:issue rdf:resource="http://www.w3.org/2000/03/rdf-tracking/#rdfs-no-cycles-in-subClassOf" />
-
The test:status element, if present, indicates the
status of the test according to RDF Core Working Group process. Only test
descriptions containing the following should be considered to
be approved by Working Group.
<test:status>APPROVED</test:status>
-
The test:approval element, if present, contains a
reference to the minutes of the RDF Core Working Group meeting where the
test case status was last changed.
<test:approval rdf:resource="http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2002Feb/0476.html" />
-
The test:discussion element, if present, contains a
pointer to other discussion surrounding this test case or the
associated issue. This element may appear multiple times.
<test:discussion rdf:resource="http://rdfcore.example.org/" />
-
The test:description element, if present, contains a
human-readable summary of the test case.
<test:description>
Text describing the test case goes here.
</test:description>
-
The test:warning element, if present, indicates that
while the test should pass, it may generate a warning. The
contents of the element provide a human-readable description of
the warning.
<test:warning> Text describing the warning goes here. </test:warning>
The test cases in the following table have been approved.
The test case repository contains test cases that have not been
approved. Such test cases are not enumerated in this document but a
list of them is available at
http://www.w3.org/2000/10/rdf-tests/rdfcore/allTestCases.html.
The test case manifest format was deliberately chosen to be a
simple, declarative description of the test cases. Parser tests can
be run in conjunction with simple tools such as ntc[NTC]. A parser should pass all the
positive parser tests, and reject all the negative parser tests.
Tools like Euler
[EULER]
have been used to run the entailment tests.
Due to the rules of entailment tests, a positive or negative
entailment test case with an empty conclusion document can be used
to illustrate semantic constraints associated with sets of
entailment rules.
The test cases have been created to illustrate the resolution of
particular issues on the RDF Issue
Tracking list. Consequently, test case results should always be
interpreted in conjunction with the resolution of the associated
issue and the description (if any) attached to the test case in the
manifest.
N-Triples is a line-based, plain text format for encoding an RDF
graph. It was designed to be a fixed subset of N3[N3] [N3-Primer] and hence N3 tools such as
cwm [CWM],
n-triples2kif [N-TRIPLES2KIF],
and Euler [EULER]
can be used to read and process it.
cwm can output this format when invoked as
"cwm -ntriples".
It is recommended, but not required, that N-Triples content is
stored in files with an '.nt' suffix to distinguish them from
N3.
The Internet media type / MIME type of N-Triples is text/plain
and the character encoding is 7-bit US-ASCII.
NOTE: N-Triples is an RDF syntax for
expressing RDF test cases and defining the correspondence
between RDF/XML and the RDF abstract syntax. RDF/XML
[RDF-SYNTAX]
is the recommended syntax for applications to exchange
RDF information.
An N-Triples document is a sequence of US-ASCII characters and
is defined by the ntripleDoc grammar term
below. Parsing it results in a sequence of RDF triples formed
from the subject, predicate and object
productions.
This EBNF is the notation used
in XML 1.0 second edition
These productions encode concepts defined in the
RDF Concepts and Abstract Syntax [RDF-CONCEPTS] working draft as follows:
N-Triples strings are sequences of US-ASCII character productions encoding [UNICODE] character
strings. The characters outside the US-ASCII range and some
other specific characters are made available by \-escape sequences
as follows:
Unicode character
(with code point u) |
N-Triples encoding |
| [#x0-#x8] |
\uHHHH
4 required hexadecimal digits HHHH
encoding Unicode character u
|
| #x9 |
\t |
| #xA |
\n |
| [#xB-#xC] |
\uHHHH
4 required hexadecimal digits HHHH
encoding Unicode character u
|
| #xD |
\r |
| [#xE-#x1F] |
\uHHHH
4 required hexadecimal digits HHHH
encoding Unicode character u
|
| [#x20-#x21] |
the character u |
| #x22 |
\" |
| [#x23-#x5B] |
the character u |
| #x5C |
\\ |
| [#x5D-#x7E] |
the character u |
| [#x7F-#xFFFF] |
\uHHHH
4 required hexadecimal digits HHHH
encoding Unicode character u
|
| [#10000-#x10FFFF] |
\UHHHHHHHH
8 required hexadecimal digits HHHHHHHH
encoding Unicode character u
|
where H is a hexadecimal digit:
[#x30-#x39],[#x41-#x46] (0-9, uppercase A-F).
This escaping satisfies the [CHARMOD] section Reference
Processing Model on making the full Unicode character range U+0
to U+10FFFF available to applications and providing only one way to
escape any character.
The absoluteURI production
encodes a Unicode string representing an
RDF URI references as specified in
[RDF-CONCEPTS].
These are encoded in N-Triples using
the escapes described in section Strings.

started.
The editors would also like to thank Jos DeRoo, of AGFA, for his
excellent work in the implementation of an RDF reasoner capable of
running the entailment test cases.
Thanks are also due to the RDF parser implementers who took the
time to run, and submit corrections to, our parser tests.

Added explicit simple entailment marker to entailment tests.
Reworded the pass and failure criteria for negative entailment tests according
to suggested wording from Pat Hayes.
Added test case for RDF/XML without an enclosing rdf:RDF
element (rdf-element-not-mandatory/test001).
Removed N-Triples reference to language tags and RFC3066, use
the RDF concepts definition. A language tag cannot start with a
digit.
Added test cases for intensional interpretation of datatypes.
Added test case: plain literals and xsd:string denotations overlap.
Editorial change. The caption on the test case table now makes
it clear that it refers only to the resolution of relative URLs
within the table.
Editorial change. Updated section 3. N-Triples
NOTE on the purpose of N-Triples to say it is used to map abstract RDF
syntax and RDF/XML.
Terminological change. Updated section 2.1. Organization
To use the more acceptable term, "graph equivalence".
Substantive change. Updated section 2.1. Organization
to include fourth condition for datatype support when
describing datatype entailment tests.
Editorial change. Updated references throughout to remove URLs from prose;
additional changes as suggested by Susan Lesch.
Editorial change. Updated section 3.1. Extended Backus-Naur Form (EBNF) Grammar to add
a new table showing how the N-Triples productions encode the respective
RDF concepts from [RDF-CONCEPTS].
Editorial change. Updated section 3.3 URI References
to say less about URI detail and defer to [RDF-CONCEPTS]. Removed reference to RFC2396 (URIs). Made after
comment by Duerst, 2003-05-08
as outlined. Also addresses
comment by Patel-Schneider, 2003-05-30.
Editorial change. Updated section 3.2 Strings
and the N-Triples escape sequence table to list the encodings
from Unicode character to N-Triples. Made after
comment by Patel-Schneider, 2003-05-27
as outlined.
Substantive change. Updated datatypeString to use
string rather than langString
after removal of language tag from all typed literals as
approved in RDF Core telcon 2003-05-09.
Entailment test definitions changed to actually test proper
entailments, not pseudo-entailments.
Support for datatype-aware entailment tests in the manifest.
Pointer to RDF-CONCEPTS for the definition of graph isomorphism
/ equality.
Addition of the always false pseudo-document for
entailment tests.
Updated the test case list in this document.
Test case names changed to fragment references into individual
manifest documents.
Production language. Changed to match
RFC 3066. Added [RFC 2396] to normative references.
3 N-Triples NOTE reworded. Point to
RDF/XML as exchange syntax.
Production character: should be "to
126"
3.2 Strings Removed suggestion to
use UTF-8 for apps.
Added 3.5. N-Triples Tests pointing
at the
http://www.w3.org/2000/10/rdf-tests/rdfcore/ntriples/test.nt
test file.
Use uppercase hexadecimal digits. Define H and use it for \uHHHH, \uHHHHHHHH.
Removed xmlString.
Changed the N-Triples language separator token to @ in langString
Added RDF datatyping support using datatypeString using the form
^^<datatypeURI>
Updated 3.3 URI References to
allow Unicode characters in URIs
Merged Future Work into Open Issues
Test case list expanded and reorganized to reflect additional
approved test cases
New section 2 describing organization
of parser tests, the types of tests and examples of manifest format
that describes them.
Updated editors, added thanks to Art Barstow.
Changed literal to be langString |
xmlString (now gone)
N-Triples remains an ASCII format for now - closed issue on
UTF-8 encoding.
Update references to RDF Model Theory, Syntax WDs
Changed the Approved Test Cases table so
that it includes links to related files and the Working Group
decision.
Removed the Test Cases Not Approved
table and added a link to the repository's list of the not approved
test cases.
Added links to ZIP files of the repository's test cases.
Specify the Future Work and Contributors sections as Informative.
Renamed token bNode to nodeID.
Added RDF Model Theory reference.
Added URI Encoding section, pointing at Charmod rules and
updated absoluteURI grammar rule to use it.
Removed references to Python literals, reason for
\-escaping.
Added 4, 8 required digits for \u, \U string escapes.
Renamed section URIs to URI References.
