Abstract
The document describes and presents test cases for the Protocol for
Web Description Resources (POWDER). The test cases aim to indicate the
correct formats of POWDER documents and illustrate various crucial
aspects on the usage of POWDER documents, such as locating a document
and infering information from it.

1 Introduction
As part of the POWDER specification, the POWDER Working Group
provides a set of test cases. The present document discusses these test
cases. They are intented to facilitate and exemplify the creation of
POWDER documents of varying complexity and provide a means to assert
the conformance of software applications designed to handle POWDER
documents.
The document provides a description of the various test types, the
format that was used and the structure of the manifest files that
accompany the tests.
2 Test Types
The tests are classified with respect to the issue they aim to
examine. The main concerns are the syntactic validity of a document,
the equivalence between various forms of POWDER documents, the ability
to locate a POWDER document
associated with a resource and the ability to infer information about a given resource from a POWDER document
associated with it. The following sections indicate the classification
of the tests included in the test suite and describe their structure.
2.1 Parser Tests
The parser tests aim to provide a test corpus for implementations of a POWDER parser.
The parser tests are initially separated into positive and negative
parser tests. Each test examines the valitidy of a POWDER document
against a conformance requirement of the specification. The documents
included in the positive tests meet the requirement they are tested
against, whereas those included in the negative tests violate a given
element of the conformance model.
When given a positive parser test document as its input, a POWDER
parser is expected to return a validity confirmation message. In
contrast, when the input is a negative parser test document, the POWDER
parser is expected to report that the POWDER document is invalid, and
may return a message indicating the requirement that is not met, as
indicated in the manifest file accompanying the POWDER document of the
test.
Each test consists of one POWDER document
and a Manifest file. The POWDER document is named posNNN.xml or
negNNN.xml if it is included in the positive or negative parser tests
respectively, where NNN is the index number of the test with three
digits. The Manifest file is named ManifestposNNN.rdf or
ManifestnegNNN.rdf.
2.2 GRDDL Tests
The GRDDL tests aim to provide a test corpus for implementations of a POWDER-to-POWDER-S transformation tool.
These tests include pairs of documents. The first peer is a POWDER document,
named powderNNN.xml and the second is a POWDER-S document, named
powdersNNN.rdf. Each POWDER-S document is what should be derived from
its corresponding POWDER document when applying a transformation on the
latter. The transformation may or may not be performed using the XSLT
provided for this purpose, but the output POWDER-S document must be
semantically equivalent (i.e. correspond to equivalent graphs). The
Manifest file describing each test is named ManifestgrddlNNN.rdf.
2.3 POWDER Locator Tests
The POWDER locator tests aim to facilitate the testing of
applications used to examine the association of a resource with a
POWDER description that applies to it. The tests comprise pairs of
documents. The first document defines a web resource that contains a
reference to a POWDER document
while the second one is the POWDER document itself. Any locator MUST
reach the POWDER document via the resource, or report. There are tests
for each means of locating a POWDER document, as defined in the DR
document included in the specification [DR].
The purpose of these tests is to provide an adequate data set for testing a
POWDER Processor
by providing the expected return values of a describe(u) function with
a given u and against a given POWDER document. The tests comprise of a
fixed IRI, a POWDER document
and an RDF graph expressed in RDF/XML that shows the results of running
describe(u) - where u is the IRI provided by the test - against the
POWDER document
3 Manifest Files
The Manifest files provide a formal, machine-readable description of
the test they apply to. Those associated with the POWDER tests follow
the schema developed for the RDF test cases [RDF-TEST].
Furthermore, the said schema is extended to include some new properties
and types, as defined in the POWDER test ontology.
Each test is associated with a Manifest file, identified from the
URI formed from the file's URL with a fragment test. A given test has a
rdf:type explicit, within the scope of:
wdrtest:parsertestwdrtest:grddltestwdrtest:locatortestwdrtest:dataextractiontest
Where the wdrtest namespace is bound to http://www.w3.org/2008/07/powder-test/testSchema# and rtest
is bound to http://www.w3.org/2000/10/rdf-tests/rdfcore/testSchema#.
The name of the original author of each test is given using a dc:creator property.
The description of the test is given as a value of a rtest:description property.
The relevant requirement of the specification that this test examines is given as value of a wdrtest:specref property.
The input document for a test is given as a value of a
rtest:inputDocument property, whereas the expected output document, if
applied, is given as a value of a rtest:outputDocument property. If the
production of an output document is not the purpose of the test
process, the wdrtest:expectedDocument can be used to provide a free
description of the expected results from the execution of the test.
The status of a test included in the suite, declared using a rtest:status property, can be in the set of the following values:
- APPROVED
- REJECTED
- PROPOSED
4 The POWDER Tests
This section demonstrates the documents included in the POWDER Test
Suite. The documents are categorized with respect to their type. Each
test is defined by the following parameters:
- The type of the test.
- A description for the purpose of the test, with respect to its type.
- A link to the section of the relevant document that defines the part of the specification that is subject to the test.
- The index of the test in the particular type.
- A link to the Manifest file that provides a formal description for the test.
- The preconditions that must be taken into account in order to consider the test valid.
- The documents that are part of the test.
The actual documents, along with the Manifest file, can be downloaded in a compressed file. The directory structure of the compressed file has as follows:
- Top Level
- POWDER-TS: The entry directory
- Second Level
- positive parsers tests
- negative parsers tests
- grddl tests
- locator tests
- data extraction tests
Each directory contains the test documents of the corresponding
type, along with the manifest file of each test and following the
naming conventions discussed in the present document.

| GRDDL Test |
Positive |
Transformation of a POWDER-BASE document to POWDER-S. As with GRDDL test 006, the
input file is designed to contain many different POWDER features rather than present a realistic data file. |
007 |
| Test Assertion |
| POWDER features, such as ordered lists, pre-defined descriptor sets and DRs with multiple IRI sets
are transformed as described throughout the docmentation. This test data presents a particular
challenge with respect to the numbering/identification of different elements. |
