RML-FNML: Test Cases

Status of This Document

This specification was published by the Knowledge Graph Construction Community Group. It is not a W3C Standard nor is it on the W3C Standards Track. Please note that under the W3C Community Contributor License Agreement (CLA) there is a limited opt-out and other conditions apply. Learn more about W3C Community and Business Groups.

GitHub Issues are preferred for discussion of this specification.

The test cases are semantically described for re-usability and shareability following the W3C Test case description. Each test:Testcase as the following properties:

dcterms:identifier: unique ID of the test case.
rmltest:hasError: if an error of the RML Processor is expected or not.
rmltest:input: One or more input data of the test case.
rmltest:output: One or more output data of the test case.
rmltest:inputFormat: the input data format.
rmltest:outputFormat: the output data format.
rmltest:mappingDocument: the RML mapping rules in Turtle.

This section describes the RML-FNML test cases. These descriptions are also available as RDF. The files are available on GitHub in the folder test-cases. Each test case is contained in a single folder, containing three types of files:

Zero or more files containing the data sources, in the case of JSON, XML, CSV, or containing the SQL statements to create the necessary tables, in the case of MySQL, PostgreSQL, and SQL Server.
One file with the RML rules, called mapping.ttl, in the Turtle format.
Zero or more files with the expected RDF. No file is provided if an error is expected that must halt the generation of the RDF because of an error.

Title: Function on object, 0 parameters

Description: Tests (1) if a function without parameters can be used (FnO) (2) if a function on an object map can be used (Term) (3) if the output of the function is assigned the correct termType by default

Error expected? No
