To achieve interoperability in a spatial data infrastructure (SDI), conformance to specifications is essential for services and data. Service and data providers need a capability to validate their SDI components.
To address this, the European Location Framework (ELF) project has developed a strategy for validating the INSPIRE download and view services and the data encoding provided by National Mapping Authorities (testing data quality is an additional activity, but takes place during the preparation of the data set). The strategy builds on existing validators and new developments for INSPIRE- and ELF-specific tests:
* OGC CITE tests are used to validate conformity against the base OGC standards (WFS, WMS).
* The INSPIRE Geoportal Validator is used to validate the metadata, including the service metadata (Capabilities documents of WFS and WMS).
* The test framework ETF is used to validate INSPIRE services and data against the INSPIRE Technical Guidelines as well as against ELF-specific requirements.
* The Spatineo tools are used for performance testing and monitoring of the ELF Platform.
We present this approach in more detail and discuss the challenges that have been encountered in the ELF testing, in particular when testing download services (WFS) and interpreting errors reported in the test results.
The improvements to ETF and the INSPIRE- and ELF-specific tests that have been developed, partly as a response to the identified challenges, are discussed. ETF is open source and supports SoapUI (for testing web services) and BaseX (for testing XML documents, including very large ones) as test engines to develop and execute test suites. ETF has been implemented in several iterations over recent years as existing open source test environments could not be configured to provide uniform test reports that were sufficiently clean and useful for non-developers.
