4 ESDIN An econtentplus Best Practice Network project September 2008 to February 2011 Coordinated by EuroGeographics Key goal: help National Mapping and Cadastral Agencies (NMCAs) member states, candidate countries and EFTA States prepare their data for INSPIRE Annex I spatial data themes and improve access

5 ESDIN In total 7 ESDIN-related presentations at INSPIRE 2011 In particular: Thu 16:00, David Overton, ESDIN - the geospatial reference data and services for INSPIRE Fri 09:20, Antti Jakobsson, European Location Framework- How to provide geospatial reference data and services for Europe based on INSPIRE This talk focuses on the ESDIN test environment

6 ESDIN specifications Use INSPIRE service specifications Extend INSPIRE data specifications Additional information that already is part of current data products of EuroGeographics and which is used by existing customers has been added Information that may be void in the INSPIRE data specifications (i.e. is not necessarily provided in INSPIRE), but which can be provided by NMCAs is made mandatory Minimum data quality levels have been specified for European NMCA data

7 ESDIN testing Provide a systematic approach to testing the technical results of the ESDIN project and support implementation activities General testing approach: Automated testing Black box testing

8 OGC compliance testing (CITE) vs OGC CITE tests ESDIN test requirements Use a test data set Test a software product Not for all service and data standards available ESDIN Test requirements Test a service instance, not the capabilities of a software product Products used in ESDIN have to pass CITE tests where they are available Test against INSPIRE and ESDIN extensions

9 ESDIN data production and publication workflow Transformations Source to target model Other data Source data Coordinates Generalise Edgematching Publication data Download Authentication Translate View

10 Test targets overview Publication of spatial data in the SDI INSPIRE view services / OGC WMS INSPIRE download services / OGC WFS INSPIRE view/download services via SAML/Shibbolethbased authentication services INSPIRE coordinate transformation services INSPIRE and ExM data sets Data production processes Medium-to-small-scale generalisation Data quality evaluation Edge-matching processes

11 Test cases overview Test cases documented using a common template for all test targets In total 165 pages of test cases

16 Using soapui and loadui (loadui for load tests) Modified version of soapui to support additional capabilities for implementing test cases 2010 Open Geospatial Consortium 16

17 Experiences in ESDIN Very positive feedback from National Mapping and Cadastral Agencies within the project transforming the data and setting up the ESDIN web services Tests enable the discovery of problems by the developer at an early stage of the implementation Automated tests allow monitoring the operation, too Positive feedback from EU project review: ESDIN is one of the first projects that also provide appropriate testing tools that can check the conformity to the ESDIN data specifications as well as conformity to INSPIRE. These results should be forwarded to the INSPIRE community. one of the reasons we are here Additional work needed Improve reporting of reasons for failed tests Align with progress in INSPIRE specifications (new Technical Guidance documents for network services, new data specifications, etc.)

18 Additional information Test framework: Deliverables: D12.4 Test cases D12.5 Test components D12.6 Test results

19 Final remarks The ESDIN Test Framework is available under BSD license The ESDIN consortium is preparing the steps to maintain and improve the project results in the future and the test components will be part of this Currently the test framework has its home in a Subversion server at interactive instruments, but we plan to move this as part of this process We are looking for opportunities for further collaboration to improve the test framework and make it available for future use in INSPIRE and national/community SDIs
