Assessing & improving client support for INSPIRE data

The INSPIRE Directive aims to establish an EU interoperable Spatial Data Infrastructure. With the approaching of implementation deadlines, an increasing number of datasets are made available on the INSPIRE Geoportal in the GML format. Within the INSPIRE Maintenance and Implementation Work Programme (MIWP), an Action was started to evaluate and improve client support for INSPIRE datasets. Many desktop and web, proprietary and open source clients (QGIS 2.18 & 3.4, Esri ArcMap 10.5, Esri ArcGIS Online, OpenLayers 3, Leaflet 1.4, OGR, FME and Hale Studio) were tested in: loading/creating/editing data, handling big files, managing geometry (e.g. mixed type geometry), handling CRS, loading/displaying 3D coordinates, managing special properties (e.g. complex data types or attributes with multiplicity > 1). Tests were run on datasets in both GML and GeoJSON formats, the latter being currently studied as alternative INSPIRE encoding. First results show that desktop clients outperform web clients, with QGIS performing the best. A meeting with software vendors to share results and improve client support will be the next step.

INSPIRE Reference Validator: status and next steps

The INSPIRE Reference Validator is the tool adopted by EU Member States to validate the resources of their Spatial Data Infrastructures. It is an implementation of the ETF, an open source testing framework based on ISO and OGC standards, which performs tests organized into Executable Test Suites (ETS) using SoapUI, BaseX and TEAM Engine. The ETF can be used via either a web application or a REST API; a Docker container is also available for quick deployment. The INSPIRE Reference Validator, recently deployed on the cloud, offers many open source ETS to test data sets, metadata, View Services (WMS, WMTS), Download Services (Atom, WFS, WCS, SOS) and Discovery Services (CSW) against the interoperability requirements set by the INSPIRE Technical Guidance documents. Starting from the context of INSPIRE Action 2017.4 on Validation and conformity testing, the talk will present the latest developments of the ETS and ETF (including the governance of the software project) and describe the future plans.
