Presentation Transcript

  1. Joint Research Centre • The Inspire Geoportal Validator

  2. Inspire GeoportalValidator - features • Validates metadata of INSPIRE resources with respect to the Technical Guidelines • Accepts ISO 19139 documents and endpoints of INSPIRE Network Services • Replaces the old schematron validator (now retired) • Available as a web page and as a RESTful web service

  3. Inspire Geoportal - Components

  4. Validator – Supported service specifications • Supported service specifications: • OGC CSW 2.0.2 – ISO AP 1.0.0 (*) • OGC WMS 1.3.0 - ISO 19128 (*), OGC WMS 1.1.1 (*) • OGC WMTS 1.0.0 (*) • OGC WFS 2.0 - ISO 19142 (*) • Atom based INSPIRE Download Services (*) • (*) With INSPIRE Extensions

  5. INSPIRE Geoportal Validator - Workflow

  6. INSPIRE Geoportal Validator - Implementation • Implemented in Java and based mostly on XSLT 2.0 for the initial transformation from the resource encoding • XSLT stylesheets are designed graphically using AltovaMapForce • Requires the commercial version the Saxon XSLT and XQuery Processor libraries (Enterprise Edition )

  7. INSPIRE Geoportal Resource Browser • The Resource Browser is a diagnostic tool for Member States and providers, for quickly identifying resources with issues

  8. INSPIRE Geoportal Resource Browser • Various criteria available for resource selection:

  9. INSPIRE Geoportal Resource Browser • Easy selection of all resources affected by the same issue type:

  10. INSPIRE Geoportal Resource Browser • Immediate identification • of resources portrayed • in an accessible • View Service layer

  11. INSPIRE Geoportal Resource Browser • Links to original ISO metadata is available for datasets, series and spatial data services:

  12. INSPIRE Geoportal Resource Browser • Technical note: • The Flash Player browser plugin is required for the image gallery to be displayed. • For the same reason, on Apple iPads, an App like Photon Flash Player is needed for image gallery to display.

  13. INSPIRE Geoportal Validation Report • Three sections: • Source document validation issuesFor XML documents it is the validation against the relevant XML schemas • INSPIRE validation issuesInformation required by the INSPIRE Regulations and/or Technical Guidance documents cannot found in the locations specified in • INSPIRE validation warningsWhen non- (or not yet) mandatory information is missing

  14. INSPIRE Geoportal Validation Report • Source document validation issues If a document does not respect the structure foreseen by its schema, subsequent validation steps might give unreliable results since the extraction information is based on XPath.

  15. INSPIRE Geoportal Validation Report • Example of schema validation errors:

  16. INSPIRE Geoportal Validation Report • Example of INSPIRE validation errors:

  17. INSPIRE Geoportal Validation Report • Documentation links next to each message take the user to documentation pages specific to each error. • Each error is linked to the corresponding requirement in the Technical Guidance (TG) documents. • Each TG requirement is mapped to the relevant INSPIRE Regulation requirement it derives from.

  18. Validation Processes

  19. Metadata Compliance Meter (1/4) • Validation reports now feature a metadata compliance meter. • This indicator shows how complete a metadata document, or group of documents, is with respect to the INSPIRE Metadata Implementing Rules, the Network Service Regulation and the Technical Guidance documents. • The indicators also include colour clues:

  20. Metadata Compliance Meter (2/4) • For example, if in a metadata document, one out of 10 required metadata elements is missing or is not compliant with the requirements, the indicator will show 90% or less, depending on the importance of the missing element.

  21. Metadata Compliance Meter (3/4) • The information will be available for each batch:

  22. Metadata Compliance Meter (4/4) • The information will be available also for the whole content:
