Previous minutes

The minutes of the last meeting were adopted (as on the wiki).

Validation tools

Angelo Quaglia (JRC) presented a proposal for new analysis and visualisation tools to support testing as part of the geoportal. Previously, when one element was missing then the whole record would be reported as non-conformant but the JRC wanted to give stakeholders an indication on how close they are to being complete.

The proposed tools (that were shown in a presentation) included a short banner and a meter that would show the percentage of conformity from the Discovery service. Traffic light colours are used to help readily indicate how close content is to the ideal. It was noted that some metadata elements are more important than others- e.g. conformity is a lower rank. As well as overall measures, tables have colour coding on their heading to show how complete each section is, helping to quickly identify where there may be a particular element which is lowering the overall score.

The JRC welcome feedback on this proposal.

In general, Markus (AT) felt that a more relaxed validation approach can help so that differences of syntax do not cause an element to be valid. Emilio López (ES) and Tomislav Ciceli (HR) supported the proposal. Carlo (IT) suggested that the work should contribute to MIWP-5 activities and Paul (EEA) suggested gathering feedback from them.

Daniela (DE) asked who would be setting the importance of different elements and if the methodology was documented and available. Hannes (ESTAT) suggested reducing the text for the banner "average degree of conformity/conformance ".

DCAT AP and Metadata

Andrea (JRC) introduced work on the DCAT AP and INSPIRE metadata that is now summarised in the MIG wiki for feedback, with wider promotion of the work already taking place through ARE3NA and with the DCAT AP Working Group. Following some comments, a revised draft will be published on the wiki, including new sections on a subset of INSPIRE elements and another on full alignment. Andrea noted that where DCAT misses some element, other vocabularies would be used.

The JRC would like to know of any use cases of this to understand its utility and validity and to have examples and solutions related to this shared with the MIG and others.

Andrea also presented work on INSPIRE metadata elements and an analysis of the current content of responsible party roles. There is an interest in seeing how INSPIRE metadata can be used. Work has compared this to DCAT and it appears that some common roles occur. Potentially, at least one common specific role could be recommended (such as point of contact). This would aid discovery and support filtering of data. Details of this work will be shared on the wiki in a report for comment.

Annex I XML schema updates

Michael (JRC) provided details about the proposed updates to the Annex I xml schemas, which are documented on the MIG wiki. JRC are currently setting up a separate schema repository where shortly the proposed updated schemas will be published. This will support testing, to check if any Annex I related developments or software using Annex I schemas will break because of the proposed updates.

This work has uncovered new issues, which have been highlighted as discussion points that are contained in the sub-project's forum. JRC would like the MIG and others to provide input on these discussion points when people look at the changes. Feedback is sought especially from those who have worked with Annex I data in the past.

An ad hoc meeting took place at INSPIRE conference and work started at the JRC. Ewa asked how experts could join the work on MIWP-11, 12 and 18. Michael replied that a MIG sub-group still needs to be established to deal with these discussion and other issues of GML encoding. The JRC will draft a workplan and ToR (to be discussed with the MIG), and to launch an open call for participants.

Feedback will be sought until 15 September, with revisions published shortly after (end of September).

Markus (DE) raised an issue about how the MIG could better communicate this activity to implementers.

ARE3NA deliverables

ARE3NA has launched a series of review activities with the MIG (and other experts) of its recently completed and ongoing work. This includes:
  • Registries: A review of the candidate release of the INSPIRE Registry and Re3gistry (v0.4) software. A new sub-project in collaboration space for development and testing, including instructions and documentation, additional features for next releases and a roadmap (under construction). The MIG are asked to promote this testing widely with colleagues and other experts in their countries.
  • RDF and PIDs: The MIG are requested to review and provide feedback about the reports from the work completed in May on RDF vocabularies for INSPIRE and the governance of PIDs. The JRC would also like to know if there are people interested in trying to use the RDF methodology to create their own vocabularies and share examples. This includes a number of research projects and the MIG is encouraged to share these reports with them, too. It was suggested that it would be interesting to see what projects and experts could produce using this methodology. The PID guidelines should also be reviewed for comment. Following these reviews, both documents would be published as final reports.
  • Access control: The Access control/AAA study has produced a report documenting current technologies and standards that are used to access geospatial data and services. The overall work was presented at the INSPIRE conference but the MIG are asked to review these reports and provide feedback.

ToR for the proposed sub-groups

It was agreed that a common template should be provided for the ToRs for the sub-groups. This is an outstanding action on JRC.

Carlo (IT) said a draft ToR is prepared for the MIWP-5 sub-group, and that it should be ready to publish in the MIG wiki next week, with comments sought before the next meeting (end of August) to allow the proposed ToR to be adopted in the next virtual meeting.

Paul (EEA) said a draft ToR for the vocabularies work was also being prepared. Feedback will also be needed from the MIG.


JRC would like to organise a 2-3 day technical workshop in the second half of October on validation involving 5-6 experts that have already had experience with implementing validators (DE, FR, ES, nordic countries). The workshop will involve reviewing the requirements for metadata and services (work on data testing would come later) to draft an agreed interpretation of how these can be tested. The output of the workshop would, then, be shared with MIG and wider community.

Those attending the meeting were asked if they approved of the proposal or if there would be any other approaches that could help move this work forward.

Carlo (IT) and Daniela (DE) said it should be aligned with the MIWP-5 workplan and the tasks of the MIWP-5 to collect examples of validator software solutions should take place before organising the workshop. JRC suggested that the work could be independent as it would focus on the rules for testing rather than the technology but agreed that the MIG should quickly identify potential experts from their countries that could participate in the workshop (following the approach in previous meetings to ask for submissions of potential participants).

The JRC should share the workshop proposal with MIWP-5 leaders (or the whole MIG) next week.

Facilitators for Thematic Clusters

Some limited funding is available to support a meeting to bring together facilitators. A call will be launched in early August for facilitators, for selection by the end of September and the meeting shortly thereafter. The meeting will involve a discussion of their plans on how to facilitate their clusters and to look at the ways a discussion fora will operate, based on a refocused version of the INSPIRE Forum in order to support discussion of the thematic issues that arise.

Facilitators will be chosen based on their experience in liaison/facilitation of international communities, as experts in their field and, ideally, as someone who has been involved in developing the relevant INSPIRE data specifications for a cluster’s themes. In several cases, it will also be important for a possible facilitator to have a letter from their organisation to support their active participation (especially for those in public administrations). Further details will be made available in the call.

Download and Web Coverage Services

A similar approach to the SOS work is being discussed with Alex Kotsev (JRC), where a rough mapping of the download services requirements will be made to the WCS standard to see how the TG could be updated. A small contract would then be launched to implement these requirements in an open source solution and have an update to the TG drafted for submission to the MIG for review and endorsement (as planned for the SOS).

The JRC is interested in any projects or other activities that could help move this task forward, as well as the MIG helping to identify open source solutions and possible contractors that could bid for this work.

Next face-to-face meeting

The MIG-T meeting will take place in London on the 30 Sept/1 Oct. Official invitations and logistics details will be sent soon. The MIG-P meeting will be in Brussels on 15 September.

It is important for MIG members to fill in the Doodle poll to indicate who will participate in the meeting and who needs reimbursement, helping MIG-related budgets to be used more effectively.

MIG members are also requested to use the Redmine issue #2167 to propose topics for the meeting so that results can be readily shared.
