Welcome and approval of the agenda

An additional discussion issue was added on the AOB agenda point on how to deal with procurements of external contracts to support the work of the MIG sub-groups. Otherwise, the agenda was aproved as proposed. 

Minutes of the previous meeting

There were no comments on the minutes of the previous virtual meeting and the face-to-face meeting at the INSPIRE Conference. They were adoped as currently proposed.

The open actions from the previous meetings were reviewed, and it was agreed to close actions #2250, #2165 (temporarily until the proposed action has been endorsed for the MIWP), #2236, #2374 and #2380.

Christina confirmed that #2456 is to be covered by the small group on SDS and asked someone form the Commission to join the group.

It was agreed that issue #2455 is best addressed in MIWP-8. It should then be decided in next MIG-T meeting whether to add this to work plan of MIWP-8.

On the actions related to the updated XML schemas, Michael reported that also a new version of the UML repository (with some minor corrections and the updated tagged values for the namespaces and versions) has been published at https://inspire-twg.jrc.ec.europa.eu/svn/inspire-model/branches/public/approved/latest/ and that JRC plans to cleanly separate the models included in the IRs from those included in the TGs in a future release (in August/September). He also clarified that there is currently no published version of the UML repository that 1:1 represents the v3.x data models. If this is needed by stakeholders, such a version could be created (as a branch) during the planned update.

Progress of active MIWP actions

The issue was raised that work in some sub-groups (notably MIWP-8 and MIWP-5) may have an impact and require changes in other documents. For MIWP-8, this is documented in #2408 and dependencies or impacts on other TGs will also be clearly indicated in the reading guidelines that are currently being produced.

Other sub-groups are encouraged to highlight such issues in a similar way and to report such issues in the regular status reports.

TG for Spatial Data Services

Daniela raised the question how to document that the approach for SDS metadata will be changed with the upcoming update of the MD TGs. This should be done rather soon since some countries are already preparing calls for tenders and need to be aware of what is the latest agreed version, even if the document is not yet updated.

It was agreed to publish a note on the INSPIRE web site pointing to the agreed new approach for SDS metadata. For this, the SDS section needs to be extracted from the TG Metadata draft [Action Michael Östling & JRC]. The SDS TGs can the be updated at a later stage, including also updates from the SDS discussion paper Christina and colleagues are currently preparing.


  • All participants were reminded to send to Robert Tomas the national contact points for the Thematic Clusters
  • Michael clarified that, if a sub-group needs support through external contractors, this should be identified in the sub-group's terms of reference. A budget is available from DG ENV (managed by JRC) to support such supporting contracts. The specific contracts will then be discussed between the sub-group (leader) and JRC.
  • The next face-to-face meeting will take place in Rome at the end of November/beginning of December, according to the following schedule:
    • Mon 30/11 noon - Tue 1/12 noon: TC facilitators
    • Tue 1/12 noon - Thu 3/12 evening: MIG-T (including 3/12 morning: eENVplus final conference)
    • Fri 4/12: MIG-P
