Description

Issue: 

In the amendment of the Implementing Rules and the corresponding updated versions of the data specification Technical Guidelines, a number of changes have been introduced to the Annex I data models (for details, see Annex II of Commission Regulation (EU) No 1253/2013 and the updated data specifications), namely:

  1. Some candidate types and placeholders and the references to them have been removed (since they have been replaced by other types in the Annex II+III themes).
  2. Some candidate types and placeholders have been re-included in the Physical Waters package in the Hydrography theme
  3. Some references have been updated to types in Annex II+III themes
  4. Some additional sub-types of HydroObject have been created in the Sea Regions theme
  5. An additional data model has been developed for Maritime Units.
  6. One minor change of a geometry type (from GM_Surface to GM_MultiSurface) has been made in the candidate type Shore.

As a consequence, some of the Annex I xml schemas need to be updated to reflect these changes. If possible, any data sets that have already been created according to the current schemas (v3.0) should also be valid according to the updated schemas (or could be made valid by only changing a namespace).  

Furthermore, there is also a need to discuss, whether, when and how the updated encoding rules (that have been used for the Annex II+III schemas) are applied to the Annex I schemas.

Proposed change or action:

  • Propose updates to XML schemas for Annex I to make them consistent with the amended IRs
  • Propose a roadmap for applying the new encoding rules to the Annex I schemas

Organisational set-up:

  • Discuss issues in a workshop
  • JRC to propose updates to Annex I schemas and publish them after consultation

Outcomes:

  • Updated XML schemas for Annex I

Possible funding:

  • JRC institutional / competitive budget
  • MS funding

#7 Updated by Michael Lutz almost 4 years ago

  • Progress since the last meeting: Based on feedback from MIG-T on roadmap/deadlines for schema compliance, the following time periods were agreeed:
    • There should not be specific deadlines for minor versions, i.e. the deprecated minor version can still be used as long as the corresponding major version may be used.
    • Deprecated versions should no longer be used after 2 years after a major release
    • Deprecated versions should no longer be used after 1 year after a bugfix release 
  • Tasks/deliverables planned for the next month(s):
    • Documentation of the process and the changes made
    • Update the page on xml schemas on the INSPIRE web site with the agreed deadline, including the comments made by some of the respondents.
