Additional resources



Overall, delegates are in favor of extending the TG for INSPIRE download services with SOS. Reasons which were discussed are that SOS is better suited particularly for observation data. The following issues were raised which need further attention from JRC and 52 North:
  • Offerings
    A discussion was raised on how exactly to group observations through the offering parameter for the SOS, in order to satisfy the requirement of INSPIRE for serving datasets. Reason are that there may be problems with the size of the GetCapabilities response, if there are many offerings in one SOS. Several options were proposed, such as:
    • One offering per parameter?
    • One offering per monitoring station?
    • In the case of air quality e-reporting - country/parameter/year
    • The question about units of data that should be described in the metadata for discovery is open

Conclusions and Way forward

The following was agreed by the group as follow-up:
  • Activities related to TG update
    • Next version of draft TG to cover comments from the meeting will be prepared by 12 May [Action 52N]
    • A MIG sub-group on SOS will be established in order to facilitate a broader consultation by mid May [Action JRC]
    • A wiki/issue tracker will be set up and maintained during the commenting period
    • Comments can be provided by end of July and resolution will be done by end of August [Action JRC/52N/MIG]
    • Final draft of the Technical Guidance document will be ready and disseminated by end of September [Action MIG]
  • Activities related to open source implementation
    • The war file of the 52N INSPIRE/SOS implementation will be provided to all participants by end of May [Action JRC]
    • Participants will deploy and load the solution with own data & then provide feedback by Mid July. The aim is to have organisations from different countries for each thematic domain [Action INSPIRE/SOS workshop participants]
    • Different clients applications will be tested for the INSPIRE/SOS
  • As a parallel activity, providers of other SOS implementations should be contacted and asked whether they would like to implement the INSPIRE extensions described in the draft TG in their products. This activity should allow verifying whether the guidance which is provided in the TG can be achieved with different SOS implementations.
