Orléans/OGC INSPIRE Hackathon 2018: Standardised Metadata


The upcoming OGC TC/PC Meetings in Orléans, France (19-22 March 2018), will host the final presentations and awards ceremony of the next installment of the INSPIRE series of hackathons: the Orléans/OGC INSPIRE Hackathon 2018.


INSPIRE hackathons are organised annually to coincide with the INSPIRE conference, which will be held in Antwerp, Belgium this September. Throughout the year, however, so called ‘satellite’ INSPIRE hackathons focus on different topics. The results from all these satellite hackathons are collated and presented at the annual INSPIRE conference.


The Orléans/OGC INSPIRE Hackathon 2018 is one such satellite hackathon, and will focus on geospatial metadata standards. The hackathon is organised by the Plan4all association in close cooperation with OGC and several EU projects including DataBio, NextGEOSS, PoliVisu, and EUXDAT.


The key topic of this satellite hackathon is metadata, its standardisation, and innovative approaches to its management and presentation. Improving the discoverability of geodata and information is vital for increasing their use and re-use across the broad geospatial community.


So, even though few people enjoy spending time on the collection and maintenance of metadata, there is a universal agreement across communities that we need good quality metadata. We therefore need to improve the ways that we create, manage, and use it. It’s not like standards don’t exist to support this work, though: the geospatial community has its ISO 19100 series of standards which formed the basis for the INSPIRE metadata implementing rules and guidelines.


However, in the world of general ICT and other sectors, Data Catalog Vocabulary (DCAT) is the reference. With this is mind, the EC-JRC, within the framework of the ISA programme activities, developed the GeoDCAT-AP profile to make exchange and integration of metadata from geospatial resources and other resources possible.


Several members of the OGC, with the help of OGC staff, have set-up a DCAT Geospatial subgroup of the Metadata Domain Working Group (DWG) to collect examples of Best Practice implementations of GeoDCAT-AP. These examples, and the challenges for an integrated management of metadata resources, are currently bundled in an OGC Best Practice document.


This satellite hackathon on metadata will start from these experiences, but wants to put some new challenges and possible work topics in the picture. Possible topics could be (but are not limited to):

  • New ways of visualising GeoDCAT-AP resources;
  • User friendly integration of metadata from different catalogues;
  • The use of Schema.org for improved data discoverability;
  • Supporting the connexion between Geo- and Earth Observation portals;
  • Linked Data approaches to metadata;
  • Sensor based concepts like sensor semantics network (SSN) ontology.


The Hackathon officially started late February, with the creation of teams for the event and a webinar outlining the direction of the hackathon (available online here). The teams will work on their projects until 20th March, and will then present the results at a side event of the Orléans TC/PC Meeting the following morning, with the award ceremony before lunch.


While the Hackathon has already begun, it’s certainly not too late to start! If you’d like to sign up or join an existing team, visit https://goo.gl/forms/0KYqycoYj0UZVabz1. Another informational webinar outlining the Hackathon, and covering the topics of unifying data and metadata, linked data in agriculture, and metadata in Open Land Use, will be held on March 14 at 11am CET. Registration is available here.

You can create your own team with people you know or people you’ve worked with before, or you can can explore the existing ideas and teams that have been already created and join them. In any case, you need to register in order to gain access to the shared space where the building of teams and designing of ideas is happening.

A judging panel will decide their three favourite projects taking into account the following selection criteria:

  • Connection with INSPIRE, Copernicus, GEOSS and other initiatives
  • Connection with OGC works,
  • Innovation.

All the teams will be invited to present their projects during the dedicated workshop at the OGC meeting in Orléans, France. For this reason, teams will be asked to prepare a presentation showing their hackathon results. This presentation will have to emphasize the use or link with OGC works, to help the audience understand easily the connection with their area of interest. The presentations will be broadcast on social media, and the winning teams will be interviewed (video/audio). Teams responsible for exceptional projects will be invited to co-author scientific papers documenting their projects,with additional prizes to be announced soon.

The Orléans/OGC INSPIRE Hackathon 2018 is organised as part of the 106th OGC Technical Committee meeting in Orléans (France) on 22nd March 2018. Information on the venue is available here: www.ogcmeet.org

Sign up for the hackathon is still open, and available at: https://goo.gl/forms/0KYqycoYj0UZVabz1
