Building arguments on Open Data

  1. 1. Building arguments onBuilding arguments on open dataopen data philippe duchesne phd@highlatitud.es @pduchesne OpenBelgium 2018 Louvain-la-Neuve March 12th, 2018 how annotated open datahow annotated open data fragments can rest your casefragments can rest your case
  2. 2. Open data annotations technologies IntroIntro at the service of engaged citizens
  3. 3. engaged citizen What? What?  Explore data portal/catalogs Chunk up data and reassemble into a meaningful argument Share that argument Have others derive work from your findings IntroIntro
  4. 4. Ultimately...Ultimately... goal is to model and share a thought process based on open data IntroIntro has to be  shareable -> open data verifiable -> assessment of authenticity of sources reproducible -> standards-based, open description of process
  5. 5. Preamble : Data standardsPreamble : Data standardsTechTech as the 3rd star of open data, it should be obvious by now... but considering the current state of open data, it's better to rub it in XLS sheets ZIP files a link to a webpage that gathers some data .... are not open data standards!
  6. 6. Verifiability & reproduceability --> capture data lineage TechTech Towards a Mosaic standard :Towards a Mosaic standard : Metadata standardsMetadata standards data provenance metadata origin authenticity based on Dublin Core vocabulary data processing modelling need for data process description vocabulary Considered ontologies: OntoDM, DMOP
