The invitation, including the Zoom link, is here.


  • Goal today: best practices for working together, not actually solving the problems
  • Communication channels and rationale
  • Who reads from the wiki?
  • hence: need for an ontology
    • How do we structure Internet of Things (IoT) devices like Tesla Cars or Amazon Echo / Alexa?
    • Should we make on item by model? Group of model?
    • One item by services? But what is the services? Typically Amazon Echo devices are linked to Alexa services, but they may differ in data collection.
    • Can we do a type of data collection and inject it in all Tesla Cars Model?
    • How do we index data controllers? Etc?
    • Project:Ontology
  • Overview of the wiki base technology. [video timecode 39:41]
  • Help:Templates
    • Including importantly how to enable a new one
    • Template syntax (maybe that might need to be a separate call)
  • Help:SPARQL
    • Querying .. whatever the equivalent of SQL is
    • How to generate visual query results (nodes, tables etc)
  • Merging?
  • Update queries/batch operations Help:Quick Statements
  • Other cool/useful stuff you can do that I might not be aware of (edited).>
USEFUL TOOL: Descriptions: Show the description of items and properties when hovering them.

Final video

Key timepoints:

  • [15:00] Explanation of how the GDPR request generator template is loaded:
  • [25:25] Explanation of User's own common.js
  • [28:28] Explanation of Gadgets MediaWiki:Gadgets-definition
  • [39:41] Explanation of Wikibase Technology: SQL datastore of triples. There is a CRUD API that interfaces with that. But it also uses a graph database to enable SPARQL queries. The SQL database gets fed into BlazeGraph using the 'updater' but this has a delay (a second to several hours). So query results may not be as up to date as what is in the database.
    • [42:05] how to access SPARQL query service
    • Help:Wikibase_technology
    • [43:00] API [[API help page]]
      • [43:12] API Sandbox
      • The moment you make an HTTP Post request via the API, that goes into the wiki's SQL database.
      • [43:40] Explanation of what a "claim" is.
