* Goal today: best practices for working together, not actually solving the problems
* How do we structure Internet of Things (IoT) devices like Tesla Cars or Amazon Echo / Alexa?
* Communication channels and rationale
** Communication on the wiki:
*** use <code><nowiki>{{reply_to|Podehaye}}</nowiki></code> to ping someone (alert when they log in, [https://wiki.personaldata.io/wiki/Special:Preferences#mw-prefsection-echo email if configured to receive emails])
*** use <code><nowiki>~~~~</nowiki></code> to sign, see https://en.wikipedia.org/wiki/Wikipedia:Signatures
* Who reads from the wiki?
** once in a while:
*** [https://labs.letemps.ch/interactive/2020/demander-ses-donnees/ Le Temps] for their [https://www.letemps.ch/societe/reprenez-controle-vos-donnees-temps-propose-une-experience-participative investigation]
** continuously:
*** popup, introduced by [[MediaWiki:Common.js]] [video timecode 15:00]
*** opt-in/opt-out gadgets, introduced via [[MediaWiki:Gadgets-definition]] [video timecode 28:28]
*** eventually augmented by user script (e.g. [[User:Podehaye/common.js]]) [video timecode 25:25]
* hence: need for an ontology

** 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.

== Key timepoints and notes ==
* [15:00] Explanation of how the GDPR request generator template is loaded:
** [15:00] [[MediaWiki:Common.js]] (Javascript)
*** [15:44] [[MediaWiki:Access.js]] (Javascript)
**** [16:28] [[Template:Menu]] (wikibase template language)
***** [16:54] [[Template:MailtoAccess]] (wikibase template language)
****** [17:42] [[Template:mailto]] (wikibase template language)
****** (not shown) [[Template:wikidata]] (wikibase template language)
****** [19:20] [[Template:Access]] (wikibase template language)
******* [20:53] [[Module:wd]] (Lua) - documented [[https://en.wikipedia.org/wiki/Module:Wd here]]
* [25:25] Explanation of User's own common.js
* [28:28] Explanation of Gadgets [[MediaWiki:Gadgets-definition]]
** [28:32] QuickPresets Gadget - demo. Code is at [[MediaWiki:Gadget-QuickPresets.js]]
** [28:58] How to turn Gadgets on and off
* [39:41] Explanation of Wikibase Technology: SQL datastore of RDF 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 [[[https://wiki.personaldata.io/w/api.php 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. - it is effectively an RDF triple. e.g. Item - Property - Item or Item - Property - String/datatype
*** Wikibase has a separate layer, its interpretation of the underlying RDF triples.
* [46:29] Namespaces
** [48:55] Can you move pages between Namespaces? Yes. (show how)
** [49:25] Do users have their own sandbox namespace? Yes everything under your username is a namespace e.g. you can just make [[User:Alexbfree/ExampleSandboxPage]]. (This could be useful for testing things privately before they are shared with other users)
** [50:46] The Easy Query Gadget [[MediaWiki:Gadget-EasyQuery.js]] which shows all items that have this property. Activated by default for everyone. Just click the [...] next to a title.
*** [51:25] Using the Easy Query Gadget to see a quick node graph for an Item, and then access the SPARQL for that query.
** [52:14] Show Derived Statements gadget [[MediaWiki:Gadget-relateditems.js]] - see which pages link to/use this one.
* [53:39] SPARQL demonstrations
** still need to add timecodes/notes here...
