Why this property?[edit]

My intention when requesting this property is to make the **process faster** when trying to find an Open Data portal for data about an object e.g

What properties should an open data portal (Q27031827) have ?[edit]

We will learn and hopefully create a ShEx saying what properties we expect or recommends ...

My vision is that we get all providers of Open Data awar of Wikidata and the power of a Knowledge Graph -->

  • they start to describe what metadata they have using "same as" Wikidata objects
  • they start to describe in the data saying this school is "same as" a Wikidata objects and its located in "same as" Wikidata object

Doing that I guess is the only way to scale

What is the difference between this property and external data available at (P1325)[edit]

I don't understand why there is a need for a new property when external data available at (P1325) was doing the same stuff. I've been doing lots of work on French public agencies and I've always used P1325. See French Environment and Energy Management Agency (Q2826599) for an example. - - PAC2 (talk) 04:22, 7 July 2020 (UTC)[reply]

@PAC2: I didnt know about external data available at (P1325) when we requested open data portal (P8402) but I have seen the work you have done afterwards... should we merge? If yes what name is the best? "Open Data" is a buzzword used a lot - Salgo60 (talk) 11:10, 7 July 2020 (UTC)[reply]
I asked in the Telegram group Wikidata this question and got aware of that we have a big difference that external data available at (P1325) is an external url and open data portal (P8402) is to another object... so I think we need both and I also guess open data portal (P8402) is the preferred way to describe external open data in a better way... See how we describe our own Wikidata Graph - Salgo60 (talk) 11:38, 7 July 2020 (UTC)[reply]
Thanks @Salgo60:. Both are useful --PAC2 (talk) 21:29, 9 July 2020 (UTC)[reply]

Official and non official[edit]

A pattern I have seen is that we add if an Open data portal is official i.e. supported by the local government or done by a third party... any suggestions how we do that in the best way? cc: @So9q, Ainali, Abbe98: - Salgo60 (talk) 07:25, 4 August 2021 (UTC)[reply]
