openkvk.nl

Openkvk.nl site (set up as formatter URL) does not work. To be precise site itself is working, but database apparently not. Is there any alternative?--Jklamo (talk) 08:32, 17 April 2018 (UTC)

@Jklamo: The site seems to work if you search manually, but the formatted links from Wikidata don't work. I don't know of any alternative way to link it. I'll remove the formatter URL (P1630), since getting a message "410 gone Dit bedrijf is niet meer actief" is potentially confusing. Ghouston (talk) 10:25, 10 July 2018 (UTC)

It would be possible to make a link to https://www.kvk.nl/, although it seems you only get name and address for free. Ghouston (talk) 10:32, 10 July 2018 (UTC)

[1] or [2] or any better link?--Jklamo (talk) 10:43, 10 July 2018 (UTC)

Yes, just name and address, and ugly pages. Ghouston (talk) 10:58, 10 July 2018 (UTC)

Still, it verifies that the number is correct, so it's better than nothing. Ghouston (talk) 11:05, 10 July 2018 (UTC)

User:Sjoerddebruin restored the openkvk formatter: which is OK, since it's working again and gives more information than the kvk.nl site. Ghouston (talk) 03:22, 19 August 2018 (UTC)

It's not working at the moment and gives an error. I will temporary switch to https://www.kvk.nl/orderstraat/product-kiezen/?kvknummer=$ User:Hannolans
