Wikidata's rules work because they are the same for everything/everyone and apply in the same way to everything/everybody. If they think their data are so valuable that we cannot be trusted with their maintenance, they can very well keep it. L.

Hi, thanks for your replies, Luca, not offended at all, I'm not interest in preserve company interests nor abandon open aproach, quite the oppositte, maybe I didnt explain well before: When I say protect some data I refer something like protect "Berlin is the capital of Germany" in a wikidata statement. The equivalent in this case whoul be for example "the EAN (European Article Number) for Raspberry Pi Model B 512MB is 2100000010196". Protect this kind of information whould be neccesary for people to use it in a realiable way. Lets say somebody has a Online Store , or Inventory Management Software or a product review website <https://lib.reviews/> that retrieve product info from wikidata searching by EAN number (using wikidata query service <https://query.wikidata.org/> API) number, they need to know that product EAN number will be always the correct number for this product. Regarding company interests, using wikidata for storing product info (I called this wikiobjects but the name doesn't matter) people would be able to find "fridges with A++ Energy Label" or "Lowest carbon footprint laptops with less that 2 kg weight", again you need that weight and carbon/energy certificates trustworthy values. For companies will be interesting that their products are in wikidata, because if wikiobjects gets popular, it could be like other online platforms, "if it is not in , it doesn't exists" and this is important for companies although they expose their products to inevitable good and bad criticism. Lydia, agree with not black/white, Signed statements and inline validation, wow!, I didnt know about them, quite cool features, I have added them to wikiobjects project proposal page in a new section <https://meta.wikimedia.org/wiki/WikiObject#SWOT_Analysis:_strengths.2C.C2.A0weaknesses.2C.C2.A0opportunities.2C_and.C2.A0threats> I have seen that changes in references and qualifiers don't break signature nor trigged a warning like label and description changes, just curious why not. greetings 2017-05-10 16:18 GMT+02:00 Lydia Pintscher &lt;lydia.pintscher(a)wikimedia.de&gt;de>:
