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 that retrieve product info from wikidata searching by EAN number  (using wikidata query service 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
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

Agreed. However I don't think we need to see it black and white. There
are many things we can do and meet in the middle. Right now for
example Lucas and Olga are working hard on showing constraint
violations right next to statements and making them available via the
API. Additionally a team of students started working on exploratory
work for signed statements
(https://phabricator.wikimedia.org/T138708). Those are all pieces of
the puzzle that will get us to better data quality while still staying
an open project. I am sure we can do more in this direction. I should
take the time to write down more of my current thinking...


Cheers
Lydia
