Hey,

I think the data model description is really clear (at least I think I have understood it ;) ). Maybe some points could be improved:

Concerning the Part about statements

I would maybe choose a top down approach to describing the individual components. i.e.:

A statement consists of a claim and optionally one or more references sourcing that claim. A claim consists of a property, a value and optionally one or more qualifiers

(and then go on about property, value and qualifiers as well as references)

To me such an approach seems to be more clear in reguard to the image showed on the right, than to start with the individual components and then go on about how they are grouped.

There seems to be a conflict with the requirement that "Wikidata will not be about the truth, but about statements and their references." however, since in the model references seem to be about claims and not statements (although being part of statements). Maybe a more concise wording could be choosen to harmonize the vocabulary.

Also maybe some visualization of the components can help understanding (example attached.)

Another thing: the "example statements" seem to actually be (pseudo) items with statements (?), but while the label is there the description is missing. Since the text above says every item must have a label and a description this is a bit confusing. Maybe a simple description can be added to the pseudo items.

Aw gosh, I really thought it is written with an "s". I guess I forgot the spelling, since Elizabeth II wasn't mentioned in the news for a while and so I wasn't reminded about how to write that name...

Thanks for reading, Cheers, Denny

Was the Elisabeth redirect some deliberate statement about internationalisation ;)

(Sorry internationalization!)

Heya folks :)

We've published a version of the data model that is less technical and that should be easier to understand than the very detailed existing one. You can find it at http://meta.wikimedia.org/wiki/Wikidata/Notes/Data_model_primer Feedback welcome!

Cheers Lydia
