I fully agree with you that the XSD model cannot by precisely integrated
into Wikidata and also I know Wikidata development is in progress. I
think I could deal with simple properties like "material" but I'm not
sure how to deal with complex properties like "construction phases" I'm
not sure. Even if it is no implementation yet, how these complex
properties could be defined?

You can't integrate the XSD model precisely as it is defined because
Wikidata doesn't allow all of the constraints that XSD allows.
Specifically, you'll notice that you can't force an item to have a
specific property (like the document or epigraphic reference in your
model) and enumerations aren't currently supported. Wikidata has a
global collection of properties and any item can use any arbitrary
subset of them. The list is here:
http://www.wikidata.org/wiki/Wikidata:List_of_properties. Some of the
ones you want already exist, like material used for a building.
http://www.wikidata.org/wiki/Property:P186 You'll want to propose the
other ones you want here:
http://www.wikidata.org/wiki/Wikidata:Property_proposal. I just added
two statements (when you use a property, called a claim without
references) to the Potaissa item that you use as an example.
