there is also Wikidata dump in HDT

I am new to it:
is it possible to store a weighted adjacency matrix as an HDT instead of an RDF?

Something like a list of entities for each entity, or even better a list of tuples for each entity.
So that a tuple could be generalised with propoerties.

Here an example with one property, 'weight', and an entity 'x1' is associated to a list of other entities, including itself.
x1 = [(w1, x1) ... (w1, xn)]
