I don't understand what exactly you're looking to do. Are you looking to install your crapthings/stardog-archetypes so that it's accessable to Stardog or are there constraints that you're looking to add to your uneskos archetype?
If you already have constraints you can add them to a constraints directory located in your archetype directory uneskos/constraints.
You can write your constraints in ICV, SPARQL or SHACL. The Stardog docs are the best resource for ICV or SPARQL constraints. There isn't a lot of good material for SHACL but a Google search or the specs would be a good start.
