Create RDF::Query::Node->from_attean analog #128

Closed kjetilk closed 9 years ago

kjetilk commented 9 years ago

I don't know if this makes sense at all, but it fixed my immediate problem. :-)

It should probably be a coercion, or be done in some other way entirely.

kasei commented 9 years ago

Happy to merge this if you change from_attean to check does() on the Attean::API::* roles, instead of checking isa() on the concrete classes.

kjetilk commented 9 years ago

Sure!

BTW, does Nil exist in Attean?

kasei commented 9 years ago

No. Nil was needed to cover up a bad design decision in Trine: the need to represent the default graph. In Attean, models are full quad/graph stores without any notion of a default (unnamed) graph. It's the query planning process that converts the concept of a default graph into a query plan that references explicit graph names in the model.

OK, cool. I removed that, then. :-)
