RDF term equality definitions

[afs]

There are definitions for IRI equality and literal term equality.

There aren't definitions for "blank node equality", "triple term equality" or a general "RDF term equality".

Would it be useful to add these?

SPARQL needs definitions for term equality in sameTerm and other places.

SPARQL 1.1 has it's own definition, and while this could updated to referring to RDF Concepts for IRI and literals and otherwise keeping the current text, if RDF Concepts has "RDF term equality", SPARQL 1.2 ought to use that.

I am not sure about "blank node equality," but I will definitely go with "triple term equality."

"blank node equality" is "same object" i.e. identity in the set of all blank nodes

I think it's implicitly there, just there isn't a reference.

"the set of possible blank nodes is arbitrary." sets are defined by elements identity.

They are arguments to mappings in https://www.w3.org/TR/rdf12-semantics/
