It's correct that the TRAPI spec for Attribute no longer has "name" as a property. Instead:

• "attribute_type_id" is supposed to say what the attribute is (although Automat is just putting "biolink:Attribute" here which doesn't say what exactly is there...)
• "original_attribute_name" is supposed to be what the data / knowledge source actually calls this edge property / association property / piece of info.

It would still have to be discussed with Andrew / Chunlei, but I've been thinking that BTE should do something similar to Automat - rather than its current behavior of dealing with Attributes it gets from non-TRAPI APIs.
