  • PROV spec/alt definitions: 
    • alternate: "Two alternate entities have equal or different aspects of the same thing" 
    • specialization: "An entity that is a specialization of another entity shares all aspects of the latter, and additionally provides more specific aspects of the same thing as the latter"
      • Tim: s/provides/have/ ??? or s/have/provides/ ???
      • Tim: "aspects of the same thing" provides a nice "out".
    • James Cheney seems to insist that spec and alt are always talking about the same thing. Since "same thing" is pretty fluid outside of mathematics (and we're not talking about mathematical identity), I'm beginning to think we can just let it be as it is above.
