Although the initial literature review highlighted some common objectives across proposals and implementations, I struggled to find anything that defined "semantic routing" and goals that we could use/reference. I likely missed prior research that provides a useful definition. If not, then I agree that having the IRTF research community document a description for "semantic routing" and common goals, would be beneficial.

I take it you are referring to an approach being used in one of the largest IPv6 deployments: https://meetings.ripe.net/see3/files/Ian_Farrer-The_Terastream_Native_IPv6_Network_Architecture.pdf - Slides 15-17. If so, then I’d suggest this has already headed well beyond research into operational deployment!
