Hi Sabine, I also agree that we need to get in touch with PANRG. And really thanks for your effort in introducing ALTO to PANRG and introducing PANRG to our WG!
I just talk about some of my thinking. "how do endpoints discover trustworthy path properties?" can also be a basic question for ALTO. In my opinion, this question should cover three pieces: - Representation (which is like "How to connect" in your lightning talk slides) - Storage (which includes "When to connect" in your slides. Currently, alto-calendar is about it) - Requirements (rsa, fcs and incr-update-sse are related to it) I think a lot of previous efforts of ALTO WG focused on the first topic. But for the goal of PANRG and the future potential use cases, I think providing the on-demand network information will be more helpful. So maybe "how to define application requirements" is more important. The legacy ALTO approach can only support the simple cross-product filter requirement. To satisfy more requirements, we still need to make more efforts. btw. Shall we involve some people from PANRG into our coming interim meeting?
