[alto] Final Decision of Unified Properties Design before Moving to WGLC

[Jensen Zhang <[e-mail]>]

Hi all,

Authors of the document draft-ietf-alto-unified-props-new had a discussion
about the unified properties design last week. We reviewed two design
options proposed in IETF 104 and analyzed the pros and cons of both.

For the design option 1, binding resource dependencies to property type, it
is easy to process but hard to understand (we spend a lot of time trying to
clarify the design).
For the design option 2, binding resource dependencies to each entity and
property, it is easy to understand (analogous to the relational database)
but hard to specify (e.g., IANA registry). Fortunately, authors already
have a proposal about the IANA registry design of design option 2, which
requires three new registries for entity domain types, properties, and
resource types.

But we still need to make the final decision before we move forward.

Hi Sabine,

You mentioned that you still had some questions for the design option 2.
Could you post them here? I started to revise the document based on the
design option 2, but have not merged it to the latest revision. I hope our
co-authors can agree on a design at least before we moving to the document
revising for WGLC.

There are some materials talking about two design options:
