After Friday's very long TC call reviewing the "star shift", "immutability symbol", and "xref" proposals (see
https://wiki.oasis-open.org/xdi/StarShift), this weekend I worked on an update to the XDI ABNF that I just uploaded to the ABNF page:
I was excited to work on this ABNF because, as I had predicated on Friday, it is significantly more simplified, regular, and elegant than any previous version. (And no longer recursive, which will finally make Joseph happy ;-)
The next step is for Joseph and Markus to review and test it carefully, and for Joseph to attend to some remaining to-dos on the low-level rulesets. There is also one open question about what versions of SHA hashing do we want to support as native XDI schemes. Please feel free to weigh on this thread with your view.
