Sounds like a plan.

Re: VCWG work (verifiable claims) it seems kinda important the
intepretation is retained; or that the signed-instrument be able to be

Perhaps via: https://www.w3.org/TR/ldn/ ??

dependency graph;
1. gen signed Verifiable Claim ("VC") (incorporating RDF + Version ID)  -->
What's the relationship thereafter with LDN/LDP?

2. definition is updated, mechanism (ie: LDN) used to provide the option to
update VC with new definition? --> interesting workflow considerations...

yup. guru. i know. ;)

yup.  working on a tool concept around 'RDF sentences'
https://lists.w3.org/Archives/Public/public-schema-gen/2017Mar/0001.html  |
but not much to report yet (just finished www2017 event work); still early
stage concept.  "foaf" context concepts are kinda temporal imho, or
'squishy', as you put it.  some consideration was made about the potential
to cg the concepts therein; somewhat moreover relating to owl / sparql
scripts, perhaps packaged in ldp containers?

version control (other than using github) seems like an emerging issue.
Was thinking maybe it's a problem for the LDP group, do you have any
thoughts on the matter?

packaging the definitions may bloat 'blockchain' methods, yet it's kinda
important the context is retained within a 'trust' instrument (as to
maintain the means for intended interpretations).  Herein/hereafter,
decentralised discovery considerations.  I'll be constructing a document
with snippets from various docs produced over time to a more concise
overview of thoughts in the area, taking into consideration some of the
other lifecycle dependencies in a manner i'm hoping will lead to
progressive outcomes...

The RDF sentences concept - seems like bit of an (interesting) mission.
