Can we set-up a web resource / location --> to illustrate these
architectures we're (all) talking about?

Whilst i understand the complications, i'm continuing to have issues with
the term 'blockchain'.  Part of my problem here is that the general
understanding of blockchains refer to a mechanism that requires 'mining',
which in-turn offers an opportunity to sell alot of hardware (and
thereafter use alot of energy).

Perhaps indeed, i need to simply get off it; and i know within the
'Fintech' space blockchain = buzzword --> people have budget for
'blockchain' stuff; yet on the web layer of this work, it appears modern
designs are working to take into account;


taxonomies and ontologies; security and privacy; identity; governance, use

plus much more.  From a technology perspective (rather than use-cases,
which include some of the former)

1. RDF
2. HTTP / HTTP API
3. HTTP Signatures
4. some sort of provenance / version control
5. purge functionality
6. perhaps some way of packaging the referenced ontology definition (re:
point 4) (maybe build upon LDP?)
7. variable decentralisation mechanics (ie: distribute to every
participant, distribute to group -- (1 --> n)

I would like to add also dignity (as an interoperable developmental method
supportive of privacy)

Identity (access/auth/utility - use cases) is tricky - IMHO, packaged,
signed, sparql statements in plurality offer a flexible approach to
representations of bundled 'identity constituent' statements, supportive of
persona management.

8. have we reviewed https://www.w3.org/TR/ldn/

among other things.  The goal of these study groups will be to determine

Define identity?

web (online/digital, et.al.) Identity is a nebulas, continuously evolving
permissive set of characterisations that are perceived by recipients
involving choices made by the 'subject' as to perform / elect persona
attributes within a temporally aware data space. These 'affirmations' are
likely perceived differently between participants of any one identity
related communication.  It gets more complex thereafter.

Constituents to an identity framework may includes;
- Authentication and preservation of access control
- implicit, explicit and unstructured counterparts of knowledge
representation provided on some sort of basis.
- internal/external influencers (balanced out with dignity / privacy
mechanics that may create/infer true/false pretexts)
- interferences with the confluence of structured, unstructured, accurate,
false/misleading knowledge fragments

https://www.w3.org/2005/Incubator/webid/spec/tls/ gives a relatively good
means (despite documentation aspects, particularly re: ontology use) to
define a device/account (being some devices have no accounts, and others
do); but it doesn't really identify the user of the machine, this is
currently inferred.

So, in other words, it’s very early days yet, and it will likely be several

So, we have
- ISO
- IETF (are they in the chat?)
- IEEE
- W3C
- OASIS was involved at some stage, not sure what's happening there...

I think the big thing here; is this 'identity' counterpart; i think we need
to be both particularly careful about it, but also honest and straight
forward.  The 'identity' piece, has often been over simplified and the web
has an array of characteristics throughout modern civilisation world-wide
due to these implicit decisions.

I watched it through the emergence of Web 2.0.  I think we need to consider
these variant challenges with more diligence this time around.  If we're
not going to look at that problem (or the implications of what we're doing
in how it will impact that problem); then a simple press release stating
so, may suffice.

If we're going to incorporate some thinking about these sorts of enormous
challenges...  (imho, better to have tried and failed than not to have
tried at all); then my thoughts are that the breadth of participation
(perhaps surrounding "linked data decentralised ledgers" on the
data-presentation layer) may yield better results.

I assume the use of these technologies will result in 'tamper evident',
'mathematic proofs' in machine/human readable formats for use as
'verifiable claims' as a high-level "identity constituent";

ie:
- i did this thing
- i own this
- this happened
- this creative work has properties that others support by way of digital
signature

et.al.

https://www.w3.org/Consortium/Patent-Policy-20040205/ is investable, and
has different characteristics / properties from a socio-economic
perspective.

Work required to produce such an analysis would include doing the identity
use-cases in a broad socioeconomic methodology - which isn't really a
blockchain mandate, that's something else.
