What is the Semantic Web?

It still seems important to figure out how to describe to 'unlearned'
people, 'what is semantic web'.

I guess; essentially, what's kinda required is seemingly something that
addresses the following;

1. history of it
2. purpose of it
3. support for it / how its presently used (market penetration / abundance,
etc.).
4. implications of it
5. evolution of it (ie: non-http URIs?, etc.).

perhaps ideally also
- differences from RDBMS
- Relationship to 'AI'
- 'unmet challenges' as told by 'tech inventors' (meaning - an opportunity
to seek-out some shared values statements about the purpose of our works,
for humanity, for our biosphere, for the betterment of good).

any links?  or is anyone interested in collaborating on producing something
that's useful for others?

(NB: i note the former emails, but haven't had time to respond yet).

more broadly; my thinking is, that communicating these sorts of things
(leading to conversations about 'ontologies', etc.) may be part of the more
important steps involved in progressing works, towards a future (world/web)
we want.

Moreover also; that parts of what is thought of as RWW (by those involved
from so many years ago) may also be woven into the consideration /
deliberations, provided by the 'what' as to better explain the 'why'.

Historically; W3C has played a vital role (and will continue to do so) with
respect to patent pool creation and governance as to support future
ambitiously targeted outcomes - such as retaining 'freedom of thought' as
may otherwise be influenced by WWW related technologies including 'AI'.

Yet, i'm not sure there's much that now needs patent pool creation /
approval / consolidation / consensus.  Overall, it seems that there's a
strategic, tactical and pragmatic process of improving documentation that's
kinda distinct to seeking royalty free use of intellectual property that's
critically important for the protection of human rights / freedom of
thought / rule of law / liberalised democracies, etc.

If i'm mistaken, let me know; but IMO, tech in and of itself is
ideologically agnostic. Therein, (imo) the widespread deployment of tech;
provides a fairly comprehensive basis to consider how 'SemWeb tech' could
be used; without necessarily illustrating (or documenting) other (better?)
ways it could be used.
