To me the Web, particularly the Sem Web is a universal space whose key
advantage is interoperability.

So, each world can interop with similar worlds.

Also worlds can operate with other parts of the Semantic Web Space.  I
use the acronym SEMANTIC to describe key areas:

Nearby services
Information management

So a game can be social, have trading with virtual currencies and
markets, you can interact with a personal or public web of trust, with
existing information or things in the real world in your locality (eg
augmented reality), using web standards.

Granted each area on the list is still in an embryonic phase.  But
this is a level of interop simply not available in other systems.

We've seen linking of basic social and trust in PHP+HTML (facebook)
and social and entertainment (zynga) get some traction.  But when we
have interop across all areas we'll have a that much more powerful

Yes, agree, leverage interop.

You dont need smart servers, just socially aware cloud storage.  Flat
files are fine, you can let Agents do all the middleware.

This is game logic.  It need not reside on a server.

Im working on an economic aspect.  This is an interesting proposal on
transactions and contracts:


I have reasonable confidence we can introduce a sophisticated economy
that can be leveraged by all sem web projects, probably before end of
next year.

Many ways to model this, again agents can handle this.

Traditional architecture is

client <--> middleware <--> data store

Web oriented architecture is more flexible and can have, in addition:

client <--> data store
client <--> agent <--> data store
client <--> data store <--> agent

With trust and PKI regulating actions.  Of course we see why WebID is
important here too.
