We've just submitted the seminar report to Schloss Dagstuhl a couple of weeks back, it should be published soon.

It’s an ambitious task, but we’ve already started to work towards it. :-)

Hello Melvin,

Do you have a link to watch the Web seminar?

Cheers,

The famous example of this was the so-called "crypto kitties" which were cats that had lives, could breed, be bought and sold etc.  This system struggled to scale, but a web version could work better

It's an autonomous agent that happens to play chess.  Another thing it could do is move the robot arms, or solve a maze.  With all the code, history and state, part of its own identity

Should we think about doing the same for agents, and indeed, giving each agent it's own unique URI, with its own life cycle?

>>
>> I'd love your input on this.  My experience of programming web based agents is that they have a maintenance overhead, such the autonomy is not really practical, I may call the ones I've made semi-autonomous.  This is akin to the desktop paradigm, where you might start an app, use it for a while and then shut it down (agent lifecycle).  I am quite interested in another style of app, where it runs as a daemon, e.g. in the system tray.  So you run it, and it keeps going in the background.  When you shut your machine down it'll stop, and reboot the machine it runs on startup, so it's kind of always there, you don thave to worry about it, like a daemon
>>
>> Multi agent systems that run more or less as daemons against the web as a (read-write) state machine have the advantage of much lower maintenance, and interesting emergent features as they become more autonomous and interact with each other.  The system itself would be modular, with reusable components that could be composed together either into a composite agent, or different parts running remotely.  They would also adapt to change, and be backwards compatible with the existing web (of data)

Some would maybe think that already single agents doing useful things on the web would be a step forward.  A more webby rough introduction in which I was involved could be a tutorial at the IoT conference [1].  In my echo chamber, we often use Linked Data-Fu [2] for rule-based simple reflex agents.  I have CC'ed Andrei who may give you some more pointers from his perspective.
