Kailye logo



This site describes a full set of systems useful for allowing an interoperable assembly of all the virtual worlds: the Metaverse, where an user will be able to teleport to any of the worlds, with the same identity (federated identity) and the same viewer (interoperable worlds). These are the basic condition to the success of virtual worlds, in the same way as the http system did the success of the Internet.

Main divisions of this site:

Manifesto of the virtual worlds: Claims for the technical, legal and administrative conditions and tools to have a working metaverse.

The WEM system (World Entry Management): How are managed identities, connexions and teleportations between worlds. The administrative system and the technical system.

The kailye interchange language: A proposal for simulators and viewers to communicate in real time

Roadmad for the implementation of the whole system For now, enumeration of tasks.

News of the Metaverse


General Introduction and purpose of this site

The emerging domain of virtual worlds is today blocked by the lack of a generally available system, which would be especially standard and interoperable, providing all the necessary tools and conditions for all users to appropriate the virtual life, and not depending on only one company or interest. Only standards playing a similar role of the HTTP system will allow the Metaverse to really take off, in every domain, whatever for games, social, art, personnal life, business, science, techniques.

However virtual worlds are much more complex than Internet pages, as a 3D connexion involves several links to different resources: world description, chat system, audio channel, etc. It also involves many issues such as speed, ease of use, safety, etc.

Especially a strong requirement is not to do again the mistakes of the 2D Internet, where copyright theft, spam, privacy exposure, anonymous bullying, bugs, etc. are the main limits in many applications. These may have still worse effects in the Metaverse, which adds an eye contact between users, and even a «physical» contact. So we must think from the very start at built-in safeties, without waiting for laws forcing us to painfully rewrite all our systems.

So the purpose of this site is to point at a clear and complete list of technical, human or legal requirements, as far as describing some companies plans or software requirements, up to a messaging language. The whole thing is into an open GNU GPL license to keep it available for everybody. And now everybody is free to select one of these tasks and take a constructive role into the building of the metaverse.


Update: the situation in November 2015

With time and the appearance of new opportunities, the creation from scrap of a language such as the Kailye is much less needed. Other well-established languages could do the trick, as for example JSON. However, we can still read profitably my description of the Kailye, for the numerous clarifications of the functions of our virtual life. The numbers compression and keyword that I propose also keep their usefulness.


On the removal of the limitations imposed by Second Life, we hardly moved: still no federated identity, no teleportation between worlds without abandoning our copyrights, and still this horrible system of square «sims». The only significant advance is the use of video streaming as I proposed, but under very limiting conditions (payment on spent time, which quickly becomes more expensive than buying a graphics card).

Contrary to all the speculation, Second Life remains the largest, despite their four times higher prices and their new TOS appropriating our creations. However it is the «self-fulfilling prophecies» about the decadence of virtual life which actually discouraged a lot of users, all worlds together.

As a result, Inworldz was forced to delay some badly needed progress, while it was expected to become the industry leader able of imposing the best solutions. But it still remains by far the best choice.

Open Sims hardly moved either: wishful thinking remains our only protection against intellectual property theft, and the earth-shattering announcements of crushed prices remain short-lived. Clearly these prices are not sustainable, and Inworldz remains the only one to have a team of developers.

However encouraging signs appear, like Inworldz being used by professionals, in recognition of his technical capacity and its good human reputation. Open sourcing its simulator also allows for a diversification of hosting. So that we can hope that the current stagnation is on the end.


Update; the situation in October 2012

This proposal WEM-Kailye was made in 2009, at a time when there was no credible alternatives to Second Life. But since then, many other virtual worlds have emerged, based on «Open Sims», a free version of the Second Life simulator. Among them, «Inworldz» stands out, both for its technical quality and its warm community.

Under these conditions, my WEM-Kailye proposal seems less urgent, less needed. However, it should be to forgotten too quickly that many of its bases are far from being addressed: -A plurality of worlds hosting, or personal hosting. -Legally protected federated identities -Ability to navigate from one world to another (hypergrid, in the process of being developed by Open Sims, but which faces problems of safety and copyright protection) -Getting rid of the terrible division of worlds in a «grid», to offer a real freedom of landscapes. -A messaging system between simulators hosted in different locations, to manage characters, collective landscapes, elements under copyright, portals, etc.

I also remind that my proposal WEM-Kailye is a total overhaul of the entire system, to eliminate the many arbitrary limitations of Second Life, and enable the integration of modern possibilities. However, this requires a certain investment, before reaching a standalone system. In contrast, Inworldz is rather a gradual evolution of the software. This solution seems more practical, and especially the only financially viable for a small company which has its customers as only support. Just that Inworldz did not expected that that they had to spend one year to completely rewrite the software of Open Sims.


Why the name «Kailye»?

Kailye is a kind of acronym of the elven sindarin words «Kaimel Alye» which literally means «To Dream Together». This may be the best elven translation of «Going virtual», but this also sets the mood: we are in virtual worlds to do things that we cannot do in the physical world, such as being more beautiful characters, more kind, more wise. And the author of the Kailye language created it with the explicit purpose to offer better life experiences in the virtual, which would ultimately drag the physical society forward.

In July 2009 I asked permission to both the Tolkien estate and Harper publishers to use these words, with no reply until now. So I assume that using the name «Kailye» is ok, while being not so sure about the full name «Kaimel Alye».
