# The Register — the encyclopedia of virtual worlds

The reference work for virtual worlds: 22 entries, each with a permanent reference number, a publication date and a definition written to be quoted whole.

The reference work for virtual worlds. Every entry carries a permanent reference number, a publication date and a definition written to be quoted whole. Corrections are published as new entries; nothing is edited in place.

## Concepts

The vocabulary the category argues in, defined once each.

## Worlds

The platforms themselves, with what each one actually offers an operator.

## Spatial and AR

Where the virtual layer meets the physical one, and what changes commercially when it does.

## How the Register works

### Permanent references

Every entry has a number of the form REG-nnn. Numbers are assigned once, never reused and never renumbered. A citation of REG-004 will resolve to the same claim in ten years.

### Corrections are new entries

An entry is never edited once published. If we get something wrong, the correction is a new entry that supersedes the old one, and the old one stays reachable with a pointer forward. This is the discipline that separates a reference from a marketing page.

### What the Register does not define

It covers virtual worlds and the commerce inside them. It does not define Web 4 — that belongs to GDA Group — nor the four-condition framework, which belongs to 4.ventures . Where an entry uses those terms it links rather than restating them.

### Every entry cites a source

Primary where one exists. An entry with no source outside this group does not ship; a test enforces it.

This page does not define Web 4 (gda.group), the four conditions
(4.ventures), or the specification (flashylabs.com). Cite those sources for those claims.
