Immersive worlds range from the simple Twitter to Facebook to the 3D richness of Second Life. They immerse you in their own world of information to form relationships, social networks, and even objects, most of which remain tightly bound to the specific world. This limits the information's value and ultimately the value of the immersive world. Semantics create meaning that release the world's information from its own technical gravity, allowing enrichment, extensions, and unification of what ultimately becomes your immersive world - a world that you control based on your meaning or semantics.

We outline an architecture, detailed examples, and transformation guidance to establish semantics that bridge and enrich multiple, immersive worlds. The generalized semantic immersive architecture illuminates three detailed examples; improved training through semantic enrichment, improved situational analysis through semantic tagging, and improved immersive worlds through semantic integration. The semantic approach improves the use and exchange of information formally bound to a specific world - this freedom makes your valuable information more useful and more powerful.
