NOTICE: As of 2023-02-01 this Trac wiki has migrated to the new IETF wiki at


Wiki for the Virtual World Region Agent Protocol (VWRAP) Working Group.


The BOF preceding this WG was known as OGPX ("Open Grid Protocol"); the name was changed to eliminate confusion over the term "grid" (grid computing vs. grid-partitioned virtual worlds). Older documents may reference OGP/OGPX.
