MMOX

"MMOX is an effort to collect best practices and develop consensus based standards for virtual world and MMO interoperability. The mmox@ietf.org mailing list is for technical discussions related to this objective and for coordinating administrative details of upcoming meetings." -- IETF MMOX listinfo

This page is intended as a useful container for gathering together links to MMOX resources.

Please expand it with other relevant links that could be helpful. (Don't lose any links. :P)

Highlighted contributions

Unavoidably, these reflect personal interests, but feel free to add your own to the set.

• Introduction, from Chairperson -- purpose and goals
• Introductory words, from Area Director -- IETF perspective
• MMOX Charter, Scope, Activities, from Chairperson -- a visionary synthesis
• MMOX: Strawman scope/goals/approach -- extended analysis of MMOX issues, IETF draft
• MMOX List moderator and participation info -- clear statement by AD on participation
• Taxonomy of topics -- statement by Infinity that the intention of MMOX was to create an OGP standard
• Taxonomy of topics, thread -- examination of the implications of Infinity's post
• Chartering for requirements only -- first proposal for MMOX group split
• MMOX Progress Tracking -- review of recent draft-centered activity @ 2009-Mar-4
• Debunking "Universal Client" -- also explains why generic clients are completely inevitable
• Managing model mismatches -- methods for achieving interop despite model mismatches
• Scalability considerations / BCP95, BCP22 -- IETF statements on scalability, relevance to MMOX
• 3-world OGP interop scenario -- description of an OGP-based interop scenario over 3 virtual worlds
• Decomposition of teleport into its essential components -- details how teleport is applicable to all VWs
• Creating walled gardens considered harmful -- a plea to avoid non-interop segmentation under MMOX
• James Kempf's horrifying (but entirely plausible) scenario -- should we abandon MMOX?
• "I don't know what OGP is", by Diva Canto -- eye opening post from key Opensim developer

Requirements tracking

• Unifying object execution models -- requirement to support both local and remote execution models
• Exposing regions -- requirement that exposing implementation of regions not be mandatory
• Avatar diversity -- requirement for transport of avatar visual information between virtual worlds
• Hierarchical objects -- mentioned in passing in MMOX, needs a formal requirement expressed
• A Mission Statement for the IETF -- requirement for scalability, wide deployment, interoperation
• Interop Metrics and MMOX Goals -- quantifying the interoperability requirement as a metric
• Trust Agreements vs Secure Data Transfer, prev -- replacing security theater by actual security
• Decoupling Asset Storage -- asset storage/inventory needs to reflect the diverse origins of objects
• Basic region requirement to support portals -- this also allows user-defined region adjacency
