Barry, I took some time today to re-read every technical item posted here since your mail of March 23rd, and this is how I would summarize our recent burst of activity: - It seems that there is significant unhappiness about LLSD, for a range of reasons. Some are wondering why we are creating a new ADT rather than using an existing one like Protocol Buffers, while others are worried on a deeper level that LLSD is too rooted in SL legacy and gives us very little for the future. (I did not voice an opinion on that subject in this round, but I have in the past expressed worries about LLSD extensibility.) - All discussions now seem to be taking multiple worlds into account, which is a huge step forwards for interop and should serve us well for document writing, We are periodically giving assurance that "nobody is going to force you to interoperate", although that should really be obvious even to casual onlookers since denying interop is so easy. Additionally, it is our stated goal to support all deployment patterns, and the walled garden is one of those. - We have ascertained that we are not "writing docs just to write docs", but only docs that reflect consensus. Your description "tease consensus out of discussion and write it down" was very appealing. We are still at the teasing stage, but I do sense a convergence coming. - An attempt was made to gain a priori agreement to always accept superset requirements in VWRAP, or to put it another way, to adopt a group mantra of "design for tomorrow". I'm still not really sure whether it was the concept itself which attracted strong opposition (which I think would be most regrettable) or if the arguments were merely about choice of words. - Vaughn's wonderful protocol flow diagram kicked off an excellent discussion about protocol details. This was (remarkably) the first time we had ever discussed the asset access protocol over these 2-3 years of work, and it led us to examine two very important issues: (i) eliminating the burden of capabilities when there are no access restrictions on an asset, and (ii) separation of assets into metadata and content. This got us much closer to the real core of VWRAP than we have ever been, namely the asset services. - A previously unmentioned optional requirement appeared in the discussion: simulation consistency. Although optional, our protocol will need to allow it to be achieved (to the extent possible) when it is demanded by a region. Given all the above (and many other things discussed in passing), I am not at all unhappy with recent progress, and indeed it could be said that we achieved more for interop in 2 weeks than in the previous 2+ years. With regards to writing documents, we're still teasing out the technical details, but as we do this, our more general goals are starting to solidify as well, so I think that an Intro doc will come in due course. I do accept that this isn't happening very rapidly, but with so few bodies assisting in the analysis, it's hard to do better. Nevertheless, I think that we are achieving something useful. We may be even be close to condensing the recent discussions into a paragraph or two, because full solutions are not needed for an Intro.
