I'm thinking of four models for including user content in MOUL.
1- The discovery model - already discussed abundantly.
IC: An explorer finds a book to a previously unknown Age. This is submitted to the DRC for acceptation. If deemed worthy, Maintainers are sent to it for some time. If deemed safe, DRC adds the linking book in the Library in the City.
OOC: A team makes a new Age, publishes it to ULM. After peer review, a MOUL version is submitted to Cyan. If Cyan likes it and can use it, it adapts it to its taste and needs, then puts it on a test server for QA by the Maintainers, after which it schedules the Age for a future update.
2- The Teledahn/Sharper modelIC: The DRC finds a book to a previously unknown Age. They hire a team for restoring the Age and make it safe for explorers. The DRC receives progress reports and does occasional visits. When the restoration work is completed, Maintainers are sent to it for some time. If deemed safe, DRC adds the linking book in the Library in the City. Restoration journals similar to Sharper's journal are kept and publicly available so anticipation is great among explorers.
OOC: Cyan has specific needs for an Age and hires a team of volunteer builders (possibly through the GoW). If a team picks up the job, Cyan gives them a complete list of requirements and a partial Age (geometry, general layout, linking point, possibly some texture files, objects, python code). Versions are delivered to Cyan according to the current scheme (model, texture, wiring, etc). There is no peer review. A final version is delivered, which Cyan puts on a test server for QA by the Maintainers. After QA, it schedules the Age for a future update.
3- The contest modelIC: to further advance the restoration of the City or available Ages, the DRC opens a contest similar to the stained glass restoration contests. The theme would be in the lines of "Restore the room behind the door on the second landing of the great stairs". The DRC would specifiy the room measurements, function and other constraints. At some undisclosed point in the future, the door would be unlocked and we could explore the winning entry.
OOC: Same as IC except Cyan would publish a prp with a correctly sized and shaped room for fitting behind the door (maximum size, the submitted room could be smaller). The winning entry would be put on a test server for QA by the Maintainers. It would then be secretly added in a monthly update. This would encourage continual exploration. New explorers would stand a good chance of discovering it, whereas we don't try to open doors anymore.
4- The original Age modelIC: Since the restoration began, a few explorers have started studying the Art of Writing. They are rediscovering the Art from scratch much as Gehn, Atrus and Catherine have done before. As they gain experience and expertise, their work is submitted to the DRC for acceptation. If deemed worthy, Maintainers are sent to it for some time. If deemed safe, DRC adds the linking book in the Library in the City. Most of the new Writers have joined the new Guild of Writers, an organization providing help and feedback, as well as ways for all explorers to view the work in progress and provide comments and suggestions, and even lend a hand. In that way, the new Guild is much different from the old one, having shed the secrecy and elitism which used to caracterize it.
OOC: This is the simplest model, in which entirely new concepts are being developed. These may or may not fit with Cyan's storylines. Accordingly, these Ages would be available to players who don't mind the risk of breaking the continuity or suspension of disbelief. There would have to be a way of ensuring new players couldn't end up on these Ages by accident, without being warned. For example, the linking books could be stored in a reserved level of the Library, or an entirely different building with posted warnings. I entirely subscribe to Belford's ideas about original Ages being freely available for everyone in an entirely transparent process (see his post
here. This is pretty much the same model as #1, except there would be no secrecy at all because the Age would not be intended to gather any official status. This sentence in the IC section " If deemed worthy, Maintainers are sent to it for some time. If deemed safe, DRC adds the linking book in the Library in the City." actually means only "if the Age isn't bugged".
--------------------------------------------------
Note 1: These four models are not mutually exclusive.
Note 2: These are just models, not detailed processes.
Note 3: Model 3 is fascinating but much more risky, as a bugged entry could crash the whole City (unless it's in a separate prp file?). Also, there may be a reason why Cyan hasn't provided new content in the City since the original Live. Maybe the City can't be developped further for performance reasons, or maybe the current model is so bugged that any more fiddling with it is hopeless.
