[mdlug] (dis)recommendations for wiki engine

[Robert Meier]

Wiki-Wiki,

In January, I installed OddMuseWiki at work,
chosen because it required only perl and stored text pages
with creole markup.

After 3 months, as I had hoped, the wiki concept,
once seen by management as a waste of effort,
is now seen as essential.  The time is ripe to upgrade
to a more featured wiki engine.

The users suggest MediaWiki (de Wikipedia),
but my initial research suggests that without a formal markup language,
pages once imported or submitted into MediaWiki,
cannot easily be exported when the time comes
(in a few months or years) to upgrade again.

Has anyone had experience exporting content from MediaWiki
    into another wiki engine?
  Which one?
  How was it accomplished?
  How many (user-addressable) pages were involved?

Does anyone have and (dis)recommendations for a wiki content format?
  creole?

Does anyone have any (dis)recommendations for a wiki engine
  (+required -preferred)
  o with comparable feature set to MediaWiki
    + scalable to ~10,000 pages
    + searchable
      + keyword
      + multi-word logic
      - google style
  + well-defined data format
    + reversibly exportable
    - table-generation sql
    - ABNF for interpretted fields

TIA,
-- 
Bob
