    265265Some notes and cautions:
    266266
    267 - Ideally the (internal) schema mapping will be "runnable" -- that is, it can
    268   drive the extraction of data. Actually producing a state machine or similar is
    269   likely overkill.
     267- It would be convenient to have the (internal) schema mapping be "runnable" --
     268  that is, able to drive the extraction of data. Actually producing a state
     269  machine or similar is likely overkill. ;-)
    270270
    271271- Error handling and feedback must be done without user intervention -- this may
     
    274274- Need to provide error info in a machine-readable form.
    275275
     276- The data may contain duplicates, or near duplicates. The spreadsheet importer
     277  attempts to detect duplicates, and gathers them up for the user to decide on.
     278  But because this may operate with no human do de-dup the data, we should
     279  expect to find and deal with dups.
     280
     281- There may be missing data or malformed data -- again, error messages should
     282  be in a machine-readable form.
     283
     284- Besides the repeated parent records that occur in an outer join, there may be
     285  multiple records that can be recognized as refering to the same entitiy,
     286  that each have partial information. It may be appropriate to merge / aggregate
     287  these into more complete records. This should be part of the napping.
     288
     289- Need to handle security, e.g. is the source authorized to update or create
     290  the tables / fields they're trying to act on?
