    119119- A repository or other source that has its own data format that does not match ours.
    120 A means of mapping from the source's schema to ours will be needed.
    121 It is likely, for an existing source, that we will produce the schema mapping.
    122 Would want to detect schema changes, or get notification of them.
    123120
    124 - A user who wants to upload data, and is willing to format it to our specification.
    125 In this case the data can be processed without a schema mapping.
     121- A user who wants to upload data, and is willing to format it to our specification,
     122  i.e. use our table and column names.

    127124==== Data structure uses cases: ====
     
    175172- Any combination of the above.
    176173
     174=== Schema mapping ===
    177175
     176- If the source has a schema that does not match ours, a means of mapping from the
     177  source's schema to ours will be needed, or will have to be inferred.
     178  (It is likely, for an existing major source, that we would write the schema mapping.
     179  For such a source, if we were receiving updates from them regularly, we would want
     180  to detect schema changes, or get notification of them.  But for a source we draw
     181  on regularly, there may be better means of pulling data than CSV files...)
     182
     183- If the data uses our formatting, we don't need a schema mapping -- we just need
     184  to be told it's our formatting.
