Implement common data enhancements as transformations

Implement common data enhancements as transformations, so that they can be easily applied to the original data set when it is updated.

For example - City A uploads crime data, where one field is IN ALL CAPS. User B painstakingly rewrites this field as lowercase, except for the first letter. City A appends newer data. Now, part of the data is Pretty and part of it is UGLY. Unless User B goes back and updates the data again, it will be in mixed formats - and that would be an abomination.

If there was a way to specify the desired transformation, it could be automatically applied every time the data was uploaded (assuming the uploader approved the transformation).

Specifying a transform:

• choose from a drop-down menu of common options
• submit a code fragment that will be applied to each entry

(Forgive me if this feature exists or is in the works - I saw the video on CfA and this idea popped into my head)

Keep up the good work!

The issue names no files, tests, or entry points. Start by reviewing how datacouch handles dataset updates, then clarify the supported transformation options and approval flow; done means approved transformations are consistently applied to newly uploaded data.
