Blank MODS elements from the crosswalk #117

Currently, the crosswalk creates a blank MODS element if the element it is mapped to is blank. The idea is to add logic which will cause the crosswalk to not write blank elements.

  • If/then logic: if field mapped to is blank, then don't write element set.
  • Must discount attributes with preset values, so that they don't trigger a "not blank" response.
  • Have way for users to indicate whether a subelement is important or not (e.g. only want mapped if 's field has a value, regardless of what's going on with /).
  • Have way for users to mark elements as required or not, and throw up a warning if a required element is not mapped because it's blank, indicating what line the error is from.
  • Probably use some form of recursive logic, where the system checks the parent element and all subelements/attributes and then loops back to the parent element to determine whether to write the whole block or not. (This prevents partly written metadata elements.)
