- Convert: A user configured transformation, specific to file attributes (see below)
- Convert Type: Transformation not specific to file attributes
- Global Template: A transformation for any file type that fits

- Does it have a convert schema? If so, then use it.
- Convert type
- Client
- File type/format
- Length of lines or columns, depending on file type
