We have a piece of software that takes client provided data and processes it. A lot of times our client's data will fail because the data in a particular field is either too long or missing altogether. We're creating a system that will truncate the field value if it's too long or infer the value if it's missing. The data may still fail validation at some later point but we don't want the data to fail because it's too long or missing. This will be done before anything else is done to that data.
I'm trying to think of a name for the new system that will represent what we're doing. I don't want to name it something like "ModifyField" because we modify the data for other reasons as well.
To be more specific, I'm looking for something that can serve as a method or class name in the code.
