The following module was proposed for inclusion in the Module List:

 modid:       Data::Validate::Item

how does this compare to Data::FormValidator, CGI::Validate, and
Attribute::Params::Validate?

Thanks for your helpful comment,

These three modules are all intended to validate user input to forms.

Data::Validate::Item is intended to validate values in records.

Typically we would be reading in a large flat file, say a CSV file, split into records by lines like this :-

ID,Sex,Age,Diagnosis,Procedure,Date,Admission_type
1,1,33,147.2,76.19,01012000,5
[snip several thousand lines]
15444,2,42,256.3,45,12,12312000,3

The problem here is to locate the four records where say sex is recorded as 3, and do something about them.
This module allows you to specify what are legitimate values for each item in a record, and either validate or transform them.
