Hi David

It is correct that neither Manager nor EntryClient checks the datafile for consistency upon opening.

We are thinking that this type of check will be available as a tool within Manager and/or Analysis. Since these are the programs used by the project maintainers.

Please feel free to discuss if this is sufficient or another solution is better.

Kind regards,
Torsten Bonde Christiansen.

Hi,

Using the new data manager and client it is possible to create a data entry system, enter data, then add labels that don't match the labels. E.g. enter "dogs", "cats", "cows" then add labels for that field that only has "dogs" and "cats". This results in the labels defined in the XML file not matching the previously entered data. One solution is "don't do that!" but at the moment it is too easy to do so, possibly accidentally. I've certainly seen situations where a data entry system has evolved. Removing a set of labels removes the link between the labels and the field (and warns before doing so) and I wonder if epidata should also warn when creating this inconsistency. It could potentially mean a lot of checking if the data file is large and the set of labels is used for many fields. I wouldn't want the system to over-write any data, but perhaps have a way of reporting which fields and values are inconsistent with the label set.

David
