Importing a Dataset

This guide shows how to import a Dataset, in Excel format, into the Metadata Exchange as a "Data Model".

At the homepage:

Click the login button to see the following screen:

Login to the MDX using your credentials.

You will see the dashboard:

Click the import menu button to open the import menu:

Select "Import Excel" to get to the following screen:

Here you can provide an Excel file which will be imported and converted into a Data Model.

An example Excel file is available here:

In addition to the Excel file you will also need to provide a "Headers Map" such as the one below. This "Headers Map" tells the Exchange which columns should become what sort of Catalogue Element.

For example, in LOINC,
- "CLASS" becomes a "dataClassName"/"Data Class Name" (the name of a Data Class),
- and "Component" becomes a "dataElementName"/"Data Element Name" (the name of a Data Element).
- LOINC_NUM becomes the "dataElementID" (the id of a dataElement).
- Many columns become metadata entries for particular
Generally it is assumed that a row of the spreadsheet represents one "Data Element", possibly with an associated "Data Type" and "metadata", and belonging to a "Data Class".
