    Subject:        Release of CDC NPCR's Enhanced XMLExchange Plus


    We are very pleased to announce that the enhanced XMLExchange Plus is now available!  This version replaces the previous version available on the CDC NPCR Registry Plus website, and the web page has been updated.


    XMLExchange Plus is a tool for reading and writing data exchange files formatted according to the NAACCR XML Data Exchange Standard.

    Tasks performed by XMLExchange Plus include:

    • Create User Dictionaries/Dictionary Maintenance. This module is intended to help users who are not XML experts produce valid NAACCR XML dictionaries. This audience includes metafile administrators who may be asked to define a user dictionary based upon customized data items collected by their registry.
    • Convert. This module converts data files from the flat-buffer format to NAACCR XML format, from NAACCR XML format to flat-buffer format, and from NAACCR XML format to delimited.
    • Run EDITS. This module runs EDITS against a NAACCR XML data file and creates a GenEDITS-style report (detail and summary).

    This enhanced version fixes an issue identified in the record layout for grouped data items and includes the following new features:

    • Import, View, Update, Export NAACCR Data. This module allows users to Import NAACCR files, view the data in a grid, update individual records in grid cells or apply batch updates for file manipulation, export updated files with or without application of filter criteria, anonymize confidential data, and includes a feature to split files by number of records or by a field value.
    • Validation. This module runs schema validation to verify the xml file is a valid NAACCR xml document and that the file does not contain any data items that are not defined in the base or user-defined dictionary. It also validates the data type and length of each data item and produces a validation report.


    For more information about CDC NPCR's XMLExchange Plus, including system requirements and installation instructions, please visit our product website at the following location:

    The install contains a PDF version of the XMLExchange Plus Manual that can be accessed from the Help menu in the task bar.  The install also contains the NAACCR XML base dictionary for the current version of the NAACCR XML Standard.

    Central registries and other data collection entities with a need to create local user dictionaries are encouraged to download the application and to review the process to create user dictionaries. We also encourage central registries to review existing local data items to determine if reporting needs have changed, and to prepare user dictionaries if you have not done so already.  As a reminder, a User Dictionary Clearinghouse is hosted on the NAACCR website to show examples of user dictionaries from other central registries and to provide the User Dictionary Sample Template that will help central registries gather information needed to define their own XML User Dictionary. Central registries with registry-specific data items are encouraged to fill out the Excel template and upload it to the XML Dictionary Submission Portal with a corresponding XML User Dictionary so that registry software vendors can get access to these required files to prepare customized software applications and to deploy their NAACCR v21 changes in a timely manner.
