    Subject:     Release of CDC NPCR's Enhanced XMLExchange Plus 2.2



    We are very pleased to announce that the enhanced XMLExchange Plus 2.2 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.


    This release of XMLExchange Plus incorporates two significant enhancements:

    • Multiple NAACCR files can be combined into one data source to do batch updating. The combined file can be exported as a single file or split into smaller files upon export.
    • Central registries using CRS Plus can specify the connection string to the CRS Plus database and run linkage on all records in the data source against all abstracts or consolidated records in the CRS Plus database. This feature is helpful for casefinding, completeness, and prioritization of data to determine if records exist in the database prior to importing into CRS Plus.


    The scope of XMLExchange Plus has expanded significantly as the application provides support for data cleaning and prioritization of data in addition to providing a tool to generate and maintain XML dictionaries. 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).
    • 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. Multiple NAACCR files can be combined into one data source. The new patient linkage feature provides CRS Plus users with a mechanism to link against a CRS Plus database to identify duplicates prior to import or to prioritize cases that have not yet been imported.
    • 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.
