Greetings from the NAACCR XML Workgroup!
We wanted to remind you of some resources and timelines to help prepare for the NAACCR v21 implementation and XML transition. If you have questions, comments, or concerns, please submit them in the NAACCR XML Standard Forum.
The NAACCR v21 Base Dictionary is available on the NAACCR website at: https://www.naaccr.org/xml-data-exchange-standard/.
In preparation for implementation of the XML standard for NAACCR v21, central registries with locally defined data items should create and provide user dictionaries to vendors by October 1, 2020.
A user dictionary is an XML file that defines key metadata about NAACCR data items as they relate to a NAACCR XML data exchange file, their valid XML parent elements, and processing rules. The user dictionaries should include all registry-specific data items for NAACCR v21 including current registry-specific items as well as any new items planned for implementation in NAACCR v21. This will help vendors prepare customized files and software applications and reduce the chance of delay for deployment of NAACCR v21 software.
All central registries with registry-specific data items should do the following:
Central registries that do not have custom data items can fill out the form on the XML Dictionary Submission Portal and write in the Description box that they are not creating a user dictionary. These registries can submit the form without attaching a file.
NAACCR has established a User Dictionary Clearinghouse 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 and deploy their NAACCR v21 changes in a timely manner.
NOTE: These files will be shared publicly in order to provide it to the widest audience of software vendors and to assist registries in creating XML User Dictionaries as they transition to the XML standard for NAACCR v21. Only registered MyNAACCR account holders can post files, but once posted, they will be available publicly for download.
Once the User Dictionary Sample Template is filled out, it can be uploaded to the XML Dictionary Submission Portal by someone at a central registry with a MyNAACCR account that is responsible for managing registry-specific data items. Once uploaded, these files will be publicly available with the intent of allowing registry software vendors the registry-specific customizations, including codes and definitions, for registry-specific data items in their software. While codes and descriptions are optional and not defined in a user dictionary, central registry-assigned codes and descriptions must be shared with vendors in order to generate look up tables in software displays.
When assigning names to registry-specific data items, the maximum length for a NAACCR Name is 50 characters, and the maximum length for a NAACCR ID is 32 characters. The software tools available for creating user dictionaries will calculate a new NAACCR ID based on the NAACCR Name as long as the names contain 50 characters or less. Additional information can be found in the NAACCR XML Data Exchange Standard, available at https://www.naaccr.org/xml-data-exchange-standard/.
Please note that these spreadsheet templates do not take the place of a user dictionary. The templates provide a reference with information needed to successfully implement registry-specific data items with the end goal of bringing all of the information together in one place to create a user dictionary file. Once the spreadsheet is filled out, central registries with registry-specific data items must also create and maintain the actual user dictionary file.
We encourage all registries with custom local data items to complete the spreadsheet template and upload the completed spreadsheet and User Dictionary to the XML Dictionary Submission Portal. Instructions for uploading the files are provided on the website.
If you have questions, comments, or concerns, please submit them in the NAACCR XML Standard Forum.
