Schema Information


2022 Summary of Changes

  • No schema changes for 2022
  • Can submit real estate XML with one parcel (ex: counties with a split municipality and the XML has one real estate parcel in the XML)
  • Acknowledgement emails now contain parcel numbers when an XML does not meet the schema requirements
  • See our filing assistance document available on our website
  • Reminder: Send DOR your public (redacted) data to maintain consistency with providing any data

Prepare the File

  • Name each XML with its corresponding DOR Co-muni code – to improve the XML names and quickly identify which file belongs to a specific municipality
  • Submit one real estate XML and one personal property XML for each municipality – to make the XML easier to locate when working together to troubleshoot issues
  • Upload the county - send a zip file with all municipality XML included
    • Send a single zipped file for each real estate XML and each personal property XML

    • Make sure the zipped file only contains xml files

    • Do not include internal folders in your zip file

Acknowledgments

  • DOR sends acknowledgments by email
  • The acknowledge email, stating we accepted or rejected the file, contains the file name as it is stored in our system
  • If the XML does not meet the schema requirements, the acknowledgement will provide both the Record Number and the Parcel Id causing the reject
  • When you contact DOR staff, include this file name (from our email response) to help expedite troubleshooting, especially when the file does not use the Co-muni code or if the number or file contains an error

DOR Review

  • Test files are processed individually
  • To help us respond to questions, DOR's acknowledgement email contains the file name as it is stored in our system

If you have any questions, contact us at OTAS@wisconsin.gov or (608) 266-7750.
