2024 Parcel Data Electronic File Transmissions

​ParcelData schema is available for download – ParcelData2023V01.zip

NEW Schema Information

  • New for 2024
    • Property assessment data must be maintained electronically in (1) the format native to the customized or uncommon software and (2) in a non-proprietary format (comma delimited text, MS-Access, DB2, SQL, XML).
    • DOR provides this XML parcel data standard that satisfies the non-proprietary format requirement
    • Note: unless specified by contract, the municipality is responsible for all costs associated with the transfer of the electronically stored data to the municipality.
    • See Chapters 7 and 8 of the Wisconsin Property Assessment Manual for additional information
  • See the ParcelData2023V01.zip:
    • Parcel data schema: ParcelData.xsd and ParcelDataTypes.xsd
    • Documentation folder:
      • Sample Files folder: two sample parcel data files
      • Schema diagram: DiagramParcelData.png
      • Field names and definitions: ParcelData.doc
      • Schema changes by date: SchemaChangeLog_ParcelData.xlsx
  • Parcel numbers
    • Provide formatted parcels numbers with punctuation (ex: "." and "-")
    • See the DOR current parcel number formats for each county
    • Acknowledgement emails contain parcel numbers when a XML does not meet the schema requirements
  • Send DOR your public (redacted) data to maintain consistency with providing any data

Prepare the File

  1. 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
  2. Submit one XML for a parcel
  3. Upload the parcel -
    • Send a single zipped file for each real estate XML
    • Make sure the zipped file only contains xml files
    • Do not include internal folders in your zip file

Transfer the Data

Send the file with file transfer protocol (FTP).

Steps:

  1. Select "No" for "Is this a test file?"
  2. Select your file with the browse option
  3. Transfer the file

Acknowledgments

  • DOR provides a receipt acknowledgment on the file transfer page
  • Contact DORDeveloperRelations@wisconsin.gov for assistance in determining causes for a file reject
  • When you contact DOR, include the file name to help expedite troubleshooting
