Which of the following is not a typical data standard area?

• A. Owner's favorite color
• B. Address standardization
• C. Parcel ID schema
• D. Geographic coordinate system

Answer: (C)

Data standards in property data focus on consistent, interoperable domains that support valuation, reporting, and mapping. Address standardization is essential because having uniform street names, abbreviations, and postal formats makes it reliable to compare records, mail notices, and geocode parcels. A geographic coordinate system is another fundamental standard area because coordinates must be defined in a common datum and projection so that locations line up correctly on maps and in spatial analyses. The owner’s favorite color, while harmless, isn’t used in property assessment workflows and isn’t something that a standard data model would require or enforce across systems. Parcel ID schema, meanwhile, describes how parcel identifiers are constructed; while important for internal tracking, it’s not universally treated as a standard data domain the way addresses and coordinates are. Therefore, parcel ID schema is not a typical data standard area.
