Is there a mapping Between NIBRS and GJXDM?
There is a draft mapping of the 53 data elements of the National Incident Based Reporting System (NIBRS) to the GJXDM, Version 3.0, release. While many of the elements have a direct mapping, some elements are not a one-to-one match. Furthermore, in a few cases a mapping is either too complex or does not exist, and was therefore omitted.
NIBRS was created by the FBI's Uniform Crime Reporting (UCR) program, which began in 1929, collects information about crimes reported to the police. In 1982, BJS and the FBI sponsored a study of the UCR Program with the objective of revising it to meet law enforcement needs into the 21st century. A 5-year redesign effort to provide more comprehensive and detailed crime statistics resulted in the National Incident-Based Reporting System (NIBRS) which collects data on each reported crime incident.
The UCR Program is currently being expanded to NIBRS. Currently under the Summary system, law enforcement authorities aggregate the number of incidents by offense type monthly and report these totals to the FBI. Under incident-based reporting, agencies will provide an individual record for each crime reported. The Summary UCR Program collects offense information on the 8 Part I crimes of homicide, forcible rape, robbery, aggravated assault, burglary, larceny-theft, motor vehicle theft, and arson. It provides limited information about offenses, victims and offenders, and includes reported arrests for 21 additional crime categories.
Under NIBRS, law enforcement authorities provide information to the FBI on each criminal incident involving 46 specific offenses, including the 8 Part I crimes, which occur in their jurisdiction. Details about each incident include information about multiple victims and offenders. Arrest information on the 46 offenses plus 11 lesser offenses is also provided in NIBRS. Since NIBRS place such a crucial role in the activities of FBI, it is very important that the link between the NIBRS elements and GJXDM elements are clearly defined.

Note that the Incident Reporting Reference IEPD, created by SEARCH, has been validated to map all 53 NIBRS elements.
