Genealogy software is computer software use to collect, visualize, and publish genealogical data. At a minimum, genealogy software collects the date and place of an individual's birth, marriage, and death, and stores the relationships of individuals to their parents, spouses, and children. Additionally, most genealogy programs handle source citations, additional events in an individual's life, free-form notes, and photographs and other multimedia. Genealogy software programs can produce a variety of graphical charts and text reports, such as a pedigree chart, ahnentafel report, or Register report. Some desktop applications generate HTML pages for web publishing, and there are stand-alone web applications as well. Most genealogy programs can import and export using the GEDCOM industry standard.
