It contains a UML (Unified Modeling Language) model of the election data and a JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) format derived from the UML model. It contains background information regarding how geopolitical geography is structured and used in the model and schemas. It also provides usage examples for anticipated use-cases. The format is comprehensive and at the same time very flexible, able to accommodate election scenarios used throughout the U.S. It is part of a series of common data format specifications for voting equipment. </div> </div> <div class="nist-block nist-block--no-margin"> <div class="nist-field nist-field--label-inline string-long"> <div class="nist-field__label">Citation</div> <div class="nist-field__item">Special Publication (NIST SP) - 1500-20</div> </div> </div> <div class="nist-block nist-block--no-margin"> <div class="nist-field nist-field--label-inline string"> <div class="nist-field__label">Report Number</div> <div class="nist-field__item">1500-20</div> </div> </div> <div class="nist-block nist-block--no-margin"> <div class="nist-field nist-field--label-inline nist-field--link-list entity-reference"> <div class="nist-field__label">NIST Pub Series</div> <div class="nist-field__items"> <div class="nist-field__item"><a href="/web/20230130122500/https://www.nist.gov/nist-pub-series/special-publication-nist-sp" hreflang="en">Special Publication (NIST SP)</a></div> </div> </div> </div> <div class="nist-block nist-block--no-margin"> <div class="nist-field nist-field--label-inline nist-field--link-list entity-reference"> <div class="nist-field__label">Pub Type</div> <div class="nist-field__item">NIST Pubs</div> </div> </div> <div class="nist-block block-top-margin"> <div class="nist-field nist-field--label-above nist-field--link-list link"> <h3 class="nist-field__label">Download Paper</h3> <div class="nist-field__items"> <div class="nist-field__item"><a href="https://web.archive.org/web/20230130122500/https://doi.org/10.6028/NIST.SP.1500-20" target="_blank">https://doi.org/10.6028/NIST.SP.1500-20</a></div> <div class="nist-field__item"><a href="https://web.archive.org/web/20230130122500/https://tsapps.nist.gov/publication/get_pdf.cfm?pub_id=936145" target="_blank">Local Download</a></div> </div> </div> </div> <div class="nist-block"> <div class="nist-field nist-field--label-above string-long"> <h3 class="nist-field__label">Keywords</h3> <div class="nist-field__item">Common data format (CDF), ballot definition (BD), ballot style, JavaScript Object Notation (JSON), unified markup language (UML), eXtensible Markup Language (XML).</div> </div> </div> <div class="nist-block"> <!-- nist-index-ignore-start --> <div data-elastic-exclude="" class="nist-tags"> <a href="/web/20230130122500/https://www.nist.gov/topic-terms/voting-systems" hreflang="en">Voting systems</a> and <a href="/web/20230130122500/https://www.nist.gov/topic-terms/information-technology" hreflang="en">Information technology</a></div> <!-- nist-index-ignore-end --> </div> <div class="views-element-container nist-block"> <h2 class="nist-block__title">Citation</h2> <div> <div class="js-view-dom-id-f613996d38c437853a30d48b6e5a3fcc141c822a325af01e93c67142e82f0f87"> <article class="bibcite-reference"> <div class="bibcite-citation"> Long, B. and Dziur艂aj, J.
