It structures and defines metadata properties that allow users to add precise and reliable data about images.<\/p>\n<p>In the early 1990s, the original \u201clegacy\u201d <strong>IPTC-IIM<\/strong> (Information Interchange Model) schema was developed to organise, systematise and unify the way information was stored and transported with images. Prior to IPTC-IIM, every management system had its own way of handling metadata, which did not transfer data between other software and file formats.<\/p>\n<p>Today, the IPTC Photo Metadata Standard consists of two schemas &#8211; <strong>IPTC Core<\/strong> and <strong>IPTC Extension<\/strong> \u2013 which were built on the legacy of the original IPTC-IIM, and developed by the IPTC for professional use with a focus on news and stock photos. IPTC worked alongside Adobe on the technical implementation of the metadata that employs Adobe&#8217;s <strong>XMP<\/strong> technology (now an ISO Standard) as an enriched alternative to the IIM format.<\/p>\n<p>IPTC Core and IPTC Extension define metadata properties with comprehensive sets of fields that allow users to add precise and reliable data about people, locations, and products shown in an image. It also supports dates, names and identifiers regarding the creation of the photo, and a flexible way to express rights information.<\/p>\n<h3>Reference Images using all IPTC Photo Metadata fields<\/h3>\n<p>You can view and download an image file which includes all metadata fields defined by each version of the IPTC Standard:<\/p>\n<ul>\n<li><a href=\"https:\/\/iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2025.1.jpg\">Reference image for IPTC Photo Metadata Standard 2025.1<\/a><\/li>\n<li><a href=\"https:\/\/iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2024.1.jpg\">Reference image for IPTC Photo Metadata Standard 2024.1<\/a><\/li>\n<li><a href=\"https:\/\/iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2023.2.jpg\">Reference image for IPTC Photo Metadata Standard 2023.2<\/a><\/li>\n<li><a href=\"https:\/\/iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2023.1.jpg\">Reference image for IPTC Photo Metadata Standard 2023.1<\/a><\/li>\n<li><a href=\"https:\/\/iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2022.1.jpg\">Reference image for IPTC Photo Metadata Standard 2022.1<\/a><\/li>\n<li><a href=\"https:\/\/iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2021.1.jpg\">Reference image for IPTC Photo Metadata Standard 2021.1<\/a><\/li>\n<li><a href=\"https:\/\/iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2019.1.jpg\">Reference image for IPTC Photo Metadata Standard 2019.1<\/a><\/li>\n<li><a href=\"https:\/\/www.iptc.org\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2017.1.jpg\">Reference image for IPTC Photo Metadata Standard 2017.1<\/a><\/li>\n<li><a href=\"\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2016_large.jpg\" target=\"_blank\" rel=\"noopener noreferrer\">Reference image for IPTC Photo Metadata Standard 2016<\/a><\/li>\n<li><a href=\"\/std\/photometadata\/examples\/IPTC-PhotometadataRef-Std2014_large.jpg\" target=\"_blank\" rel=\"noopener noreferrer\">Reference image for IPTC Photo Metadata Standard 2014<\/a><\/li>\n<\/ul>\n<p>If you check this image with some imaging software you should see a value of the field reflecting the name of the field.
