clacke: exhausted pixie dream boy 🇸🇪🇭🇰💙💛<p>TIL there is something called IPTC IIM/XMP</p><blockquote>> [ . . . ] Almost all the IIM attributes are supported by the Exchangeable image file format (Exif) [ . . . ]<br>> IIM metadata can be embedded into JPEG/Exif, TIFF, JPEG2000 or Portable Network Graphics formatted image files. [ . . . ]<br>> IIM's file structure technology has largely been overtaken by the Extensible Metadata Platform (XMP), but the IIM attribute definitions are the basis for the IPTC Core schema for XMP.</blockquote><p><br><a href="https://en.wikipedia.org/wiki/IPTC_Information_Interchange_Model" rel="nofollow noopener noreferrer" target="_blank">en.wikipedia.org/wiki/IPTC_Inf…</a></p><p>Not sure what this means exactly. Is IIM backwards-compatible with EXIF where they overlap? There's a mapping between them?</p><blockquote>> XMP can be used in several file formats such as PDF, JPEG, JPEG 2000, JPEG XR, GIF, PNG, WebP, HTML, TIFF, Adobe Illustrator, PSD, MP3, MP4, Audio Video Interleave, WAV, RF64, Audio Interchange File Format, PostScript, Encapsulated PostScript, and proposed for DjVu. In a typical edited JPEG file, XMP information is typically included alongside Exif and IPTC Information Interchange Model data.</blockquote><p><br><a href="https://en.wikipedia.org/wiki/Extensible_Metadata_Platform" rel="nofollow noopener noreferrer" target="_blank">en.wikipedia.org/wiki/Extensib…</a></p><p>Again I assume this means there is some mapping between the XMP data model and whatever means of adding metadata each of these formats has. And "alongside" ... just means the fields can coexist, or are core XMP fields literally the same mapping as IIM and IIM is to the extent it's possible mapped to existing conventions in the pre-existing namespace for each format?</p><p><a href="https://libranet.de/search?tag=IPTC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>IPTC</span></a> <a href="https://libranet.de/search?tag=IMM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>IMM</span></a> <a href="https://libranet.de/search?tag=XMP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>XMP</span></a><br><a href="https://libranet.de/search?tag=IPTCIMM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>IPTCIMM</span></a> <a href="https://libranet.de/search?tag=IPTCXMP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>IPTCXMP</span></a><br>♲ <a href="https://demon.social/@vyr/111143589900004509" rel="nofollow noopener noreferrer" target="_blank">demon.social/@vyr/111143589900…</a></p>
