The latest version of the International Press Telecommunications Council IPTC’s Photo Metadata Standard includes two new properties: Alt Text (Accessibility) and Extended Description (Accessibility). These will make it easier for software companies, publishers, and website developers to make websites and electronic publications more accessible.
“A major milestone in accessibility is realised through the inclusion of embedded alt text and extended descriptions as IPTC metadata for digital images,” said Beth Ziebarth, Director of Access Smithsonian. “All publicly available images can now be made accessible. As with any good inclusive practice, this benefits a range of digital image users and producers. The foresight of the IPTC Photo Metadata Working Group is commendable.”
Web accessibility is mission-critical in our digitally inclusive age. As the number of images added to the web increases every day, the visual gap widens for people using assistive technologies, especially if they are blind. Embedding image descriptions for accessibility into photo metadata promises to be a game-changer, making it possible for software and systems to routinely provide alt text with images, thus giving screen reader software the ability to help readers visualise and listen to image descriptions as they are read out loud. Without accessible descriptions, images are silent for the millions who rely on screen readers to fully access the web.
As Richard Orme, CEO of the DAISY Consortium, has pointed out, “Up to 250 million people with blindness or moderate to severe vision impairment can benefit from image descriptions, plus countless more people with diverse information processing differences such as dyslexia who use text-to-speech technology for reading.”
The year 2020 was pivotal for web accessibility. Many disabled people were at high risk of severe illness from COVID-19 but struggled to access the essentials online — everything from healthcare and education to groceries and supplies. Inaccessible websites and applications have always been a barrier; during COVID, they became a threat to the health and safety of a vulnerable population.
Image descriptions are essential for people with visual impairments using assistive technologies and a fundamental requirement of the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines (WCAG), the most widely-used guidelines for web accessibility in the world (W3C Web Accessibility Laws and Policies).
IPTC’s new accessibility properties will make it easier for platforms and software to comply with WCAG requirements and deliver images that are inclusive for everyone. Embedding accessible image descriptions into the photo metadata will make it possible for alt text and extended descriptions to travel wherever the image goes on the web or in books or other documents provided as EPUBs.
If you are interested, there are a few things you can do now:
- Attend the IPTC Photo Metadata Conference on November 4th to understand more about the new properties and how you can use them.
- Contact your software providers to tell them about these new properties and emphasise that these features are very important to you. Ask them when they will make the new properties available in their user interface.
- Contact your web content management software provider to make that case as well.
- For larger enterprises, think about how you could implement these properties into your organisation’s workflow.
The online IPTC Photo Metadata Standard specification will be updated to the new version on 4 November 2021.
