Explanation

Code 45 is used to indicate that images in the publication contain text content.

Text in images is where the text is separate from the image data so can be accessed by assistive technologies or restyled to meet user preferences. SVG is the most common example of an image format that allows text to be retained in the image (e.g., through the <text> element).

Note that in many image formats, like JPEG and PNG, any text is just part of the image data and cannot be accessed or modified. Use code 49 for this case.

Code 45 is typically set in a <ProductContentType> element for digital publications. Publications whose primary content is text in images are rare.

Only for use in ONIX 3.0 or later.

Schema.org mapping

Code 45 is the equivalent of setting a textual access mode using schema.org metadata.
