Use Case
The simplest viable manifest for audio content. This pattern presents a single audio file in a IIIF Presentation resource.
Implementation Notes
The implementation is identical to the image example, except that the content is audio and the canvas has the duration property instead of the height and width properties. The value of the duration property must be a positive number of seconds, such as 1985 or 1985.024.
Example
This example shows a Manifest with a single Canvas that lasts for 1985.024 seconds. It has a single audio file which is associated with it. The mp4 also has a duration of 1985.024 seconds.

Use Case
The simplest viable manifest for audio content. This pattern presents a single audio file in a IIIF Presentation resource.
Implementation Notes
This illustrates the mandatory structure and properties of a manifest, with the simplest possible audio content.
Audio resources are contained inside a Timeline, which is required to have a duration property with the time, in seconds, of the audio resource to be included in the timeline. The value of the duration property must be a positive number, such as 1985 or 1985.024.
The items property of the Canvas is a list of annotation pages. In this case there is only one. The items property of the annotation page is a list of annotations. Again, in this case there is only one. This annotation links the audio resource and the timeline. The body of the annotation is an audio file, the url of which is the id property of the body. The duration of the audio file, in seconds, is given and here matches the timeline’s duration property exactly. Matching is not required, but mismatches will change how much of the audio is heard and may change what happens after the audio finishes playing. The target property tells us both that the audio file is associated with the entirety of the container and that the container is a timeline, and the motivation property of “painting” tells us that the audio file is the content of the container.
The type of the resource is “Audio” but viewers should accept “Sound” as a synonym for Audio to improve compatibility with previous versions. For more details see the type definition.
Example
This example shows a Manifest with a single Timeline that lasts for 1985.024 seconds. It has a single audio file associated with it. The mp4 also has a duration of 1985.024 seconds.
