OLAC Best Practice for accessibility content

Apply the option for videodiscs, streaming video and objects when readily available.

Provide a free text note to record details when known, such as: tactile assistive features on objects (e.g. braille on the container); when accessibility content applies to only a portion of the resource (e.g., closed captions for a video that appears for the main feature, but not the bonus content); if special equipment is required to access accessibility content; or if a container indicates accessibility content that is not present in the resource. For sign language in a video, provide specific information if known, such as the nature of the sign language included in the resource; the sign system (e.g. American Sign Language, British Sign Language); how much of the content is signed and if signing is the sole medium of communication, or if it is used in conjunction with other mediums. For streaming media, follow PCC Provider-Neutral E-Resource MARC Record Guidelines. Record the name of the provider that this information applies to. Record only accessibility content that is specific to the resource and not features that are generated on the fly. (For the language of accessibility content, such as the language of captions, see Expression: language of expression).

Record the assistive features of the content using a controlled vocabulary such as Schema.org Accessibility Properties for Discoverability Vocabulary (SAPDV) (see the accessibilityFeature property). For streaming media, follow PCC Provider-Neutral E-Resource MARC Record Guidelines. Record the name of the provider that this statement applies to. Record only accessibility content that is specific to the resource, and not features that are generated on-the fly. (For the language of accessibility content, such as the language of captions, see Expression: language of expression.)

Include the code for the vocabulary used from the LC Accessibility Content Source Codes .
