The media file should be made available via a persistent URL. If a link cannot be provided, an alternative delivery method for the media file should be agreed with portals or other data recipients.
If different images, videos, etc. are available, several media files may be provided. In this case, the file with the best available quality should be selected. If necessary, additional media files for subtitles, audio description and transcription can be provided for reasons of digital accessibility of audio and video files.
CARE: Sensitive items, such as religious or ritual artefacts, that are not appropriate for viewing or should be reserved for a specific group of people, may not be published with an image. A placeholder image may be used instead (see expressions in LIDO). Institutions should consult with people from the communities of origin. Ideally, ethical considerations should be documented in the database.
