Thereby gallery keys are mapped to data keys, i.e., column names of the data layers.

In the following, the keys are divided thematically via sections, where each section groups specific functionalities in the gallery.

Main gallery | ||||
mime_type | The MIME-Type used to distinguish between media in the gallery. It is based on the source media, not the web preview file (e.g, video/mp4). Consequently, it starts with 'image' or 'video' (e.g., image/jpg, video/octet-stream). Capitalization does not matter. If not available, auto guessing based on acquisition - if defined, else based on presence of photo_src and video_src. | |||
photo_src | URL to the web version of the photo file. Fallback if scrset is not given or not supported by the browser. | |||
photo_srcset | HTML5 img srcset attribute. Recommended to use width descriptor. | |||
video_src | String or list with strings containing URLs to media representations. Recommended to use a list for streams, where each list item is a fallback if the previous item was not supported in the browser. Example: [ | |||
photo_width | Largest width of photo proxy. Observe: if an orientation parameter is present in the exif metadata of the a proxy, it will not be considered. Consequently, the photo_width must be larger than the photo_height to show the a proxy in landscape mode. | |||
photo_height | Largest height of photo proxy. Observe: if an orientation parameter is present in the exif metadata of the a proxy, it will not be considered. Consequently, the photo_width must be smaller than the photo_height to show the a proxy in portrait mode. | |||
video_width | Largest width of video proxy (same orientation as proxy). | |||
video_height | Largest height of video proxy (same orientation as proxy). | |||
thumbnail_src | URL to the webvtt file. Thumbnails are shown when pointer hovers over video player seek bar. | |||
cover_src | URL to the video cover. | |||
cover_srcset | HTML5 img srcset attribute. Recommended to use width descriptor. | |||
poster_src | Background poster when loading video in player. If skipped, default viewer based posters are shown. | |||
duration | Video duration in human readable format, i.e., 00:16:45. Shown as overlay on video cover. | |||
Sharing Feature | ||||
persistent_identifier | Media identifier used for the sharing feature in the media gallery. Fallbacks exist when not given. | |||
name | File name of the source media file. Assumption: Only once per gallery. Sharing feature: First fallback if no persistent identifier is given. | |||
date_time | Sharing feature: Second fallback if no persistent identifier is given to calculate a share id (together with coordinates). |
