Photo Metadata Picker¶

Choose Media library, with nearby photographs as the widget for a media reference field. Below the usual media library it lists photographs within a radius of the content being edited, nearest first, each with a "Use this photo" button that adds it through the media library's own selection, so cardinality, access and validation all still apply.

The nearby list under a media field on a node form, ordered by distance from the node's location, each row with a "Use this photo" button.

Where content is¶

Worked out by origin sources, asked in priority order:

Priority	Source
300	A geofield on the entity being edited: the unsaved value in the form, then the saved one
100	A geofield on an entity it references (media references excluded)

The editor is always told which source answered. Add a source for content that is located some other way by implementing Drupal\photo_metadata_picker\Origin\OriginSourceInterface and tagging the service photo_metadata_origin with a priority.

Views¶

View	Path	For
Photo library	`/admin/content/media/photos`	Filter by name, keyword and whether a photo has coordinates; sort by date taken or credit. Its `proximity` display is what the widget embeds.
Photo map	`/admin/content/media/map`	Where photographs were taken. Installed only with Leaflet Views.
Photo metadata gaps	`/admin/content/media/photo-gaps`	Photographs missing coordinates, a date taken, a caption or keywords, as a worklist.

The widget's view is a setting, so a site can point it at its own. All three views are removed when the module is uninstalled.
