GNOME Photo Companion (gnome-photo-companion) =E2=80=94 Design Document and
Prototype in C/Meson1. Purpose
GNOME Photo Companion (working ID: gnome-photo-companion) is a standalone
GTK4/Libadwaita application that complements *GNOME Photos* with two
features Photos doesn't cover well today:
1. *Photo Location Map* =E2=80=94 plot geotagged photos on an
OpenStreetMap-based map, using EXIF GPS tags.
2. *EXIF Search* =E2=80=94 fast, indexed search over EXIF/IPTC metadata =
(camera,
lens, date, GPS presence, focal length, ISO, etc.) across a photo librar=
y.
Storage is *local-only* for this iteration: the library root is
~/Pictures (XDG_PICTURES_DIR),
with no cloud backend. The architecture reserves a clean seam for a cloud
provider later (GNOME Online Accounts / WebDAV), but nothing cloud-related
ships in v0.
It is designed to sit next to the existing GNU Photo work (the gphoto C
dispatcher bridging libgphoto2 and gnome-photos): Companion doesn't talk to
cameras directly, it indexes whatever lands in ~/Pictures (including files
gphotohas already downloaded there).
2. Non-goals (v0)
- No image editing.
- No cloud sync/backend (Nextcloud, GOA, etc.) =E2=80=94 reserved for a =
later
phase.
- No camera/device access =E2=80=94 that's gphoto's job.
- Not a GNOME Photos plugin/extension; it's a companion app that reads
the same photo library and can hand off "open in Photos" via
GAppLaunchContext.
3. High-level architecture

Components
Component Responsibility
GpcApplication AdwApplication subclass; owns the single GpcPhotoStore +
GpcExifIndex.
GpcWindow AdwApplicationWindow; hosts AdwViewStack with two views: *Grid*
and *Map*. Search bar filters both.
GpcPhotoStore Walks ~/Pictures recursively (async, GFile/GFileEnumerator),
watches for changes with GFileMonitor, emits photo-added/photo-removed.
GpcExifIndex On photo-added, extracts EXIF/IPTC/XMP via *gexiv2* and
upserts a row into a local *SQLite* cache (~/.cache/photo-companion/exif.db=
).
Exposes async search queries (GpcExifQuery).
GpcMapView Wraps *libshumate* (ShumateMap + ShumateMarkerLayer), OSM raster
tile source (shumate_map_source_registry default OSM entry). Subscribes to
index query results and drops one marker per GPS-tagged photo; clicking a
marker selects it in the grid.
GpcSearchQuery Small struct/GObject describing a parsed search (free text +
structured filters like camera:, lens:, has-gps:true, date>=3D). Parsed fro=
m
the search entry text.
Data flow
1. GpcPhotoStore enumerates ~/Pictures, filtered by MIME type (image/jpe=
g
, image/tiff, image/png, common raw types).
2. Each discovered file is queued to GpcExifIndex, which runs
gexiv2 extraction
on a worker thread (GTask), then writes to SQLite.
3. GpcWindow's search entry produces a GpcSearchQuery; both the grid
view and GpcMapView re-run the query against GpcExifIndex and re-render.
4. GFileMonitor events keep the index (and therefore both views) live as
photos are added/removed/edited on disk =E2=80=94 e.g. right after gphot=
o downloads
new images.
4. EXIF search =E2=80=94 supported filters (v0)
Free text matches filename + camera make/model. Structured tokens:
- camera:"Canon EOS R5"
- lens:"RF 24-70mm"
- iso:>=3D800
- date:2025-06-01..2025-06-30
- has-gps:true / has-gps:false
- orientation:portrait|landscape
These map to a WHERE clause built against indexed columns (camera_make,
camera_model, lens, iso, taken_at, gps_lat, gps_lon, width, height).
5. Map view
- Library: *libshumate* (the GTK4 map widget used by GNOME Maps), giving
GTK4-native OSM rendering, clustering, and marker layers for free.
- Tile source: default OpenStreetMap raster source from
shumate_map_source_registry_new_with_defaults()=E2=80=94 respects OSM ti=
le usage
policy, no API key required for v0.
- Marker clustering (ShumateMapMarker grouping) recommended once library
size grows, deferred to v1.
- Clicking a marker calls gpc_window_select_photo(), syncing the grid's
selection and opening a detail popover with a "Open in Photos" button (
g_app_info_launch_default_for_uri scoped to org.gnome.Photos).
6. Storage layout
~/Pictures/ # library root (XDG_PICTURES_DIR)
~/.cache/photo-companion/exif.db # SQLite EXIF index (rebuildable cache)
~/.config/photo-companion/ # GSettings-backed prefs (schema below)
The index is a *cache*, not a source of truth =E2=80=94 it can always be
regenerated by re-scanning ~/Pictures. This matters for the future cloud
phase: a cloud backend would just become a second GpcPhotoSource implementa=
tion
feeding the same GpcExifIndex.
7. Reserved seam for cloud storage (not built now)
To avoid a rewrite later, GpcPhotoStore should be defined against a small
GpcPhotoSource interface (GListModel-based) with GpcLocalPhotoSource as the
only implementation in v0. A future GpcCloudPhotoSource (GOA- or
WebDAV-backed) would implement the same interface. *Not implemented in this
pass* =E2=80=94 noted here only so the local-only code doesn't need to be
restructured later.
8. Dependencies
Library Purpose
gtk4 (>=3D 4.14) UI toolkit
libadwaita (>=3D 1.5) GNOME HIG widgets
libshumate (>=3D 1.2) OSM map widget
gexiv2 EXIF/IPTC/XMP extraction
sqlite3 EXIF index cache
glib/gio Core, async I/O, file monitoring
Build system: *Meson*, matching standard GNOME project conventions (and the
gphoto dispatcher's own build).

10. Roadmap
- *v0 (this pass)*: local scan of ~/Pictures, EXIF index + search, OSM
map view, grid view, live file monitoring.
- *v1*: marker clustering, thumbnail caching (via gnome-desktop-thumbnai=
l),
saved searches, GNOME Photos hand-off polish.
- *v2*: GpcCloudPhotoSource (GOA-backed), background sync, conflict
handling for duplicate GPS/EXIF edits.
10. Prototype
- *v0: *
