Lightroom カタログを解析して欲しい情報を取り出す

Last updated at Posted at 2022-03-15

intro

古いLightroomをずっと使っていたが、そろそろ、いよいよの時に備えて中の情報を引っ張り出せるようにしておこうと、ちょっと調査。

私の場合は、フィルムカメラの写真に対して、カメラ、レンズ、フィルムなどの情報をキーワードで持たせていたので、これはサルベージしておかなないとなにがなんだかわからなくなる。また、そこそこイケてる写真だけ旗つけて、星の数で成績つけて、普段はそれらだけみていたので、その辺の情報も抜いておける必要がある。
EXIF関係はどうせ画像から取れるので、今は気にしない。

テーブル構造

Lightroomのカタログファイルlrcatは、実はただのSQLiteファイルなのでSQLiteコマンドでいくらでも中は確認できる。
構造把握を目的に、ファイルを3つだけ登録したカタログを作ってSQLiteコマンドで中を見てみた。

とりあえず、.tablesコマンドでSQLiteの場合はテーブル一覧が取れる。

$ sqlite3 lr_exp/lr_exp.lrcat
SQLite version 3.24.0 2018-06-04 14:10:15
Enter ".help" for usage hints.

ぱっと見、大量にあるが、重要なのは以下のもの

Adobe_images: 画像の管理情報本体
AgLibraryFile: 画像に対するファイル情報(ファイル名、拡張子など)
AgLibraryFolder: ファイルのディレクトリネーム部（ある起点からの相対パス）
AgLibraryRootFolder: 起点のフルパス
AgLibraryKeyword: キーワード
AgLibraryKeywordImage: キーワードと画像を対応づけるピボットテーブル

.schemaコマンドとselectで中の構造を見てみる。

カラーラベルが何故か文字列でそのまま入っている（colorLabels）。
pickとratingがそれぞれ旗と星。
rootFileがちょっとわかりにくいが、これがAgLibraryFileのid_localで、これで連結できる。

ファイル名（basename）が入っている。そのほか拡張子やらsidecarやらいろいろあるが、今は不要。
folderがAgLibraryFolderのid_localのはず。

AgLibraryFolder

sqlite> .schema AgLibraryFolder
CREATE TABLE AgLibraryFolder (
    id_local INTEGER PRIMARY KEY,
    id_global UNIQUE NOT NULL,
    pathFromRoot NOT NULL DEFAULT '',

こちらは、使われないものも含めてディレクトリ（Lightroomの都合で年月日）を様々持っている。
rootFolderがAgLibraryRootFolderのid_local。

AgLibraryRootFolder

sqlite> .schema AgLibraryRootFolder
CREATE TABLE AgLibraryRootFolder (
    id_local INTEGER PRIMARY KEY,
    id_global UNIQUE NOT NULL,
    absolutePath UNIQUE NOT NULL DEFAULT '',
    name NOT NULL DEFAULT '',
    relativePathFromCatalog
);
sqlite> select * from AgLibraryRootFolder;
29|6693A5CB-A878-4814-A67B-1CABA4F28068|/Users/makainuma/Pictures/|Pictures|../../../Pictures/

こちらは、フォルダパスの起点のフルパス。

以上、joinすれば以下のようになる。

   ...> AgLibraryFolder.pathFromRoot,

大文字小文字の表記ゆれ対策でlc_nameとnameと二つ持っていることがわかる。
これは、ではどうやって画像と紐づけているのかというと次。

AgLibraryKeywordImage

sqlite> .schema AgLibraryKeywordImage
CREATE TABLE AgLibraryKeywordImage (
    id_local INTEGER PRIMARY KEY,
    image INTEGER NOT NULL DEFAULT 0,
    tag INTEGER NOT NULL DEFAULT 0
);
CREATE INDEX index_AgLibraryKeywordImage_tag ON AgLibraryKeywordImage( tag );
CREATE INDEX index_AgLibraryKeywordImage_image ON AgLibraryKeywordImage( image );
sqlite> select * from AgLibraryKeywordImage;
222|72|221
224|72|220
226|72|219

imageが画像の方のid_localでtagがAgLibraryKeywordのAgLibraryKeyword。

画像とキーワードが多対多の関係で、本来なら右にOUTER JOINしたいところだが、

RIGHT and FULL OUTER JOINs are not currently supported

と言われてしまうので、諦めてLEFT OUTER JOINしてみる。

sqlite> SELECT Adobe_images.id_local, AgLibraryKeyword.name
   ...> from Adobe_images
   ...> LEFT OUTER JOIN AgLibraryKeywordImage ON Adobe_images.id_local = AgLibraryKeywordImage.image
   ...> INNER JOIN AgLibraryKeyword ON AgLibraryKeywordImage.tag = AgLibraryKeyword.id_local;

悪魔の発明group_concat()を使って

sqlite> SELECT
   ...> AgLibraryFolder.pathFromRoot,
   ...> AgLibraryFile.originalFilename,
   ...> group_concat(AgLibraryKeyword.name)
   ...> from Adobe_images
   ...> LEFT OUTER JOIN AgLibraryKeywordImage ON Adobe_images.id_local = AgLibraryKeywordImage.image
   ...> INNER JOIN AgLibraryKeyword ON AgLibraryKeywordImage.tag = AgLibraryKeyword.id_local
   ...> INNER JOIN AgLibraryFile ON Adobe_images.rootFile = AgLibraryFile.id_local
   ...> INNER JOIN AgLibraryFolder ON AgLibraryFile.folder = AgLibraryFolder.id_local
   ...> GROUP BY Adobe_images.id_local;

ま、こんなもんでしょう

追加

キーワードに対して、それがつけられている画像一覧（id_local）

SELECT
AgLibraryKeywordImage.tag,AgLibraryKeyword.name,group_concat(AgLibraryKeywordImage.image)
from AgLibraryKeywordImage
INNER JOIN AgLibraryKeyword ON AgLibraryKeywordImage.tag = AgLibraryKeyword.id_local
GROUP BY AgLibraryKeywordImage.tag;

画像idとファイル名の対応

SELECT Adobe_images.id_local,
AgLibraryFolder.pathFromRoot,
AgLibraryFile.originalFilename
FROM Adobe_images 
INNER JOIN AgLibraryFile ON Adobe_images.rootFile = AgLibraryFile.id_local
INNER JOIN AgLibraryFolder ON AgLibraryFile.folder = AgLibraryFolder.id_local;

キーワードに対するファイル名の一覧

sqlite> SELECT
   ...> AgLibraryKeywordImage.tag,AgLibraryKeyword.name,AgLibraryKeywordImage.image,
   ...> group_concat(AgLibraryFolder.pathFromRoot || AgLibraryFile.originalFilename)
   ...> from AgLibraryKeywordImage
   ...> INNER JOIN AgLibraryKeyword ON AgLibraryKeywordImage.tag = AgLibraryKeyword.id_local

コレクションセットの階層構造をSQLで再現するのは難しそうなので一旦諦めて、
コレクション名とファイル名の連結だけやってみる

sqlite> SELECT AgLibraryCollection.name,
   ...> AgLibraryFile.originalFilename
   ...> FROM AgLibraryCollectionImage
   ...> INNER JOIN AgLibraryCollection ON AgLibraryCollectionImage.collection = AgLibraryCollection.id_local 
   ...> INNER JOIN Adobe_images ON AgLibraryCollectionImage.image = Adobe_images.id_local
   ...> INNER JOIN AgLibraryFile ON Adobe_images.rootFile = AgLibraryFile.id_local
   ...> INNER JOIN AgLibraryFolder ON AgLibraryFile.folder = AgLibraryFolder.id_local
   ...> ORDER BY AgLibraryCollection.name;
