TimeDrawer に、Mail.app の振り分けルールのような「ルール」を実装。現在テスト中。オブジェクトコントローラの使い方とか、正しい（正答）かどうかわからないのですが、とにかくバインディングとNSPredicateで結構簡単にできました。

Spotlight ( mdimport )がファイルの更新を監視しているのはこの機構を使用していると思われる。10.5 では一般向けのAPI が実装される模様。

Vector, Mac用のアプリケーション紹介用サイトとしては既に死んでいます。登録に１ヶ月必要という、なんともな仕様。そんなサイトで、JPO mdimporter がMacビジネス部門第３位でした。多分ダウンロードした人の99%はウインドウズ用のソフトウェアだと思っているはず。

Get kMDItemTextContent Value

Tue, 14 Aug 2007 20:53:31 +1200

You cannot retrieve kMDItemTextContent value from Spotlight query result.

Using these method below, mdimporter plugins can be used as viewer plugins for all the documents that the plugins support.
