AS関連データの取り扱いを簡単にすることを目的に書き出した、privateDatatypeLibです。
プログラムとデータを分離して、データ記述部分を外部ファイル（設定ファイルなど）に追い出したときに、どのようなデータかを表現するための道具として試作してみました。
macOS上のデータ記述子は、
などのさまざまなデータ識別方法が存在していますが、どれも（自分の）用途には合わなかったので、検討・試作をはじめてみました。Predicatesが一番近いものの、不十分なのでいろんなデータ型や用途に拡張。あくまで自分用なので「public」などの宣言はとくに不必要と考え、縮小して処理を行なっています。
とくに、ファイルパスの処理なんて定型処理しかしないのに、わざわざ何かの表現を行う必要があるのはナンセンスですし、日付関連も割と余計な記述が多いように感じています。
また、緯度/経度のデータや座標データなども、もう少しなんとかならないかと思っています。
