building SMART のCTO、解任されてたんですね……
「2025年10月までに、CAD/BIMの状況は劇的に変化した」
linkedin.com/posts/boikoarte…
【訳】
① Autodesk、Nvidia、Apple、Adobe が USD（Universal Scene Description）を推進するための AOUSDアライアンス を結成。 そして突然、Autodeskと共にbuildingSMARTを創設した HOK までもが USD を推進し始めた。
② しかし 2025年9月 に、主要ベンダーが突如として IFC5の開発を大幅に減速。 開発はほぼ停止状態（複数の情報筋より）。
③ 2週間前、7年間にわたり IDS・IFC・BCF・API を牽引してきた buildingSMART のCTO が突然解任。
④ 2025年半ばまでに、Oracle が buildingSMART における OpenCDEトピックをほぼ独占。
⑤ ほぼすべてのopenBIMアプリケーション（Bonsai、BlenderBIM、IfcOpenShell など）の基盤である OpenCascadeチーム が分裂。 一部はポルトガルへ移り、他のメンバーは 中国で新しいOSSコアを開発 し始めた。

IfcOpenShell の理解深まって面白い。使い方勘違いしてたところあるのでそこ理解できたの良い。
それでもこのcpp のお化けコード、パフォーマンス的に問題色々ありそうだなとも感じた。取り敢えず自分でコンパイルして zig から遊んでみるかな。
それとifcToSql あるの初めてしった。戯れてみる。

ifcopenshellで遊んでいたらこんなものを見つけた。標準化TFで標準属性項目リストとか作られていたんだな。これらのパラメータを取得できるようにifcopenshellで頑張ってみるか。
それにしても設備のパラメータ数多すぎ。
