Term Index

このページは PCE 2.0 の用語索引です。 Glossary が「短い説明を読むページ」だとすると、こちらは 知りたい語から、どのページを開けばよいかを逆引きするページ です。

使い分けは次のように考えるとよいです。

まず意味を短く知りたい → Glossary

ある語がどこで定義され、どこに関連しているかを引きたい → この Term Index

原則として、各項目の最初のリンクを canonical home とし、その後ろに関連ページを並べます。

使い方

1. まず canonical term を引く

たとえば Process Frame、Approval Points、Corrupt Success のように、ページ名と同じ語を知っているなら、まず下の Canonical Term Index を引くのが早いです。

2. 別名や外部語彙から引く

workflow、agent、merge、state、review のような語から入りたいなら、下の Alias / Lookup Index を使ってください。

3. どこから読めばよいか迷うなら

用語を引くより、導線から入った方が早いこともあります。その場合は Reading Paths を先に開いてください。

暫定的なまとめ

このページが言いたいことは、最終的には次の一文に集約できます。

PCE 2.0 の語彙は、用語の数が多いこと自体に価値があるのではない。何を current truth として採用してよいか、誰が何を retain し、何を delegate し、どこで止め、どこで戻し、どこで memory にするのかを、混同せずに言い分けるために必要なのである。

この Term Index は、その言い分けを素早く引き直すための入口です。
