我不知道一个完整的YAML实现，但 JSON （一个子集）越来越流行，甚至还有一些在JSON站点上列出的Delphi库。 Delphi 2009甚至在DataSnap中使用（稍微修改版本的）JSON。

I don't know about a full YAML implementation, but JSON (a subset) is getting pretty popular and there are even some Delphi libraries listed on the JSON site. Delphi 2009 is even using (a slightly modified version of?) JSON in DataSnap.
