Resource Registry
Resource 和 Bundle 註冊在 Products.CMFPlone/profiles/dependencies/registry.xml 檔案裡，預設 Bundle 共有 plone, plone-logged-in, plone-legacy, resourceregistry 但只有前三個是 Enabled 狀態，第二個 merge_with 選項是 logged-in，其他是 default。初期的擴充介面並不穩定。
example: Dict Field with Multiple Field Values
由於 JavaScript 生態系的相依關係日益複雜，演化出 Asynchronous Module Definition (AMD) API 之類的方案，新生代的開發工作，常結合 Bower, Grunt, RequireJS, Less 等工具，為了讓 Plone 能直接引用這些成果，藉由 Resource Registry 新機制，讓 Plone5 可以透過網頁介面簡化 RequireJS 和 LESS 的開發，但學習上需要先認識基礎觀念。
RequireJS 是符合 AMD API 的一項，
DataTables behaves differently if it's loaded when RequireJS is present (as it is in Plone5) than when t is not.
AMD or No AMD? Resource Registry aimed to provide a TTW way to define javascript modules and do dependency management

For legacy resources, define and require are unset before inclusion and re-set afterwards.
