At the bottom of the Edit page for each node, there is a field for "URL Alias". While you can link to a node using the node ID and syntax like "www.oist.jp/node/123", the URL alias enables you to set another URL from which you can access the node.

The default setting for nodes is that the system create the URL alias by removing the punctuation and replacing spaces with hyphens in the title.

In order to keep the PRP library consistent, we must manually maintain the URL alias of each book page according to the following pattern: "policy-library/1.2.3", so that even if the title of the node is "Chapter 0 Principles and Fundamental Ideas", the URL Alias will be "policy-library/0", etc..

When making internal links (links from one part of the PRP to another), use the syntax "internal:policy-library/1.2.3" for English and "internal:ja/policy-library/1.2.3" for Japanese.
