To create a namespace in [[Roam Research]], name a page something like `category/title` where `category` is the namespace. This is a way to create a directory within Roam. This is particularly helpful in cases where naming a page `title` might be too ambiguous because there are more than one cases in which it might be used. This is also a fantastic way to separate fictional worlds within a single [[Zettelkasten]]. To toggle the category of the namespace on and off in links on a page, use `CTRL+C+L` until the category disappears and the link turns green. This indicates that the category or namespace is being hidden for brevity. Some use cases - `D&D/` for everything related to the [[Dungeons & Dragons]] campaign - `Article/` so that you can have, for example, an article someone else wrote called "Chaos engineering" and a note that you created with the same filename. -
