Every page in your space is available via the `page` tag. You can attach _additional_ tags to a page, by either specifying them in the `tags` attribute [[Frontmatter]], or by putting additional [[Tag|tags]] in a standalone paragraph with no other (textual) content in them.

In addition to `ref` and `tags`, the `page` tag defines a bunch of additional attributes as can be seen in this example query:

${query[[from index.tag "page" where name == _CTX.currentPage.name]]}
