The quarto documentation explains how to use metadata within the document, and also how to access nested values using the dot notation: https://quarto.org/docs/authoring/variables.html. However, it doesn't explain how to access array/list elements, and indeed I can't find a syntax that supports this.
In the following document I show my attempts to do this:
---
top: "Top Lvel"
nested:
str: "Nested String"
array:
- foo
- bar
---
{{< meta top >}}
{{< meta nested.str >}}
{{< meta nested.array[0] >}}
{{< meta nested.array[1] >}}
{{< meta nested.array.0 >}}
{{< meta nested.array.1 >}}
This renders to PDF like this, showing that none of my attempted array accesses worked:
