Create a file with the .base extension containing valid YAML. Define filters to select notes, optionally add formulas for computed properties, then configure one or more views (table, cards, list, or map) with an order list of properties to display.

Use the filters key with a single expression string or nested and/or/not objects, such as 'status == "done"' or file.hasTag("book"). Global filters apply to all views, while view-level filters narrow results for that specific view.

Bases supports table, cards, list, and map view types. Table, cards, and list work with standard note and file properties, while the map view requires latitude and longitude properties plus the Maps community plugin.

Subtracting two dates returns a Duration type, not a number, so you cannot call .round() on it directly. Access a numeric field first, like (now() - file.ctime).days, then apply number functions such as .round(0).

Common causes are unquoted strings containing special characters like colons, and double quotes nested inside double-quoted formulas. Wrap formulas containing double quotes in single quotes, and quote display names containing special characters.

Yes, embed a base in Markdown with ![[MyBase.base]], or target a specific view with ![[MyBase.base#View Name]]. The this keyword refers to the embedding file when the base is embedded.
