[[Dataviewはノートのfrontmatterと本文からkeyが取得できる]]だけでなく、Dataviewはファイルの更新日やリンクなどからもkeyを取得できる。 **ファイル名に日付があると`file.day`が取得できる。**（yyyy-mm-dd or yyyymmdd） →[Data Annotation - Dataview](https://blacksmithgu.github.io/obsidian-dataview/data-annotation/) その他、以下のようなkeyを取得可能。 - file.day - `file.name`: The file title (a string). - `file.folder`: The path of the folder this file belongs to. - `file.path`: The full file path (a string). - `file.ext`: The extension of the file type; generally '.md' (a string). - `file.link`: A link to the file (a link). - `file.size`: The size (in bytes) of the file (a number). - `file.ctime`: The date that the file was created (a date + time). - `file.cday`: The date that the file was created (just a date). - `file.mtime`: The date that the file was last modified (a date + time). - `file.mday`: The date that the file was last modified (just a date). - `file.tags`: An array of all unique tags in the note. Subtags are broken down by each level, so `#Tag/1/A` will be stored in the array as `[#Tag, #Tag/1, #Tag/1/A]`. - `file.etags`: An array of all explicit tags in the note; unlike `file.tags`, does not include subtags. - `file.inlinks`: An array of all incoming links to this file. - `file.outlinks`: An array of all outgoing links from this file. - `file.aliases`: An array of all aliases for the note. - `file.tasks`: An array of all tasks (I.e., `- [ ] blah blah blah`) in this file. - `file.lists`: An array of all list elements in the file (including tasks); these elements are effectively tasks and can be rendered in task views. - `file.frontmatter`: Contains the raw values of all frontmatter; mainly useful for checking raw frontmatter values or for dynamically listing frontmatter keys. また、スタープラグインを使うとスターの有無からも取得できる。 ## テスト 構文：'file.name: \`= this.file.name\`' 結果：file.name: `= this.file.name` 構文：file.folder: \`= this.file.folder\` 結果：file.folder: `= this.file.folder` 構文：file.path: \`= this.file.path\`. 結果：file.path: `= this.file.path`. 構文：file.ext: \`= this.file.ext\` 結果：file.ext: `= this.file.ext` 構文：file.link: \`= this.file.link\` 結果：file.link: `= this.file.link`. 構文：file.frontmatter: \`= this.file.frontmatter\` 結果：file.frontmatter: `= this.file.frontmatter`.
