# data: Data files

## Fields

* [aliases](../fields/aliases.md): Relative paths in the destination directory where the page should also show up.
[Like in Hugo](https://gohugo.io/extras/aliases/), this can be used to maintain
existing links when moving a page to a different location.
* [asset](../fields/asset.md): If set to True for a file (for example, by a `file:` pattern in a directory
index), the file is loaded as a static asset, regardless of whether a feature
would load it.
* [author](../fields/author.md): A string with the name of the author for this page.
* [copyright](../fields/copyright.md): Copyright notice for the page. If missing, it's generated using
`template_copyright`.
* [data_type](../fields/data_type.md): Type of data for this file.
* [date](../fields/date.md): Publication date for the page.
* [description](../fields/description.md): The page description. If omitted, the page will have no description.
* [draft](../fields/draft.md): If true, the page is still a draft and will not appear in the destination site,
unless draft mode is enabled.
* [image](../fields/image.md): Image used for this post.
* [indexed](../fields/indexed.md): If true, the page appears in [directory indices](dir.md) and in
[page filter results](page_filter.md).
* [links](../fields/links.md): Extra metadata for external links.
* [nav](../fields/nav.md): List of page paths, relative to the page defining the nav element, that
are used for the navbar.
* [nav_title](../fields/nav_title.md): Title to use when this page is linked in a navbar.
* [pages](../fields/pages.md): The `pages` metadata can use to select a set of pages shown by the current
page. Although default `page.html` template will not do anything with them,
other page templates, like `blog.html`, use this to select the pages to show.
* [related](../fields/related.md): Readonly mapping of pages related to this page, indexed by name.
* [series](../fields/series.md): List of categories for the `series` taxonomy.
* [series_title](../fields/series_title.md): Series title from this page onwards.
* [site_name](../fields/site_name.md): Name of the site. If missing, it defaults to the title of the toplevel index
page. If missing, it defaults to the name of the content directory.
* [site_url](../fields/site_url.md): Base URL for the site, used to generate an absolute URL to the page.
* [syndicated](../fields/syndicated.md): Set to true if the page can be included in a syndication, else to false.
* [syndication](../fields/syndication.md): Defines syndication for the contents of this page.
* [syndication_date](../fields/syndication_date.md): Syndication date for this page.
* [tags](../fields/tags.md): List of categories for the `tags` taxonomy.
* [template](../fields/template.md): Template used to render the page. Defaults to `page.html`, although specific
pages of some features can default to other template names.
* [template_copyright](../fields/template_copyright.md): jinja2 template to use to generate `copyright` when it is not explicitly set.
* [template_description](../fields/template_description.md): jinja2 template to use to generate `description` when it is not
explicitly set.
* [template_title](../fields/template_title.md): jinja2 template to use to generate `title` when it is not explicitly set.
* [title](../fields/title.md): Page title.

## Documentation

Data files have a `.json`, `.yaml`, or `.toml` extension and can be rendered
with custom Jinja2 templates.

The content of the data file is parsed, and merged into the page metadata.

The jinja2 template can be chosen using the `data_type` metadata field.

The metadata of any page with the `data_type` metadata will be also tracked as
data. This allows to create normal pages that also add to a named dataset.
