# abstract-to-meta
This moves a document's abstract from the main text into the
metadata. Metadata elements usually allow for finer placement
control in the final output, but writing body text is easier and
more natural.
## Defining an Abstract
A document abstract can either be put directly in the document
metadata, for example by inserting an *abstract* attribute into a
YAML block.
---
abstract: |
Place abstract here.
Multiple paragraphs are possible.
---
The additional indentation and formatting requirements in YAML
headers can be confusing or annoying for authors. It is hence
preferable to allow abstracts be written as normal sections.
# Abstract
Place abstract here.
Multiple paragraphs are possible.
This filter turns the latter into the former by looking for a
top-level header whose ID is `abstract`. Pandoc auto-creates IDs
based on header contents, so a header titled *Abstract* will
satisfy this condition.^[1]
[1]: This requires the `auto_identifier` extension. It is
enabled by default.
