A zettel representation that is a [[s-expression|00001012930000]] (also known as symbolic expression).

It is (relatively) easy to parse and contain all relevant information of a zettel, metadata and content.
For example, take a look at the Sz encoding of this page, which is available via the ""Info"" sub-page of this zettel:
* [[//z/00001012920516?enc=sz&part=zettel]],
* [[//z/00001012920516?enc=sz&part=meta]],
* [[//z/00001012920516?enc=sz&part=content]].
Some zettel describe the [[Sz encoding|00001012931000]] in a more detailed way.

If transferred via HTTP, the content type will be ''text/plain''.
