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

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

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