Lexicons
A lexicon is the agreed shape of a record. These are the shapes a bullet, a note, and an outline are written in.
Why a record has a published shape
Anything on the network can read your repository, but reading is only useful if the reader knows what the fields mean. A lexicon is that description, published as a record itself, so another program can understand a Bulleted bullet without asking Bulleted anything.
It is also what makes the permission on the previous page meaningful.
Granting access to app.bulleted.node is a narrow
grant precisely because that name refers to a published, fixed shape.
The record types Bulleted defines
A node is one bullet. A note is the longer body attached to one. An outline carries a title, a description, and the preview image for a shared link. The rest exist for features that are still arriving.

Reading them yourself
Lexicon Garden is a browser for lexicons published on the network. You can look up any of the names above and read the actual schema — every field, which are required, and what the limits are — without installing anything.
Bulleted's own lexicons are published to the network the same way everything else is, which means they can be read, validated against, and built on by software that has nothing to do with this application.
