- Tiddlyweb is a key-value store.
- A bag is a namespace. Permissions are defined on bags and apply to all key-value pairs within.
- A tiddler is a (Key, Value) pair, where the title of the tiddler is the key, and the remaining parts of the tiddler are the value part. Tiddler values have a set structure in order to ensure that metadata is stored in a uniform way (tags,fields,text).
