Commonplace Book is a multi-user wiki implemented as a single page application using Svelte. CPB is a work in progress but currently functions admirably as a basic wiki.

Design Concepts

Resources

All objects in the wiki are modeled as resources, from users to images to articles, and all resources are treated uniformly. Resources are addressed by an NSTU and may be anchored in the global namespace. All resources have a UUID by which they can be addressed regardless of their location in the namespace, if any. All resources are versioned and old versions may be addressed by their UUID.

NSTU

An NSTU is an identifier which can be used to address resources in CPB. NSTU stands for Namespace-Title/UUID. All resources always have a UUID by which they may be addressed. Resources anchored to the namespace by also be addressed by their namespace and title. Examples of valid NSTUs:

• Home (The resource anchored at main:Home. The main namespace may be omitted.)
• main:Home (Same as above.)
• docs:Editing (Namespaces other than main have to be given explicitly.)
• :login (There exists a special blank namespace used for system pages, like the login page.)
• docs: (Every namespace has an index page at its root.)
• BD1B6976-3007-48AF-99DD-DF069B0306EC (Every resource and version has a UUID by which it may be addressed. UUIDs are valid NSTUs.)
• ~root (User resources are unique in that their title must always begin with a tilde. No other resource may beginw with one.)

Namespace

Resources can be anchored to a namespace by giving them a title. They can then be addressed by their Namespace-Title pair (the NST in NSTU). The default namespace is called main and may be omitted in NSTUs.

Wiki Markdown

CPB features a purpose-built markup language called Wiki Markdown, or WMD. WMD combines Markdown with WikiText link syntax and features novel syntax for decorators and external link shortcuts.
