<ul>
<li>owl:NamedIndividual is used as a declaration. As such, it does not affect reasoning and serves only to check that a particular entity is used in accordance with how it was declared. This is not important much when you use the RDF-based semantics (and in OWL 2 Full, it is the same class as owl:Thing), but OWL 2 DL distinguishes between named (using IRI) and anonymous (using bNode) individuals, and some profiles of it even disallow anonymous individuals completely.</li>
<li>Protegé here does its best to ensure that the ontology is acceptable in the various lower profiles, by marking declarations based on the way they are identified, but it is not strictly an error if you do something like _:bnode a owl:NamedIndividual . ‒ you may use that to convey that it really is a proper individual that has an (unknown) IRI, as opposed to an existential quantifier-like notion used by RDFS.</li>

Welcome! And beware!  

## Purpose

This vault is the "[[learning-in-public|ar.swyx.learn-in-public]]" part of my Second Brain. If you share some of my interests, please [reach out](https://djradon.github.io)! 

## Contents

- [[t]] my personal wikipedia
- [[idea]] (not necessarily mine)
- Resource Notes, including highlights, thoughts and metadata, for various things:
  - [[ar]] mostly articles, papers and web pages
  - [[book]]
  - [[community]]
  - [[course]]
  - [[event]]
  - [[game]]
  - [[loc]]
  - [[org]]
  - [[user]] 
  - [[prdct]] mostly software products, but also ontologies
  - [[recipe]]
  - [[video]] movies, tv episodes, youtube, etc
- [[vs]]
- [[wanted]]
- Some "Metadata Notes":
  - [[tags]] which may refer to any and multiple (or none) of the above
  - [[c]]: ways to categorize resources
  - [[p]]: ways to assert things about resources (mostly abandoned)

In terms of the [[t.km.zettelkasten]] method, this wiki is a commingling of literature notes with something @Sönke-Ahrens warned about: a "personal Wikipedia or a database" [^1]. 

In terms of [[t.tm.getting-things-done]], it's references, someday-maybe, next actions, and public projects.

## Beware!

This is a cluttered cupboard of jumbled jottings riddled with inaccuracies, confusion, and mistakes.

## What This Is Not

- evergreen-notes/digital-garden: for "synthesized" / original-ish publishable big-idea notes that should evolve over time, props to @andy-matuschak and @maggie-appleton
- blog: for "point-in-time" items to be shared: personal news, articles, etc.
  - e.g., [[ar.substack.carpe-noctem]]
