Mentioning people, proper quoting, and linking to sources are the foundational features of this site. I am trying to be diligent with citations.

Therefore, I organize all external informational connections in groups:

1. Citation, mentioning:
   1. Names of people mentioned;
   2. Passages from publications, quotations.
2. Link:
   
   1. Sources of information;
   2. Titles of publications containing the facts;
   3. Origination of definitions and standards.

I also often provide the definitions I use to be more clear. I would like my site to stand out from the sea of misinformation and partial unorganized factual information. I want to make sense.

When possible, I summarize my knowledge of the topic the way you see below. Natural languages and sub-cultures are somewhat messy, so by cultivating this habit in myself I make it easier for myself to navigate terminology, and the reader have more instant clarity.

Reference

References include information about external sources - links, citations, mentions, names, and titles - and point out relations between informational objects.

Definition

Definitions are statements of the meaning of a term:

1. Intensional - give the sense of a term by naming properties that a thing must have in order to be part of the set.
   In logic and mathematics, an intensional definition gives the meaning of a term by specifying necessary and sufficient conditions for when the term should be used.
2. Extensional - list the objects that a term describes).
   Extensional definitions are used when listing the members of a set tells the questioner enough about the nature of that set, or gives more applicable information than other types of definition.
3. Ostensive - convey the meaning by pointing out examples of one or more members of a set, but not necessarily all.
   

A term may have many different senses and multiple meanings, and thus require multiple definitions. Definitions and axioms are the basis on which all of modern mathematics is constructed.

Standard

Standard is a criterion, an acknowledged measure of comparison for quantitative or qualitative value. Standards can be:

• Objects that under specified conditions represents the unit.
• Degrees or levels of requirement or excellence.
• Sets of specifications that are adopted to allow compatibility.

Knowledge - useful information, facts, methods, tips, tutorials - presentations of concepts, abstract ideas, general notions, conceptions, abstractions, theories, hypotheses, and beliefs and convictions based on factual information and experience.
