Axis D (Data Type) is the first of the four classification axes of the Errarium platform.

The main question. Axis D answers the question: "Where does the method get its information from?" — what type of input data the method uses for analysis.

5 Values of Axis D

• D0 — Formal / numerical data: date of birth, name, place, demographic data
• D1 — Symbolic external systems: planetary positions, Tarot cards, runes, hexagrams
• D2 — Bodily data: palm lines, face shape, muscle responses
• D3 — Subjective experience: test answers, self-reports, dreams, intuition
• D4 — Intersubjective field: systemic constellations, energetic interactions

Subcategories of D1

D1 splits into 4 types. D1 further divides into 4 subcategories:

• D1-N — natal (the chart at birth)
• D1-C — calendrical (the quality of time)
• D1-G — generative (an answer through a symbol)
• D1-# — numerical (numerical codes)

Combining Data Types

Many methods use several. Many methods use several types of data: for example, Applied Kinesiology (#54) = D2 + D4.
