name: hierarchical-tagging description: Hierarchical tag system based on library classification principles for content classification. Use when the user asks to tag, categorize, or label content (files, bookmarks, notes, articles, books, documents, etc.) or when they want to organize information using tags. Also use when user asks to suggest tags, review existing tags, or improve tag organization.
Hierarchical Tagging System (Library Classification Based)
A structured knowledge domain classification system following library science principles with two-level hierarchy, based on established library classification standards.
Classification Principles
Based on library classification standards:
- Single Criterion: Each level uses ONE classification standard
- Level 1: By knowledge/practice domain (what the content is about)
- Level 2: By subdomain within that field
- Exhaustive Coverage: Child categories fully cover parent category
- No gaps in coverage
- No content falls outside the system
- Mutual Exclusivity: Categories at same level don’t overlap
- Each item belongs to ONE primary domain
- No sibling categories are compatible concepts
Tag Structure
Format: domain/subdomain
- Level 1: Broad knowledge domain (follows established library classification)
- Level 2: Specific subdomain (stops at second level)
- Uncertainty: Use top-level only when subdomain unclear
Level 1: Knowledge Domains
Based on standard library classification with user-specific additions:
philosophy/ # Philosophy - fundamental questions
religion/ # Religion - religious studies, theology
occultism/ # Occultism - esoteric, mystical traditions
psychology/ # Psychology - human mind and behavior
psychoanalysis/ # Psychoanalysis - psychoanalytic theory and practice
social-science/ # Social Sciences - human society
natural-science/ # Natural Sciences - natural phenomena
formal-science/ # Formal Sciences - abstract structures
medical-science/ # Medicine - human health
engineering/ # Engineering - technical implementation
applied-arts/ # Applied Arts - functional artistic creation
fine-arts/ # Fine Arts - aesthetic artistic creation
linguistics/ # Linguistics - study of language itself
literature/ # Literature - literary creation and study
life-practice/ # Life Practice - daily life skills
history/ # History - study of past events
Critical Definition: literature/
literature/ = Literary creation AND literary studies
✅ Included:
- Fictional works: novels, short stories, poetry, drama
- Literary criticism and theory
- Literary movements and styles
- Textual analysis
❌ NOT included (classify by content domain):
- Political essays →
social-science/politics - Philosophical essays →
philosophy/[subdomain] - Travel writing →

history/biography # Historical biographies
Key principle: Use history/ for historical studies. For contemporary subjects, use their domain (e.g., current politics → social-science/politics, not history/)
linguistics/
linguistics/phonetics # Phonetics, phonology
linguistics/syntax # Syntax
linguistics/semantics # Semantics
linguistics/pragmatics # Pragmatics
linguistics/comparative # Comparative linguistics
linguistics/applied # Applied linguistics, language teaching
linguistics/historical # Historical linguistics
Domain Boundaries & Special Cases
psychology/ vs psychoanalysis/
- psychology/: Scientific, empirical approaches to studying mind and behavior
- psychoanalysis/: Psychoanalytic theory, unconscious processes, therapeutic practice based on psychoanalytic tradition
religion/ vs occultism/
- religion/: Organized religions, theology, religious practices
- occultism/: Esoteric, mystical, and occult traditions (often outside mainstream religion)
psychology/ vs medical-science/psychiatry
- psychology/: Non-medical study of mind and behavior
- medical-science/psychiatry: Medical treatment of mental disorders
philosophy/mind vs psychology/
- philosophy/mind: Philosophical questions about consciousness, mental states
- psychology/: Empirical study of mental processes and behavior
history/thematic vs domain-specific history
Use history/thematic for:
- History of science →
history/thematic(notnatural-science/history) - History of philosophy →
history/thematic(notphilosophy/history) - Intellectual history →
history/thematic
This avoids creating “/history” subdivisions under every domain.
Tagging Workflow
- Identify content subject: What is this primarily about?
- Determine domain: Which Level 1 category matches the subject?
- Assess specificity: Can you confidently identify the subdomain?
- Assign tag:
- Confident → Full path:
domain/subdomain - Uncertain → Top-level:
domain
- Confident → Full path:
- Validate: Does this help retrieval? Is it the most accurate fit?
Common Tagging Scenarios
Scenario 1: Political Commentary Article
Content: Opinion piece on recent election
Tag: social-science/politics
Reasoning: Classify by CONTENT (politics), not form (article/commentary)
Scenario 2: Restaurant Review
Content: Review of a local restaurant
Tag: life-practice/gastronomy
Reasoning: Practical dining experience, part of life practice
Scenario 3: Smartphone Review
Content: Detailed tech review of new phone
Tag: life-practice/consumption OR engineering/information (if highly technical)
Reasoning: Consumer-focused → life practice; Engineering-focused → engineering
Scenario 4: Film Criticism
Content: Analysis of a movie’s artistic techniques
Tag: fine-arts/critique OR fine-arts/film
Reasoning: Artistic criticism belongs in fine arts
Scenario 5: Modernist Novel
Content: James Joyce’s “Ulysses”
Tag: literature/modernism
Reasoning: Creative work tagged by literary movement/style
Scenario 6: Literary Theory Book
Content: Book on narratology
Tag: literature/narratology OR literature/theory
Reasoning: Literary studies work
Scenario 7: Psychoanalytic Case Study
Content: Freudian analysis of a patient
Tag: psychoanalysis/freudian
Reasoning: Psychoanalytic practice and theory
Scenario 8: Religious Text Commentary
Content: Commentary on Buddhist sutras
Tag: religion/buddhism
Reasoning: Religious studies content
Scenario 9: Tarot Guide
Content: Book on tarot card reading
Tag: occultism/divination
Reasoning: Divination practice within occultism
Scenario 10: History of Science
Content: Book on scientific revolution
Tag: history/thematic
Reasoning: Historical study of intellectual/scientific development
Scenario 11: Cognitive Science Paper
Content: Research on memory formation
Tag: psychology/cognitive
Reasoning: Scientific psychological research
Scenario 12: Philosophy of Mind Essay
Content: Essay on consciousness
Tag: philosophy/mind
Reasoning: Philosophical inquiry, not empirical psychology
Scenario 13: Travel Essay
Content: Personal travel narrative
Tag: life-practice/travel
Reasoning: Non-fiction prose classified by content
Scenario 14: Scientist Biography
Content: Biography of Einstein
Tag: history/biography OR natural-science/physics
Reasoning: Can use either depending on emphasis
Scenario 15: Contemporary Politics
Content: Analysis of current political situation
Tag: social-science/politics
Reasoning: Current events → use domain, not history/contemporary
Edge Cases
Cross-disciplinary Content
When content genuinely spans multiple domains, choose the PRIMARY focus:
- “Philosophy of Religion” →
philosophy/ORreligion/(judge by approach) - “History of Psychoanalysis” →
history/thematicORpsychoanalysis/(judge by emphasis) - “Bioethics” →
philosophy/ethicsORmedical-science/(judge by approach) - “Psychology of Religion” →
psychology/ORreligion/(judge by primary methodology)
Uncertain Subdomain
When subdomain is unclear, use top-level:
- Political content but unclear aspect →
social-science/politicsOR justsocial-science - General philosophy introduction →
philosophy - Mixed literary genres →
literature
Historical vs Contemporary
- Historical study →
history/[period]orhistory/thematic - Contemporary topic → Use domain (e.g.,
social-science/politics) - Biography of historical figure →
history/biography - Biography of living person → Relevant domain
Tag Expansion Guidelines
Before creating new subdomains:
- Verify alignment with library classification standards
- Ensure 5+ items warrant the subdivision
- Check it doesn’t overlap with existing subdomains
- Maintain mutual exclusivity with sibling categories
- Document the new subdomain clearly
Common Mistakes to Avoid
❌ Mixing form and content: “This is an essay, so literature” → NO, classify by content
❌ Over-specificity: Creating three-level tags → Stop at level 2
❌ Form-based tags: “review”, “essay”, “article” as primary classification → Classify by content domain
❌ Redundant tagging: Using both social-science AND social-science/politics → Use specific only
❌ Wrong literature usage: Political essay as literature → NO, use social-science/politics
❌ Historical confusion: Current events as history → NO, use relevant domain; history is for historical studies
❌ Domain duplication: Creating natural-science/history → NO, use history/thematic
Summary: Classification Logic
| Content Type | Classification Logic | Example Tag |
|---|---|---|
| Political essay | By subject (politics) | social-science/politics |
| Product review | By practical domain | life-practice/consumption |
| Film critique | By art form | fine-arts/critique |
| Modernist novel | By literary movement | literature/modernism |
| Literary theory | By critical approach | literature/theory |
| Psychoanalytic work | By psychoanalytic school | psychoanalysis/[school] |
| Religious text | By religion | religion/[religion] |
| Occult practice | By occult tradition | occultism/[tradition] |
| Psychology research | By subfield | psychology/[subfield] |
| Travel writing | By practical domain | life-practice/travel |
| Biography | By subject’s field or period | history/biography or domain |
| History of X | By historical approach | history/thematic |
Key Principle
Always classify by WHAT THE CONTENT IS ABOUT, not HOW IT IS WRITTEN.
- Writing style (essay, article, review, commentary) does NOT determine classification
- Subject matter and knowledge domain DO determine classification
- For literature: creative works by genre/movement; critical works by study approach
- Historical studies use
history/; contemporary topics use their domain
