has skill

Purpose

This edge represents that the student possesses the skill . The has-skill relationship connects students (actors) to skills (properties), creating a concrete reference to an abstract capability.

Relationship Type

Edge Type: has-skill (possession)

Direction: student → skill (student possesses skill)

Participants:

• Source: v:student:<student-name> (the student who has the skill)
• Target: v:skill:<skill-name> (the skill that is possessed)

Meaning

This edge indicates that <student-name> has acquired and currently possesses <skill-name>. This could be:

• A prerequisite skill the student already has (enabling module study)
• A skill the student has learned (achievement during learning journey)
• A skill verified through assessment

Property Possession Pattern

This edge follows the property possession pattern:

• Property as referent (abstract): The skill <skill-name> is an abstract capability definition
• Possession as reference (concrete): This edge creates a concrete instance where <student-name> possesses that skill
• The skill becomes "real" for this student through this possession relationship

Examples

Prerequisite Possession:

# Student has prerequisite skill needed for a module
source: v:student:knowledge-complex-learner
target: v:skill:simplicial-complex-fundamentals
# This enables studying modules that require this skill

Acquired Skill:

# Student has learned a new skill
source: v:student:alice-researcher
target: v:skill:chart-creation
# This achievement unlocks new learning opportunities

Participation in Faces

has-skill edges participate in prerequisite faces:

type: face/prerequisite
vertices:
  - v:student:<student-name>          # has-skill edge source
  - v:skill:<skill-name>              # has-skill edge target
  - v:learning-module:<module-name>   # requires-skill edge source

This triangle means: Student with skill can study module requiring that skill

Constraints

• Source MUST be a student vertex (v:student:*)
• Target MUST be a skill vertex (v:skill:*)
• Each student-skill pair should have at most one has-skill edge
• Skill must be defined (skill vertex should exist)
• Student must be defined (student vertex should exist)

Verification

This edge can be verified using:

python scripts/verify_template_based.py 01_edges/<edge-file>.md --templates templates

Note: This template defines the has-skill relationship between students and skills. It follows the property possession pattern where the abstract skill becomes concrete through possession by a specific student.
