Subclass of: gmeow:Entity

Practical Pattern

Use gmeow:Skill as a specialized kind of gmeow:Entity. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

# Worked example: skill, proficiency, and credentials. A flat gmeow:hasSkill
# says an agent HAS a skill; the reified gmeow:SkillProficiency says HOW WELL, and
# crucially on WHICH SCALE — a proficiency level is meaningless without the scale
# it is read against (P11 in spirit: a value carries its frame). A gmeow:Credential
# is a separate, independently-issued attestation OF a skill, by an issuer — having
# a credential and being proficient are distinct facts. ProficiencyLevel, scale,
# Skill and Occupation are open vocabularies, minted as needed.

# Worked example: a proficiency RISE as a SEQUENCE of tenures, never a mutation.
# Two gmeow:LearningEvent occurrents raise lillith's cycling skill — a skill
# acquisition (novice → advanced beginner) and a consolidating practice block
# (advanced beginner → expert). Each event gmeow:produces its OWN reified
# gmeow:SkillProficiency relator, scoped by its own interval; the earlier tenure
# is kept with gmeow:displayable false rather than overwritten (Principle 10).
# The trajectory of one event rides gmeow:fromLevel / gmeow:toLevel; the durable
# standing is the proficiency tenure the event produced.

Usage Advice

Use when

• Use to mint a competency or ability an agent can apply to a task — a skill in its own right, independent of any occupation, that an agent reaches via gmeow:hasSkill or a leveled gmeow:SkillProficiency.

Avoid when

• Avoid for the agent's leveled standing in the skill (that is gmeow:SkillProficiency) and for an occupation or job role (gmeow:Occupation); a skill is the ability itself, not the rating of it nor the role it serves.

How to use

• Mint the skill, align it to esco:Skill by reference where one exists, and link agents through gmeow:hasSkill for the flat case or gmeow:SkillProficiency when level, scale, or temporal scope matters.
