Codec Class

• CURIE: gmeow:CodecClass
• IRI: https://blackcatinformatics.ca/gmeow/CodecClass
• Category: class
• Defined by: gmeow:slices/gts
• Box roles: ConfigBox role, TBox role (What is this?)

The capability class of a transform codec — encode, compress, or encrypt (spec §8). Determines the degradation path when the capability is missing: unknown-codec or missing-key opacity.

Structure

Subclass of: gufo:QualityValue

Practical Pattern

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

Usage Advice

Use when

• Use as the value vocabulary for codec capability classes — the small set (encode, compress, encrypt) that determines whether a missing capability yields unknown-codec or missing-key opacity.

Avoid when

• Avoid minting classes as subclasses (they are individuals) and avoid using this to name a concrete codec; it is the capability category, while gmeow:TransformCodec names the algorithm.

How to use

• Reference the seeded classes (encode, compress, encrypt) from a codec via gmeow:codecClass; encrypt-class codecs degrade to missing-key opacity, the others to unknown-codec opacity when a reader lacks the library.
