was derived from

• CURIE: gmeow:wasDerivedFrom
• IRI: https://blackcatinformatics.ca/gmeow/wasDerivedFrom
• Category: property
• Defined by: gmeow:slices/provenance
• Box roles: CBox role, RBox role (What is this?)

Relates a derived thing to the thing it was derived from — e.g. a text extraction, summary, or embedding to its source; a commit to its parent commit; a trajectory to its sample stream. The derivation's confidence and generating agent are recorded with gmeow:confidence and gmeow:wasGeneratedBy. Domain-free so that events, endurants, and information objects may all participate in derivation chains.

Structure

Property shape: object property

Practical Pattern

Use gmeow:wasDerivedFrom when the definition matches the source fact. Prefer a narrower GMEOW term when one exists, and keep projection concerns in the mapping layer.

# summary records WHERE it came from (gmeow:wasDerivedFrom → the source), HOW it
# was produced (gmeow:wasGeneratedBy → an Activity), and WHO ran it
# (gmeow:wasAttributedTo → an Agent). The importer is a gmeow:SoftwareAgent that
# self-records its own run — the producer of the provenance is inside it.
# (How much to trust the derivation is gmeow:confidence — an annotation on the

# A-box property on the individual, so it is out of scope for this flat example.)

Usage Advice

Use when

• Use to link a derived artifact to its source — a summary, text extraction, or embedding to the document it came from, a commit to its parent — building the derivation chain that lets consumers trace a value back to its origin.

Avoid when

• Avoid for the activity that did the deriving (use gmeow:wasGeneratedBy → gmeow:Activity) and for mere topical aboutness (use gmeow:hasAboutness); derivation asserts genealogical descent, not subject matter.

How to use

• Point the derived thing at its source; carry the derivation's gmeow:confidence and lossiness on the statement layer (a summary is a lossy projection of its source), and attach gmeow:wasGeneratedBy to name the generating activity and, through it, the agent.

Examples

• ex:summary gmeow:wasDerivedFrom ex:report.
