prov-lineage SKILL.md skillA
prov-lineage from sparq-org/sparq is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add sparq-org/sparq/prov-lineage@git:20261103.5cfd364Pins git:20261103.5cfd364 in mdr.lock. Pin the fingerprint instead.

Capture W3C PROV-O data lineage for DERIVED RDF, or explain a missing BGP target binding: record CONSTRUCT/DESCRIBE, SPARQL UPDATE, and reasoner-materialization lineage; under the opt-in `why-not` feature, report exactly which grounded BGP triple patterns are absent. Off by default; does not touch sparq-core/sparq-engine's lean build.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# sparq-prov — W3C PROV-O lineage for derived data
[W3C PROV-O](https://www.w3.org/TR/prov-o/) is the standard RDF vocabulary for
provenance: a `prov:Entity` was generated by a `prov:Activity` that `prov:used`
some inputs, so the entity `prov:wasDerivedFrom` them. `sparq-prov` records that
lineage for data sparq **derives** — today, the result of a `CONSTRUCT`/`DESCRIBE`
query (a new RDF graph produced from the queried data).
`sparq-prov` is the **opt-in public surface** for this. Add it explicitly; it is
**not** in sparq's default build (`sparq-core`/`sparq-engine` stay lean, the wasm
artifact is unchanged unless you pull it in). The capability is therefore **off by
default at the dependency level** — the leanest gating, with zero core overhead.
## Add the dependency
```toml
[dependencies]
sparq-prov = { path = "crates/sparq-prov" } # or your workspace path
sparq-core = { path = "crates/sparq-core" } # same checkout, so `Graph` types match
oxrdf = { version = "0.3", features = ["rdf-12"] }
```
## Derive a graph + capture its lineage
`derive_construct` runs the query, times it, and returns a `Derivation` holding

How to install
mdr add sparq-org/sparq/prov-lineage@sha256:683eed5bde044550The line at the top of this page pins the label git:20261103.5cfd364, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
