Struct QueryProvenanceTracker 

pub struct QueryProvenanceTracker {
    pub query_iri: NamedNode,
    pub executed_at: String,
    pub executed_by: NamedNode,
    pub input_dataset: NamedNode,
    pub result_dataset: NamedNode,
    pub query_text: Option<String>,
}

Track the provenance of a SPARQL query execution

This captures who executed a query, when, against what dataset, and what result dataset was produced. It can be exported as a PROV-O bundle.

Fields

query_iri: NamedNode

IRI identifying this specific query execution

executed_at: String

When the query was executed (XSD dateTime string)

executed_by: NamedNode

IRI of the software agent that ran the query

input_dataset: NamedNode

IRI of the input dataset (the graph queried over)

result_dataset: NamedNode

IRI of the result dataset (the query output)

query_text: Option<String>

Optional SPARQL query string

Implementations

impl QueryProvenanceTracker

pub fn new( query_iri: NamedNode, executed_at: String, executed_by: NamedNode, input_dataset: NamedNode, result_dataset: NamedNode, ) -> Self

Create a new query provenance tracker

pub fn with_query_text(self, text: impl Into<String>) -> Self

Attach the original SPARQL query text as a prov:value attribute

pub fn to_bundle(&self) -> ProvBundle

Convert this tracker to a PROV-O bundle

The bundle represents:

• result_dataset was generated by query_iri
• query_iri used input_dataset
• query_iri was associated with executed_by
• result_dataset was attributed to executed_by
