Struct KnowledgeGraph 

pub struct KnowledgeGraph {
    pub triples: Vec<Triple>,
    pub provenance: Vec<String>,
    pub equivalence_classes: Vec<HashSet<String>>,
    pub canonical_uris: HashMap<String, String>,
}

A merged knowledge graph assembled from multiple endpoints

Fields

triples: Vec<Triple>

All triples gathered from the federation

provenance: Vec<String>

Provenance: which endpoint contributed each triple index

equivalence_classes: Vec<HashSet<String>>

Entity equivalence classes after sameAs resolution

canonical_uris: HashMap<String, String>

Canonical URIs chosen for each equivalence class (representative URI)

Implementations

impl KnowledgeGraph

pub fn new() -> Self

Create an empty knowledge graph

pub fn triple_count(&self) -> usize

Return the number of distinct triples

pub fn is_empty(&self) -> bool

Return true if the knowledge graph has no triples

pub fn canonical<'a>(&'a self, uri: &'a str) -> &'a str

Resolve a URI to its canonical form (or return the URI unchanged)
