What’s in the sections

RDF

A Linked Data browser, all the data is browsable via HTTP and is rendered neatly in HTML. Here is an example of the raw data:

    @prefix dc: <http://purl.org/dc/elements/1.1/> .
    @prefix doacc: <http://purl.org/net/bel-epa/doacc#> .
    @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
    @prefix skos: <http://www.w3.org/2004/02/skos/core#> .
    doacc:D065850e9-9912-4983-9ac3-2ece19e55f32 a doacc:PoWscheme ;
        rdfs:label "scrypt-n-f"@en ;
        dc:description "Uses a fixed N-factor to avoid anticipated network issues"@en ;
        rdfs:isDefinedBy <http://purl.org/net/bel-epa/doacc> ;
        skos:prefLabel "scrypt-n-f"@en .

SPARQL

SPARQL is the query language used for interrogating the dataset. Minkiz provides a web-ui SPARQL endpoint for posing queries.

    PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
    SELECT ?node ?label WHERE 
    { ?node skos:prefLabel ?label . }
    LIMIT 5

OWL

OWL is the language for defining the meaning of the labels for the recorded metadata. The result is an ontology - ontologies for DOACC and CCY are here rendered in HTML for convenient consulting.

    doacc:Cryptocurrency a owl:Class ;
        rdfs:label "Kryptomena"@cs,
            "Crypto-Währung"@de,
            "Cryptocurrency"@en,
            "Cryptodivisa"@es,
            "Crypto-monnaie"@fr,
            "暗号通貨"@ja ;
        rdfs:comment "Kryptomena."@cs,
            "Ein Crypto-Währung."@de,
            "A cryptocurrency."@en,
            "Una cryptodivisa."@es,
            "Une crypto-monnaie."@fr,
            "暗号の通貨"@ja ;
        rdfs:isDefinedBy  ;
        ns:term_status "unstable" ;
        skos:prefLabel "Cryptocurrency"@en .
