Dialect differences
RDF is a file format and MongoDB is a database server, so the target has to be told the types the file never carried – the rows below are where the two sides diverge.
| Property | in RDF | in MongoDB |
|---|---|---|
| port | — | 27017 |
| identifiers | XML attribute quoting; entities for reserved characters | No identifier quoting - names are plain strings |
| row limit | — | .limit(n) / $limit aggregation stage |
| dates | xsd:dateTime typed literals | ISODate() / BSON date (millisecond epoch internally) |
| long text | — | String (BSON string, no length limit) |
| binary | xsd:base64Binary typed literals | BinData (BSON binary subtype) |
| separator | XML elements (rdf:Description / rdf:resource) | — |
| encoding | Declared in the XML declaration | — |
| typing | Every value is a resource or a typed literal | — |
| shape | Graph of triples; there are no rows or columns | Collections of documents with optional nesting |
| ceiling | Whole document is usually parsed into memory | — |
Command line
| Side | Command |
|---|---|
| MongoDB | mongoexport --collection=c --out=f.json |
| MongoDB (load) | mongoimport --collection=c --file=f.json |
