Type mapping
| Value kind | in RDF | in DBF |
|---|---|---|
| Int | "1234"^^xsd:int | Numeric(10,0) |
| Bigint | "9007199254740993"^^xsd:long | Numeric(19,0) |
| Decimal | "1234.56"^^xsd:decimal | Numeric(p,s) |
| Float | "1.234e10"^^xsd:double | Float |
| Text | plain literal without a datatype | Character(n) |
| Long text | plain literal; newlines allowed inside | Memo |
| Date | "2026-09-18"^^xsd:date | Date |
| Datetime | "2026-09-18T14:30:00Z"^^xsd:dateTime | (none) |
| Binary | "base64..."^^xsd:base64Binary | (none) |
| Boolean | "true"^^xsd:boolean | Logical |
| JSON | a literal, or reified as its own sub-graph | (none) |
Dialect differences
RDF is a file format and DBF 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 DBF |
|---|---|---|
| port | — | (file-based) |
| identifiers | XML attribute quoting; entities for reserved characters | — |
| row limit | — | (driver dependent) |
| dates | xsd:dateTime typed literals | Date (D) |
| long text | — | Memo (M) |
| binary | xsd:base64Binary typed literals | — |
| 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 | Tables of rows and columns |
| ceiling | Whole document is usually parsed into memory | — |
No counterpart
- RDF values of kind Date and time have nowhere to go in DBF.
- RDF values of kind Binary have nowhere to go in DBF.
- RDF values of kind JSON have nowhere to go in DBF.
