Dialect differences

RDF is a file format and dBase 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.

Propertyin RDFin dBase
port—(file-based)
identifiersXML attribute quoting; entities for reserved characters—
row limit—(driver dependent)
datesxsd:dateTime typed literalsDate (D)
long text—Memo (M)
binaryxsd:base64Binary typed literals—

No counterpart

  • RDF values of kind Date and time have nowhere to go in dBase.
  • RDF values of kind Binary have nowhere to go in dBase.
  • RDF values of kind JSON have nowhere to go in dBase.
