Varve.Sparql.Results
The SPARQL result formats — XML, JSON, CSV and TSV — read and written as streams of UTF-8.
- One reader for four formats.
ReadHeadgives the variables, or the boolean of anASK;Readadvances through the solutions, each a view of RDF terms valid until the nextRead. - SPARQL 1.2's additions: triple terms and base directions in all four.
- Chunked input. A
ReadOnlySequence<byte>is read without being joined. - Errors carry byte offset, line and column. The first error stops the reader; a malformed result document has no useful remainder.
- No
System.Xml. The XML format is read by a small non-validating reader of the subset it uses, which refuses a DTD. - One writer for four formats, into an
IBufferWriter<byte>or aStream(flushed when you choose, synchronously or not), taking each binding as anRdfTermor as a reader'sRdfTermView, and allocating nothing per solution. What a format cannot carry is stated: CSV drops datatypes and language tags by design, and XML 1.0 cannot hold U+0000.
var reader = new SparqlResultsReader(utf8, SparqlResultsFormat.Json);
while (reader.Read())
{
if (reader.Current.TryGet(0, out RdfTermView term)) { /* … */ }
}
using var writer = new SparqlResultsWriter(stream, SparqlResultsFormat.Tsv);
writer.WriteHead(["s"]);
writer.StartSolution();
writer.WriteBinding(0, RdfTerm.Iri("http://example.org/s"u8));
writer.EndSolution();
writer.WriteEnd();
await writer.FlushAsync();
