Verified usage

Verified import paths — ran on the pinned version, not inferred.

SPARQLClient

✓ from pymantic.sparql import SPARQLClient

✗ from pymantic import SPARQLClient

Basic usage: parse a Turtle file and query a SPARQL endpoint.

from pymantic.io import Graph from pymantic.sparql import SPARQLClient # Create a graph and parse a Turtle file graph = Graph() graph.parse('example.ttl', format='turtle') print(f"Parsed {len(graph.triples)} triples") # Query a SPARQL endpoint client = SPARQLClient('http://dbpedia.org/sparql') results = client.query('SELECT * WHERE {?s ?p ?o} LIMIT 10') for result in results['results']['bindings']: print(result)

Known issues

breakingVersion 1.0.0 dropped Python 2.x support and restructured packaging. Import paths changed from old patterns like `from pymantic import sparql`.

fix

Use `from pymantic.sparql import SPARQLClient` etc. Update imports per new package structure.

affects: >=1.0.0

deprecatedThe `lepl`-based parsers were replaced by `lark` in v0.2.0. Old code relying on `lepl` behavior may break.

fix

Ensure you use compatible syntax; lark may have stricter parsing. Update Turtle files if needed.

affects: >=0.2.0

gotchaParsing JSON-LD requires the `json-ld` optional dependency? Actually the library supports JSON-LD but may need `PyYAML` or extra care. Check documentation for exact parsing options (e.g., base URI).

fix

Install `PyYAML` if needed: `pip install PyYAML`. Use `graph.parse('file.jsonld', format='json-ld')`.

affects: all
