Hi,
I get another JSON-LD error with using the @context
https://w3id.org/bundle/context that I need to check further what is
the cause of that (it works fine with JSON-LD Playground).

I don’t know whether it is the same thing, but I noticed (working with
3.1.1-SNAPSHOT) that following test, that attempts to read a simple jsonld
document with an external context
public class TestJsonLDReader {
@Test public final void test() {
String jsonld = "{\"@id\":\"_:b0\",\"@type\":\"http://schema.org/Person\",\"name\":\"John
Doe\",\"@context\":\"http://schema.org/\"}";;
StringReader reader = new StringReader(jsonld);
Model m = ModelFactory.createDefaultModel();
m.read(reader, null, "JSON-LD");
m.write(System.out, "TURTLE");
}
}
gives:

It seems that there is a conflict between the version of http-client cache used
by JSON-LD java 0.8.2 (4.5.1), and the one that wants jena (4.2.6). Jena seems
to really want to choose its version, cf pom/xml:
+ /*
+ <dependency>
+ <groupId>com.github.jsonld-java</groupId>
+ <artifactId>jsonld-java</artifactId>
+ <version>${ver.jsonldjava}</version>
+ <exclusions>
+ <exclusion>
+ <groupId>commons-logging</groupId>
+ <artifactId>commons-logging</artifactId>
+ </exclusion>
+ <!-- Exclude so we use our choice of versions -->
+ <exclusion>
+ <groupId>org.apache.httpcomponents</groupId>
+ <artifactId>httpclient-cache</artifactId>
+ </exclusion>
+ <exclusion>
+ <groupId>org.apache.httpcomponents</groupId>
+ <artifactId>httpclient</artifactId>
+ </exclusion>
Best,
