error parse quad error

[zengxianhua]

when dealing with HumanDiseaseOntology rdf representation file(url:https://github.com/DiseaseOntology/HumanDiseaseOntology/blob/master/src/ontology/doid.owl), occurs parsing errors such as
InstanceAggregator:194 - Error parsing quad [urn:x-arq:DefaultGraphNode -3be79fdb:16f03ccdbaf:-5dd9 http://www.w3.org/1999/02/22-rdf-syntax-ns#first http://purl.obolibrary.org/obo/DOID_0111104]: Subject has to be a URI, encountered: -3be79fdb:16f03ccdbaf:-5dd9

can you give any adivice?

You will have to convert the owl file to a n-triples file, e.g. using http://www.l3s.de/~minack/rdf2rdf/

What command are you running? Parsing and showing some basic stats works for me with your doid.nt file:

mvn exec:java -Dexec.args="stats \
--input.file /path/to/doid.nt \
--input.batchSize 1000000 \
--stat OBJECT_URI_COUNT --stat SUBJECT_URI_COUNT"

Very appreciate for your responding.Here is my script which results in failure.Any suggestions?
mvn exec:java -Dexec.args="convert \ --input.file doid.nt \ --output.target CSV \ --output.folder ~/Desktop/0"

One thing that I had to fix in your command was to use absolute paths to the input and output files, maybe that is your error. Otherwise only warnings were shown, the pipeline finished successfully. The output is stored in the output folder and in subfolders based on the table name, e.g. ~/Desktop/0/annotationproperty/part-00000.
