Hi 

I am using the below code to load the RDF data to janus graph -

from rdf2g import setup_graph
DEFAULT_LOCAL_CONNECTION_STRING = "ws://localhost:8182/gremlin"
g = setup_graph(DEFAULT_LOCAL_CONNECTION_STRING)

import rdflib
import pathlib

OUTPUT_FILE_LAM_PROPERTIES = pathlib.Path("path/to/ttl/file/.nt").resolve()

rdf_graph = rdflib.Graph()

rdf_graph.parse(str(OUTPUT_FILE_LAM_PROPERTIES), format="nt") 

from rdf2g import load_rdf2g 

load_rdf2g(g, rdf_graph)  

and my data looks like - <http://www.hcds.com/hcdbs_cms_geo/Africa_Concept> <http://www.w3.org/2004/02/skos/core#altLabel> "Africa"@en .

and after that vertice property, it looks like   -  property key - ns1:altLabel  and its value - Africa

                                                                                   property key - iri and its value is  -  http://www.hcdbs.com/hcdbs_cms_geo/Africa_Concept

Hi,

I am not aware of any JanusGraph properties that apply specifically to rdf or url data. Can you explain how you "upload" an rdf triple to janusgraph and give an example how the data look like as input triple and as JanusGraph vertex and edge?

Best wishes,     Marc

I have rfd data which is in turtle or xml format. Now the data is having the vertex property name in the form of URL so when I upload that data to Janus graph it converts those URL values to ns1,ns2 and goes on for each unique url.

Now my first question is how the Janus graph is doing that and how I can get those ns values.

Because I need to define my own schema for Janus graph because I need to upload bulk data and for bulk upload, the manual schema creation is required for fast upload speed. How I can crate schema for those URLs. I mean during schema creation we have to declare the property of vertices and in my case properties are url so what is the best way to achieve this.
