I'm trying to combine all my ttl files into one data dump, but when I try to do
rdfproc test_big parse vm_base.ttl turtle
It's taking forever, still waiting..., making me suspect it has stuck somewhere.
Is there a better alternative which can do this faster? Other than I manually open all files in Protégé, which is what I have been doing, and find it time-consuming.
The file, if you need to test: https://github.com/miranda-zhang/cloud-computing-schema/blob/master/example/sparql-generate/result/azure/v1.0.1/2019-03-07/vm_base.ttl
Edit
I did a test with riot merging 2 files, but why does it give duplicated @prefix declarations?
