Freebase data sets cannot be imported into virtuosos

[yeqyqx]

Hello, my thinking is to upload data from Freebase to virtuoso for easy query, but when I run ld_dir('.', 'FilterFreebase', 'http://freebase.com/'); rdf_loader_run(); After this command, I think it may be because the data is too big or other reasons, I waited for ten hours and did not get the reply of the end of the upload. May I ask how I can check the upload progress, or is there any problem with my operation? I can access the virtuoso interface via port 8890. Can I check uploads here?

And ld_dir('.', 'FilterFreebase', 'http://freebase.com/') : What does "http://freebase.com/" in LD_DIR ('.', 'FilterFreebase', 'http://freebase.com/') do when it says 404 not found
