YAGO TTL to Local Virtuoso Instance

Question

I am trying to load the YAGO ontology to a local instance of Viruoso database. YAGO is available here in 7zip format. However, using the online gui I am unable to load the 7zip file. Using the terminal I am still unable to load the db. However, if I extract a specific ttl file from the 7zip file I am able to load it using both ways. What is the problem with the full 7zip file? In addition what prefix should I use as third parameter in the ld_data command?

Answer 1

According to the documentation, currently Virtuoso only supports gzip compression format. So one option would be to use the Bulk Loading RDF Source Files features of Virtuoso with the extracted files. For example, you can load all the files using

> isql
SQL>  ld_dir ('/path/to/extracted/files', '*.ttl', 'http://graph.name');
SQL> rdf_loader_run();
