Hi Alexander,
If you prefer to leave them uncompressed then fine, change the reference in the
ld_dir () procedure to "*.nt" in that case. The gz recommendation was more to
save space on the machine ...
BTW, their is rogue "i" character on the end of the graph name in the ld_dir
command below I just noticed, which should be:
"ld_dir ('/opt/lgdelement', *.gz', 'http://linkedgeodata.org#')"
Best Regards
Hugh Williams
