GraphDB workbench won't load .gz complressed .brf files from Mac

I am using GraphDB 9.1.1, and I am speaking about my experiences with the web-based Workbench.

I have a folder of .brf binary RDF files on my Mac. Some are .zip compressed, some are .gz compressed, and some are uncompressed.

From Chrome or Firefox under macOS Catalina 10.15.7: When I click on Import (in the Workbench's left-hand menu) -> RDF -> Upload RDF Files, I can upload the .brf.zip files and the uncompressed files, but not the .brf.gz files. They are greyed out.

greyed-out .brf.gz files in GraphDB import dialog

Loading one of the .brf.gz files from Chrome in Windows 10 is successful. With some little effort, I could do the whole thing from Windows or Ubuntu Linux, but my team hasn't planned on switching to a newer GraphDB version yet.

The Upload RDF Files hover-over help says

The supported RDF formats are ... .brf ..., as well as their .gz versions and .zip archives

Solution

  • It looks like there is some MacOS issue that won't accept the .gz variants of file extensions (e.g. .brf.gz, .ttl.gz etc) even though they are correctly listed by GraphDB as accepted for the file dialog. There is no workaround in Safari but there is one in Chrome and Firefox:

    1. Click the Options button in the lower left corner.
    2. Choose "All files" instead of "Customised Files".
