I'm confused. Did you change your operating system since you used it last time? As it was working before, was it MacOS or Linux and now you're using Windows? On 12.04.21 19:24, Zlatareva, Neli (Computer Science) wrote: Hi Lorenz, thank you for the quick response. bin/arq --help does not work (

Hi Lorenz, thank you for the quick response. bin/arq --help does not work (from ...\apache-jena-4.0.0 directory). The error is 'bin' is not recognized as an internal or external command, operable program or batch file. I tried to run arg --help from the bin directory and it gives me the same error

Hi Brandon, There are a number of possible steps after a compaction - delete, archive, compress-archive-delete. This sounds like a natural thing to have but at the same time I'm a bit wary of adding features one at a time because a feature is a commitment to maintain and some other concern m
