Hi @rogargon,
two things at the beginning: 1. Could you correct DBPedia to DBpedia wherever you find it (also Rhizomer docu), 2. I am writing some Databus things below, but we will soon release Databus 2.0 which has some small, but breaking changes, so could be that you need to update some things later, when this happens.
Other than that the use case you have is one of the main features of the Databus. DBpedia is now extracting 5000 files monthly and nobody needs all of them. So we refactored the releases into a Maven structure. I had a look at Rhizomer and it also uses Maven in the RhizomerAPI. Databus works similar to software dependency management in Maven using a user/group/artifact/version/file structure.
For each file from the list, you need to select the appropriate artifact and version. Instead of writing <dependency><group><artifact>etc in the pom.xml things can be shortened with sparql. I made a query which covers your 18 files, see this link. Note that images are missing and abstracts are old. the latter is being fixed now. Or well you could switch to the dev artifacts: https://databus.dbpedia.org/vehnem/text/short-abstracts and https://databus.dbpedia.org/vehnem/text/long-abstracts
Another option is to 1. register at databus.dbpedia.org and 2. use the collection feature. It is like a shopping cart, where you can aggregate all files you need under one collection URL. This is what we did for latest-core. You could make a stable collection for Rhizomer once a year.
A further notice is that we build a Databus Client to help with conversion. It has a download as function, i.e. you pass it the query or collection url and tell him that you would like the files as gzip and the client will convert on download.
Please tell us, whether this succeeded, thanks.
