yes, this is intentional. It is still more for friends and family. We 
will do a refactoring step that changes some uploading interfaces and 
this switch gets more difficult the more users we have, so we keep the 
uploading part low profile. The downloading part works well, see below.

For uploading, you basically need an own fileserver with webdav access. 
Since this is NIF, I could give you access to our group's file server. 
The you would need to follow the old instructions which are outdated and 
complex, but some people managed to succeed. See the readme of this repo 
https://github.com/dbpedia/databus-maven-plugin/tree/master (you can 
also switch to dev-2.0 where instructions are rewritten at the moment: 
https://github.com/dbpedia/databus-maven-plugin/tree/dev-2.0

If you would like to collect all NIF datasets, that you find and upload 
them, we can help you with it by answering questions.

This works very well already:

Option 1: You maintain a sparql query that feeds the dashboard. 
Currently, we extract the NIF DBpedia extraction containing full text of 
all wikipedia articles of all languages. You can see them here: 
https://databus.dbpedia.org/dbpedia/text/

The query can be maintained by a collection. I created one here 
https://databus.dbpedia.org/kurzum/collections/nif-datasets

If you have an account you can use the GUI to create collections. These 
are de-facto individual DCAT catalogues with stable IDs.


Option 2 (not implemented yet): we are doing VOID for all datasets on 
the bus, so there you could query for all data that uses NIF and feed 
the metadata into the dashboard.
