Unable to import data

[ghost]

Hello,

I have installed a new instance of iQvoc and I am unable to import any of the data I was able to import to my previous instance. Even the sample hobbies.nt file. The process starts and takes forever without any error and without succeeding. How can I troubleshoot? How can I know the error to solve? Is there anything related to workers or etc.?

Please advise as this is very critical. Thank you!
Regards.

Can confirm, tried different .nt files - none of them could be imported. Process never ends, for some files it is already running since 4+ days (according to the UI), while I already restarted the app several times.

Something I found in the log:

Especially the last line looks interesting:
Cannot render console from <my.IP.address>! Allowed networks: 127.0.0.1, ::1, 127.0.0.0/127.255.255.255
Could this be a network / access rights problem? I have the iQvoc instance running on a remote server, connected via VPN to that network and accessing the web ui from my local PC.

Hi, sorry for the inconvienence. How did you import your data? Please note that uploading an nt-file via webui only uploads an n-triples file and creates an corresponding import job. This jobs needs to be execute using an job worker (e.g. by running bundle exec rake jobs:workoff.

❯ be rake -T jobs
...
rake jobs:clear                 # Clear the delayed_job queue
rake jobs:work                  # Start a delayed_job worker
rake jobs:workoff               # Start a delayed_job worker and exit when all available jobs are complete

If you don't want to use webui for initial data loading, you could also use CLI: rake iqvoc:import:url URL=data/hobbies.nt NAMESPACE='http://hobbies.com/' (see https://github.com/innoq/iqvoc/wiki/Importing)

Hello @mjansing, yeah I initiated the import via the webui. Thanks for the hint with those rake jobs (work*), that definitely helped.

Still, I have problems importing SKOS vocabularies, most of the time I work with Turtle (.ttl) or RDF/XML (e.g. https://skos.um.es/unesco6/downloads.php). I tried Skosify & rdf2rdf for the conversion to NT (n-triples), result files always look valid to me.

When importing the unesco6 vocabulary I get a lot of the following log lines:

  WARN -- : SkosImporter: Unknown namespaces. Skipping <http://skos.um.es/unesco6/221214> skos:notation "2212.14"
  WARN -- : SkosImporter: Invalid origin. Skipping <http://skos.um.es/unesco6/221214> skos:notation "2212.14"

I think iQvoc does this for every triple of the vocabulary, since 0 concepts or collections are visible in the iQvoc gui or even in the mysql db. What is the problem with the unesco6 (@Prefix unesco6: http://skos.um.es/unesco6/ .) namespace?

Thanks!
