How to create RDF graph from source data #1

Open GiulioC opened 6 years ago

GiulioC commented 6 years ago

Hi, which tool do you use to generate the RDF graph from the source data ? For instance, I am trying to generate a graph from the source file museum-29-edm/sources/s01-cb.csv and its R2RML model museum-29-edm/models-r2rml/s01-cb.csv-model.ttl but the solutions I have tried did not seem to work. Any suggestion ?

Thank you, Giulio.

Hi Giulio, I modeled my sources using Karma http://usc-isi-i2.github.io/karma/. The tool lets you model sources via a graphical user interface and allows you to generates R2RML model and RDF data for the modeled source. Karma is open source and available on GitHub https://github.com/usc-isi-i2/Web-Karma and it has a nice user guide https://github.com/usc-isi-i2/Web-Karma/wiki. I am not sure what the current state of the system is as I no longer work at ISI, but if you have any question, you can post on Karma's GitHub page, I see that their bug page is pretty active. Best, Mohsen
