I am trying to convert a tsv file into RDF. In Linux, I downloaded OpenRefine 3.6.2, and it loads fine in the website. I can import my tsv file, etc… but the extension to convert the columns into RDF is not uploaded when I run OpenRefine. For that , what I have done is downloaded RDF extension (in a folder named extensions/rdf-extension, according to the Instructions). That folder extensions is in the same folder as the downloaded openrefine.
I have also tried with RDF transform, which is newer version of RDF extension and a new version of OpenRefine, but even when they run fine, there are not extensions running along.
I installed and reinstalled, but it is not working.
I’m sorry to say I’ve not come across any specific tutorials for using OpenRefine to work with GFF. Since it’s a tab separated value format OpenRefine will read it (although since I suspect these are generally quite large files, you will probably need a generous amount of memory allocated to OpenRefine)
I’m not at all familiar with GFF or genomics data generally, but if you could share some information on exactly what you are trying to do with some example data then it maybe I can provide some pointers as to how you can use OpenRefine in this context
