Load set of skos files

[Sefiane Touhami]

Hi all,

Is the command "annif loadvoc" allows to load a tar file which contains a set of skos files ?

Hi,

No, loadvoc command cannot handle a tar-archive of vocabulary files. And not multiple vocabulary files in any way: currently the vocabulary to load needs to be one file, in some of the supported formats: https://github.com/NatLibFi/Annif/wiki/Subject-vocabulary-formats

Maybe you can write the terms of each individual SKOS files into tsv files, which could then just be concatenated together to one tsv file? Or possibly there is a tool to concatenate SKOS files directly to one? Surely someone here knows more about the SKOS tools than me.

Hi,

for merging SKOS files you can use any RDF tools. For example, rdflib
(which is used in Annif) comes with the utility rdfpipe, which works
well for this although it can be a bit slow. For example, to merge two
SKOS files into a single Turtle file, you can use a command like this:

rdfpipe file1.ttl file2.ttl -o turtle >merged.ttl

Hope this helps!
