process

The process directory contains:

• get_wikidata_issns.py - retrieves all ISSNs from Wikidata and builds a local index of issn -> wikidata id.
• match_to_wd.py - matches the local data in data/journals.csv to Wikidata.
• to_rdf.py - converts the matched data in data/journals_matched.csv to a basic RDF model.

ldf

Running the LDF Server requires nodejs and npm. To run first install the dependencies:

• $ cd ldf
• $ npm install

To start the server run:

$ node_modules/ldf-server/bin/ldf-server config.json 5000

View the config.json file to see how the LDF server reads your triple file.

A Procfile is included that will allow you to run the server on Heroku.
