RDF Generator

A script to generate RDF data from CSL (Citation Style Language) data or Event Notifications that point to CSL data.

For the mapping we use RDF Mapping Language from RML.io.

Install

yarn install
yarn run download:rmlmapper
npm link eventlog-server

Configuration

cp .env-example .env

Demo

Create a claim database

Create the database:

yarn -s database:init

Import data from the cache database:

yarn database:import

Export all claims as JSONLD

yarn database:export

Remove all data

yarn real-clean

Generate demonstration data

The make_generated.sh creates Turtle from CSL files import/citation*.json and JSON-LD from import/event*.json files. The output is stored in import/generated.

./make_generated.sh

Export the claims database to a public web address

Make the claims database available as a JSONL and NQuads dump at http://localhost/exports/.

./export.sh

Config

The RML mapping file used for CSL to RDF mapping can be found in ./config/mapping.ttl.

The JSON-LD frame for the claims can be found in ./config/claim.jsonld and is published online as https://mycontributions.info/contexts/claim.jsonld

  • CACHE_NAME : the name of the main event notification cache table
  • POSTGRES_* : database connection parameters
  • RMLMAPPER : the path to the RML mapper JAR file
  • RMLMAP : the RML map to used to generate RDF from CSL
  • TEMPDIR : a temporary process directory
  • CONTEXT_URL : the URL of the published JSON-LD frame for claims
