Open Semantic ETL: Export results to JSON

This is one of the output plugins for standalone installations of Open Semantic ETL without a full search engine, for example for some data analysis, enrichment or jobs saved to an output file or to a(nother) (maybe light-weight) database.

So if you set config['export'] = 'export_json' so the output of etl-file *filename* or etl-web *url* will be exported as JSON.

To write the JSON output to a file, set the argument --outputfile, for example

etl-file --outputfile *outputfilename* *inputfilename*

or

etl-web --outputfile *outputfilename* *uri*

API with JSON results

If you use output plugins to write your data to a search index like Solr or Elastic Search, you can read and filter it with their more powerful search APIs:

For example REST-API of Solr for searching or / and getting data in XML or JSON format or use Solr Client APIs to get data with your favorite programming language.
