+format is compatible to Elasticsearch JSON (which is a key/value format serializable JSON).

+#!/usr/bin/env bash
+# This example file sends compressed JSON lines formatted files to Elasticsearch bulk endpoint
+# It assumes the index settings and the mappings are already created and configured.

+  curl -XPOST -H "Accept-Encoding: gzip" -H "Content-Encoding: gzip" \
+   --data-binary @$f --compressed localhost:9200/_bulk

+
+The result is a very basic MARC field based index, which is cumbersome to configure, search and analyze.
+In upcoming projects, I will show how to turn MARC into semantic data with context,
+and indexing such data makes much more sense and is also more fun.
