Sponge is Coral's data import layer. It is an Extract, Transform, and Load command line tool designed to:

• Read data from a foreign source,
• Translate the schema into Coral conventions, and
• POST entities to our service layer for insertion.

All of the Sponge documentation (including installation instructions) can be found in the Coral Project Documentation.

The Sponge documentation lives in Github in the coralproject/docs/docs_dir/sponge repository.
