NSSI, short for NERVE Secure Scalable Infrastructure and pronounced "Nessie,” is an application for managing the data processing workflows used by NERVE and other LINCS conversion tools. NSSI includes a set of modularized services for loading resources, processing resource content, and saving results, and can be extended to work with other services outside of the NSSI application itself.


LINCS uses NSSI alongside NERVE to run data conversion workflows for generating Linked Data (LD) from structured and semi-structured data data. Clients submit jobs to NSSI specifying a predefined workflow and receive a Uniform Resource Identifier (URI) from where they can retrieve results when the processing completes.

NSSI stores data until users delete it. Data is stored in the NSSI database, on S3, and/or in Elucidate. Data produced and stored by NSSI will be subject to access controls.

NSSI can be run locally using Docker.
