NAKALA is a Huma-Num interoperable and secure service which enables research teams to deposit all types of documented digital data (text files, sounds, images, videos, 3D objects, etc.) in a secure repository in order to share them.

NAKALA separates the data storage (files and metadata) from the different methods of use and editorialization. NAKALA ensures both data and metadata accessibility as well as their citability over time through stable identifiers provided by Huma-Num. NAKALA is entirely based on technologies used for Linked Data which particularly enable to make metadata interoperable, i.e. to possibly connect them to other existing repositories according to the logic of linked open data. In addition, NAKALA also offers a package (NAKALONA) to expose metadata that allows to reference them with specialized search engines such as ISIDORE. Thus, NAKALA is part of a coherent system of services set up by Huma-Num to facilitate the access, description, preservation and long-term archiving of Humanities and Social Sciences research data.

This repository mainly provides three types of services: - assignation of a PID (Persistent IDentifier) making data and metadata citable; - permanent data access; - dissemination of metadata through a Triple Store and OAI-PMH.
