This document provides an intuitive introduction to the NIDASH Data Model for neuroimaging data sharing. NIDASH defines a core vocabulary that extends the PROV Data Model for provenance with terms that capture information about neuroimaging research, from data acquisition to analysis and results. This primer explains the fundamental NIDASH concepts and provides examples of its use. The primer is intended as a starting point for neuroimaging scientists or developers interested in using or creating apps with NIDM.

Overview

This section provides an overview of the NIDASH Family of Documents and suggestions to the neuroimaging community for implementing these standards to support data sharing activities, as well as in reporting issues or comments.

Introduction

This primer document provides information on the NIDM-Experiment specification. The goal of NIDM-Experiment is to provide terms that describe entities and activities for general scientific experiments with a focus on those specific to neuroscience. It is meant to work with NIDM-Workflow, which describes the processing and analysis of data and NIDM-Results that describes the results of workflows in the fMRI domain. It also provides terms used in PyNIDM, which can be used to annotate data.

Overview of the NIDM Experiment Component

This section provides an explanation of NIDM-Experiment, which is based on the W3C PROV ontology (Prov-O) that has as it basic elements Entities, Activities, and Agents. In constructing NIDM-Experiment, we have reused terms from existing terminologies and ontologies where possible. Terms that are reused from other ontologies are imported into the main NIDM-Experiment OWL file and can be found in the /imports directory. The most extensive modality coverage is for MRI, but there are also terms useful for electrophysiology experiments. Extensions to other modalities and expansions of existing modalities are ongoing and requests for the inclusion of terms for specific experiments are encouraged.

A MR imaging experiment modeled using NIDM-experiment.

NIDM-Experiment will be integrated into PyNIDM PyNIDMin the future. PyNIDM will include a mechanism by which users can search for terms necessary to annotate their specific dataset. It will also provide a mechanism by which users can request needed missing terms to be included in future NIDM-Experiment releases.
