The International Aid Transparency Initiative (IATI) is a global initiative aimed at improving the transparency of development and humanitarian resources and their results to address poverty and crises. Organizations publish data in line with the IATI Standard, and this data is freely available to the public. The initiative provides resources, tools, and guidance for publishing and accessing IATI data.
INTERMAGNET is a global network of cooperating digital magnetic observatories that monitor the Earth's magnetic field. The site provides data and information from geomagnetic observatories worldwide, including data downloads, plots, formats and quality checking. The programme seeks to promote modern standards for measuring and recording the Earth's magnetic field and to aid in establishing new observatories or upgrading existing ones.

IPUMS International is a project that collects and distributes census microdata from around the world. Its goals are to preserve data and documentation, harmonize data, and disseminate the harmonized data free of charge. The project covers 104 countries and 656 censuses and surveys, providing source data supplied by participating National Statistical Offices.
The Integrated Interactions Database (IID) is a resource for protein-protein interaction (PPI) data. It allows users to submit up to 1000 protein identifiers, including gene symbols, UniProt IDs, and Entrez Gene IDs, along with the source organism, to retrieve PPIs. Users can filter results by evidence source, including experimental and predicted data, and set minimum thresholds for experimental evidence. Retrieved results can be downloaded.

INTEGRAL was an ESA mission with US and Russian participation whose instruments covered the hard X-ray and gamma-ray energy range. It provided wide-angle, time-resolved imaging in gamma-ray, X-ray, and visual light, broadband spectroscopy, and all-sky detection of transients. Its data are available through the INTEGRAL Science Legacy Archive and the Off-line Scientific Analysis software in ESA Datalabs.
The institutional Repository of IMDEA Nanociencia is a digital archive collecting the institute's scientific production to preserve and disseminate research results in open access. It covers academic activities, institutional documents and research, and is harvested by external services.

INPTDAT is a data platform for plasma technology provided by the Leibniz Institute for Plasma Science and Technology. It offers access to research data and information from fields of applied plasma physics and plasma medicine, aiming to support findability, accessibility, interoperability and re-use of data for the low-temperature plasma physics community.
InnateDB is a publicly available database of genes, proteins, experimentally verified interactions and signaling pathways involved in the innate immune response of humans, mice and bovines to microbial infection. It integrates interactions and pathways from major public databases with manually curated data, and offers pathway, Gene Ontology and network analysis tools.
The INGV Open Data Portal provides public access to metadata from the institutional Data Registry of the Istituto Nazionale di Geofisica e Vulcanologia, covering research data in seismology, volcanology and environment. Data are attributed to their authors and can be searched by keyword or by drawing an area on a map; datasets are listed by availability of web services for programmatic access.
