Metadata Harvesters

When we register DOIs at Journal of Linguistic Association of Nigeria (JOLAN) the information about research outputs and activities is made openly available for indexing in downstream services. These services reuse DataCite DOI metadata to facilitate research discovery, analysis, and tracking. This broad adoption highlights the value of high-quality, consistent metadata in connecting research outputs and resources.

What is Metadata Harvesting?
Harvesting metadata refers to the automated process of collecting and aggregating metadata records from the DataCite Metadata Store. This can be done using protocols such as OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) or APIs.

This process allows external services, research institutions, and data discovery platforms to access structured information about research outputs, including datasets, software, and many more. By harvesting metadata, organizations integrate DataCite metadata into global research infrastructures.

Who can harvest DataCite metadata?
All DataCite metadata is openly available with a CC0 license, meaning it is available to everyone. The DataCite Metadata Store includes all DOIs and deposited metadata in our database and to the extent possible under law, DataCite e.V. has waived all copyright and related or neighboring rights.
