OPTIMETA – Strengthening the Open Access publishing system through open citations and spatiotemporal metadata

The OPTIMETA project is dedicated to strengthening the open access (OA) publishing system by integrating open citations and spatiotemporal metadata from OA journals into openly accessible data sources. In this way, we contribute to open research information and ensure better discoverability and thus visibility of OA publications. This in turn improves the attractiveness of OA journals as publication venues.

The funding period of the project OPTIMETA ended in summer 2023.

Our objectives:

  • Development of two plugins for Open Journal Systems (OJS) for the collection and transmission of geodata and citation data (geoplugin and citation plugin)
  • Promoting the networking of scientific articles and their metadata by connecting the plugins to open data sources.

In order to be able to implement the plug-ins in a user-centered manner, the development is based on a needs analysis in which the requirements for the plug-ins are formulated together with editors or operators of OA journals on the one hand and researchers on the other.

OPTIMETA is carried out by the TIB – Leibniz Information Centre for Science and Technology and the Spatio-temporal Modelling Lab at the Institute for Geoinformatics at the Westfälischen Wilhelms-Universität Münster (WWU)  together with our partners:
