During the FAIR-EASE project, significant work was done to improve how researchers discover Earth science data. One key advancement was the use of the SpatioTemporal Asset Catalog (STAC) standard, which helps organise and describe geospatial data like satellite images in a consistent way. Originally developed for satellite data, the STAC specification allows users to search for data based on specific criteria, such as location and time.

By adopting STAC, the project made it easier to find relevant data quickly and accurately. FAIR-EASE also took advantage of existing tools like STAC Browser, PySTAC. In addition, efforts were made to align STAC with controlled vocabularies and PID systems (e.g. ROR) to improve the FAIRification data items (i.e. level 2 in comparison of data collection which is level 1)
