-====== Metadata Licenses at UFZ ======
-===== Background =====
-At UFZ, spatial research data are managed and published through the spatial data infrastructure **spatial.IO**
-(https://zenodo.org/records/17347355).
-Within spatial.IO, **GeoNetwork** (https://geonetwork-opensource.org/) is used as the central system for metadata cataloging and for assigning DOIs to datasets.
-As part of improving interoperability, the UFZ GeoNetwork was registered for metadata harvesting, specifically for the **Ocean Data and Information System (ODIS)**
-(https://odis.org/).
-===== The Licensing Challenge =====
-During the registration and harvesting process, it became apparent that while the **datasets themselves** were already assigned licenses for data reuse, the **metadata records** lacked an independent and clearly defined license.
-This raised an important question:
-How should UFZ metadata be licensed, both within the GeoNetwork and in a broader institutional context?
-===== Internal Consultation =====
-The issue was discussed within the UFZ Research Data Management (RDM) team. Two main options were considered:
-==== CC0 (Public Domain Dedication) ====
-  * Enables unrestricted reuse of metadata
-  * Facilitates harvesting by machines, crawlers, and aggregators
-  * Reduces legal barriers for reuse and redistribution
-==== CC-BY (Attribution Required) ====
-  * Ensures attribution to UFZ
-  * Maintains visibility and credit for the metadata creators
-===== Orientation Towards Established Infrastructures =====
-To support the decision-making process, UFZ aligned its approach with established data infrastructures, including:
-  * **PANGAEA** (https://www.pangaea.de/)
-  * **Europeana** (https://www.europeana.eu/en)
-In particular, Europeana's detailed explanation of metadata licensing was highly influential:
-https://www.europeana.eu/en/rights/usage-guidelines-for-metadata
-===== Decision and Implementation =====
-UFZ decided to apply the **CC0 license** to its metadata.
-This approach maximizes openness and technical reuse, especially for metadata harvesting and aggregation. At the same time, UFZ explicitly **requests appropriate attribution**, even though it is not legally required under CC0.
-In practice:
-  * Metadata in the UFZ GeoNetwork are published under **CC0**
-  * Users are asked to credit UFZ in an appropriate manner when reusing metadata
-  * Information about the license and attribution request is clearly documented within GeoNetwork
-===== Communication and Adoption =====
-All data holders contributing to the UFZ GeoNetwork were informed about this change. The applied license and the request for attribution were made transparent directly within the metadata records.
-===== Recommendation =====
-We recommend that other research centres and data infrastructures consider a similar approach-using CC0 for metadata while encouraging attribution-wherever this aligns with their institutional goals and legal frameworks.
