 EuroGEOSS Open Source Metadata Editor Published!

The European Open Source Metadata Editor (EUOSME) is a web application to create INSPIRE-compliant metadata in any of 22 European languages. It has been developed by the Joint Research Centre as part of the EuroGEOSS project ( It is therefore a research outcome and not a production tool.


EUOSME can be accessed through the INSPIRE Geoportal


The EUOSME User Guide can be found at:


The EUOSME Developers’ Guide can be found at:

EUOSME follows the European Union Public Licence. See


EUOSME is written in Java and based on Google Web Toolkit (GWT) libraries. EUOSME has been developed to help create metadata compliant with the INSPIRE Directive (2007/2/EC) and the INSPIRE Metadata Regulation (1205/2008) (see


EUOSME allows to describe a spatial data set, a spatial data set series or a spatial data service so that the metadata is also compliant with the standards ISO 19115:2003 (corrigendum 2003/Cor.1:2006)  and ISO 19119:2005. It is therefore an implementation of the INSPIRE Metadata Technical Guidelines based on these two ISO standards, and published on the INSPIRE web site. This editor builds on the experience acquired in the development of the INSPIRE Metadata Implementing Rules, and includes the INSPIRE Metadata Validator Service available from the INSPIRE EU Geo-portal (


This editor focuses on discovery metadata, and in particular on the fields identified by the INSPIRE Directive of the European Union (2007/2/EC). The Users’ Guide and Developers’ Guide of EUOSME allow to extend the editor to describe in greater detail information resources for purposes of evaluation and use and to satisfy the needs of different user communities. The editor will be extended to support the implementation of the Data Sharing Principles of the Group for Earth Observation System of Systems (GEOSS). 


The Editor is provided on an “as is” basis and it is now up to the community of users to contribute to its further development, and share this work through OSOR for the benefit of all users. Please share your technical questions and answers through the dedicated metadata discussion group on the INSPIRE Forum
