About the CLARIN Virtual Language Observatory

The Virtual Language Observatory (VLO) faceted browser was developed within CLARIN as a means to explore linguistic resources, services and tools available within CLARIN and related communities.

All information in the VLO faceted browser is based on the metadata descriptions of resources as provided by the parties (CLARIN centres) that host the original data. It gets refreshed regularly but may not be completely up-to-date with the current state of the original data and metadata depending on the date, time and state of the metadata providing/retrieval process (based on OAI-PMH).

See the list of contributors for an overview of CLARIN centres and other sources currently providing metadata to the VLO.

If you have questions or remarks concerning the VLO, please contact the maintainers by sending an e-mail to vlo@clarin.eu. Comments on individual metadata records can be submitted by using the "report" button () that can be found on every page with search results or record information.
