There are indeed issues with searching if people aren’t using matching descriptions. Think of someone calling a collection of texts a “text collection”, while someone else might be searching for a “(text) corpus”. A pers… --- ## [What is metadata?](https://forum.clarin.eu/t/what-is-metadata/456)

Good question. In fact, there is no such thing as a single CLARIN metadata scheme. Practice showed that using a single scheme for a large community (e.g. the Humanities) often results in a mismatch between the chosen ele… --- ## [If there is no single metadata scheme, how should I describe my resources in order for them to be compatible with the CLARIN infrastructure?](https://forum.clarin.eu/t/if-there-is-no-single-metadata-scheme-how-should-i-describe-my-resources-in-order-for-them-to-be-compatible-with-the-clarin-infrastructure/453)

CLARIN proposes a component-based approach: you can combine several metadata components (sets of metadata elements) into a self-defined scheme that suits your particular needs.
