Rfam is a collection of non-coding RNA families represented by manually curated sequence alignments, consensus secondary structures, and predicted homologues.
Rfam is freely available under the Creative Commons Zero (“CC0”) licence.
We choose CC0 because:
It is the best way to encourage remixing and reuse as it makes clear to any user – academic, commercial or otherwise – that the data are not owned by anyone and therefore can be used freely.
It saves researchers time when reusing the data, which speeds up the process of science.
