Licensing terms for data derived from ARB/SILVA data



Dear ARB/SILVA team,

I am writing to inquire about a special case regarding your data
licensing terms.
I am involved with the Debian Med project
(https://www.debian.org/devel/debian-med/), whose goal it is to provide
software from the medical and bioinformatics fields to users of the
Debian Linux distribution. Currently I am working on packaging a piece
of free (GPL) software for prediction of rRNA genes in sequences. This
software requires (and would be bundled with) a set of nucleotide
profile HMMs (built with HMMER) based on several individual data
sources. One of the data sources used to build these HMMs was the file
LSURef_115_tax_silva_full_align_trunc.fasta, available from your database.
Since your licensing terms
(http://www.arb-silva.de/silva-license-information/) are not clear about
how derivatives of your data are to be licensed, I would like to ask
whether it would be OK for us to package and redistribute these HMMs
under a free license, for both academic and non-academic users. I wish
to make it clear here that the original file
LSURef_115_tax_silva_full_align_trunc.fasta will NOT be included in the
package, only HMMs built from it (and other free sources).

I am looking forward to your response.

Best regards
Sascha Steinbiss
