Subject: Re: [galaxy-dev] filtering a <param> of type 'data' so only one
type is available
Glad it worked and thanks for pointing out a more general mimetype - does any one else
(other than me) want to vote to add
<datatype extension="rda" type="galaxy.datatypes.binary:Binary
mimetype="application/x-gzip" subclass="True" />
to datatypes_conf.xml.sample permanently ?

Using format="rda" will restrict the list to history items of the
datatype - but ONLY if the rda datatype has been defined!
The easiest way to do that is to define a new datatype in datatypes_conf.xml
and since rData is binary, you should subclass binary.
Something like (untested - especially the mimetype !)
<datatype extension="rda" type="galaxy.datatypes.binary:Binary"
mimetype="application/x-rlang-transport" subclass="True" />
might work. A server restart is always required to load any new datatypes.
It works! I changed the mime type to application/x-gzip, since
serialized R objects are gzipped.
