>> OCaml is an industrial strength programming language supporting functional, imperative and object-oriented styles. It has in recent years seen a marked increase in development activity, particularly in the compiler itself , core libraries  and developer tools . Many of these newer libraries and features are already dependencies of a number of large upstream projects .

I see the OCaml SIG providing the current stable compiler (4.02.1 at time of writing), and a selection of useful libraries and developer tools. This could then be used as a basis for other applications or SIGs to build upon - for example, it would make CentOS a good platform for building Unikernels  and it would be helpful in getting the Xapi Project suite of daemons  into one of the virtualisation/cloud SIGs. We actually already have a number of specs that are built for CentOS 6 which could make a good starting point .

The reason I was thinking of a separate SIG is that a number of the
interested parties I listed don't care as much as I do about
virtualisation, and so a more general SIG seemed appropriate. Even
though here at Citrix our focus is virtualisation, of the ~120 SRPMs we
build for the XenServer buildroot project around 80 are entirely generic
OCaml libraries that may well be of use to other people outside of the
virtualisation area. An OCaml SIG would avoid muddying the waters by
including a large number of seemingly irrelevant RPMs in the Virt SIG.
