Participation in the ROMS/TOMS User Forum and access to any
available technical support is limited to registered users.
We ask that users make appropriate acknowledgement of
The ROMS/TOMS Group, individual developers, participating
agencies and institutions, and funding agencies. One way to
do this is to cite one or more of the relevant publications
We describe "The ROMS/TOMS Group" as follows:
ROMS: Regional Ocean Modeling System
TOMS: Terrain-following Ocean Modeling System
The ROMS/TOMS Group consists of the scientists, engineers, and
the members of various academic institutes, government agencies,
and the general public that have contributed to the development
of the ROMS/TOMS Framework and agree to the terms of the MIT/X
license under which ROMS/TOMS is distributed.
Contributions of source code or documentation to the ROMS/TOMS
Framework implies that (unless explicitly noted otherwise) the
author cedes copyright of that material to the ROMS/TOMS Group
and accepts the terms of the license.
Membership in The ROMS/TOMS group is conferred to all who
contribute Software to the ROMS/TOMS Framework, and implies
acceptance of the copyright and terms of the license.
We have gone to considerable efforts to make this release flexible in
a way that a user tailors the standard source code for a given
application, while simultaneously bringing the central code under
svn source code management.
The new structure of ROMS allows user specific CPP definitions and analytical
options to be set in a small number of separate standalone header files.
Therefore, users no longer have to modify small blocks of code in one
long file like was neccessary in previous versions of
makes it easy to distribute the configuration for a specific
application via a small number of source code related files plus the
inputs (grid, forcing netcdf files), while allowing users of the
application to keep current with central code improvements via
also takes care of all licensing issues. You are free to
include your own statement of your contributions in the files you
distribute. The license and copyright statements by
the ROMS developer group remain in the source code distributed at
There are 3 ways a user can operate:
Method A (preferred): Work with a local source code that
is regularly updated with the official version at the www.myroms.org
svn repository using
svn update. This will allow bug
fixes and new code developments to be pushed out to users and
minimize the risk of a user unwittingly working with code with
More exotic adaptations to the code are best
maintained by local use of svn, so that possible conflicts
with the central svn repository can be reconciled when they
arise during the update process. (For example, if you give
us feedback regarding a bug, and we fix it in a slightly
different way than you did, you don't want that
to cause trouble when you update - svn helps with this).
Installing and using svn is not a big task and
users already have
to install perl, netcdf, mpi and their compilers, so it's not
a big additional step.
Method B: Users take a tagged release from our repository
and hack at it for their own means, but no longer apply updates.
Using this method the user risks living with bugs that are
or having to make ad hoc bug fixes themselves on the basis of
notices posted on the forum and/or diffs to individual
subroutines. We can name many drawbacks to this approach but
acknowledge that some users will go this route, and the MIT
License does not prevent them from doing so. The license even
technically allows them to pass malformed code along to others
though you can be sure it will expose the distributor to quiet
vilification among other ROMS users and developers.
Method C (Not good): We would like to strongly discourage
groups from distributing the full ROMS source code tailored to
user specific applications, even with the intention that the
code not be subsequently modified. This will allow bugs to
persist and even propagate, and denies users who adopt an
application from someone else the opportunity to take full
advantage of participation in the ROMS user community.
