GAVO's Data Center Helper Suite is a collection of (primarily) python modules to help you in setting up and running a VO-compliant data center; some parts of this code are useful for client-side applications, too. All parts of DaCHS are GPLed Free Software.
Currently, DaCHS supports:
Support for further protocols (e.g., VOSpace) will come as required – by us or by you. Talk to us about your VO publishing needs (as well as what we dream of in terms of contributed code).
GAVO DaCHS should run on POSIX systems supported by our dependencies.
However, you are advised to set up a Debian machine to run it. For this,
you can add our repository and install the
gavodachs-server package (or
for just the code).
For other systems, you can use a tar ball, but expect having to do a little manual work. In particular, peruse the installation guide up front and get in touch with us. If you want to participate in the development of DaCHS, you are welcome to check out the source from our subversion repository.
To see DaCHS in action, check the GAVO data center.
More information, in particular on the non-trivial installation, can be found on our documentation page.
Finally, if you run DaCHS, you are strongly encouraged to subscribe to our dachs-users mailing list; this has been really low-volume so far (about one mail per quarter), but you'll get to be notified of any major changes that might affect your services after an upgrade.
