Virtual Observatory data center publishing suite

 The Data Center Helper Suite (DaCHS) is a collection of Python modules
 (with some exceptions) to help you in setting up and running a VO-compliant
 data center. Moreover, some parts of this code are useful for client-side
 applications.
 .
 Currently, DaCHS supports most DAL protocols (SIAP, SCS, TAP), form-based
 interfaces, a publishing registry, ADQL and some other (less prominent)
 VO standards, and data management for various kinds of input.
