---++ Features

!VODataService defines the follow extensions of the generic Resource type:
   * =DataCollection=:  describes a collection of data which can include a mix of images, catalogs, spectra and any other type of data.   A collection description may include a description of coverage on the sky and in time and frequency, and it may include a description of the component catalogs.
   * =DataService=:  This is an extension of the Service Resource type that represents a service that provides access to data.  One can describe the data's coverage on the sky and in time and frequency and its association with facilities and instruments.  
   * =CatalogService=:  This is an extension of the =DataService= type to describe a service that provides access to data, and specifically interacts with or returns information in a tabular form.  In addition to the =DataService= metadata, one may also describe the strucuture of the tables.
   * =STCStandard=:  This resource extension is used to define standard coordinate systems using STC.

It also defines an extension of the generic Interface type:
   * =ParamHTTP=:  this describes a service interface in the form an HTTP Get URL and comprised of a base URL and a set of arguments made up of key=value parameters.  In this extension, it is possible to describe the input parameters supported by the service.
