Source Code for Package gavo.svcs

 1  """ 
 2  Services, cores, and support. 
 3   
 4  A Service is something that receives some sort of structured data (typically, 
 5  a nevow context), processes it into input data using a grammar (default is 
 6  the ContextGrammar), pipes it through a core to receive a data set and 
 7  optionally tinkers with that data set. 
 8   
 9  A core receives a data set, processes it, and returns another data set. 
10   
11  Support code is in common.  Most importantly, this is QueryMeta, a data 
12  structure carrying lots of information on the query being processed.
