property qualifiers

[lvaudor]

I think the way we're supposed to add property qualifiers is not intuitive. Indeed, we're supposed to put it that way:

stations_metro_Lyon=spq_init() %>% 
  spq_add("?station wdt:P16 wd:Q1552") %>%           # ?station is part of the Lyon metro network
  spq_add("?station p:P197 ?statement") %>%            
  spq_add("?statement ps:P197 ?adjacent") %>%       # ?station is connected to ?adjacent station 
  spq_add("?statement pq:P81 ?line") %>%                 # this connection is through line ?line
  spq_add("?statement pq:P5051 ?direction") %>%     # this connection is in direction ?direction
  spq_label("station", "adjacent", "line", "direction") %>% 
  spq_perform() 

For me, I'd assume that the "statement" IS a triple pattern, so that I'd like to put it that way:

stations_metro_Lyon=spq_init() %>% 
  spq_add("?station wdt:P16 wd:Q1552") %>%                      # ?station is part of the Lyon metro network
  spq_add(statement="?station wdt:P197 ?adjacent")  %>%  # ?station is connected to ?adjacent      
  spq_add("?statement pq:P81 ?line") %>%                           # this connection is through line ?line
  spq_add("?statement pq:P5051 ?direction") %>%               # this connection is in direction ?direction
  spq_label("station", "adjacent", "line", "direction") %>% 
  spq_perform() 

@maelle do you feel the way I do? Would that be possible without being too much of a hassle?

This is not a priority so I'll assign myself to this ;-)
