Standardizing the names of entities

[Luis Capelo]

Hi all, 

I noticed that from v0 to v1 the names of entities changed from singular (job, report, ...) to plural (jobs, reports, ...). However, training remained the same, in singular in v1. It would be nice to have them all in plural. :-) 

Best,

Hello Luis,

Training is a quirky word, despite not having the "s" it's use is intended as plural here, in the sense of training almost categorically. The consistency might be nice, will see if there's a consideration on how it's used in the API vs. other language around Training on ReliefWeb.
