To avoid confusion I usually refer these as "match block pipelines" or simply "match-pipelines". I think there needs to be a standard way to refer to these, because quite often one wants to discuss the actuall match block rather than the whole pipeline. > > >- the chain of components that produce the response (generator, > >transformers, and serializer). > > > >So I propose to change the name of <map:pipeline> in the > ><map:components> part to remove this confusion (also, what about > >document validation ?) > > > >What about > >- <map:pipeline-handler> > >- <map:pipeline-manager> > >- <map:pipeline-runner> > > > I don't like it, because all the names in the sitemap currently follow > the pattern: > transformer (noun) - transform (verb) > > Ideally, we need noun-verb pair for pipeline... > we could change <map:pipeline> to <map:pipe>, which would arguably conform to the noun - verb convention.
