As I understand and so far I have been reading about this, sitemaps would only show pages and relations between them. An architectural blueprint would show pages, pages components and relationships between them and well...task flows would show the flows among a certain task.
Are these three definitions correct?
And do you have maybe an example of an architectural blueprint? I do not quite understand the difference and the importance on having a sitemap and a blueprint. Are both necessary for the deliverables to the client?
