Just to be sure we talk about the same thing in the last couple of comments:

The aim of the author and tag specific pages is to appear under the URL:

• in.relation.to/emmanuel
• in.relation.to/hibernate-ogm

but right now we have

• in.relation.to/author/emmanuel
• in.relation.to/tag/hibernate-ogm

Personally I have no strong preference, but if the aim is to not display 'author' and 'tag' in the URL we need to look at this. AFAIU the URLs are (at least) partly driven by the directory layout. I am not sure whether we ever had something in place which would change that. I for my part don't remember such a thing.
