What do “branch”, “tag” and “trunk” mean in Subversion repositories?

Question

I\'ve seen these words a lot around Subversion (and I guess general repository) discussions.
I have been using SVN for my projects for the last few year

Answer 1

I think that some of the confusion comes from the difference between the concept of a tag and the implementation in SVN. To SVN a tag is a branch which is a copy. Modifying tags is considered wrong and in fact tools like TortoiseSVN will warn you if you attempt to modify anything with ../tags/.. in the path.
