I posted a comment regarding Zope on photo.net, and got a comment back from Philip. He agreed with all of the good points I made about Zope, and added, in his words, "Zope is a noble effort, probably the only real competition to ACS". As far as differences between the two goes, there are many at the technical level. Philip's opinion was that ACS is easier for people to understand who have a background in RDBMSs, and I tend to agree. So, take that as you will. In my opinion, it's the same addage as always, "Use the right tool for the job." --Jeff --- Jeff K.
