We are in the early stage of overhauling a multi-brand website built using a custom developed java mvc framework to enable web 2.0 features. Built-in features we are looking at are: i18n, sso, content search and indexing, personalization, mashup support, ajax support, rich media content storage and management support, friendly to search engine optimizations, bookmarkable URLs, support for social networking sites, support for page composition and decoration using templates.
A combination of these features are supported by many portal and cms software.
Any insights will be very helpful in using a portal/cms combination to address this requirements!
This is a follow-up on this post focusing on the portal/cms angle
