Wikipedia says "Web 2.0 refers to a perceived second generation of web-based communities and hosted services — such as social-networking sites and wikis — which aim to facilitate collaboration and sharing between users.
Technologies such as weblogs, social bookmarking, wikis, podcasts, RSS feeds (and other forms of many-to-many publishing), social software, web application programming interfaces (APIs), and online web services such as eBay and Gmail provide a significant enhancement over read-only websites."
My personal view is that the key word is 'mash-up' which is missing from the Wikipedia definition.
The intention in creating this Data Model is to identfy all the various Components and show they would be related in an ERD.
This, in turn, will form the basis for an all-embracing Data Dictionary.
