A mashups time? Welcome to Enterprise Mashup world
Depending upon where mashups take place, one can classify them as client or server side mashups. Oracle’s WebCenter is in the first category based on portal standards while QEDWiki from IBM is in later.
Many free as well as commercial and online as well as development tools are coming up so that mashups can be easily built. Some of them are listed here:
Rex from Nexaweb
QEDWiki from IBM
Many startups also rushing in to cash on this coming up with their products based on mashups. We should see more innovation and hits&miss in this field.
Anyway, if you come across good mashup tools let me know.
