There is some Echo...

The RSS/RDF folks have chosen a name for their format and TCK: Echo (no official birthday on the page, so let's say June 25, 2003). Unfortunately, there is another Echo, a Java framework for web applications, which went 1.0 on June 9, 2003. Two projects with the same name, with a real starting in the same month of the same year, both web oriented is really a bad thing (from a googling point of view).
