Dear all, I think that Niranjan's points are important, especially point 1. Coming from very large data repositories, I have found that PSHB still seems to think on the small scale, e.g. relatively small directed feeds. However, the world I work in, which is perfect for PSHB, is large and dynamic datasets. What my very diverse users want are feeds that they can filter. Now I am sceptical that metadata is the way forward here, but some form of subscriber-set filters would be essential when the feeds get very big.
