Hi Martijn. Thanks for the link to Narval. I was not aware of it. There seem to be many similarities between Narval and Piper, for instance, the use of existing resources on the Internet and a way to graphically connect these resources. However, it seems Narval is primarily an agent system, meaning there is a "software agent" that goes out on the Internet looking for things of interest to the user. Piper, on the other hand, is primarily a data flow system, meaning the user knows what s/he wants, connects the appropriate resources, and then starts the flow of data. It is possible that Piper can use agents in the future, but that is well into the future, since we have some very difficult tasks still to accomplish. I don't know if Narval would like to collaborate on this, but it seems they have their goal already very well defined. Cheers.
