Hi all . Just thought I'd mention another open-source project which is using pipelining (somewhat similarly to Piper). This is the package called "Blue Orca" - http://pyrite.cfas.washington.edu/orca/ . This is a Java-based package. A brief quote from its website - " The Orca Framework separates different aspects of data processing and rendering into segments of a pipeline. " This project seems to emphasize data visualisation more than the pipelining side of things, but anyway - it may be a useful resource for ideas! Looks like a very nice package .... -------------- next part -------------- An HTML attachment was scrubbed...
