Re: [science-iwg] Debrief Maritime Analysis Workbench

Ian,

In a nutshell, Triquetrum is the RCP UI for Ptolemy 2. We have collaborated with Isencia and to a less direct extend with the guys at Berkeley in the past to get a workflow engine into DAWN. You can think of DAWN as a would-be user of Triquetrum. The bits we do which are not done by Triquetrum are detailed in the tutorial which was attached, basically n-Dimensional mathematics and plotting in various dimensions including a large array of plotting tools.

Best Regards,

Matt

Hi there Matt,
thanks for that advice - the tutorial is a good first step to becoming familiar with both DAWN & it's general perspective on data analysis.
I'll work through the tutorial in coming weeks.

For a complete newbie, there seems a large overlap between DAWN and Triquetrum. Both appear to have ETL (extract, transform, load) capabilities similar to the Talend and Kettle applications I'm more familiar with, though maybe Triquetrum has deeper support for simulation & modelling.

As someone who has spent longer in the space, are you able to highlight any strategic differences between DAWN & Triquetrum?

Oh, without wanting to ignite a flame war, obviously anybody else's perspective on that is quite welcome too ;-)

[I know Triquetrum is a new project, but I see it's sitting on quite mature foundations.]

Cheers,
Ian
