| - And I stopped writing code there because it's clearly going to get a lot more complex pretty quickly and it's time to solicit input. The rest of the idea for the UI is that when a user selects a variable by highlighting (single clicking on) the name in the data set tree the appropriate sub-setting interface appears in the Sub-setting Pane. By navigating the data set tree, clicking the check boxes, and highlighting the selected variables the user can build the data request that they want. |

| + James says: |

| + How about making the left panes work more like the mac's finder window. Suppose you started with a thredds catalog URL and got it's contents in the leftmost pane. Then click on an item such as a catalog and see that in the pane to the right. Suppose there were many catalogs in a nested hierarchy, the number of panes would be limited to say four, with the leftmost stuff rotating off to the left (and out of the display). Then you get to data and the thing that appears is the IFH in the pane to the right. |
| + |
| + I know that in your text on the wiki you talk about this, but I just wanted to say it too. |
| + |
| + The advantage of using the IFH is two fold: First, it can be customized and we can even install a Kepler version on a Kepler machine and use it to reference data sets/sources that are remote to it (the interface _is_ bundled with the server, but it can actually run on any machine on the network). So it's easy for us to tweak. Second, we can then direct effort to improve the IFH - a long-time goal of mine - and see benefits for all users, not just kepler users. Conversely, Kepler can also see benefits from improvements other projects make to the interface. |
| + |
| + We have not improved the interface at all since I wrote the initial version years ago (but it's widely used). I think this is largely because it's hard to update server-side code in a timely manor (although it's easier with Hyrax and we could think about/propose some innovative update techniques that are just too involved for me to get into here - I have seven minutes left before the telecon. The other reason is that I think most people want to make the 'killer app' and that's just not very often a data server... |
