Another recent piece of good news about Idealist, which is buried deep in the comments on one of my earlier Blog entries on Idealist, is that someone is actively working on an open source replacement for it. The first alpha release was posted on the web a couple of days ago (here). Its developer says:
Unlike Idealist, it has 'field' buttons (to the left of each field, support for WWW and DOI addresses, and uses colour. Also, record and field definitions are saved in each database, which I think is an improvement over the idealist way of doing things. I developed it on Kubuntu Lucid Linux. It should run on Windows, although several other packages will have to be downloaded and installed. A Windows exe is not yet available so it must be run as a Python script. Searching by integer, float, record-number and date are implemented, but as yet word/phrase searching is not.
Fortunately there are some open source text indexing engines already available (e.g. Xapian) that can be used. Progress is quite slow and so I'm still hoping to find some 'helpers' - particularly with some of the more advanced programming. Also, the project needs a more distinctive name (suggestions welcome).By the way, if you want to try out the original, you can download version 3 of Idealist from here.
