Subject proposal
Date Wed, 09 Jun 2004 21:32:13 GMT
On the suggestion of Geir Magnusson and Rodney Waldhoff, I am sending this 
proposal to the incubator list to see if there is any interest for a new 
persistence project. At the moment I am not an ASF member and I am looking 
for others to join in on the project if there is interest. 

In a nutshell, it is not just an O/R mapper, but a generic persistence 
engine that can be used as an O/R mapping tool. It's current state of 
development is that it is in one production application already, but I am 
going through a bit of a refactor to the mapping stuff (it is amazing what 
a real application will bring to light!), and working on more unit tests 
as I progress in that area. It is far from complete and in the production 
application I am using essentially the bare bones of it so there is quite 
a bit of 'public' API to define and produce as well as more engine 
aspects. 

I have some of the documentation worked out, but it isn't complete and a 
tad bit fragmented, but the rationale is there as well as some of the 
configuration stuff so anyone should be able to get a good idea of what 
the intent is and what is currently happening. You can preview the docs 
at:

http://www.bull-enterprises.com/aom/persistence/index.html

It currently uses several Commons projects such as JXPath, Jexl, 
BeanUtils, Collections, etc., some of which is documented on the site I 
listed. If anyone is interested let me know, otherwise I'll have to resort 
to sourceforge.

As for my involvement with apache (if it helps/matters) I have made some 
relatively small contributions to Jelly and Jexl and have used most of the 
Jakarta stuff at one point or another for a few years. I also strongly 
envangelise the Jakarta stuff every chance I get. My current employer is 
on an open source kick right now where we use struts, tiles, logging, 
beanutils, a couple of the tag libraries and Jelly. 

With regards to persistence engine experience, this will be my 3rd go 
around. I built one for a company a few years ago and recently worked on a 
future commercial product which I rebuilt to run on top of Avalon 
(Excalibur then Fortress) and incorporated Jelly as well as several 
Commons projects.

If desired I can send diagrams, more info and even code.

Thanks,
Robert McIntosh
