I am aware of two projects undertaken with Magma that are running in a corporate "production" environment. I know there are other significant projects but not necessarily in "production".

I myself am not at liberty to discuss them, but I've linked a new "Magma Projects" page from the home page with a couple of publicly announced projects which I hope their owners and other projects owners will add their entry to the page, that this question may be clarified.

Thanks.

Are there apps in production (not necessarily mega-high volume) that use Magma? Is there a list of these someplace?

Thanks - Sophie

Can you expand on what you mean about the "non standard" part?

Yes, Gjallar is in production today for one customer. They may be expanding it a bit. This is a low volume deployment though. We also have one more customer lined up and interested in a highly customized version.

Gjallar uses Magma with a relatively complex model. The architecture around transactions is "non standard" though so one should not use Gjallar as a "typical" example of a Magma app.

Oh yes, you're talking about that Command framework you have. I am very interested in taking a look at that. Is it separable from Gjaller for use in other apps?

Yes, what I mean is that in Gjallar we have reified all our kinds of database modifications. This means we have a class hierarchy subclassing Q2Txn (Q2 = Gjallar prefix), for example there is a Q2CaseCreateTxn.

So when we create a case in Gjallar we don't do (silly pseudo code coming up) as one would typically do:

session begin. allCases add: aNewCase. session commit.

Instead we do a much more elaborate operation kinda like:

session begin. txn := Q2CaseCreateTxn new. txn subject: 'blabla'; description: 'more text'. "etc etc" txn apply. "this does mainly the same thing as the typical code above" allTransactionsSinceDawnOfTime add: txn. session commit.

...but in a much more elaborate, convoluted way of course only in order to make it really hard for a Gjallar newbie to understand what the heck is going on and thus make the wrong conclusion that using Magma is complicated. :) :)
