Support for alternative databases / Fork a BerkeleyDB-free version #4

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I wanted to note that although 'jwktl' is covered by an Apache license, it has 
a deep dependency on Berkeley DB. Oracle dual licenses Berkeley DB; its open 
source license is now AGPL (see e.g. 
http://www.infoworld.com/d/open-source-software/oracle-switches-berkeley-db-lice
nse-222097)  This makes it impractical to use jwktl in any commercial 
application, unless a very costly commercial license (on a per-processor basis) 
is acquired from Oracle.

I have not dug into the source code yet, but I would like to have some informed 
opinion on the feasibility of moving from using Berkeley DB to a more open 
licensed database system - either purely relational such as the excellent H2, 
or the powerful XML database system BaseX.

The "deep dependency" is known and explicitly mentioned on the homepage. I'm 
not an expert in licensing models, but I have been told that releasing JWKTL 
under the Apache license is OK also with the Berkeley DB dependancy, as long as 
this is made clear. As such, I don't see a contradictory licensing.

Regarding your issue of using JWKTL for a commercial application: it is well 
possible that the Oracle dependency does not allow this; I don't know exactly.

Switching to a different database is well possible and there are some first 
steps towards supporting multiple databases already in the code. However, 
there's no quick solution to that. I suggest keeping this ticket under the 
heading of adding support for a different database and maybe splitting the 
licenses for API and database.

I'd also like to see the support of other databases, as using BerkleyDB with 
Android is kind of a mess
