REDWOOD CITY, Calif., Apr. 8, 2010 - Versant Corporation (Nasdaq: VSNT) announced today that it will expand the open source licensing options for its db4o embedded database technology to include the top most popular FLOSS licenses as listed by the Open Source Initiative.
In 2007 db4o introduced its third licensing option dubbed dOCL (db4o Opensource Compatibility License) for free/open source projects that want to embed db4o but do not want to (or are not able to) license their derivative work under the GPL in its entirety. This opened the doors for db4o to be used in major open source projects like Novell's Mono, Redhat's Fedora-Linux, Eclipse (Apogee), Spring, JPOX, Apache-Lucene (Gdata), RSSOwl newsreader, Arum DataEye and Funambol (SyncML). In order to further increase adoption of db4o in the open source ecosystem the original list of licenses is now being expanded to include the Microsoft Public License (Ms-PL), Microsoft Reciprocal License (Ms-RL) and Code Project Open 1.02 License, broadening the scope of the dOCL to now cover the top most popular FLOSS licenses.
"We really want to tear down any walls preventing open source projects from incorporating our cutting-edge object database technology. All developers should experience first-hand, how much time and code they can save by using a native object persistence solution rather than tedious object-relational mapping" says German Viscuso who manages db4o's growing community of 75,000 registered developers. "Even though we rely on a dual licensing scheme (where db4o is also commercially licensed in proprietary software) we believe we've found an excellent balance to broaden adoption and serve the best of both worlds. We recently moved to GPLv3 and now with the addition of the Ms-PL and CPOL to our dOCL we estimate db4o could potentially be used in 94% of existing Java and .NET open source projects".
