Finally there is an LGPL C client library for MariaDB, and thus also for MySQL. Monty Program and SkySQL have been working on this for some time. Admittedly there was already the BSD licensed Drizzle client library which was also able to talk to a MySQL/MariaDB server, however its API is different. The C client library for MariaDB has exactly the same API existing applications are used to, so you can just re-link and keep going! There is also a new LGPL Java client library for MariaDB.

In case you don’t quite realise: this is actually a major thing.

At MySQL AB, the client library was made GPL and this flowed through to Sun Microsystems and then Oracle Corp. This licensing

The reason we are confident that the comparative decline in the use of the GNU GPL family of licenses and the increasing significance of complementary vendors in relation to funding for open source software-related vendors will continue is due to the analysis of our database of more than 400 open source software-related vendors, past and present.

We previously used the database to analyze the engagement of vendors with open source projects for our Control and Community report, plotting the strategies used by the vendors against the year in which they first began to engage with open

One of the favourite blog topics on CAOS Theory blog over the years has been our quarterly and annual updates on venture capital funding for open source-related businesses, based on our database of over 600 funding deals since January 1997 involving nearly 250 companies, and over $4.8bn.

There are still a few days left for funding deals to be announced in 2011 but it is already clear that 2011 will be a record year. $672.8m has been invested in open source-related vendors in 2011, according to our preliminary figures, an increase of over 48% on 2010, and the highest total amount invested in any year, beating the previous best of $623.6m, raised in 2006.

Oracle last week quietely announced the addition of new extended capabilities in MySQL Enterprise Edition, confirming the adoption of the open core licensing strategy, as we reported last November.

The news was both welcomed and derided. Rather than re-hashing previous arguments about open core licensing, what interests me more about the move is how it illustrates the different strategies adopted by Sun and Oracle for driving revenue from MySQL, and how a single project can be used to describe most of the major strategies from

While Oracle deserves some praise for its donation of OpenOffice.org code to the Apache Foundation, it is disappointing again to see a legitimate open source market contender that has been marginalized by miscommunication and mismanagement of the project by a large vendor.

OpenOffice.org, warts and all, was probably the most significant competition for Microsoft Office for years and in many ways demonstrated the advantages of open source, helping usher in wider use of it, as well as greater usability. OO.o was in fact my reason for originally investigating and moving to open source software more than a decade ago. Regardless of past mismanagement of community and technology, that competitive factor has been diminished greatly since Oracle took ownership of

Bradley M Kuhn published an interest blog post at the weekend explaining why he believes Canonical is about to go down the open core licensing route and heavily criticising the company for doing so.

My take on the post is that it is the worst kind of Daily Mail-esque fear mongering and innuendo. Not only does Bradley lack any evidence for his claim, the evidence he presents completely undermines his argument and distracts attention from what could be a very important point about copyright assignment.

The premise? Mark Shuttleworth has admitted that he plans to follow the open core licensing strategy with Canonical.

The evidence? Mark praises the strategy Trolltech took of selling proprietary licenses.

The problem? Trolltech did not follow the open core licensing strategy. Neither

Stephen O’Grady and Simon Phipps have both recently published interesting posts on the current state of open source, with Stephen pondering the relative growth of open source and Simon wondering whether the “commercial open source” bubble has burst.

What they are describing, I believe, is the culmination of the trends we predicted at the beginning of 2009 for commercial open source business strategies – specifically the arrival of the fourth stage of commercial open source.

What is the fourth stage of commercial open source? In short: a return to a

In my time at MySQL AB in the Community Relations possition (2004-2006) I wrote several articles on MySQL’s licensing for the MySQL web site. The core reason for having to explain anything was (and still is) the dual licensing of MySQL, in particular the client library. I left MySQL AB years ago, but people still ask me licensing questions. Below is an excerpt from one such question, and my response.

If the recent debate about open core licensing has proven one thing, it is that the issue of combining proprietary and open source code continues to be a controversial one.

It ought to be simple: either the software meets the Open Source Definition or it does not. But it is not always easy to tell what license is being used, and in the case of software being delivered as a service, does it matter anyway?

The ability to deliver software as a hosted service enables some companies that are claimed to be 100% open source to offer customers software for which the source code is not available. Coincidentally, James Dixon has this week highlighted

There’s been a fair amount of attention – both positive and negative – on dual licensing in recent weeks. A few days ago Brian Aker wrote: “The fact is, there are few, and growing fewer, opportunities to make money on dual licensing.”

It is a sweeping statement, but one that is worth further consideration, especially since, as Stephen O’Grady noted it is directly contradicted by Gartner’s prediction that: “By 2012, at least 70% of the revenue from commercial OSS will come from vendor-centric projects with dual-license business models.”

Success?

I remember reading this

One of the issues I have with the Free Software approach is that advocates have habit of throwing the baby out with the bathwater when discussing issues that they see as in any way negative to free software.

I was reminded of this while reading Bradley M. Kuhn’s criticism of Mark Shuttleworth’s reported views on copyright assignment.

Having read the original interview with Mark, and then Bradley’s response, it is pretty clear that the two have very different perspectives on copyright assignment: Mark is speaking from the perspective of a commercial business, Bradley form that of a non-profit foundation.

The two entities have very different

We’re continuing to see signs that the dominant GPL open source license may be fading from favor among commercial open source software players. The latest move away from the GPL comes from content management software vendor Alfresco, which is moving to the LGPL after originally releasing its code under the GPL three years ago. The reasoning for the shift, according to Alfresco CEO John Newton, is the company sees greater opportunity beyond being a software application, particularly given the emergence of the Content Management Interoperability Services standard. Alfresco won mostly praise for its move, and it does make sense given where open source is going these days.

Since the European Commission announced it was opening an in-depth investigation into the proposed takeover of Sun Microsystems by Oracle with a focus on MySQL there has been no shortage of opinion written about Oracle’s impending ownership of MySQL and its impact on MySQL users and commercial partners, as well as MySQL’s business model, dual licensing and the GPL.

In order to try and bring some order to the conversation, we have brought together some of the most referenced blog posts and news stories in chronological order.

Part one took us from the announcement of the EC’s in-depth investigation up to the eve of the communication of the EC’s Statement of Objections.

A new round of GPL-based BusyBox suits has been filed, targeting big names in electronics and IT. We’ve long covered these series of GPL-based suits and settlements, but this latest round comes at an interesting time for open source software and its licensing.

First, we have the backdrop of the Oracle-Sun-MySQL acquisition, with opponents arguing to the world and the European Commission, which is reviewing the proposed merger before approving it, in part that the GPL is, ironically, granting too much power to its user, in this case Oracle. I’ve been quoted in the press and honestly

Oracle’s proposed acquisition of Sun Microsystems looks set for approval by the European Commission after the competition commission welcomed commitments from Oracle related to the future development and licensing of the open source MySQL database.

The EC has until January 27, 2010, to reach a final decision however it appears that significant progress has been made following hearings in Brussels last week where Oracle made its case for approving the acquisition and opponents including SAP, Microsoft and Monty Program AB argued against the proposed acquisition.

Oracle has published a list of ten commitments that it is prepared to make to assuage the EC’s concerns over the future of MySQL, which were quickly and enthusiastically welcomed by the European

Matt Asay is right, in my opinion, to point out the inherent bias in the case Monty Widenius et al have made against Oracle’s potential ownership of MySQL. I would go further, however, in stating that the case being made against Oracle is flawed by the fact that it is so self-serving. For instance:

• I previously noted that the Widenius/Mueller case against Oracle owning Sun/MySQL is entirely dependent on the theory that Oracle will not invest in the ongoing development of MySQL, which is something it has publicly committed to doing.

• The case against Oracle owning Sun is also based on the theory that

Everyone seems to have an opinion about whether Oracle should be allowed to acquire the MySQL database along with Sun Microsystems including former MySQL/Sun executives, developers, rivals, partners, analysts, journalists, the Department of Justice and even US Senators. What do open source software users think?

We asked the members of the “CAOS user community”* to tell what they thought of the proposed deal, as well as share some details on current database usage. The results have been published in the form of a 451 Group report (subscribers only) but here’s some of the headline figures:

• The use of MySQL is expected to decline from 82.1% of the 347 respondents today as 78.7% expect to be using it in 2011, declining to 72.3% 2014.

• The proposed

A number of people have recently raised the issue of the threat that cloud computing poses to the monetization of open source by specialist vendors, including Savio Rodrigues, Matt Asay, and Mike Hogan.

I believe that cloud computing provides an opportunity for open source specialists, but agree that cloud services based on open source code could potentially eat into the business opportunities for open source specialists since the cloud providers have no requirements

Savio Rodrigues has published a post arguing that cloud platforms such as Amazon Web Services and Microsoft’s Azure pose a threat to the monetization of open source by specialist vendors.

Savio makes a good case based on the recent launch of AWS’s Relational Database Service, based on MySQL, and Microsoft’s support for MySQL and Tomcat on Azure:

“When Amazon decided to offer MySQL via Amazon RDS, they did so without purchasing MySQL support from Sun. I’ve confirmed that Microsoft Azure is supporting MySQL on Azure without paying Sun for a MySQL Enterprise subscription.”

Clearly there is a threat to open source vendors from cloud-based services. Meanwhile I have previous
