"Open" is one of those words that is used a lot. It came into being as a reaction to the closed software offered by many software vendors. Since then Open and Free have become intermingled although it is not by lack of variants of open source licensing schemes. So why did we create another "Open Licensing" scheme?
Note: current explanation applies to Altreonic's software products. A similar Open Technology License is in the makring for the KURT e-vehicle technology.
It all goes back to some 10 years ago when we conducted a market research for one of our customers in the space sector. They wanted to find an alternative for a distributed RTOS. There aren't that many RTOS around that can handle multi-processing systems in a transparent way. The shocking discovery however was that the bulk of all RTOS, commercial or open source could not be certified, even when already available for years and that is true for a lot of software products. There are exceptions, but to start with, design documents are a rarity. Decent comments in the source code even less, not to speak of obfuscation techniques. The software might have been tested, but then there is a license that says "right to use at your own risk". And what about a user manual? What about (formal) proofs that the software meets the specifications? Not a wonder that the software industry, except for a few giants, is often a service industry. Thus we asked ourselves: Is there a better alternative?
The first observation to make is that proving and certifying software is difficult, not to say impossible, after it was developed. Testing will only prove the absence of errors for which the specific test was designed to detect. The tested code can still fail if the usage pattern is different from the one used by the test and secondly silicon issues have a tendency to pop up very seldomly. If we look at the requirements of the safety standards, then one sees that the development process is as important as the code itself. It comes down to minimising the risk that the software doesn't meet the specifications in all possible circumstances. Even formal proofing of source code has it limits. If one line of code is changed, how can one be certain that all specifications and model properties are still met?
So we came up with the logical step beyond "open source". We call it the "Open Technology License". First of all, it is a software license, copyright applies. It has all the rights to use it as it comes. It comes with source code, the formal models, the design documents, the build system, the user manual, the unit tests, examples, simulators, supporting tools like code generators, visual editors and debugging tools. It's not just software, it is technology. Licensees can reuse, modify, rebrand and create themselves binary licenses. A small royalty applies because support is proportional to the number of users. In the case of VirtuosoNext, it is more than just a kernel. It is a real-time software development suite for programming concurrent applications, ranging from very small microcontrollers to large distributed systems with 10000's of processing nodes. And it is designed for making application development certifiable.
You might also wonder why we propose this approach?
Altreonic is first of all a developer of technology with a focus on the high reliability / safety engineering market. Hence, the focus in on Research & Development. We have proposed Open Technology type Licenses from the very beginning based on the previous 25 years of experience that standard distribution/reselling doesn’t work very well for high-end software. The overhead and cost of selling is too high. At the same time, the distributor’s margin is a limiting factor. Some companies address this issue by using the software to sell expensive engineering services. But this means that the software is sometimes deliberately kept simple, not well documented, etc. But if you focus like Altreonic on high reliability (“trust”), this is not a very good option as it conflicts with the requirements for safety engineering. It can also turn out to be a costly and risky option for the customer.
This is where the Open Technology License comes in. What licensees acquire is the technology (fully documented) allowing higher margins, more added value but also more flexibility. Licensees have full access and are able to support the customer much better. Altreonic will support the licensees, but is often not involved with licensee's customers. Altreonic only asks for a small fee because the licensee will handle most of the support and because the engineers will be well trained. The annual support and maintenance as well as the small fee will provide the licensee with new versions with more features and better support tools.
Of course, there is a larger investment up front but this is a small fraction of what it would cost to develop the equivalent technology from scratch (and that would take a few years as well). Once the licensee integrates the technology with the other products and engineering services he offers, he will become more productive and will enjoying better margins. Hence, the initial investment is quickly recovered.
We plan to offer the same Open Technology License model for the technology we are still working on. There is the StarFish family of controllers but there is also an environment in development support engineering teams to develop their projects in the safety engineering domain with semi-automatic certification (think about D0-178B, IEC 26262, etc). We are already working on Virtual Machines, dynamic resource management, fault tolerance and formal modeling support. When these technologies are ready, we will offer them as well.
What our customers / technology partners acquire is an integrated, unified approach, leading to more reliability and higher productivity. The approach is valid for many vertical markets and this is the second important reason to adopt this open licensing model. Altreonic itself can never exploit the potential in all these markets, fast enough. But our partners, each specialized in its vertical market can. Some people ask why we make it so easy to access our technology that took years to develop. The reason is to allow us to focus and to deliver leading edge new technology. Hence, it is a win-win proposal.
We are currently selecting dedicated partners for the regional markets. Besides the Open Technology License we offer binary with source code licenses as well to the occasional user.
