Why FIWARE IoT exists when we already have solutions such as IoTSYS, Domotic OSGi Gateway, openHAB and others?

First of all I have to admit that I find the FIWARE project very interesting and it really targets the current technological needs the world is facing at the moment.

However, I believe that some FIWARE components could use already existing solutions instead of reinventing what already exists for some time. If you look closely you will see that, aside from the names given to equivalent concepts, FIWARE Architecture is very similar to the ones I mention in the title. Not that FIWARE is ripping off ideas, it is just that these things already exist and the final solutions are very similar.

Moreover, the main problem is that there are as many solutions to solve the IoT hardware heterogeneity problem as devices they try to integrate. In the end, creating more integration frameworks and standards will solve no problem at all, it will aggravate it even further by spreading manufacturers and developers attention to several means of integration, mitigating the purpose of integration frameworks and standards!

First we had BACnet/WS, OPC DA, oBIX etc. Then we had UPnP, CoAP and 6LoWPAN. After there were DOG, openHAB and IoTSYS. Now we have FIWARE and AllJoyn! Please we have to find another way to solve this severe issue.

OR is there a reason that I am unaware justifying the creation of another integration framework?

Hi,

thanks for asking the question and giving us the opportunity to discuss some of the advancements provided by FIWARE.

Let me go to the issues your raised and your arguments. Then I try to point out the advantages of FIWARE.

(a) Hardware Heterogeneity Problem
I agree that one on the issues to solve is hardware heterogeneity. There are other ranging from global identifier, discovery, fast control loops, Cloud mashups, large scale distribution, scaling to Billion of Objects - just to name a few.

(b) Existing Systems
You mention lot's of different systems ranging from BACnet/WS to 6LowPAN. I think you will agree that they are NOT doing all the same. And that they in many cases created for a specific use and a specific deployment. The amount of different systems shows basically how old M2M is actually.

Example 6LowPAN: target is to have a IP layer on top of a low-bitrate wireless network. It is optimized for compressing IPv6 in a few bytes. While good for its special use case, I doubt that it makes sense to use it with a wired infrastrucutre or over a 3G/4G/5G network. I don't think it is suitable in an Cloud environment, for integrating IoT into the Internet-of-Services, or other aspects.

(c) Similar problems in a total different areas
Let me point you to another area in which we have a similar observation - many (legacy) systems, no agreement on a single one. I am talking about programming languages. But you can replace it with OS, databases, ... There are thousands programming languages out there. Some obscure, some useful, some outdated, some specialized. Some of the real important new ones came with real important advancements in the understanding of programming, in having ideas how to avoid common errors, or on how to do support libraries right. - C was born to have something better then Assembler. - Pascal was invented to show the quality of structured programming. - Java was doing object-oriented programming in a (still) procedural environment right (or maybe just better ?) and also improved a lot stability and to some extend portability

So at the end, they are not all born equal. They are created for specific purposes with a specific target environment in mind.

So why are some more successful then others? Maybe because they do a few things better then their competition, maybe they simply spotted a change in the typical usage environment faster then others and provide respective abstraction. They win, because the provide additional value to the programer, e.g. by being more productive or by easier solving specific aspects. Java was really a step forward for the Internet. Simple concepts as namespace bound to DNS domains helped to isolated the development effort from many people so that the resulting code could be much easier integrated without big renaming.

By now I hopefully have established that concrete system are solving problems they are designed for, and that in a changing world new system might be able to deal ... (more)

thanks for a so detailed response. I think it might worth a blog article on fiware.org

Thanks for the idea. It is a good one.
