[equinox-dev] Re: equinox-dev Digest, Vol 26, Issue 26 

Cameron,
Another plus for Equinox is that it's considered to be the reference (R4) implementation of the OSGi specification. Looking back through this mail-list or the newsgroup will give you a good idea of the large magnitude of people banging on it. Since Richard mentioned Felix, I feel less guilty about a small plug for Concierge. It's a R3 implementation that is considerably smaller and simpler, and now includes some PDE-like tooling to boot: http:// concierge.sourceforge.net/. 

Best of luck

Hello,
I'm building a case for using Equinox as opposed to in-house development of a plugin framework. Can someone given a reasonable estimate as to how many person hours have gone into the development of Equinox? Also, are there any estimates as to the number of Equinox installations that there are out there (i.e. deployment footprint)? This information would help to support my 
arguments for using Equinox.

Thanks much,

Also take into consideration the amount of time put into developing
the OSGi spec itself, and not just a particular implementation.  The
OSGi spec has been in continuous development since 1998.  Take a look
at Peter Kriens' review of JSR-277 (Java Module System), which is
bypassing the OSGi spec and attempting to solve the same fundamental
problem from scratch:

According to ohloh.net, 15 person years have gone into Equinox. This is a 
drastic underestimate, since Equinox is comprised of code from the
original Eclipse platform project (2000 person years and counting), and various other code contributions. The ohloh figure only captures the core 
Equinox OSGi implementation, and not the various other equinox bundles
that provide services on top:

http://www.ohloh.net/projects/3505
http://www.ohloh.net/projects/3855

As for install base, I'd venture a guess in the range of a hundred
million. The Eclipse platform built on Equinox has millions of downloads a 
year, and then there are the hundreds of commercial and open source
products built on it.  This is a vast install space, including desktop
apps, server-side apps, embedded apps, etc. You'll also find an equinox implementation or two in most linux distros. This is a pure guess - don't 
quote me on it.

In short, you'd be a fool to start from scratch. :-)
People generally think they can make a simpler implementation for their own usage, which is generally true. But over time your use cases expand and you end up creating something just as complex to handle all of your use cases. If your issues are dynamic extensibility, then your best bet 
at this point is the OSGi framework, since it has thought about nearly
all of the issues (although not solved all of them yet).
In addition, you can then choose from multiple implementations... (ahem, 
Apache Felix)  ;-)
