[Opensim-dev] The Future of Open Simulator - Accessibility and Business perspective

Hi OpenSim dev list


I think Douglas question regarding a product roadmap is very relevant, so I
will just comment on it from my point of view, were I want to use
OpenSimulator as a learning platform for K12 students. 

I am still new to OpenSimulator, therefore I will try to look at the project
from a accessibility and business perspective and only comment briefly on
the architecture. 


My background: 

I have worked 20 years as freelance solution architect, senior developer,
product manager for Software Innovation DK and in many R&D units and
recently as enterprise search specialist. I have only developed a few
teacher and student tools with a shared region module for OpenSimulator
http://www.oligo.academy/tools/, so my ideas for architecture are not based
on or limited by practical experience with this platform - think of them as
ideas for a general discussion towards a project road map.   

I think the key driver for everything else, is the accessibility and
business opportunities perspective and therefore also the viewer experience.
There has been some good ideas with the OnLook viewer and PixieViewer, but I
think the scalability and accessibility issues need to be solved in the
backend services.


My short 2 points wish list for OpenSimulator roadmap is:

Priority 1) Make support for new protocols to build fast browser based
viewers and have better scalability 

To make OpenSimulator accessible to more people and use cases on any device,
by implementing backend services for browser based viewers. Perhaps using
mean.io stack with MongoDB and also threejs.org (see scene loader example),
to create a cache in MongoDB that makes is possible to build a fast browser
based viewer, by structuring data as the viewer needs it. The browser based
viewer should only have simple build tools and persist to the OpenSim
database. Is the core OpenSimulator code the right place to solve
accessibility and scalability issues or can my suggestion coexist with the
current implementation?

I think it is important to keep compability with existing software stack,
while building new services for new requirements. Linden Labs decision to
move on will make many content creators look towards OpenSim grids and
services like Kitely market.  

Priority 2) Clear and up-to-date documentation

- Make better installation and system management documentation for running
hybergrids, setting up proxy servers to avoid firewall issues and any other
problems users and administrators run into. 

- Update plugin and shared region module development examples and
documentation to make it easy for new developers to add features and follow
coding standards. Perhaps make it easy to search for recently updated
information on the opensimulator website.


Why is a project road map so important?

I think it's important to identify long term goals in a project road map:
like what do we need to do to make the best scalable hybergrid platform,
most secure platform for kids, to improve accessibility of this software or
to support content creators and content sharing. Having a roadmap makes sure
the objectives are common knowledge and will help the constant progress.
Having a legal entity like Overte used to be, also makes it possible to get
public funding, which can also help the progress of the project. 


Why should accessibility be prioritized?

The goal of a fast browser based viewer protocol or a secure learning
environment, are requirements for schools that have a "Bring your own
device" strategy and need to adhere to children's protection act. It would
also open up the platform for many more users and business cases. When no
viewer installation is required not only school kids would benefit, but also
business cases like online interactive museums, galleries, auctions etc. 

I think the support for WebGL is quite good (http://caniuse.com/#feat=webgl
and mature frameworks like ThreeJS have good examples
http://threejs.org/examples/#webgl_loader_scene. Therefore I think the
conditions to succeed are in place, if we can build backend services to
support fast browser based viewers, without the constrains of the existing
protocols.  



PS: Thanks to all people, who have contributed to this great project over
the years, it has a lot of potential - let's make it more accessible to more
people ;-) 


Have a nice day 

Regards Nikolaj

v/r -doug
This can be considered my ?wish list? as I don?t really have a say in what
happens, but I?m willing to put in a fair share of work in seeing that it
can be done if others agree these are desirable targets:

1) Restating what Doug has mentioned, Clear and up-to-date API
documentation. This hinders contributors, myself included, from working on
things and leads to a lot of frustration and disappointed from
well-intentioned folks.

2) A coding standard that defines and formalizes the style of code used
throughout the codebase and is adhered to and enforced and should be pointed
to often and regularly for contributions. Good code is easy to read and
manageable. A formal coding standard is a good step in that direction.

3) OpenSim is a thread monster. There doesn?t seem to be any sort of
approach to how threading is handled. This I think would fall under Doug?s
criteria for #1.

4) I think it?s time to hop off the fence and decide whether to maintain the
Second Life protocol compatibility, (Which, let?s be honest, is pretty
lacking. There?s a lot missing post-2010.) or to break new ground. Linden
Lab has apparently made their decision regarding that. There are viewer
developers out there willing to work with OpenSimulator is doing this. I am
one of them. I just can?t be in IRC all the time, but I want to do this with
you guys and I know there are others out there willing to put in the work to
build clients to connect to new and better worlds with sensible protocols.

Please don?t take any of this as criticism as it is not meant as such. I
appreciate all the work that everyone on this project and who is affiliated
with it does.

Doug,

I like all of those ideas.  They would make my life significantly easier and
my research far more plausible!

I won't comment much over future direction.  However, Overte was never a
governing entity, it was set up only to manage CLAs and maybe some other
things in the future (which never got realized).  Power over development
direction has always been with the developers.

CLAs for open-source projects tend to come from corporations running those
projects that are very worried about getting sued.  The vast majority have
no such structures.  It is very debatable whether anything other than the
open-source license is needed.


And there are many different project structures out there.  Linux, for
example, is controlled by a single individual who, along with a group of
authorized lieutenants, controls everything that goes into the codebase.
That is an evolution since Linus used to be the sole committer (and got
overwhelmed by it).

The direction of evolution is not inevitably to some managing organization. 
Or at the very least, the developers much always be in charge of what
happens to the codebase.

	Projects evolve.

	I couldn't begin to estimate the amount of work that has gone into
this
	valuable project.  The potential for technical and economic success
is
	profound and I see a bright future for the Open Simulator.  That
said, I fear
	we are at a crossroads at this time with this project.

	It is unclear at this time what the maintainers of the Open
Simulator code
	have planned for the project.  Is there a roadmap or some sort of
	goals/objectives you are working against?  What development targets
would you
	like to see met in 12, 16, and 24 months from now?

	The MOSES project has needs & requirements that we are stepping up
and
	supporting with internal development, but we aren't the drivers for
the Open
	Simulator project.  We've done our own internal gap analysis and
determined
	where in the OS code there should be investment in stability,
monitoring, and
	scalability improvements.  In short, we are returning our code to
you to
	adhere and abide by applicable derivative source code licensing
terms.

	I believe the removal of the Overte as a formal governing entity is
a mistake
	if you plan to encourage participation from business and government.
The CLA
	was viewed by my organization as a formalized relationship
acknowledging the
	legal responsibility of open source code stewardship and use.

	If this were simply a hobby, then Overte and the CLA would not be
needed.
	However, the Open Simulator is being used by businesses charging
money for
	service, by researchers studying human behavior and technical
behavior, by
	educators, and more.  Like it or not, you have created a product
that needs
	management and attention at a higher level than the ad-hoc method
that is
	currently your standard operating procedures.

	Project management must evolve.

	As projects are started at the grass roots and then emerge as valued
	commodities, the need for different styles of management is
required.  A
	project with two active developers is different than a project with
20 or 
200.
	If the management does not evolve, then the project will be limited
and 
growth
	is not possible.  I encourage you to think about a new structure
that can
	handle influx of large amounts of donated code in a short time.  The
kinds of
	investments needed to make this a world class simulator requires you
to step
	up and begin project planning.

	This is a community effort.

	If the community values this work and would like to see it grow or
even
	receive maintenance, then the community must voice.  This code does
not 
belong
	in the hands of a gov't agency or corporate entity.  This code
belongs in the
	hands of a strong non-profit that can handle grant and contract
funds to pay 
a
	staff of maintainers, code reviewers, testers, and functional area
code
	managers.  This could be an Overte spin-off, or even an academic
institution
	of some kind.

	I've given you a glimpse into what the next 9 months of development
for the
	MOSES related Open Simulator issues.  We came in this spring at a
time when
	development seemed to be winding down and things were quiet after
the 0.8.x
	releases.  What will you do when we reach the logical conclusion of
our work?
	What is next for Open Simulator?

	I look forward to your feedback and constructive discourse.

I'd love to see a "Convention over Configuration" approach. What I mean is
that OpenSim come configured for best practices.
