[dsdp-tm-dev] Re: Service Discovery beta

[javier.montalvoorus@xxxxxxxxxxx]

Hi Martin,

To propose the service discovery to
the PCM here are the answers to the questions from your previous mail:

Does your contribution depend on RSE or any other components
(except EMF)? What parts of EMF (SDO, XSD)?
No, the current version is only depending
on basic EMF.

I suppose the Sample View depends on the Zeroconf engine,
which depends on the EMF Model, right?
The sample view depends on both engine and model, as it
sets up a service discovery query using the engine and also displays the
contents of the model.

Did you prepare for any APIs or extension points where
users could plug in their own protocols or models?
Yes, the code provides a factory and interface to extend
the transport mechanism (only UDP/IP is implemented at the moment).
If  anybody requires other parts of the service discovery
plugin to be extendable, please let me know. 

And the IP/Legal questions: 

Did you write the code your own from scratch or did
you use any legacy code?
Yes, all code was written from scratch.

Did you reference / include / copy any 3rd party materials?
If yes, under which license did you receive such materials?
No.

Are you authorized by your company to make the contribution
under the EPL?
Yes.

Please, let me know if you require more
informantion about service discovery.

Hello Javier,

thanks for all your work on this!

I'm copying the dsdp-tm-dev list in order to keep the Community informed
and in the loop. The Community can ask additional questions or make suggestions.

In order to propose this to the PMC, I'll need to know about the dependencies:

• Does your contribution depend on RSE or any other components (except EMF)? What parts of EMF (SDO, XSD)?
• I suppose the Sample View depends on the Zeroconf engine, which depends on the EMF Model, right?
• Did you prepare for any APIs or extension points where users could plug in their own protocols or models?

I
suppose that some of this information will eventually need to go into some
sort of documentation. Remember that all of Eclipse is more about Frameworks
and Exemplary tools, than full-blown applications
Then I'll need to ask the IP/Legal questions:

• Did you write the code your own from scratch or did you use any legacy code?
• Did you reference / include / copy any 3rd party materials? If yes, under which license did you receive such materials?
• Are you authorized by your company to make the contribution under the EPL?

Regarding the code, you'll need to
put proper EPL Copyright Notices into all your source files, like these:
   http://www.eclipse.org/legal/copyrightandlicensenotice.php
and you'll need to add about.html to the root of your plugins, like these:
   http://www.eclipse.org/legal/epl/about.php
see http://www.eclipse.org/legal
for more information. These copyright notices have to be in the code _before_
we can submit it to EMO legal review.

Of course it's up to you to attach the code on bugzilla before doing all
this, to enable earlier community review.

But actual EMO Review - and thus the start of the submission process -
requires these. Some more guidelines regarding the code are here:
   http://www.eclipse.org/legal/committerguidelines.php
these guidelines are more for the committers reviewing your code, but it'll
be good for you to know these as well. The most important of these are
that your code must not contain profanity, and that cryptography, patents
and other "legal" things need to be documented.

Thanks again,
Martin

Hi Martin, 

I have at the moment a functional beta version for the service discovery.
It shows how services can be discovered and provides a view displaying
the available services and their specifications. 
I think it will be really useful to start testing the service discovery
engine and also it  will allow developers to start working on the
device implementation of zeroconf servers. 
The solution is based on EMF but the architecture is modularised enough
so it is be really easy to improve/substitute any of the components.

The original submission will contain the following plugins:

*  Zeroconf engine 
Containing the different transport implementations and the APIs to instantiate
them. At the moment only UDP has been implemented (mainly for testing),
but new transports can be easily added by implementing an interface and
making it  available through a factory. 
It also contains the zeroconf protocol implementation, encode and decode
of the zeroconf packets and population of the model as well as a public
API to perform the actions. 

*  EMF model 
EMF model created from the XML schema I posted in the bugzilla entry.

*  Sample View 
A view providing basic manipulation of the engine (discovery/refresh/delete)
and showing the discovered services and their attributes. 
This view is provided only as a proof of concept and it's not intended
to be the final implementation. Porting the model from one view to another
will be quite easy using the EMF facilities. 

My idea is to provide the beta version through an attachment to the autodetect
bugzilla entry, is it then covered by EPL ? 
Can you give some guidance about the submission process ?  In the
meantime I'll be discussing the submission with my team and the legal department.

Many thanks,
