Carlos and all

=20

I would prefer a simpler approach than PachyDRM's to FAQs

[Carlos Serrao] ok, fine by me.

=20

1)What is OpenSDRM ?

=20

Can we spell out the functionalities offered / to be offered ?

[Carlos Serrao] The functionalities for the current version are the ones =
you
already know:

-      Content registration;

-      Content preparation and protection;

-      User and component registration and authentication;

-      Payment;

-      License issuance and management.

=20

User Authorization

Content Registration

Billing

Content authoring/packaging ?

......

=20

=20

2) Melodeo-PatchyDRM is not free for commercial use although cheaper =
than
OMA and needs registration even to read  the spec=20

(any version around ?) What about OpenSDRM ?

[Carlos Serrao] The OpenSDRM license is  LGPL =96 this means it is =
open-source
and that it can be used in commercial and non-commercial environments. =
From
our vision document you have:

*	We have choose LGPL by the following reasons (I adapted this from
the JBoss project):

*	Freedom of Use: Use OpenSDRM LGPL software as a component of your
business applications in any way you wish, including linking to OpenSDRM
from your own or other proprietary software.
*	No Royalties or License Fees: customers, partners, and the end-user
community can make or download as many copies of OpenSDRM LGPL software,
without payment of royalties or license fees.
*	Ability to Distribute: customers, partners, and end-users may
distribute copies of OpenSDRM LGPL software.
*	Modify OpenSDRM for internal use: Anyone may make changes to
OpenSDRM LGPL software for use within your own company. The LGPL license
does not require you to share those internal changes with the rest of =
the
community.
*	Distribute modifications externally: Users may distribute changed
versions of OpenSDRM to others, but if you distribute such changed =
versions
you are required to share those changes with the rest of the community =
by
publishing that changed source code under the LGPL. This is known as
reciprocity obligation.
*	Inclusion of OpenSDRM products in commercially licensed offerings:
Unlike the GPL, the business-friendly LGPL license allows for OpenSDRM =
to be
embedded in or bundled with commercially licensed OEM and ISV products.

=20

The rest of FAQs may be easier but I need feedback on the =
functionalities
covered / to be covered=20

Would these functionalities be available as exposed WSDL services so =
other
developers can use them in their systems ?

[Carlos Serrao] Yes, that is and has always been the philosophy of =
OpenSDRM.

=20

How these functionalities can be orchestrated/choreographed in full =
fledged
services ?

[Carlos Serrao] Orchestration and choreography is something that we have
never treated as seriously has we have should =96 but i think it should =
be a
goal o OpenSDRM. This is something that might be achieved using BPEL4WS
(http://www-128.ibm.com/developerworks/library/specification/ws-bpel/) =
and
it needs to be developed within this OpenSDRM project.

=20

As you see we have a challenging project =96 even more because the DRM
momentum is building up:

-      DMP =96 working on the reference software (it will not be =
open-source
though, at least not commercially available);

-      PachyDRM =96 releasing to open-source, but not available =
commercially;

-      Coral Consortium =96 releasing their specifications to =
interoperability
of existing DRM platforms.

=20

Could you bring some more people to the project?

=20

Regards

Panos

Panos and all,

You seem to be a perfectly good candidate to do the Job. Are you a
volunteer?

=20

The questions you pop are meaningful, for sure and they are relevant. =
The
FAQ section of the OpenSDRM site already contains some information. You =
may
take a look at:

http://opensdrm.adetti.pt/index.php?option=3Dcom_content
<http://opensdrm.adetti.pt/index.php?option=3Dcom_content&task=3Dcategory=
&sectio
nid=3D3&id=3D7&Itemid=3D25> =
&task=3Dcategory&sectionid=3D3&id=3D7&Itemid=3D25

=20

You may take a look also to this FAQ =96 this is something I think we =
should
have: http://www.pachydrm.org/faq.html .

=20

You need to register at the site and I can provide you with editor and
publisher rights.

=20

Your help is mostly welcome.

=20

Best regards,
