SF' Subject: Re: [Opensdrm-general] OpenSDRM FAQ =20 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 ----- Original Message -----=20 From: Carlos <mailto:car...@gm...> Serrao=20 To: 'Panos' <mailto:pa...@ie...> ; 'Carlos <mailto:car...@is...> Serrao' ; 'OpenSDRM.
