Title Open Media Marketplace basics No. 1275rev.05/OMM

Open Media Marketplace basics

1 IntroductionPurpose of this document is to collect the basic elements of the Open Media Marketplace (OMM) project. The document is based on previous versions of the OMM documents and has benefitted from the advances made by the MPEG Ad hoc group on Advanced IPTV Terminal in Milan on 9-10 September.

2 Basic OMM requirementsAt a rather abstract level the OMM is an environment where Users perform actions (described by Verbs) on Entities using Services provided by Service Providers. The OMM is enabled by the OMM specification satisfying the following requirements.

1. OMM shall enable the provisioning of interoperable Services between OMM Users2. OMM shall support the following Basic Services listed in chapter 53. OMM shall enable a Service Provider to combine several Basic Services into one Aggregated

Service4. OMM shall enable different Providers to offer the same Basic Services and the same or partially

overlapping Aggregated Services5. OMM shall provide the means to realise a Service Provider either as a standing entity operating

on the OMM or as an application running on a local machine, potentially with different levels of user experience for the user

6. OMM shall facilitate the separation of technological, governance and legal concerns to enable OMMs underpinned by different forms of governance and legal systems

7. OMM shall support commercial exploitation of content such as:1. Advertising: based on context, user usage;2. Payment/donation for content;

8. OMM shall enable OMMs where access to Services requires the establishment of a business relationship between User and Service Provider

9. OMM shall enable OMMs that only require access to the Service Provider a User is subscribed to in order to access a given type of Service in the value chain (e.g. like in OpenID where I subscribed to one OpenID Service Provider and I am recognised by all other OpenID Service Providers)

10. OMM shall enable secure and confidential transmission of information11. OMM shall enable Services of different features and levels such as interactivity, local storage,

and time, space and device shifting

12. OMM shall enable Services that are independent of the delivery system such as broadcast, fixed network, mobile network and packaged media, as well as hardware platform such as PC, mobile phone and set top boxes, bearing in mind that

1. Some features of the standard may not be implementable on some delivery systems and/or hardware platforms

2. Some parameters may need to be set to specific values to suit the specifics of some delivery systems and hardware platforms for optimum performance

3 OMM EntitiesThe table below provides a list of definitions of the Entities on which Verbs can be applied.

Entity DefinitionContent A Digital Item and its component elementsDevice An IT (hardware/software or simply software) apparatus that enables a User to play a

role in OMMEvent The performance of a specified set of Functions including relevant descriptions (who,

on what, when, where)Group A set of Users or DevicesLicence A collection of authorisations, conditions and payment terms granted by a User to other

UsersObject A Content Item or a ServiceReputation A measure of the credibility of or the possibility (e.g. legal) for a User to be a party in a

TransactionSequence The identity and the temporal order of Content ItemsService A set of Functions executed by a User on behalf of other UsersTool Computer code to manage and protect ContentUser Any participant in OMM

4 OMM VerbsThe table below provides a list of definitions of the Verbs that can be applied to Entities.

Verb DefinitionAdapt To perform changes to a Content ItemAuthenticate To confirm the identity of an EntityDeliver To transfer Content between any two or more DevicesDescribe To add descriptive information to an EntityIdentify To assign an identifier to an EntityInteract with To trigger an action via Content presentedLocate To find the URI or physical location of Entities satisfying given conditionsManage To handle the life cycle of an EntityNegotiate To assist Users to seek agreement on a TransactionPackage To make a Content Item suitable for DeliveryPost To provide an organised structure of Content URIs

6 OMM Basic Service specificsNote: a User must call Initiate Service the first time in order for the services of an SP to be accessed and may call Terminate Service when a User intends to discontinue access to the SP’s services.
