All Implemented Interfaces:

MetadataSet

public final class CommonMetadataSet
extends java.lang.Object
implements MetadataSet

CommonMetadataSet specifies an encompassing list of attributes that are applicable across different platform, bearer and operator specifications. For completeness, this list had been validated against the ESG specifications from DVB-CBMS V.13 and OMA-BCAST V.1. The detail mappings from the JSR to the aforementioned specifications are described in the DVB-CBMSv13, OMA-BCASTv1, JSR272 ESG attributes mappings: Open Document Spreadsheet version, Microsoft Excel version.

All JSR-272 implementations MUST support CommonMetadataSet. i.e. ServiceGuide.getSupportedMetadataSets() will return at least CommonMetadataSet. Static getInstance() method can be used to access CommonMetadataSet directly without need to query the list of MetadataSets from the ServiceGuide.

Attributes prefixed with "PROGRAM_" refer to ProgramEvents, attributes prefixed with "SERVICE_COMPONENT_" refer to ServiceComponents, attributes prefixed with "PURCHASE_" refer to purchasing and the rest refer to Services. Table below shows which Attribute types can be used to query information from classes implementing ServiceGuideData. In the table, "Yes" means that the Attribute type can be used to query data from given type of ServiceGuideData interface whereas "No" means that it can't.

Attribute	ProgramEvent	PurchaseObject	Service	ServiceComponent
PROGRAM_*	Yes	Yes	Yes	Yes
PURCHASE_*	Yes	Yes	Yes	No
SERVICE_*	Yes	Yes	Yes	Yes
SERVICE_COMPONENT_*	Yes	No	Yes	Yes

Following incomplete piece of code gives an example.

 Services[] services = ServiceGuide.findServices(someQuery);
 String sid = s[0].getStringValue(CommonMetadataSet.SERVICE_ID);
 String[] names = s[0].getStringValues(CommonMetadataSet.PROGRAM_NAME);
 Date[] startTimes = s[0].getDateValues(CommonMetadataSet.PROGRAM_START_TIME);
 

Technically, the code above works fine and most of time the result probably is as expected. However, the order of the of the values returned from get value methods is unspecified. Therefore, the code below is safer, for instance, to create a list of program names and their starting times.

 Services[] services = ServiceGuide.findServices(someQuery);
 ProgramEvent programs = s[0].getPrograms();
 for (int i = 0; i < programs.length; i++) {
        String name = programs[i].getStringValue(CommonMetadataSet.PROGRAM_NAME);
        Date startTime = programs[i].getDateValue(CommonMetadataSet.PROGRAM_START_TIME;

        // do something with the information ...

 }
 

Detailed description about the use of Attributes in queries is in ServiceGuide documentation.

Unless otherwise noted, all attributes can return zero, one or more associated values. However, a valid CommonMetadataSet must not return zero values for all attributes. At least one value must be returned for some attribute. ServiceGuideData provides two different versions of methods to access either one (default) or multiple values. See ServiceGuideData.

URI Syntax and Semantics
The URI syntax for Service, Programs and various related data are not defined in this specification. They are broadcast/transport bearer dependent. Applications that target to be bearer independent should reference the ESG attributes and not rely on the specific URI syntax.

The ESG may specify URIs of various broadcast auxiliary data; e.g. SERVICE_REL_MATERIAL, SERVICE_AUX_LOGO, PROGRAM_CONTENT_AUX_SOUND etc. These URIs can be of different types, for example:

1. URI pointing to a local file:
   • The media is broadcast inlined and stored as a local file when received.
   • The media is transmitted in the ESG Carousel and stored as a local file.
2. URI pointing to remote interactive content. In this case, the scheme of the URI determines the type of connection (i.e. protocol). Example: "http://mtv.com/mobile/MTVLogo.jpg".
3. URI pointing to a broadcast stream/file (outside ESG carousel). These could be data received as A/V streams and broadcast files.

An InputConnection can be created from these URIs using the Generic Connection Framework (javax.microedition.io.Connector). See auxiliary data example.

Genres and Ratings
The different genres and ratings are not defined in this specification. They are broadcast specification dependent. For example, TV-Anytime's metadata specification defines an extensive list of genres (ContentCS) and ratings (IntendedAudienceCS) that are adopted by other broadcast specifications like DVB.

It is possible to use the API to query for all applicable values for genres and ratings by using ServiceGuide.getAllUniqueValues().
