ern:ResourceGroupContentItem

A message term for ern:NewReleaseMessage.

A Composite containing details of a Resource which is a ContentItem of a ResourceGroup.

Component Structure
Components	Name	Description of Element Role	Cardinality	Data Type
	XmlSequence		1
	SequenceNumber	The number indicating the order of the ContentItem among all Resources within this ResourceGroup. This is analogous to the Track number on a SoundCarrier. Not all ResourceGroups necessarily have SequenceNumbers (it is most applicable to SoundRecordings and MusicalWorkVideos). The SequenceNumber is unique within its ResourceGroupLevelNumber.	0-1	Integer (xs:integer)
	SequenceSubNumber	The SequenceNumber within the SequenceNumber. Example: if a Track is subdivided into several numbered sections, these are numbered with a SequenceSubNumber. The SequenceSubNumber is unique within its SequenceNumber.	0-1	Integer (xs:integer)
	ResourceType	A Composite containing details of the Type of the ContentItem.	0-n	ddexC:ResourceType
	ReleaseResourceReference	A Composite containing a ReleaseResourceReference for the ContentItem (specific to this Message). The LocalAnchorReference in this Composite is a xs:string starting with the letter A.	1	ddexC:ReleaseResourceReference
	LinkedReleaseResourceReference	A Composite containing details of a ReleaseResourceReference (specific to this Message) for a Resource which is linked to this ContentItem. Example: an Image, Text or NonMusicalWorkVideo associated with a SoundRecording. This LocalAnchorReference is a xs:string starting with the letter A.	0-n	ddexC:LinkedReleaseResourceReference
	XmlChoice		0-1
	ResourceGroupContentItemReleaseReference	The Identifier (specific to the Message) of a Release which has the same content as the ern:ResourceGroupContentItem. This is a LocalReleaseAnchorReference starting with the letter R.	1	IDREF (xs:IDREF)
	ReleaseId	A Composite containing details of ReleaseIds of a Release which has the same content as the ern:ResourceGroupContentItem. If available, a GRid has to be used. If the Release contains only one SoundRecording, the ISRC of the SoundRecording may be used instead. If the Release is an abstraction of a complete PhysicalProduct (such as a CD Album), the ICPN of the PhysicalProduct may be used instead.	1	ddexC:ReleaseId
	Duration	The Duration of the ContentItem featured, if it is a SoundRecording or Video (using the ISO 8601:2004 PT[[hhH]mmM]ssS format, where lower case characters indicate variables, upper case characters are part of the xs:string, e.g. one hour, two minutes and three seconds would be PT1H2M3S). This Duration may be less than the normal Duration of the ContentItem, if only a part of it is included.	0-1	Duration (xs:duration)
	IsHiddenResource	The Flag indicating whether a Resource in a Release is hidden in some way from the Consumer (=True) or not (=False).	0-1	Boolean (xs:boolean)
	IsBonusResource	The Flag indicating whether a Resource in a Release is additional to those on the original Release of which this is a Version (=True) or not (=False).	0-1	Boolean (xs:boolean)
Is Member of Composites	Composite Name	Description of Element Role	Cardinality
	ern:ResourceGroup	A Composite containing details of a Resource contained in the ern:ResourceGroup.	0-n
