4 Options for implementing the CEN metadata standards for cinematographic
works
4.1 General
Neither EN 15744 nor EN 15907 mandate a particular representation for conformant metadata. Interoperability
is assumed if metadata is communicated in a format that (1) preserves the meaning as defined in the
standards, and (2) can be produced and/or consumed by all parties taking part in an exchange of metadata.
Both standards specify element names and associated definitions, while EN 15907 additionally specifies
relationships between elements.
4.2 Data exchange options for EN 15744
4.2.1 General
EN 15744 specifies fifteen metadata elements similar in intent to many „core“ specifications such as the
Dublin Core Metadata Element Set (DCMES, ISO 15836:2003, revised 2009). For data exchange purposes,
EN 15744-conformant metadata can be prepared in one of the following ways.
4.2.2 EN 15744 mapped to DCMES
In cases where a party in a metadata exchange is unable to provide or consume EN 15744-conformant
metadata, or such metadata is to be merged with DCMES-based metadata, the element contents may be
transformed to a DCMES-conformant representation using the Dublin Core mapping statements contained in
EN 15744.
A representation transformed according to the DCMES may be encoded in any syntax endorsed by the Dublin
Core Metadata Initiative.
4.2.3 EN 15744 native
Metadata using the EN 15744 element specifications may be encoded in any syntax endorsed by the Dublin
Core Metadata Initiative. Where appropriate, this metadata may be combined with elements from other
standards and specifications, provided that any element not defined in EN 15744 is labelled with a namespace
reference indicating its origin.
4.3 EN 15907 Data exchange using XML
4.3.1 General
The following clauses specify requirements for an XML-based exchange of metadata instances conformant
with EN 15907. Further definitions based on different encoding schemes may be made available in the future.
4.3.2 Wrapper element
A wrapper element is required whenever more than a single instance of a Cinematographic Work element is
to be exchanged as a contiguous data stream. Depending on the exchange scenario, such an element may or
may not be defined by the exchange specification. Where this is not the case, sequences of Cinematographic
Work elements shall be enclosed in an ExchangeSet element.
4.3.3 Description units
Cinematographic Work
Since EN 15907 defines this unit of description as the reference point for any Variant and/or Manifestation, it
shall be used as the top-level element in an XML-based representation of a conformant metadata. This
requirement entails that a work-level identity shall be supplied even in cases where no work-level information

---------------------- Page: 7 ----------------------
SIST-TS CEN/TS 16371:2012
CEN/TS 16371:2012 (E)
about a Manifestation is available. It is the task of the metadata supplier to provide elementary work-level
identification, independent of whether this information is transitory, preliminary, or persistent.
Variant
Defined as optional in EN 15907, this unit of description may or may not be included depending on one of the
following conventions:
a) All work-level descriptions have a default instance of Variant. In this case, any instance of Manifestation,
even if not more than one is known, shall occur as a child element of a Variant.
b) A Variant is used to distinguish two or more sets of (one or more) Manifestations, and omitted if all
Manifestations are considered to belong to a single set. In the latter case, e
