14、oreword This document (EN 15907:2010) has been prepared by Technical Committee CEN/TC 372 “Cinematographic works”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the la

15、test by January 2011, and conflicting national standards shall be withdrawn at the latest by January 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all

16、 such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. In recent years, there has been a proliferation of new metadata standards intended to provide greater control, consistency and accuracy of the data in

17、 the ever-expanding environment of the World Wide Web, through, for example, links to shared named authority files. This is one of the main issues CEN/TC 372 “Cinematographic Works” had to address. It is also the case that the data that exists in many cultural organisations across Europe has been co

18、mpiled over many years and in some cases predates the advent of computer databases. To help reconcile some of the data inconsistencies that will inevitably exist in such a volume of data from so many disparate sources, this standard, together with EN 15744, seeks to provide a bridge between the data

19、 that exists and the emerging technologies chosen to represent this data. While the principle of EN 15744 is to enable the clearest possible enunciation of data that is available to assist with the task of resource identification, the aim of EN 15907 is to provide a framework for improved interopera

20、bility of that data by providing a common definition for that data. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark,

21、Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 15907:2010EN 15907:2010 (E) 5 Introduction Cinematographic w

22、orks are an essential component of European cultural heritage. Film history and culture is recognized as an integral part of everything from leisure to education, from art and fiction to documentary and is known to have a significant impact on culture and education worldwide. This has been emphasize

23、d by the European Parliament and Council Recommendation of 16 November 2005 on film heritage and the competitiveness of related industrial activities. Film archives, film museums, cinematheques, libraries and other cultural organisations have the responsibility to both preserve and make film heritag

24、e accessible. This responsibility includes acquisition of culturally important works; preservation through good storage and duplication to modern stable formats; curatorial research and interpretation; and programming and exhibition. Key to all of these activities is the responsibility of creating a

25、nd maintaining databases containing information about the films. Without such documentation preservation and access activities are not possible. At present, there is great variation in how filmographic databases are organized and implemented. Experts of all European countries have recognized that th

26、is variance stands in the way of interoperability and commonality of data. On 14 March 2005, the European Commission charged CEN with a mandate to create metadata standards for cinematographic works. In response to this mandate two standards, EN 15907:2010 and EN 15744:2009, have been developed to d

27、efine the metadata essential for facilitating data exchange between databases and consistent identification of films. The primary users of this European Standard will be film archives, film museums, cinematheques and any other cultural organisations with databases about audiovisual media. They will

28、also be the primary beneficiaries of the implementation of this European Standard throughout Europe as it will facilitate their access to filmographic metadata on works held by other organisations. Researchers, universities, students and the general public will also benefit in that it will be easier

29、 to integrate the information contained in the databases into larger information systems if it is organised according to these European Standards. The standards will also benefit film producers which, like the primary users, will be able to organize their metadata as defined by the standard. In cons

30、equence, these European Standards are expected to raise the visibility of Europes rich and diverse film heritage on the internet, and to improve access to it by citizens and professional users of cultural material in line with the objectives set out in the Commission Recommendation on the digitisati

31、on and online accessibility of cultural material and digital preservation of 24 August 2006. As requested by the European Commissions mandate, this standard provides a comprehensive set of metadata for the description of cinematographic works, as well as a comprehensive and consistent terminology, w

32、hereas EN 15744 defines and enables the selection of those data elements that are considered of prime importance for distinguishing and identifying individual cinematographic works. BS EN 15907:2010EN 15907:2010 (E) 6 1 Scope This European Standard specifies a set of metadata for the description of

33、cinematographic works, as well as a terminology for use by parties wishing to exchange such descriptive metadata. It also defines some basic entities and relationships useful for defining data models as well as for structuring hierarchically ordered and serialised representations of metadata about c

34、inematographic works including their variants, manifestations, and items. Specific vocabularies for values of elements and attributes are mandated only in selected cases, and only if these vocabularies are actively maintained by a standardisation body. 2 Normative references The following referenced

35、 documents are indispensable for the application of this document. For dated references, only the edition cited applies.

BS EN 15907:2010EN 15907:2010 (E) 7 3.6 relationship association between the same or different entities NOTE Relationships may have attributes. 4 Primary Entities 4.1 Cinematographic Work 4.1.1 General This entity forms the node that relates all vari

40、ants and manifestations of a moving image work to a common creation. The concept of cinematographic work comprises both the intellectual or artistic content and the process of realisation in a cinematographic medium. Since this process determines the characteristics which are expected to persist in

41、any variant of a cinematographic work, this entity is defined here as the topmost level of description. Characteristics that should remain constant throughout all variants of a cinematographic work include circumstances of the creation process such as date(s) and place(s) of production, most contrib

42、utions by agents such as directors, screenwriters, production staff and cast members, as well as any statements about the contents. Statements about the extent of a cinematographic work are not defined at this level of description. If a statement about an “original format“ is required, then this may

43、 be expressed through an associated instance of manifestation labelled with a suitable type name such as “original“. A cinematographic realisation of a pre-existing non-film work is considered as a cinematographic work. This includes pure performance works such as concerts, original theatre performa

44、nces, sports events, etc. Moving images created by use of automatic devices such as surveillance cameras, scientific or medical instruments, etc. can be considered as cinematographic works if they are part of an archive collection or if they have been edited, published or distributed by a known Agen

45、t. Instances of the Cinematographic Work entity may have one-to-many relationships with instances of Variant and Manifestation and many-to-many relationships with instances of Agent, Event and Content. 4.1.2 Attributes descriptionLevel A one-character symbol indicating the role of the cinematographi
