Definition

Technical specification relating to the digital encoding of text, image, audio, video, and other types of data in a tangible resource. This information could also be recorded in field 300 subfield ‡b.

File type and file size are core elements under RDA for cartographic materials only.  Use field 347 for tangible resources only. Under Provider-Neutral practice, online resources should exclude field 347 as elements may differ from one iteration to another. See Provider-Neutral E-Resource MARC Record Guide: P-N/RDA Version (http://www.loc.gov/aba/pcc/scs/documents/PN-RDA-Combined.docx) for additional guidance.

Subfields

 
‡a File type   A general type of data content encoded in a computer file.
347     audio file ‡b CD audio ‡2 rda
347     image file ‡b JPEG ‡2 rda
‡b Encoding format   A schema, standard, etc., used to encode the digital content of a resource.
347     text file ‡b PDF ‡2 rda
347     video file ‡b Blu-ray ‡2 rda
‡c File size  The number of bytes in a digital file.
347     data file ‡b XML ‡c 182 KB ‡2 rda
‡d Resolution   The clarity or fineness of detail in a digital image, expressed by the measurement of the image in pixels, etc.
347     image file ‡b JPEG ‡d 3.1 megapixels ‡2 rda
‡e Regional encoding  A code identifying the region of the world for which a digital file has been encoded which may prevent the file from being played on a player from a different region.
347     video file ‡b DVD video ‡e region 4 ‡2 rda
‡f Encoded bitrate   The speed at which streaming audio or video is designed to play.
347     audio file ‡b MP3 ‡f 32 kbps ‡2 rda
‡0  Authority record control number or standard number  Subfield ‡0 (zero) contains the system control number of the related authority record or a standard identifier such as an International Standard Name Identifier (ISNI). The control number or identifier is preceded by the appropriate MARC Organization code (for a related authority record) or the Standard Identifier source code (for a standard identifier scheme), enclosed in parentheses. See MARC Code List for Organizations (http://www.loc.gov/marc/organizations/) for a listing of organization codes and Standard Identifier Source Codes (http://www.loc.gov/standards/sourcelist/standard-identifier.html) for code systems for standard identifiers. Subfield ‡0 is repeatable for different control numbers or identifiers.
Local authority identifiers may be entered in subfield ‡0 locally, but should not be added to master records in WorldCat.
‡2 Source   Identification of the source of terms when they are from a controlled list. Prefer use of RDA terms.
347     audio file ‡b CD audio ‡2 lcsh
347     video file ‡b DVD video ‡e Region 1 ‡2 rda
‡3 Materials specified 

Part of the described materials to which the field applies.

347     ‡3 Compressed thumbnail ‡a image file ‡b JPG ‡d 3.1 megapixels ‡2 rda
347     ‡3 Uncompressed thumbnail ‡a image file ‡b TIFF ‡d 8 megapixels ‡2 rda
