Entity 3: A file that makes up the overall object. An internal identifier – a number assigned by NLNZ to a digital file. The directory path within a complex object that points to this file. The name of the file as it is held in the digital archive. The name (including extension) of the file as it existed in the source material. The size of the file in bytes. Date/time that this file was created. The Multipurpose Internet Mail Extensions Type for the file expressed as type/subtype. http://www.isi.edu/in-notes/iana/assignments/media-types/media-types Examples are: video/quicktime, image/jpeg The format of the file taken from the name of its type or the application used to create it. The version of the file format identified in 3.9.Examples are: V2.0, XPAlthough file format versions may be able to be verified against a list, the proliferation of new versions may make this impractical to enforce. An indicator to show whether this file is the entry point for accessing a complex object. A file is subcategorized into the following account The unit of measurement for X Sampling Frequency and Y Sampling Frequency. Equates to NISO field 8.1.2 The number of pixels per Sampling Frequency Unit in the image width (horizontal dimension). The number of pixels per Sampling Frequency Unit in the image length (vertical dimension). The width of the digital image, i.e. horizontal or X dimension, in pixels. he length of the digital image, i.e. vertical or Y dimension, in pixels. The number of bits per component for each pixel. Equates to NISO field 8.2.1Note that this field allows a different number of bits per component for each component corresponding to a pixel. For example, RGB colour data could use a different number of bits per component for each of the three colour panes. Most RGB files will have the same number of Bits Per Sample for each component. Even in this case, the writer must write all three values. 1 = 1 bit (bitonal) 4 = 4 bit grayscale 8 = 8 bit grayscale or palletised colour 8,8,8 = RGB 16,16,16 = TIFF, HDR (high dynamic range) 8,8,8,8 = CMYK See comments for attributes Designates the colour space of the decompressed image data. Equates to NISO field 6.1.4.1 0 = WhiteIsZeroFor bilevel and grayscale images: 0 is imaged as white. 2**BitsPerSample-1 is imaged as black. This is the normal value for Compression=2. 1 = BlackIsZeroFor bilevel and grayscale images: 0 is imaged as black. 2**BitsPerSample-1 is imaged as white. If this value is specified for Compression=2, the image should display and print reversed. 2 = RGBIn the RGB model, a colour is described as a combination of the three primary colours of light (red, green, and blue) in particular concentrations. For each of the three components, 0 represents minimum intensity, and 2**BitsPerSample-1 represents maximum intensity. Thus an RGB value of (0,0,0) represents black, and (255,255,255) represents white, assuming 8-bit components. For Planar Configuration = 1, the components are stored in the indicated order: first Red, then Green, then Blue. For Planar Configuration = 2, the Strip Offsets for the component planes are stored in the indicated order: first the Red component plane Strip Offsets, then the Green plane Strip Offsets, then the Blue plane Strip Offsets. 3 = Palette colourIn this model, a colour is described with a single component. The value of the component is used as an index into the red, green, and blue curves in the Colour Map field to retrieve an RGB triplet that defines the colour. When Photometric Interpretation = 3 is used, Colour Map must be present and Samples Per Pixel must be 1. 4 = Transparency MaskThis means that the image is used to define an irregularly shaped region of another image in the same TIFF file. Samples Per Pixel and Bits Per Sample must be 1. PackBits compression is recommended. The 1-bits define the interior of the region; the 0-bits define the exterior of the region. 5 = CMYK 6 = YCbCr 8 = CIELab The name of the International Color Consortium (ICC) profile used. The location of the file containing the colour map. Orientation of the image saved on disk e.g. normal, normal rotated 180-.Normal is defined as follows: when opened, the top (0th) row of pixels corresponds to the visual top of the image and the first (0th) column of pixels on left corresponds to the visual left-hand side of the image.Consult TIFF for additional values referring to mirrored images. (Note that TIFF/EP supports only five values, which are proposed above as the finite list of enumerated type values.)This field is to be used to record only the orientation of the image, not the orientation of the source to the device (e.g., camera) used to capture the image.Equates to NISO field 6.2.4 1 = normal* 3 = normal rotated 180deg 6 = normal rotated cw 90deg 8 = normal rotated ccw 90deg 9 = unknown The compression scheme used to store the image data. Values above are drawn from TIFF (p. 117) though institutions are encouraged to devise a local enumerated list to allow for the addition of new values as technology changes. This data element allows for the designation of sub-elements in order to record the level of compression applied (see 3.12.8.2 Compression Level).Equates to NISO field 6.1.3.1 1 = Uncompressed 2 = CCITT 1D 3 = CCITT Group 3 4 = CCITT Group 4 5 = LZW 6 = JPEG 32773 = PackBits (simple byte-oriented run-length scheme) Designates the level of compression used in 3.12.8.1 Compression Scheme. The rate of sampling, in samples per second, used to create the audio file. Also known as sample rate or sample frequency. The length of the audio recording in hours, minutes and seconds and three digits for representing decimal fractions of a second. Equates to EBU P_META Scheme Attribute A428Examples are 01:27:38:247 The word length used to encode the audio. Consequently an indication of dynamic range. It is the maximum number of significant bits for the value without compression. Equates to EBU P_META Scheme Attribute A175Examples are: 16, 20, 24 The name of the compression scheme, noise reduction scheme, or other non-linear processing applied to an audio signal. Note that audio compression, or bit rate reduction is a non-reversible, "lossy" process.Equates to EBU P_META Scheme Attribute A257Examples are: MPEG 3; Dolby A; IEC pre-emphasis The name of the delivery format of the file. The version level of the delivery format of the file. A classification of the sound format type identifying the number of channels and how they are related to each other. The width of the digital image, i.e. horizontal or X dimension, in pixels. The length of the digital image, i.e. vertical or Y dimension, in pixels. The length of the video recording in hours, minutes and seconds and three digits representing decimal fractions of a second. Equates to EBU P_META Scheme Attribute A428 Examples are 01:27:38:247 The number of frames present in the video recording. The rate at which the video should be shown to achieve the intended effect expressed in frames per second (fps). Equates to EBU P_META Scheme Attribute A44Example: 25 The name of the codec method applied to the video. The version level of the codec method applied to the video. The desired aspect ratio of the image on screen. An indicator showing whether the digital item is scanned in a progressive or interlaced mode. An indicator of the presence of sound in the video file. If the value is yes, then the video file will also be associated with an instance of the Audio metadata (3.13) in addition to the Video metadata (3.14) The character set used when creating the file Examples are: ASCII, Unicode, EBCDIC, UTF-8.
