METADATA ATTRIBUTES |
|
|
|
The metadata elements clustered under TECHNICAL: MEDIA TYPES, MANIFESTATIONS, RENDITIONS, LOCATIONS & IDS provide both formal and informal designations for the technical manifestations (or instantiations) in which a media item exists. |
|

1. MEDIA TYPE: Most often, a media item in the UEN Digital Media Service will be catalogued strictly as a single media type (a video, an audio, a document, image, or interactive object). 2. MEDIA MANIFESTATIONS: A media item may manifest itself as either a digital media item or a corporeal, physical item. 3. DIGITAL RENDITIONS ATTRIBUTES: A digital media item may have multiple file formats or renditions associated with its file type, each with its own set of attributes. These are reported as... TYPE (MIME) SIZE (file size) INFO (file attributes) 4. PHYSICAL RENDITIONS ATTRIBUTES: A physical media item may exist in multiple formats or renditions. End users need to know what that format is, as well as its location and any unique ID associated with the media item at that location. A summary data field draws its information from three attributes that are combined into single statements. PHYSICAL FORMAT: A physical media item may exist in multiple formats or renditions associated with the type of media it is in (VHS, Beta, DVD, CD, etc.) PHYSICAL LOCATION: Renditions for a media item may be available for download from a digital storage location or may be found in some physical location, building, department, library or shelf. For digital media items, the location is irrelevant because the digital asset management system handles the presentation and delivery of the asset to the end user through the web interface. For physical media items, location is relevant to the end user who may wish to acquire the asset. That location should be identified. LOCATION ID: The Location ID employs an unambiguous reference or identifier for a media item in a specific location. Best practice is to identify the media item with a string or number corresponding to an established or formal identification system if one exists (Dewey Decimal, Library of Congress, Amazon.com, etc.) |

Outside of specific digital asset management systems, metadata schemas must usually define all the individual technical attributes of a media item, particularly for digital instantiations. However, North Plains Telescope actually collects much of this information on its own when a digital file or rendition is associated with a metadata record. This information about the file may be exposed or hidden from the end user in thumbnail and summary views for media items. |

The attributes that are automatically collected under the North Plains label "INFO" depend on the File or MIME Type and include: FOR VIDEO... 1. Horizontal x Vertical pixel dimensions 2. Number of "tracks" 3. Duration (even though Duration is also reported elsewhere) Here is an example of the display: Info: 240 x 180 pixels, 2 tracks, 1:19 duration FOR AUDIO... 1. Number of "tracks" 2. Duration (even though Duration is also reported elsewhere) Here is an example of the display: Info: 1 tracks, 29:22 duration FOR IMAGES... 1. Horizontal x Vertical pixel dimensions 2. Color depth Here is an example of the display: Info: 1024 x 768 pixels, 24 bits/pixel FOR DOCUMENTS... 1. Horizontal x Vertical dimensions 2. Number of pages Here is an example of the display: Info: 1.4 x 1.8 inches, 3 pages |
