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.) |

This is an automatically derived data field, completely separate from the data found in North Plains pre-installed default field NP_file_info. This field can be used to identify durations for any media type, whether digital (or physical), and uses a more descriptive, understandable syntax to display the durations. Basically, the SMPTE timecode formating of XX:XX:XX is converted to XXhr XXmin XXsec |
|
The North Plains NP_file_info data that may include a duration for time-based media only presents those values in preselected layouts, and not as part of regular metadata entries. This is why UMAP has its own "Duration" metadata field that is totally under our control for data entry and presentation. |

This is an automatically derived data field, completely separate from the data found in North Plains pre-installed default field NP_file_info. This field can be used to identify durations for any media type, whether digital (or physical), and uses a more descriptive, understandable syntax to display the durations. Basically, the SMPTE timecode formating of XX:XX:XX is converted to XXhr XXmin XXsec UMAP does not anticipate the need to report durations down to the "frame" or "millisecond" level. Each unit of time (hours, minutes, seconds) has a suffix attached to the actual number associated with it. Do NOT use plural abbreviations for these designations for units of time. Use a SINGULAR abbreviation, i.e., No space should separate the number from its designation for unit of time. A single space should separate each unit of time, i.e., See the examples for other sample entries. |
