TYPETYPE
“The nature or genre of the content of the resource”
GT Practice: Image.Moving (recommended for MPEG7).
For videos with sound. If the sound has meaning independent of the visual image, a second field is used: Sound
Genre is added as an independent field since the concepts of “Nature” and “Genre” are independent.
Simple: DC.Type

FORMATFORMAT
“The physical or digital manifestation of the resource. Format may include the media-type or dimensions (size, duration) of the resource”
Simple: DC. Format
Media-type
Best practice - use MIME
GT will use separate fields for the independent concepts, “media-type” and “dimensions”. CIMI practice - use this field for any item that cannot be experienced without machine assistance. To be congruent with other DC implementations, GT will use DC.Format for media-type (MIME or MIME extension) and size/duration only. All other physical description information will appear in adminstrative metadata.

IDENTIFIERIDENTIFIER
“An unambiguous reference to the resource within a given context”
Best Practice: “string or number conforming to a formal identification system” (e.g. URI, PURL, URL)
Simple: DC.Identifier
GT Practice: URL. For excerpts, segments, sequences, scenes or shots, the URL will end with the start time code of the first element. If SMPTE is available, it will be used. Otherwise, the notation will be hh:mm:ss, as determined by the playback device (e.g. VTR) or editing software (e.g. Adobe Premiere).

SOURCESOURCE
“A reference to a resource from which the present resource is derived.”
Best Practice: “string or number conforming to a formal identification system” (e.g. URI, PURL, URL)
Simple: DC.Source
CIMI practice is to use source when there is a direct parent/child relationship. GT will use only for direct parent/child relationships, including one-to-one format correspondence. Since the entire Carter interview is not digitized, there is no exact “parent” so the field is not used. The VHS interview appears in the DC.Relation field instead

DIGITAL VIDEO METADATADIGITAL VIDEO METADATALANGUAGELANGUAGE
“A language of the intellectual content of the resource”
Best practice: use RFC1766--a two-digit language code (e.g. en) taken from the ISO 639 standard, followed optionally by the country (e.g. en-uk). GT will use the country extension, because speech indexing programs in the future may be pronunciation-based.
Simple: DC.Language
Qualified: DC.Language->Dubbed
DC.Language->Subtitled
(the above are proposed extensions by GT. No working group currently exists for implementation.)
<meta name=“DC.Language” content=“en-us”>

RELATIONRELATION
“A reference to a related resource.” “An identifier of a second resource, and its relationship to the present resource.” Used to “reflect linkages” and “identify significant points in the hierarchy of surrogacy”
Best practice: “string or number conforming to a formal identification system” (e.g. URI, PURL, URL)
Simple: DC.Relation

COVERAGECOVERAGE
“The extent or scope of the content of the resource.” Includes spatial location (e.g. country, geographic co-ordinates or time code) and temporal period (period label, date or date range) or jursidiction (e.g. a named administrative entity)
Best Practice: Use a controlled vocabulary or standard, such as Getty Thesaurus of Geographic Names. SMPTE time code SMPTE 12M-1995 is preferred, but hh:mm:ss as derived from the playback source (VTR, etc.) or video editing software is acceptable when SMPTE is not readily available. Document the coverage source.

RIGHTSRIGHTS
“Information about rights held in and over the resource. Typically, a Rights element will contain a rights management statement for the resource, or reference a service providing such information. Rights information often encompasses Intellectual Property Rights (IPR), Copyright, and various Property Rights.”
Best Practice: Use a pointer (typically URL or URN) to a rights statement containing “accessibility, reproduction constraints, copyright holder, and/or inclusion of credit line”May vary according to type of material and type of restriction (e.g. Archival material; web-based class lecture)
