Title

Source Definition: A name given to the resource.
Source Comments: Typically, a title will be a name by which the resource is formally known.
DC-Ed Comments: Supply a common title appearing on or associated with the learning resource. Either a title or identifier is mandatory. If no title is available, best practice is to give a constructed title, derive a title from the resource, or leave blank.

Type

Source Definition: The nature or genre of the content of the resource.
Source Comments: Type includes terms describing general categories, functions, genres, or aggregation levels for content. Recommended best practice is to select a value from a controlled vocabulary (for example, the DCMI Type Vocabulary [DCMITYPE]). To describe the physical or digital manifestation of the resource, use the Format element.
DC-Ed Comments: Use a controlled list and identify the source with encoding scheme. Use lists that emphasis the learning or educational nature of resources over the format of a resource (e.g. problem set, tutorial, case study). Recommended that at least one value from DCMI-Type be supplied for a high level category. For educators and trainers, lesson plans or activities with stated learning objectives are essential as well as assessments to measure progress towards objectives. Suggest adding the words lesson (or learning material??) and assessment as potential DC vocabulary terms.

Valid

Source Definition: Date (often a range) of validity of a resource.

DC-Ed Comments: The use of a single date is ambiguous. It is possible to have a valid from date and no valid to date and vice versa. It may be appropriate to change valid to validFrom and add a validTo.

Recommend using ISO 8601:2004.
