Nota Bene: It is highly recommended that the user of this document read the Introduction to obtain a fuller understanding of Dublin Core and its implementation.
It is very important that documents have the date of their creation. How often have instructors stated that articles should be current, or within the last 5 years. More often than not, the perfect Web document will not have the date of its creation mentioned anywhere. By providing a date, it would be helpful not only to the information seekers but also to catalogers and indexers of these documents.

Dates can be entered in a variety of ways. Most of the standards are very similar to each other. The most commonly used standard used has been the ISO31. This probably because of its simplicity compared to the default SCHEME. Its structure is merely the year, month and day separated by dashes.
<META NAME="DC.date" CONTENT="(SCHEME=ISO31) 1997-07-26">
ANSI.X3.30 and the FGDC are structured the same but omit the dashes.
<META NAME="DC.date" CONTENT="(SCHEME=FGDC) 19970726">If the document has been modified after it was published in electronic form, the TYPE qualifier modified should be appended to the DC.date value.
<META NAME="DC.date.modified" CONTENT="(SCHEME=ISO31) 1997-08-01">The default value as of this writing is very lengthy and complex. The structure is best represented visually as a whole.

The average user would not even remotely want to input a date with this kind of detail, the main reason it will not be explained any further here.
