[Dspace-general] DSpace `Dublin Core' | Date Issued | Date Range | How to represent

[Y.N.Ganesh]

Hi Richard,
   
  Dublin core suggests the encoding rules to be applied to data values.
   
  For any element that has dates it suggests the W3C-DTF  - http://www.w3.org/TR/NOTE-datetime 
   
  there are many values in the w3c scheme.
   
  We at NLB have tried to implement it based on information available during cataloging.
   
  for example - 
   
  YYYY format if the complete date of the resource is not available, but only the year
   
  YYYY-MM if the exact day of the resource is not available
   
  YYYY-MM-DD if the exact date is known
   
  So I agree with Mr Scott, DSpace might not validate the value, unless you have strict validation rule for the data values that have been input.
   
  to summarise, any format that falls in the w3c-dtf scheme should be good.

  Hi Richard,

It's up to you how you represent your values, you could use the DCMI 
Period or something simple such as "1930-1940". We tend to have the 
latter since that's what our users typically enter. The batch import 
process won't parse the values, as long as the document is valid XML the 
values will be accepted.

Scott.
