Resolution

The data type for one of your fields is set to Date. This means that the metadata in this field must match the formatting rules below:

Supported Formats YYYY-MM-DD
YYYY-MM
YYYY
MM/DD/YYYY
MM/YYYY
YYYY-YYYY
2009-01-01
2009-01
2009
11/30/2008
11/2008
2008-2009
Supported delimiters between dates Comma (,) and
semicolon (;)
2008, 2009
2008; 2009
Leading spaces are okay but not required when using multiple dates YYYY; YYYY; YYYY
YYYY;YYYY;YYYY
2007; 2008; 2009
2007;2008;2009

If you don't want to have to use this format, change the data type to Text. Go to CONTENTdm Administration > Collections > Field Properties for the collection you're trying to upload the items to. Verify that the data type for each field is set to your preferred type.
