Custom objects of type DSV
    
     You can use objects of type DSV in ION File
      Connector and IMS Connector. DSV stands for Delimiter-Separated Values.
    When you register a DSV object schema in the Data Catalog, it is assigned a subtype. Based on the separator value that is provided in the schema, one of these subtypes is assigned:
- CSV - comma-separated values
 - TSV - tab-separated values
 - PSV - pipe-separated values
 - Other
 
A custom object of type DSV is defined by its name and a schema file.
An object name may contain these characters:
- Any standard letter in any language
 - Numbers 0-9
 - Underscore (_)
 - Hyphen (-)
 - Period (.)
