OYSTER_Reserved_Words

During the design of the OYSTER system, it was decided that there is a need for a set of reserved words that can be used to specify special attribute types in the OYSTER Source Descriptor. In Figure 12, The @RefID keyword is used as the Attribute value for the item named IdentityID. This specific keyword informs OYSTER that this attribute is the unique identifier for the references in the source input file. OYSTER will exclude this value when creating OYSTER IDs but will use it to allow for future file tracking along with the source name specified.

A complete list of OYSTER reserved words, and their uses, can be located in the OYSTER Reference Guide.
