The question raised regarding mapping turns on another question. In your Dublin Core record, are you describing the finding aid (if so map to <eadheader>) or are you describing the collection (if so map to <ead> or, more precisely, to <archdesc> elements)?

I'm interested in hearing justifications for mapping to either Dublin Core or MARC (or mixed practices using both). I understand the potential for using mapping to MARC for the creation of catalog records. What do people see as the purposes of mapping to Dublin Core? Do you consider it more far-reaching in its potential for future harvesting? If so, how? The EAD Cookbook recommends setting mapping to MARC21 in <ead> but the RLG guidelines seems to suggest that Dublin Core be used for <eadheader> and MARC for <archdesc>.
