different roles

Many documentation dialects include mechanisms for connecting people and organizations to metadata records. There are two general approaches to these connections. The first involves including the roles of the people in the names of the metadata element's. For example, the NetCDF Attribute Convention for Data Discovery includes fields titled creator_name, creator_email, and creator_url. This approach makes it difficult to standardize because new standard elements must be added in order to add a new role, i.e. processor_name, processor_email, processor_URL. The second approach centers around a generic description of a person or an organization that includes an attribute that gives the role they play with respect to the resource being documented. This approach allows additions by extending the list of roles. See NetCDF, HDF, and ISO Metadata for more details on this approach.
