As processor (MN, CN) of DataONE content, I need to discover if a particular object format should be treated as science metadata.

• Create a registry of object formats

• Each entry of the registry should indicate what roles a particular object format can have.

Using a registry will help avoid creating large lists of hard coded values and ugly case statements such as:

boolean scimeta = false;
switch (sysmeta.getObjectFormat()) {
case EML_2_1_0: scimeta = true; break;
case EML_2_0_1: scimeta = true; break;
case EML_2_0_0: scimeta = true; break;
case FGDC_STD_001_1_1999: scimeta = true; break;
case FGDC_STD_001_1998: scimeta = true; break;
case NCML_2_2: scimeta = true; break;
}

Suggest a data model something like:

objectFormatList
format*
objectFormatNamespace
objectClass+ [data/metadata/fooClass]

and a method such as

ObjectClass[] getObjectClass(objectFormatNamespace)

to indicate the roles of a particular object format.

Should be implemented as part of the CN functionality.
