Brief overview: Description of feature Is a feature for tagging metadata records with arbitrary "flags” to allow external partners to organize collections of metadata. This would allow partners to create collection subsets highly customized to a specialized discipline or interest outside of what is defined in metadata. Partners creating collections of metadata need not be involved with the metadata authoring process and no changes are required on the authors part. These tags are not publicly displayed in any web interface. The tags can be used in creating IDN portal subsets or any other searches on IDN. 3
