THE CHALLENGE •Enrichment is straightforward •Harvesting from repository and return to repository its records if they have been “enriched” by deduplication and/or inference •Addition is less obvious •Based on relationships, in turn identified by inference algorithms •Must be augmented with notion of “trust” to enable “tuning” options in order to reduce false positive notifications Literature broker service 19
