This study proposed an integrated management system model of researcher identifiers using the ISNI(International Standard Name Identifier) that can prevent duplicate issuance of identifiers and can be used to reorganize the authors' information. We looked at the metadata structure and management system of the ISNI that can be applied in various fields among identifiers. And we have designed the integrated ID system and system model that can manage the identifiers issued by each institute based on the ISNI. This model consists of data structure layer, platform layer, application layer, management and security layer (4 layers) and we have presented some of the key features and issues to consider when managing the integrations.
