DEFINITION: Data Management Service ABB is an Application Service enabling the exchange of structured data under a source schema and transforming it into a target schema, so that the target data is an accurate representation of the source data. Data repository exchange service allows data to be shared between different application programs. Source: Guardian (https://digitalguardian.com/blog/what-data-repository) INTEROPERABILITY SALIENCY: IoP Dimension: Structural IoP The Data Management Service ABB  is salient for technical interoperability because it provides and shares the functionality for the share of data: "Legislation requires that decisions and data are stored and can be accessed for a specified time. This means that records and information in electronic form held by public administrations for the purpose of documenting procedures and decisions must be preserved and be converted, where necessary, to new media when old media become obsolete. The goal is to ensure that records and other forms of information keep their legibility, reliability and integrity and can be accessed as long as needed subject to security and privacy provisions." EXAMPLES: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): Oracle Data Exchange The Data Exchange Service provides several access points to the Event Repository, allowing the user to perform queries on these events: - The Query Subscription Administration Console configures the Data Exchange Service to create queries and periodically deliver query results to designated receivers (HTTP, JMS, and AS2). The Console can also test queries before subscribing, displaying user-readable events in XML format. - A SOAP Web service allows programmatic queries. This SOAP service is based on the technically complete, but not formally ratified as of October 2006, EPCglobal EPC Information Services (EPCIS) Version 1.0 Specification.EPCglobal EPCIS 1.0 Working Draft. https://docs.oracle.com/cd/E13197_01/rfid/enterprise_server/docs20/epcis/data-exchange.html
