Conversion is the process by which data is transformed from one form of representation to another without losing meaningful content. In the energy sector, conversion is ubiquitous: EDIFACTElectronic Data Interchange For Administration, Commerce and Transport - UN standard for electronic data exchange. messages are converted to JSONJavaScript Object Notation - lightweight data format for data exchange between systems, standard in REST APIs. for modern APIs, XMLExtensible Markup Language - universal markup language for structured data, standard in Elhub's Ediel messages.-based ElhubNational hub for metering data and market processes in the Norwegian electricity market. messages are translated to RESTRepresentational State Transfer - architectural style for APIs based on HTTP and resource-oriented design. calls, and legacy databaseOrganised collection of structured information stored and accessed electronically - foundation of all digital systems. formats are migrated to new data models. Conversion occurs in three contexts: format conversion (XML → JSON, CSV → Parquet), schema conversion (old data modelFormal representation of data structure, relationships and constraints - foundation for database design and system messages. → new data model) and protocol conversion (SOAPSimple Object Access Protocol - XML-based messaging protocol used in enterprise integrations, including Elhub. → REST). TvimenningOld Norse meaning 'two bound together' - one who solves a task shoulder to shoulder with another. carries out conversion assignments as part of modernisation and integration projects - typically when transitioning to a new KISCustomer Information System - the core system at power suppliers and grid companies for customer management and billing., new MDMMeter Data Management - system for collection, storage, quality assurance and distribution of metering data from the electricity grid. or new cloud platform. A successful conversion requires thorough mapping of source data to the target format, handling of missing and invalid values, and post-conversion verification against the source data.
