3. Management of standard and controlled terminology activities:  this  activity relates to maintaining and implementing enhancements of the  content and structure of the controlled terminologies that EFSA uses in the  remit of data dissemination and data collection/connection. EFSA standard  and controlled terminologies are lists of coded terms that can be organised  into one or many hierarchies that are used for reporting the values of  specific data elements or disseminate them according to specific domains.  This activity also includes support in designing, implementing and  maintaining ontologies, see: • https://www.efsa.europa.eu/en/efsajournal/pub/3424  catalogues  for  Standard Sample Description v.2 (SSD2), • https://www.efsa.europa.eu/en/data/data-standardisation,  • https://www.efsa.europa.eu/en/efsajournal/pub/3945. • the documented collection of requirements for the management of  standard and controlled terminology,  • requests for new terminologies, their implementation and maintenance  (e.g. the inclusion of new terms in existing catalogues, the revision of  catalogues terms, detection of duplicates, synonyms, deprecated terms  and errors, the mapping between different controlled terminologies), • implementation of structural changes to a standard terminology (e.g.  including new hierarchies or new fields),  • implementing and maintenance of ontologies,  • support in designing and implementing mappings of EFSA standard and  controlled terminology and structures vs. other existing data terminology  standards.  • the verification and testing of all functionalities offered.  4. Data flows for integration and transformation activities:  this activity  relates to the implementation of data integration flows to produce Extract  Transform Load (ETL), Extract Load Transform (ELT), Enrichment, Mapping  and Transformation processes and pipelines.  • the documented collection of requirements for the Data flows for  integration and transformation,  2  The aim is to produce fit-for-purpose scientific data tables and views to support  the analysis. A number of these procedures are already in place for handling  existing data collections, still there is the need for new data flows and  maintenance of existing ones. EFSA will design new data flows for new data  collections/connections and their related processes.  In the remit of this call for tenders and resulting contract, services/activities  foreseen comprise:  This  call  for  tenders  and  resulting  specific  contracts/order  forms,  services/activities foreseen comprise:  Support in designing and implementing mappings of EFSA standard and  controlled terms vs. other existing data terminology standards, together with  their structures is also part of the foreseen activities.
