Enhet for EØS-oversettelse er ansvarlig for oversettelse og revisjon (kvalitetssikring) av EU-rettsakter fra engelsk til norsk som skal innlemmes i EØS-avtalen, samt terminologiarbeid i den forbindelse. EU-rettsakter er juridiske tekster (hovedsakelig forordninger, direktiver og beslutninger) innenfor alle fagområder som omfattes av EØS-avtalen. Det utlyses totalt 6 rammeavtaler delt opp etter fagområdene det etterspørres kompetanse på (heretter omtalt som delområder). For hvert delområde vil det variere inntil hvor mange parallelle rammeavtaler oppdragsgiver har til hensikt å inngå. Samlet vil det kunne inngås 30 rammeavtaler.

    Rammeavtale for kjøp av oversettelses- og revisjonstjenester (1)
    description:
    Utenriksdepartementet v/Enhet for EØS-oversettelse inviterer til åpen anbudskonkurranse om kjøp av oversettelses- og revisjonstjenester. Enhet for EØS-oversettelse er ansvarlig for oversettelse og revisjon (kvalitetssikring) av EU-rettsakter fra engelsk til norsk som skal innlemmes i EØS-avtalen, samt terminologiarbeid i den forbindelse. EU-rettsakter er juridiske tekster (hovedsakelig forordninger, direktiver og beslutninger) innenfor alle fagområder som omfattes av EØS-avtalen. Det utlyses totalt 6 rammeavtaler delt opp etter fagområdene det etterspørres kompetanse på (heretter omtalt som delområder). For hvert delområde vil det variere inntil hvor mange parallelle rammeavtaler oppdragsgiver har til hensikt å inngå. Samlet vil det kunne inngås 30 rammeavtaler.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search_doffin lookup

  1. Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
  2. Check types, units, limits and ID formats in the parameter table.
  3. Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
