Value = the awarded value the notice states, in EUR (converted at the notice date); framework agreements show none (their value is a ceiling, not spend). A notice with several winners or lots states one total for all of them: it is shown per notice in the table but left out of "value won alone". Matched to sioma.fi by company name, country and registry number where the notice states one.
