Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

6.1. Institutional Mandate - legal acts and other agreements
The new Agency for Integration, Migration and Asylum in Portugal, also known as AIMA,I.P., came into action on October, the 29th, 2023.
