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.
Data collection on student and researchers (and other categories) is based on Article 38 of Directive (EU) 2016/801 on the conditions of entry and residence of third-country nationals in the framework of an intra-corporate transfer.
The following datasets are collected under this framework:
Authorisations for study and research by reason, type of decision, citizenship and length of validity (migr_ressrath)
Authorisations for long-term mobility of researchers by reason, type of decision, citizenship and length of validity (migr_ressrltm)
Notifications for research and study by reason, decision, citizenship and length of validity (migr_ressrntf)
Directive (EU) 2016/801 was transposed at national level on 2019
