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.

15.3. Coherence - cross domain
Non-EU migration flows estimated for demographic statistics are calculated using the Residence Permit data. Coherence between third-country national migration flows based on the usual residence definition and first permit was assessed by Eurostat. The relative difference for MT was below 5% and can be explained by differences in definitions and methods applied within the two domains. With regards to beneficiaries of asylum data, data for RP4 is extracted from the Asylum applicants database – this is the same source used to estimate flows for asylum seekers for demographic statistics. On the other hand stock figures for beneficiaries for asylum are not available.

18.5. Data compilation
Resident Permits: The information is compiled from an IT system which was launched in 2013. The data is extracted by the third-party company managing the system following a formal request for this data. The system is an administrative database used to register and manage Resident Permit applications. SP data are extracted from this system.
National Visas: The information is extracted from an IT system following a formal request for this data. The system is an administrative database used to register and manage National Visa applications. This data is used to add additional permissions to stay for the purposes for study following a policy change since April 2017. Persons applying for a course exceeding 90 days, except for higher-education courses recognised by MQRIC at Malta Qualifications Framework Level 5, or higher, shall have their authorisation to stay in Malta further extended by a national D-Visa (in place of a Residence Permit) for a maximum period of 365 days counting from the initial date of entry into the Schengen area. If the duration of the course exceeds 365 days and the student would have already exhausted the validity of the national visa, or his/her stay in the Schengen area already exceeded 365 days, the student must apply for a residence permit in order to extend his/ her stay in Malta. Where required, updates are made to table SP if a person is found to have been issued a VISA prior to the issuance of a SP in the same reference year and thus SP is a change in status and not first issued permit.
