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.

3.1. Data description
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, but the date is not available.

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 in to action on October, the 29th, 2023.
This new Agency faced the challenge of integrating the functions previously carried out by SEF, maintaining the regionalised service structure and introducing new digital strategies to facilitate and improve the processes of Residence.
The launch of AIMA embodies the separation of political and administrative functions, allowing the initiation of a series of new measures, functionalities and policies that will expand and improve the quality of access to services, reinforcing the security of processes and procedures and the trust and credibility of users and society in general.
When it was, the Aliens Service checked the entries in the system, eliminated duplicate data and incorrectly entered data.
Now, the people in charge of the data recording units supervise and control the work and record the data and its accuracy when it is recorded.
6.2. Institutional Mandate - data sharing
With the reallocation of SEF's attributions and responsibilities to Agency for Integration, Migration and Asylum, I.P. (AIMA) and the restructuring of the Portuguese system for managing border control, international protection and the documentation of foreign citizens, the following steps were
taken, with close cooperation is ensured between all the institutions:
- Border control; coordination and coordination of management, information and data bases and information systems relating to the movement of people and border control:
National Republican Guard (GNR)
Public Security Police (PSP);
Internal Security System - Border and Foreigners Coordination Unit (SSI/UCFE);
- Supervision and control of the stay of foreign citizens:
Public Security Police (PSP);
National Republican Guard (GNR);
- Responsibility for coordinating the work of the security forces and services among themselves and between them and the Institute of Registries and Notaries, I. P., and the AIMA:
SSI/UCFE
In practice, AIMA is responsible for assessment and decision of return cases.
GNR and PSP are responsible for the execution of return decisions.
7.1. Confidentiality - policy
Not applicable.
7.2. Confidentiality - data treatment
Not applicable
8.1. Release calendar
RESPER statistics are only published and disseminated in accordance with current legislation, which means that data is submitted annually.
The data is reliable and verified by the Statistics Director, to be extracted and analyzed on the new platform being designed at AIMA.
12.1. Relevance - User Needs
AIMA is constantly made available to INE - National Institute of Statistics, either by e-mail or on its platform with deadlines for sending.
This is necessary data and an obligation of the Portuguese state.
12.2. Relevance - User Satisfaction
Not applicable.
12.3. Completeness
See table 12.3. in annex ‘Quality report tables on student and researchers’.
12.3.1. Data completeness - rate
Not applicable.
13.1. Accuracy - overall
The accuracy of all the tables on residence permits is quite high, which means almost 100% accuracy.
The statistics reported almost accurately measure the target population, as provided for in Regulation (EC) No 862/2007(as amended by Regulation (EU) 2020/851) and as defined in the Operational Guidelines for residence permit statistics.
The target population, i.e. third-country nationals applying for a residence permit, is represented very accurately by the residence permit applications in the IND registers, and validated compilations of this data are made to fill in the mandatory tables.
The deviation is usually almost zero.

14.1. Timeliness
Given the transfer of responsibilities from SEF to AIMA, I.P., as well as the reduction in the number of staff, it can be said that this has led to a certain delay in the submission of some work.
But we have clearly made an extra effort and managed to submit everything almost on time, always with the support of our partners.

There are no sub annual statistics, only annual statistics.
15.3.2. Coherence - National Accounts
Not applicable.
15.4. Coherence - internal
All the statistics on residence permits are extracted from a database/SEF where we are now creating a new database/AIMA, which contains all the individual administrative data on residence permits, and all the statistics on residence permits are consistent with these of data extracted.

18.3. Data collection
Each data table is submitted according to the date indicated by EUROSTAT.
RESPER data is taken from the PT internal platform and after verification and validation, they are submitted to Eurostat via EDAMIS platform.
(Ever since the clear separation of duties between the police and the administration that came with the creation of AIMA, there have been clear tasks within the institution.
The statistics department is clearly responsible for working on, analyzing and submitting statistical data for the whole of AIMA.)
18.4. Data validation
A set of standardised validation checks are applied by Eurostat before publishing the data.
Data providers may transmit the data only in csv (comma separated value) templates (administered by Eurostat to Member States).
The new validation service infrastructure is built around two components performing validation operations: one for structural validation (called STRUVAL) and one for content validation (called CONVAL).
The validation rules below are checked to ensure the internal consistency of the data:
Variable codes and values of data are from a predefined set of accepted code-lists and format;
Statistics are confronted against other relevant data (e.g. a 'total' value of a given disaggregation (dimension) should equal the sum of the disaggregated data);
Investigating in consistencies in the statistics;
Analysis of size and sign of revision;
Verifying the statistics against expectations and domain intelligence;
Outlier detection.
18.5. Data compilation
Based on the national detailed figures transmitted by the national data providers, Eurostat derives European aggregates by applying common calculation method:
The geographical aggregation is done by arithmetical sum, when there are no missing values among the components of the respective geographical aggregate.
Otherwise, they are not calculated.
18.5.1. Imputation - rate

AIMA, I.P., is still updating its entire IT park and platforms due to the change in AIMA's structure.
But it's important to say that with the support we've had from our partners, everything has clearly worked out for the best.
