was considered very useful by INEXDA members (see Bender, Hausstein and
Hirsch (2018) for a more detailed description of the INEXDA metadata
schema).
At the third INEXDA meeting on 11 January 2018 at the Banque de France,
the INEXDA network welcomed the Banco de España and ECB as new INEXDA
members, increasing the number of INEXDA members from five to seven.
Furthermore, the Banco Central de Chile, Banco de México, Oesterreichische
Nationalbank, Central Bank of the Republic of Turkey and – for the first time, a
national statistical institute – Office for National Statistics UK attended the
meeting as guests. One notable outcome of the meeting was the consideration
of establishing working groups on different topics within the framework of
INEXDA (see section 4).
The fourth INEXDA meeting was held on 27 August 2018 at the BIS in Basel,
where Banco Central de Chile and Central Bank of the Republic of Turkey
participated as new members. Alongside the guests in attendance at the third
meeting, the Bank of Russia, Federal Statistical Office of Germany, Eurostat,
and the Swiss National Bank were attending the meeting as first-time guests.

3. INEXDA’s objective
INEXDA was established with the overall aim of facilitating the
international use of granular data for analytical, research and policy purposes
within the limits set by the applicable confidentiality regimes. This overall aim

can be further broken down into the following two, more specific objectives.
First, INEXDA will provide a basis for exchanging experiences on the
statistical handling of granular data that are accessible to external users.
Examples of “statistical handling” include the processes, methods, and tools
for data and metadata access, techniques for the statistical analysis of
granular data, procedures for data confidentiality and data security, and
procedures for output control. Second, INEXDA will provide a framework for
investigating possibilities to harmonise access procedures and metadata
structures, to develop comparable structures for existing data, and to further
foster the efficiency of statistical work with granular data.
The higher level of data disaggregation in the case of granular data is also
associated with an increased need for data protection. European and national
legal provisions regulate both the user group and the access channels to
microdata and oblige data providers and data recipients to maintain data
confidentiality at all times. Therefore, the overriding principle of the work of
INEXDA is compliant with the respective statutory secrecy and data protection

5 INEXDA’s objectives are outlined in the Memorandum of Understanding (MoU), which must
be signed by each member and is available on the websites of each member institution.
