These dates shall be fixed after, amongst other conditions to be met, the necessary implementing measures have been adopted by the Commission. These implementing measures cover SIS II aspects which, due to their technical nature, level of detail and need for regular updating, are not covered exhaustively by Decision 2007/533[JHA. These implementing measures include the SIRENE Manual which contains detailed rules for the exchange of supple- mentary information Supplementary information is infor- mation not stored in SIS II but connected to SIS II alerts, which is to be exchanged: in order to allow Member States to consult or inform each other when entering an alert; fol- lowing a hit in order to allow the appropriate action to be taken; when the required action cannot be taken; when dealing with the quality of SIS II data; when dealing with the compatibility and priority of alerts; when dealing with rights of access. Other implementing measures are protocols and technical procedures ensuring the compatibility of N.SIS II with CS-SIS; technical rules necessary for entering, updating, deleting and searching data on persons and objects; the specification of the special quality check to ascertain the fulfilment of a minimum data-quality standard by photo- graphs and fingerprints entered into the SIS II; technical rules on entering and further processing additional data for the purpose of dealing with misused identity and technical rules on the linking of alerts.

Since certain rules of a technical nature have a direct impact on the work of end-users in the Member States it is appropriate to combine them in one document. This Decision constitutes the necessary basis for adopting the SIRENE Manual and other implementing measures for the second generation Schengen Information System (SIS T0) in respect of matters falling within the scope of the Treaty on European Union (EU Treaty). Commission Deci- sion 2008/333/EC (?) adopting the SIRENE Manual and other implementing measures for the second generation Schengen Information System (SIS II) constitutes the nec- essary basis in respect of matters falling within the scope of the Treaty establishing the European Community (EC Treaty). The fact that the basis necessary for adopting the SIRENE Manual and other implementing measures for the second generation Schengen Information System (SIS TI) consists of two separate instruments shall not affect the principle that these implementing measures constitute one single document. Nevertheless, for the sake of clarity the annex should be reproduced in the Annexes to both Decisions. The United Kingdom is taking part in this Decision, in accordance with Article 5 of the Protocol integrating the Schengen acquis into the framework of the European Union annexed to the EU Treaty and to the EC Treaty, and Article 8 (2) of Council Decision 2000/365/EC of 29 May 2000, concerning the request of the United Kingdom of Great Britain and Northern Ireland to take part in some of the provisions of the Schengen acquis (?). Ireland is taking part in this Decision in accordance with Article 5 of the Protocol integrating the Schengen acquis into the framework of the European Union annexed to the EU Treaty and to the EC Treaty, and Article 6(2) of Coun- cil Decision 2002/192/EC of 28 February 2002 concern- ing Ireland’s request to take part in some of the provisions of the Schengen acquis (4).
