Statistical standards applying to all indicators. In Section 3.1 the ENUMERATE Framework was described as covering the European memory institutions (museums, libraries, archives/records offices, audio-visual and film institutes, institutes with curatorial care for archaeology, monuments and sites, and some other/hybrid types of organisations). Below some issues about the breakdown of the full domain are discussed. Unit level issue The ‘memory institution’ is thus the principal entity we shall consider here. Definitions of this class/entity and its subclasses (e.g. museums and libraries) are in the main definition list. A thorny problem with institutions of this kind is that they can be complex organisations with often a hierarchical administrative structure that may obscure at what level indicators should be collected. The institution may be housed in one building, or it may be an aggregate of several physical sites under the umbrella of one administrative unit. Consider for example the question concerning an institution’s total annual budget. It is suspected that certain higher education libraries may have filled in the total annual budget for the entire library or even the entire university or polytechnic, whereas the intended amount should have been restricted to the budget of the cultural heritage related unit. It is proposed that the concept of ‘service point’ as the standard statistical unit should be used, under the condition that it should be recognisable as a named entity.9 Only where this is explicitly stated in the description of the indicator we recommend the use of the administrative unit. Part of the complications arising from the fact that institutions can be very dissimilar regarding their hierarchical organisation will be overcome by classifying institutions in a few size categories. This way it will be possible to do analyses on heritage institutions in the same size category. Classifications
