direct contact with the hximan rights bodies of the United Nations thus far. 102. Many agencies publish sets of core indicators. As we have seen, many core indicators viewed by one agency as such are not felt to be core indicators by other agencies. Added to this, many indicators seen as useful by some have been considered defective by others. These matters will require further exploration, especially in the context of indicator usage within the human rights field. Existing sets of core indicators can, however, assist human rights bodies in seeking the types and kinds of indicators which relate directly to the rights in question. 103. Providing core indicators for each of the rights of the Covenant is too complex and intricate a matter to be carried out at this stage. It has, however, been possible to suggest 10 general indicators which could be applied to initiate the integration of indicators more thoroughly into human rights activities. 104. Stringent criteria*will need to be applied to any selection process of core indicators, particularly if the intention is to utilize them to give economic, social and cultural rights greater precision and elaboration. Several of the more central criteria which should be employed are: (a) General and current availability; (b) International comparability between coxmtries and over time; (c) Direct relevance to the norms comprising economic, social and cultural rights; (d) Reliance on the indicator in question by at least two United Nations agencies; (e) The necessity of selectivity in the choice of indicators; (f) The existence of disaggregated indicators by various categories. 105. It also seems possible that indicators can assist (albeit in a limited manner) in determining violations of economic, social and cultural rights. This is especially true with regard to the non-discrimination clauses of the Covenant and the obligation to progressively realize these rights over time.
**Analysis**
The text appears to be discussing the development and application of indicators for economic, social, and cultural rights, with a focus on the United Nations and its agencies. The language used suggests a focus on abstract concepts and norms, rather than specific tangible resources or industries. The text also touches on the importance of international comparability and the need for selectivity in choosing indicators.
