Frequency Rating (SDMX: CL_FREQ)

This classification provides a set of codes to indicate the "frequency" of the data (e.g. weekly, monthly, quarterly). The concept "frequency" can refer to several states in the production process, e.g. data collection or data dissemination. For example, a time series can be divided by annual frequency, but the data is calculated monthly. This classification was formally adopted on 4 December 2013. For more information about this classification and SDMX classifications in general (e.g. list of generic codes to express general concepts such as "Total", "Unknown", etc.; syntax for code creation; guidelines for the creation of SDMX classifications), can be found at this address: https://sdmx.org/?page_id=4345.本分类体系提供一组代码，用于标注数据的「频次（frequency）」（例如周度、月度、季度）。此处的「频次」概念可指代数据采集或数据发布等数据生产流程中的多种状态。举例而言，某一时间序列可按年度频次划分，但其实际计算频次为月度。 本分类体系于2013年12月4日正式被采用。如需了解本分类体系及SDMX分类体系的通用信息（例如用于表达「总计」「未知」等通用概念的标准代码列表、代码创建语法、SDMX分类体系编制指南），可访问以下地址：https://sdmx.org/?page_id=4345。
