2.1简介OpRa的工作范围是定义作为PT定量分析使能因素所需的最小公共交通原始数据集。考虑到这一复杂领域涉及的所有几个方面，为实现这一目标，工作已通过以下阶段进行:1） 评估；2） 用例定义和分类；3） 指标定义；4） 原始数据标识。OpRa的工作不涉及服务质量测量和报告领域:服务质量分析当然将使用OpRa提供的数据，但质量定义仍然是公共交通管理局和公共交通运营商之间的一个合同级问题，或者是运营商对纯私人服务的内部选择。OpRa主要只报告无偏见的实际数据（即测量或观察），以共享和可理解的方式描述和汇总。本文件中详细记录的OpRa工作符合欧盟指令2010\/40。特别是，它涉及欧盟2017\/1926授权条例第4条，涉及历史数据。OpRa建议对基于基础概念数据参考模型Transmodel EN 12896的历史数据补充NeTEx（专用于静态计划信息），类似于欧盟2017\/1926号授权法规对静态计划信息的要求。(.)

2.1 Introduction The OpRa work scope is the definition of a minimum set of Public Transport raw data needed as PT quantitative analysis enabling factor. To obtain this considering all the several aspects involved in this complex domain, the work has been conducted through the following phases: 1) assessment; 2) use cases definition and classification; 3) indicators definition; 4) raw data identification. OpRa work does not go into the field of service quality measurement and reporting: service quality analysis will of course use data provided by OpRa, but quality definition remains a contractual level issue between a Public Transport Authority and a Public Transport Operator or an operator’s internal choice for a purely private service. OpRa mainly only reports unbiased actual data (i.e. measured or observed), described and aggregated in a shared and understandable way. The OpRa work documented in detail in this document is coherent with EU Directive 2010/40. In particular, it relates to the Article 4 of the Delegated Regulation EU 2017/1926, as regards the historic data. OpRa proposes to complement NeTEx (dedicated to the static scheduled information), for the historic data based on the underlying conceptual data reference model Transmodel EN 12896, similarly to the requirement of the Delegated Regulation EU 2017/1926 referring to the static scheduled information.
