openCost: automated, standardised delivery and open provision of publication costs and publishing agreements

在该项目的框架内，将建立一个技术基础设施，通过标准化界面，可以全面记录出版成本并使其公开。因此，将制定一个元数据模式，以便以结构化的形式记录和检索出版费用。这种元数据格式应该尽可能多地适用于科学机构产生的出版成本，因此不仅包括开放获取出版费用，即所谓的文章处理费用（APC），还包括转换合同，会员资格等费用。这种标准化的数据格式使得能够以自动化的形式使用数据进行成本评估。这促进了机构内部的成本透明度以及不同机构之间的成本比较。出版费的元数据格式将与国家和国际伙伴合作制定，因为它必须满足不同的要求，视成本评估的目的而定。作为进一步的工作重点，审调处将开发一个接口，并在申请人的系统中示范实施，其中包括出版费用。审调处的这一接口应能供其他系统使用，如其他机构的机构资料库。通过这样的接口，数据可以在一个机构内和跨机构合并，或者可以出于不同的目的进行查询。通过OAI-PMH，聚合器，如比勒费尔德大学图书馆的“OpenAPC”服务，也应该能够直接从机构收集出版输出。第三个项目重点是扩展电子期刊图书馆（EZB），使其具有管理和显示开放获取出版成本或假设出版成本信息的特殊功能。EZB的数据模型将以这样一种方式进行补充，即机构特定的协议，如成员资格或转换协议中的规定，可以在EZB中记录和显示。此外，还可以输入特定机构对选定期刊假设出版费用的信息。此信息应与各日记账一起显示在EZB中。此外，这些信息应在API中以机器可读格式提供。因此，所有参与机构都可以将EZB用作向研究人员传达这一信息的中央平台。此外，还计划创建一个OpenAPC接口，以便能够将该服务中汇总的数据用于EZB。

Within the framework of this project, a technical infrastructure will be created with which publication costs can be comprehensively recorded and made openly accessible with the help of standardised interfaces. Therefore, a metadata schema is to be developed with which the publication costs can be recorded and retrieved in a structured form. This metadata format should be suitable for as many of the publication costs incurred by a scientific institution as possible and thus include not only Open Access publication fees, so-called Article Processing Charges (APCs), but also costs from transformation contracts, memberships and similar. Such a standardised data format makes it possible to use the data in an automated form for cost evaluations. This promotes cost transparency within an institution as well as a cost comparison between different institutions. The metadata format for publication fees is to be developed in cooperation with national and international partners, as it must meet different requirements depending on the purpose of the cost evaluation. In a further focus of work, an OAI interface will be developed and implemented exemplarily in the systems of the applicants, in which the publication costs are included. This OAI interface should be able to be used by other systems, e.g. institutional repositories of other institutions. By means of such an interface the data can be merged within an institution and across institutions or can be queried for different purposes. Via OAI-PMH, aggregators, such as the service "OpenAPC" at Bielefeld University Library, should also be able to collect publication output directly from the institutions.The third project focus is to extend the Electronic Journals Library (EZB) with special functions for the administration and display of information on Open Access publication costs or the assumption of publication costs. The data model of the EZB is to be supplemented in such a way that institution-specific agreements such as memberships or regulations from transformation agreements can be recorded and displayed in the EZB. In addition, a possibility to enter information on the assumption of publication costs for a selected journal by a specific institution will be created. This information should be displayed in the EZB with the individual journals. Furthermore, this information should be made available in a machine-readable format in an API. The EZB could thus be used by all participating institutions as a central platform for communicating this information to researchers. Furthermore, it is planned to create an interface to OpenAPC in order to be able to use the data aggregated in this service for the EZB.
