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

在这个项目的框架内，将建立一个技术基础结构，可以全面记录出版费用，并在标准化接口的帮助下使其公开获取。因此，需要开发一个元数据模式，使用该模式可以以结构化的形式记录和检索发布成本。这种元数据格式应该适用于科学机构产生的尽可能多的出版成本，因此不仅包括开放获取出版费用，即所谓的文章处理费（apc），还包括转换合同、会员资格和类似费用。这种标准化的数据格式使以自动化形式使用数据进行费用评价成为可能。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。出版费用的元数据格式将与国家和国际伙伴合作制定，因为它必须根据费用评价的目的满足不同的要求。在进一步的工作重点中，将在申请人的系统中开发和示范执行OAI接口，其中包括出版费用。这个OAI接口应该能够被其他系统使用，例如其他机构的机构存储库。通过这样一个接口，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Bielefeld大学图书馆的“OpenAPC”服务，也应该能够直接从机构收集出版物输出。第三个项目重点是扩展电子期刊图书馆，使其具有管理和显示关于开放获取出版费用或假设出版费用的信息的特殊功能。EZB的数据模型将以这样一种方式进行补充，即可以记录并显示EZB中特定于机构的协议，例如来自转换协议的成员资格或法规。此外，还可以输入特定机构所选期刊的出版成本假设信息。这些信息应该显示在EZB和各个日志中。此外，这些信息应该在API中以机器可读的格式提供。因此，EZB可以被所有参与机构用作向研究人员传达这些信息的中心平台。此外，计划为OpenAPC创建一个接口，以便能够为EZB使用该服务中聚合的数据。

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.
