New items activated in the SLUB catalog in 2025

The data set is available as a gzip-compressed, line-delimited JSON file and contains the 20,527 documents with new items activated in the SLUB catalog in 2025 with the fields id (document identifier), rsn_id_str_mv (record serial number), de14_new_item_act_date (timestamp) and de14_new_item_act_date_mv (timestamps). The id consists of a source id and a record id according to the scheme {source_id}-{record_id} and enables the detailed view of a document to be retrieved using the following URL scheme: https://katalog.slub-dresden.de/id/{id}. Example: https://katalog.slub-dresden.de/id/0-1929313942. Since the documents in this data set originate exclusively from the Southwest German Library Network (SWB), the source id is always 0 and the record id corresponds to the Pica Production Number (PPN) of the K10plus. The value for the field rsn_id_str_mv is based on the RSN field of the corresponding title in the Libero Library Management System, it is additionally prefixed with DE-14, i.e. the ISIL identifier of the SLUB. The multi-valued string field is a dynamic field according to VuFind's Solr index schema. The RSN value also enables the detailed view of a document to be retrieved using the following URL scheme: https://katalog.slub-dresden.de/rsn/{rsn}. Example: https://katalog.slub-dresden.de/rsn/17235034. The values for the fields de14_new_item_act_date and de14_new_item_act_date_mv are based on the NewItemActDate field of the corresponding items in the Libero LMS. While the multi-valued field de14_new_item_act_date_mv contains all dates from the year 2025 that could be assigned to a document, only the most recent date is specified in the field de14_new_item_act_date. Both fields are dynamic fields according to VuFind's Solr index schema. Until January 2021, the date values were used to display a list of new acquisitions on the SLUB website.本数据集以gzip压缩、按行分隔的JSON文件形式提供，共收录20527条文献记录，对应2025年萨克森州立与大学图书馆（SLUB）馆藏目录中新增激活的馆藏条目。数据集包含以下字段：id（文献标识符）、rsn_id_str_mv（记录序列号）、de14_new_item_act_date（时间戳）与de14_new_item_act_date_mv（多值时间戳）。id字段按照{source_id}-{record_id}的格式由来源标识符与记录标识符组合而成，可通过以下URL模板检索对应文献的详情页：https://katalog.slub-dresden.de/id/{id}，示例链接：https://katalog.slub-dresden.de/id/0-1929313942。由于本数据集的文献仅来源于西南德意志图书馆联盟（SWB），因此来源标识符固定为0，记录标识符对应K10plus馆藏的Pica生产编号（PPN）。rsn_id_str_mv字段的值基于Libero图书馆管理系统（Libero Library Management System）中对应馆藏的RSN字段，且额外添加了前缀DE-14——即萨克森州立与大学图书馆（SLUB）的ISIL标识符。该多值字符串字段属于VuFind的Solr索引架构中的动态字段。通过RSN值亦可通过以下URL模板检索对应文献的详情页：https://katalog.slub-dresden.de/rsn/{rsn}，示例链接：https://katalog.slub-dresden.de/rsn/17235034。de14_new_item_act_date与de14_new_item_act_date_mv字段的值均来源于Libero LMS中对应馆藏的NewItemActDate字段。其中多值字段de14_new_item_act_date_mv包含可归属至某条文献的所有2025年相关日期，而de14_new_item_act_date字段仅记录最新的日期。两个字段均属于VuFind的Solr索引架构中的动态字段。2021年1月以前，上述日期值曾用于在SLUB官网展示新增馆藏列表。
