Collaborative Research: DLESE Core Collections Services

AGI将为DLESE广泛馆藏提供资源编目。编目工作由拥有地球科学相关领域学位、课堂经验和编目、摘要和/或索引培训的GeoRef工作人员执行。通过这种直接编目工作，DLESE董事会收藏每年应增长1500-2000件。编目资源将来自以下以DLESE为基础的来源：通过评价核心服务的努力确定的资源；社区核心服务范例；以及通过DWEL项目确定但不包括在DWEL审查的收藏中的资源。在DLESE的最初开发过程中，元数据框架发生了变化。目前的DLESE编目系统增加了一些字段，其他字段在内容和应用上都发生了变化。正在考虑扩大国家教育标准在资源方面的应用。在该文件的开发过程中，已调整了受众字段。随着新框架的实施，地理空间参数将发生变化。目前正在审查地球系统科学(ESS)词汇，预计将于明年开始实施。一个单独的元数据研讨会将审议整个DLESE的元数据结构和回填需求。该讲习班的结果将确定回填的优先事项。鉴于在元数据讲习班结束之前不会就优先事项作出最后决定，对回填优先事项的合理假设是，至少对地球系统科学词汇和国家科学标准而言，回填将被视为必不可少的。到ESS词汇表完成时，大约有4000条目录记录需要回填ESS词汇表。

AGI will provide cataloging of resources for the DLESE Broad Collection. Cataloging is performed by GeoRef staff who have degrees in geoscience-related fields, experience in the classroom and training in cataloging, abstracting and/or indexing. The DLESE Board Collection should grow between 1500-2000 items per year through this direct cataloging effort. Resources for cataloging will come from the following DLESE-based sources: resources identified through the efforts of the Evaluation Core Services; Community Core Services Exemplars; and the resources identified through the DWEL project, but not included in DWEL's reviewed collection. The metadata framework has undergone changes during the initial development of DLESE. Some fields have been added to the current DLESE cataloging system and other fields have been changed both in content and application. Consideration is being given to expanding the application of the national education standards to resources. Audience fields have been adjusted during the development of the file. Geospatial parameters will undergo change with the implementation of the new framework. The Earth System Science (ESS) vocabulary is currently being reviewed and is expected to be ready for implementation to begin within the next year. A separate Metadata Workshop will consider the metadata structure and the backfilling needs across DLESE. Priorities for backfilling will be identified as a result of that workshop. Given that the final decision on priorities will not be made until the Metadata Workshop is complete, reasonable assumptions for backfilling priorities are that backfilling would be seen as essential for, at least, the Earth System Science (ESS) vocabulary and the national science standards. By the time the ESS vocabulary is complete, approximately 4000 catalog records would require backfilling for the ESS vocabulary.
