简述开放存取自存档的涵义、存在意义、目前发展状态。认为开放存取自存档是学术信息交流的新的重要途径。分析开放存取自存档资源的版权问题、自存档知识库的互操作问题、自存档知识库的查找问题、自存档资源的元数据收割及检索问题。以美国麻省理工学院的DSpace系统为例,介绍自存档类型之一的机构知识库的应用状况及版权控制措施。
Briefly describe the meaning of open access and self-archiving, meaning of existence and current development status. It is believed that open access and archiving are new important ways to exchange academic information. Analyze the copyright issues of archiving resources from open access, interoperability problems from archived knowledge bases, finding problems from archived knowledge bases, and harvesting and retrieving metadata from archived resources. Take the DSpace system at Massachusetts Institute of Technology as an example to introduce the application status and copyright control measures of the institutional repository as one of the self-archiving types.
