我正在尝试更改研究人员实体用于创建配置文件的默认元数据。我按照此页面上的说明进行操作：https : //wiki.duraspace.org/display/DSPACECRIS/How+to+collect+data+about+CRIS+entities并且正在创建配置文件，但现在出现内部服务器错误.
我更改了 /dspace/config/dspace.cfg 中的以下几行
从
choices.plugin.dc.contributor.author = RPAuthority
choices.presentation.dc.contributor.author= lookup
authority.controlled.dc.contributor.author = true
至
choices.plugin.dc.contributor.myorganizationauthor = RPAuthority
choices.presentation.dc.contributor.myorganizationauthor= lookup
authority.controlled.dc.contributor.myorganizationauthor = true
这是日志：

我找到了一个解决方案，感谢 Andrea Bollini 的帮助。
发生的事情是当我改变这个时：
choices.plugin.dc.contributor.author = RPAuthority
choices.presentation.dc.contributor.author= lookup
authority.controlled.dc.contributor.author = true
对此：
choices.plugin.dc.contributor.myorganizationauthor = RPAuthority
choices.presentation.dc.contributor.myorganizationauthor= lookup
authority.controlled.dc.contributor.myorganizationauthor = true
我还删除了 dc.contributor.author 所需的 ChoiceAuthority 插件。为了修复它，我需要添加这段额外的代码。
choices.plugin.dc.contributor.author = AuthorAuthority
choices.presentation.dc.contributor.author= lookup
authority.controlled.dc.contributor.author = true
在“plugin.na:med.org.dspace.content.authority.ChoiceAuthority = \”下，我需要注册我的新ChoiceAuthority“AuthorAuthority”它应该是这样的：
##### Authority Control Settings #####
plugin.named.org.dspace.content.authority.ChoiceAuthority = \
org.dspace.app.cris.integration.ORCIDAuthority = RPAuthority,\
org.dspace.content.authority.ItemAuthority = AuthorAuthority,\
...
