请教大侠：CDA帮助文档中一句英文的含义

guyucowboy

The entity playing the role is a person (Person class).
The entity scoping the role is an organization (Organization class).
哪位大侠帮忙看看，playing，scoping的含义，涉及entity的知识。我学CDA刚刚开始，不太明白，请大侠赐教，谢谢！

老包

从字面理解似乎为：
The entity playing the role is a person (Person class).（这实体担当的角色是人（类别属人类））
The entity scoping the role is an organization (Organization class).（这实体覆盖的角色是组织机构（类别属组织机构类））

但感觉两句语法成分不清晰，又无上下文，故仅供参考。

谢谢！
在这之前的一段是介绍authenticators的。
         A clinical document can have zero to many authenticators. While electronic signatures are not captured in a CDA document, both authentication and legal authentication require that a document has been signed manually or electronically by the responsible individual. An authenticator has a required authenticator.time indicating the time of authentication, and a required authenticator.signatureCode, indicating that a signature has been obtained and is on file.
然后是：
An authenticator is a person in the role of an assigned entity(AssignedEntity class).The entity playing the role is a person (Person class). The entity scoping the role is an organization (Organization class). (See here for a description of "player" and "scoper" role associations.)

点开here的连接可以找到对player和scoper的两句解释，我没看懂。
?/span>7.8 (0..*) ? Role:: player :: (0..1)?a href="#Entity-cls">Entity:: playedRole
"
?/span>7.9 (0..*) ? Role:: scoper :: (0..1)?a href="#Entity-cls">Entity:: scopedRole

之后的一段是：
A scoping organization can be part of a larger organization. Where there is a need to include whole-part relationships, the OrganizationPartOf role can be used. OrganizationPartOf.statusCode indicates the state of the whole-part relationship (e.g. "active", "terminated"). OrganizationPartOf.effectiveTime is an interval of time specifying the period during which the whole-part relationhship is in effect, if such time limit is applicable and known.

再次向大侠请教，谢谢！

多谢大侠回复！
明白了许多，非常感谢！
主要是我我对它里面“角色Role，扮演playing，覆盖scoping”概念所涉及详细的专业知识不太明白，刚刚入门，我在查下相关文档看看。
谢谢！

你的最新心得是什么？
这个人(entity)在这个机构(entity)担当authenticator(role)。人playing（担当）role，机构scoping（这个里的） role.
就好比
张三在我们医院当主任。张三(entity),我们医院(entity),主任(role)。

熟透番薯

张三是我们的科主任，外科教授。在一次心脏瓣膜置换术中，他充当了第一主刀医生,.....^_^

熟透番薯

如果说：

在一次即将进行的心脏瓣膜置换术中，张医生将充当第一主刀医生。

这是将来可能发生的，前者是已经发生的事件。
