1、EDAM（Evernote Data Access and Management） 协议
数据模型（data model）由 rvice 管理the esntial 55
远程处理（remote procedures）从 rvice 返回和提交修改数据
通过 定义语⾔来描述数据模型和远程处理，⽀持所有流⾏语⾔
2、远程处理（remote procedures）
UrStore rvice ⽤户认证
NoteStore rvice ⽤于数据变更
英语四级考试作文万能句及万能模板3、数据模型
每个核⼼的 NoteStore 数据元都有⼀个GUID（Globally unique identifier），在创建时⽣成，不能修改，被API参考调⽤。
每个数据对象都有⼀个 USN（updateSequenceNumber），⽤于发⽣修改服务的时候。每次发⽣变更提交时会创建⼀个USN。USN 是⽤户名下唯⼀且单调递增变量，⽅便客户端判断同步。
Ur - ⽤户账户，⽤户名密码邮箱、个⼈属性、偏好
Accounting - 账务，服务级别：如上传次数/空间限制（uploadLimit）。
Notebook - 笔记本，每个⽤户账户可以有多个 notebook，note 需要存放在 notebook 中。有默认的 notebook - 不能删除最后⼀个 notebook。
Note - 超⽂本⽂档，ENML(Evernote Markup Language)格式，内嵌资源(images, ink, audio, PDF, etc.)，图⽚以内嵌⼆进制⽂件NoteAttributes - 系统定义的属性，如creation time, size, origin，⽤于搜索和过滤;
Resource - 资源⽂件，⼆进制数据块。类似于电⼦邮件的附件，每个资源可能有⼀组描述其定义的属性 ResourceAttributes.
SavedSearch - 保存搜索条件
资源内部使⽤MD5关联资源，如
<en-media type=”image/jpeg” hash=”9e107d9d372bb6826bd81d3542a419d6”/>
4、UrStore Service
UrStore Service API

checkVersion发送客户端版本号给服务，并获取兼容响应。
authenticate发送⽤户名和密码给服务，并获取成功的令牌信息。
refreshAuthentication发送⼀个将要到期的令牌给服务，并获取⼀个新的令牌。
getUr根据令牌返回⼀个⽤户。
getPublicUrInfo返回⼀个⽤户的公开信息。
