Atom提要是共享频繁更新内容的一种有用方法;users can subscribe to a feed and automatically have access to the most up-to-date data.INSPIRE* data download requirements can be met using ATOM feeds,and a number of organizations are doing so.
FME'sgeorss/rss提要阅读器和编写器支持RSS和Atom,允许用户读写Atom提要。In this demo,两个工作区与FME服务器结合使用以创建Atom提要:
1)一个工作区创建Atom提要,并应与数据流服务一起发布到FME服务器。When this workspace is run via,它返回RSS/Atom提要,其中包含指向可下载的Inspire数据层的链接。
2)如果用户从Atom服务为Inspire数据层选择下载链接,this triggers the second workspace to run and return the XML via the Data Streaming service.
Note: when the ATOM feed workspace is run via the Data Streaming service,将显示下载数据的链接。如果在Firefox或Internet Explorer中查看数据,则自动呈现Atom源。Google Chrome does not automatically render ATOM feeds but there are browser extensions available to do this.
为了完成这个练习,您还需要下载WMS Inspire数据覆盖威斯敏斯特和Brent伦敦区。

从导航窗口编辑私有参数值
Obtain a token and note its expiry date
http://: /fmedatastreaming/inspire/inspireatomfeed.fmw?
访问Atom订阅源服务的URL
默认情况下,运行工作区并通过直接URL传输Atom提要需要身份验证。This link can be made publicly available without the need for authentication by configuring the security settings of the INSPIRE repository to be open to the fmeguest account.
1.In FME Server,单击左侧菜单中“管理>安全”下的“角色”。
Location of Security in Menu bar
2。Select the fmeguest role
3.在“存储库”下,授予对Inspire文件夹的读取/运行权限。同时确保在服役期间,Data Streaming is allowed.
