ATOM Entry Element

M/O

content

M

The content element shall contain a description of the proposed change.  This can be in the form of narrative text or a GML fragment indicating what the state of the feature should be.  If the proposed change is in the form of a narrative then the "type" attribute shall be set to "text/plain".  

If the proposed change is in the form of a GML fragment then the "type" attribute shall be set to "text/xml subtype=gml/X.X.X" where X.X.X indicates the version of GML being used and may include additional components for profiles.

For this specification, the GML version shall be "text/xml; subtype=gml/3.1.1/profiles/gmlsf/1.0.0/0"

id

M

The Id element shall be present.  The content of the Id element may be empty.  If the content is empty then the server shall generate an id (in the form of a uuid) for the entry.  If the content is not empty then it shall be an identifier for the entry generated by the client in the form of a uuid.  The server shall preserve client generated uuid's.Example: urn:uuid:26b3c614-b761-4f7c-a011-c2c15642cc3a.

Link

M

There shall be a single link element with the value of the "rel" attribute set to "targetServer" and the value of the "href" attribute set to base URL of the WFS to which this change is to be applied.

Example:
<atom:link
rel="targetServer"
href=http://demo.cubewerx.com/cubeserv/cubeserv.cgi?config=DEMO/>

This allows the change feed to be filtered for entries that apply to a particular server.
