Accessing Resource Previews
Resource previews provide small preview information for the Windchill RV&S Document and Node types. The Windchill RV&S OSLC Server provides the resource URI that the OSLC client applications can use to discover the link label and a resource icon. The OSLC client applications can then use the link label and icon to display the link in a meaningful way.
The Windchill RV&S OSLC Server supports the following URI with supported authentication for displaying the small preview of the Windchill RV&S Document and Node types:
GET <protocol scheme>://<server host name>:<server port number>/<context URI>/requirements?id=<Windchill RV&S Requirement ID>&preview=small
For example:
GET https://localhost:3001/oslc/r/requirements?id=15&preview=small (for a live item)
GET https://localhost:3001/oslc/r/requirements?id=15-1.0&preview=small (for a versioned item)
The OSLC client applications should set the Accept header to text/html when sending the GET request to the Windchill RV&S OSLC Server. In the response for such GET requests, the server provides HTML markups for the following default fields under the preview property as defined in the requirements-domain-mapping.json file:
ID
Created By
Type
State
Text
For more information on the requirements-domain-mapping.json file, see Mapping Requirements Domain Using OSLC Server.
The OSLC client applications can use these fields under the preview property to display a small preview of the Windchill RV&S Document and Node types.

PTC recommends using field types other than long text with rich content, Query Backed Relationship (QBR), and relationships field types for small previews.
