Teamwork Cloud adds OSLC support and now exposes model element data following OSLC Architecture Managemenet (AM) (http://open-services.net/ns/am#) vocabulary. Along with core OSLC services provided in Teamwork Cloud, this enables smooth integration with other OSLC-compatible tools by linking resources in Linked Data fashion. Here are the key points behind current Teamwork Cloud OSLC provider implementation:

  • OSLC root services document URI can be found using the following pattern - http(s)://TWC_IP:PORT/oslc/rootservices.
  • Each of the model elements is exposed using the following URI pattern - http(s)://TWC_IP:PORT/oslc/am/{projectID}/{elementID}.
    *Note: the elementID here is an Element Server ID.
  • We expose the following model element properties:

  • Currently, querying services are not supported. Model data can only be read through OSLC services and editing capabilities are not supported.

  • We offer OSLC UI previews through integration with Cameo Collaborator for Teamwork Cloud. For more information, check Publishing an OSLC resource.
  • We provide OSLC delegated dialog support via Selection Dialog service for navigating the model tree and linking to AM resources from external tools.

OAuth 1.0a authentication

To ensure secure access to server resources via OSLC, OAuth 1.0a authentication protocol is used.

OAuth 1.0a requires consumer key and secret to be known before starting the authentication process flow. These can be created through Teamwork Cloud Admin as described in Managing OAuth consumer keys.

Alternatively, a pair of consumer key and secret can be generated manually via a service exposed in the root services document. The following HTTP POST request should be made to a consumer key generation service (jfs:oauthRequestConsumerKeyUrl):

HTTP request body
{
  "name": "consumerNameGoesHere",
  "secret": "OAuthSecretGoesHere"
}


HTTP response body
{
  "key": "generatedConsumerKeyShouldBeHere"
}

Note, that keys generated following this approach will still need to be approved by an administrator through Teamwork Cloud Admin console.
