WireCloud provides integration with several of the generic enablers provided by by FIWARE. Some of those GE has been integrated in the core of WireCloud by means of providing a plugin for FIWARE. This core integration provides support for the following GEs:

• IdM
• WStore
• Orion Context Broker
• Object Storage

In any case, widgets and operators can make use of other GE as some of them does require special support from WireCloud:

• Kurento
• CKAN
• ...

This documnet will describe what can you expect from the integration of each of these generic enablers, from the perspective of an end-user and from the perpective of a developer.

• IdM is integrated directly in Wirecloud, there is no API for making request to the IdM server from widgets/operators
• This integration provides the following features:
  • User authentication using IdM credentials
  • Support for using the obtained OAuth2 token for making requests to three-party services (including from widgets/operators)

• WStore is integrated directly in WireCloud, there is no API for making request to the WStore from widgets/operators
• Requires IdM integration for using user credentials when connecting with the WStore
• This integration provides the following features:
  • Allow to browse WStore offerings
  • Support for acquiring and installing offerings
  • Support for uploading Wirecloud components to the WStore. Enabling you to easily create offering using those resources

• Orion Context Broker subscriptions/notifications requires what is called ngsi-proxy (You have to deploy it for custom deployments, but there is a global instance at FIWARE Lab)
• See the OrionStarterKit offering available on FIWARE Lab for obtaining a set of generic widgets/operators and some example mashups using the Orion Context Broker.
• Those widgets/operators will be enough for simple usages. In any case, WireCloud provides JavaScript API that can be used for developing new widgets/operators:
  • This API provides integration for authentication through the IdM
  • Supports creating and modifying entities, querying, subscriptions, etc.
  • Automatically cancels subscriptions created by widgets/operators when they are unloaded

• WireCloud provides a JavaScript API:
  • Has minimal support for querying KeyStone services
  • This API provides integration for authenticating through the KeyStone server using tokens obtained from the IdM server
  • Supports uploading objects, download objects, deleting objects, listing containers, creating containers and deleting containers

Kurento

• Kurento is a WebRTC media server and a set of client APIs making simple the development of advanced video applications for WWW and smartphone platforms.
• See the KurentoStarterKit offering available on FIWARE Lab for obtaining a set of widgets already using Kurento.
• You can develop widgets using Kurento without requiring special support from WireCloud.

CKAN

• CKAN is a powerful data management system that makes data accessible – by providing tools to streamline publishing, sharing, finding and using data. CKAN is aimed at data publishers (national and regional governments, companies and organizations) wanting to make their data open and available.

• See the CKANStarterKit offering available on FIWARE Lab for obtaining a set of widgets/operators already using CKAN.

Cosmos

• Comsos is planned to be integrated soon. This integration will provide support for:
  • using the webHDFS filesystem (uploading and downloading data being consumed and produced by Cosmos)
  • Integration with the Hive service: queue new jobs and retrieving their results
