Additional Functionality Using the Cloud

The Cloud Services provide the facility of connecting to and using models over a secure http connection. They also make it possible to use three further facilities on or within your models:

  • Open Services for Lifecycle Collaboration (OSLC)
  • Reusable Asset Service (RAS)
  • Scheduled Tasks


OSLC is an initiative to provide easier integration between Requirement Management tools. It uses HTTP to list, add, modify and delete requirements. The service provider definition to direct any OSLC client to is:


For example, if you were connecting to a server running on your own machine using the default settings, the connection would be:


Reusable Asset Service (RAS)

The RAS portion of the Cloud Server helps you to define Packages that can be used in any model. When a Package is requested, Enterprise Architect and the Cloud Server will track cross-Package dependencies and make available everything required by that Package.

Scheduled Tasks

The Cloud Server includes optional support for running time-based updates to data. Currently, this is applied to updating a Time Series chart automatically to provide a dynamic view of how a model is changing over time. You can set different time scales for these updates, such as daily, weekly or monthly.


  • This facility is available through the Corporate, Business and Software Engineering, Systems Engineering or Ultimate editions
