The UbiCompForAll project provides notation and tool support to the end users for creating service compositions. Among other options, we have been working on a tool that runs on web browsers. The advantage of a web browser-based tool is its ability to run on mobile devices supporting various operating systems. It also facilitates using the tool directly from a server even without installing it, in addition to the possibility of easy installation on the user’s device.
Each service is associated with a description corresponding to a meta-model, which works as the basis for the notations and development of all UbiCompForAll composition tools. The browser provides a palette consisting of icons representing all the services available at run-time. The users use that palette to select and configure services in order to create the composition. Data transfer between services is indicated by a connector between them. A single connector is used to handle any number of data dependencies between two services. Based on the service description the editor provides the users the facility to choose the up-to-date data.
An initial version of the tool was demonstrated mid-september 2010. A fully-functional prototype supporting the initial simplified composition notation developed in the project, will be available in November 2010.
