Current code lives at https://svn.apache.org/repos/asf/tuscany/collaboration/GSoC-2011-Nirmal/. Few recognized todos : * References/Services that are directly linked with the composite (i.e. not with a component), should be addressed. * Wire should be flexible and should not draw over other artifacts, where it's not necessary. * Implementation.java elements of a component should be addressed more carefully. * Using "Promotion" for wiring should be addressed. * Should check with the spec and the community whether the all allowed/used ways(combinations) are supported. * Test cases * Provides corresponding HTML output. * Documenting layout algorithm.
