This page contains the project plans for the Eclipse Lyo project. The first part of the plan describes the various components of Lyo and the currently planned enhancements to functionality. This plan is subject to changes based on community participation and the importance of proposed functionality to the community - we encourage anyone interested to participate. The planning process will be as open as possible and this plan will be updated as it changes. Please provide feedback on the lyo-dev@eclipse.org mailing list.
