BERLIN — Representatives from Syria’s political opposition presented a road map Tuesday that they hope will serve as a guide to the democratic transition of power in their country after the expected fall of President Bashar al-Assad.

Called “The Day After Project: Supporting a Democratic Transition in Syria,” the report was drawn up by 45 opposition representatives from political and religious organizations inside the country and in exile.

The group met over the past half-year for a series of secret conferences in Berlin to agree on several basic points they say are necessary to prevent their country from slipping into chaos should Mr. Assad leave power. Respect for human rights and a rule of the law constitute the underlying principles that are to guide the rebuilding of the state, including drawing up a new constitution, reforming the electoral system and changing social and economic policy.

“The project aims to be a response, in helping the Syrians, empowering them to take their destiny back into their hands, back from the rule of arms and terror, into the rule of law and democracy,” said Afra Jalabi, a political scientist based in Montreal who is a member of the project’s executive committee.
