It appears that the purpose of the newly introduced attributes era:from and era:to is not clearly defined. The model already represents references to the first and second topological objects through the existing era:elementA and era:elementB, respectively (at least in the last version).
Given that era:from and era:to seem to serve the same function as elementA and elementB, could you please clarify their necessity in the model and intended use? as the previous still suits the model better.
thank you for the remark that there is no definition on the era:from and era:to properties. We will add those definitions and explain how they are used to link two linear elements.

Please have a look.
