The easiest way to create the topology is to do it in catalog.
You'll have to right click the feature dataset, point to new, topology. Once it's created, right click and go to properties. From there, you can add your rules such as, polylines must be covered by polygons and polygons must be covered by polylines.
Be sure your data is not in use.
You may want to read up on the local government model and parcel fabrics. You'll need to DL this information and use their staging data Tax Parcel Editing | ArcGIS for Local Government be sure you enable the local government model on the new fabric.
It's probably easier this way than trying to create it from scratch. You'll load your data (polygons and polylines) in type 6/7 and validate that topology (rules are set).
See here for my issues and solution to not being able to load the type 7 data into fabric. I too am learning how to use fabric.
