Entry checklists

To help authors create entries (and to improve old entries) we could have entry checklists. For example, for entries defining a topological property (say compact) there are a natural questions that should be answered:

• How is the property preserved in subspaces?
• How is the property preserved under maps?
• Is it preserved under unions, intersections, products (finite, countable, arbitrary?)

On the other hand, for matrix operations (say matrix inverse) we could have another checklist

• Special cases for small matrices (n=1,2, 3) and diagonal matrices?
• What happens with eigenvalues, eigenvectors, norms, characteristic polynomial?
• Calculation rules (sum, product, Kronecker product, derivative)?

This is a lot like the idea of a "frame" in AI. A similar idea was used in the old mac program HyperCard. --jcorneli
