Hi,
there are some ways to get the properties (short desc, Alias, etc.) of requirements or general of elements.
You may write an addin or script which uses the EA standard API to get access to it.
You may write a query to get the wanted information. If you use the query:
select * from t_object where object_type = 'Requirement'
you will see all the available columns or a requirement. You may change the object_type to get other element types.
To get more eloborate information you have to dig a little deeper into the tables or API.
A great help are Thomas Kilians ebooks.
For importing information into EA have a look in the community. Geert for example has a great tool to import from Excel.
