During The Open Group conference in Barcelona Gerben Wierda released his book Mastering ArchiMate Edition I. It contains an introduction to the ArchiMate language and documents his practical experience using the language within the financial domain. The book is available freely under a ‘begware’ license and I suggest that you donate or buy a licence if you use it commercially.
