However, as will become clear, even this approach will not produce a straightforward sector assignment as found in the Frascati manual. Problems increase when considering 7 In Appendix A the total list of SQL queries with keywords used for generic and case oriented rules are given. In addition, Appendix B provides an overview of an additional list of (exact) case oriented rules (exact matching) that have been included in the methodology.
