Should computer science indexing sites be considered in rating research?
Computer science is typically badly under-represented in the "traditional" citation indices, which do not consider conferences to be peer-reviewed publications.  As any computer scientist knows, that is a bad joke: many computer science conferences are much more stiffly reviewed and difficult to enter than most journals.  

It is for this reason that DBLP was created, to actually index relevant and reputable computer science publications.  I believe that DBLP should cover everything in ACM DL and IEEE Xplore, so getting just that accepted by the university should be sufficient.

Unfortunately, what you are seeing is another instance of a long-running and frequently waged fight.  Take heart, however, that this fight has already been won at most top institutions, and can be won at yours as well.
