  1. We compare existing indexes containing information about resources. We considered several classification criteria: i) automatic index generation, ii) whether or not the index indexes external resources, iii) whether the index interface provides advanced search capabilities, iv) whether or not the resources are annotated, and v) whether the index establishes a resources classification.
