Abstract: “Data economy drives us into a world in which reusing data has an important economical impact. However, data consumer has no enough mechanisms for developing apps that reuse data. A developer is willing to know which is the impact of the data to decide which is consumed within the envisioned smartphone application. One of the best ways of measuring impact comes from the research arena, in which metrics based on citations are provided (such as bibliometrics and altmetrics) to measure the impact of authors, articles and journals. Accordingly, to measure how open data is reused it must be cited. However, data citation is not a common practice and it is quite difficult to obtain metrics of reused data and apps. This paper describes first step of an approach to (i) extract information about used data in app catalogs with scraping and other techniques to compose a metadata database, (ii) compute some metrics to measure the impact of open data sets, and (iii) visualize results to help data con”
