A trend in F/OSS studies is the use of metadata stored in a repository of repositories or RoRs. This paper utilizes data obtained from such RoRs -FLOSSmole- to study the types of projects being developed by the F/OSS community. We downloaded projects by topics data in five areas (Database, Internet, Software Development, Communications, and Games/Entertainment) from Flossmole{\textquoteright}s raw and summary data of the sourceforge repository. Time series analysis show the numbers of projects in the five topics are growing linearly. Further analysis supports our hypothesis that F/OSS development is moving {\textquotedblleft}up the stack{\textquotedblright} from developer tools and infrastructure support to end-user applications such as Databases. The findings have implications for the interpretation of the F/OSS landscape, the utilization and adoption of open source databases, and problems researchers might face in obtaining and using data from RoRs. }, issn = {978-0-387-72485-0}, doi = {http://dx.doi.org/10.1007/978-0-387-72486-7_12}, attachments = {https://flosshub.org/sites/flosshub.org/files/Using\%20Repository\%20of\%20Repositories.pdf}, author = {Sowe, Sulayman and Lefteris Angelis and Stamelos, I. and Y.
