The users of these systems freely associate tags to system's resources -- e.g., URLs, images, bookmarks. The term folksonomy refers to this collective classification, which emerges from tagging carried by users interacting in web social environments. \par We proposed a hybrid entity to fuse ontologies and folksonomies, we call ``folksonomized ontology'', which combines complementary aspects of both. The formal and engineered knowledge of ontologies is fused with the latent semantics of social data. \par In this technical report we show the implementation of a crawler to collect data from folksonomic systems on the web. We discuss the API of this systems and the way the data was stored. } }
