Methods
In order to collect, share, or exchange tagging data, or create a bridge among heterogeneous social tagging sites, methods should implement by types of mashups. In general, most social media sites offer open APIs to expose their data and we can gather the data using them. It, however, is hard to integrate and interoperate data through diverse applications on syntactic and structural means; we need semantic techniques such as SA-REST (Semantically Interoperable and Easier-to-Use Services and Mashups)
The OpenTagging Platform is an open framework that is scalable and interoperable with all existing tagging data from heterogeneous sources or applications.
