OpenLink has worked with the Twitter API since it became available. Among other things, we’ve created:
-
An Ontology/Vocabulary comprising terms for describing Tweets
-
A Virtuoso Sponger Cartridge (analogous to a Connector or Driver) for generating Linked Data “on the fly” from Tweets and Threads
Here are some live examples:

- OpenLink Tweet Unroller — Codenamed “Outarde”, this powerful productivity tool leverages the power of RDF deployed using Linked Data principles. Outarde adds new dimensions to the creation, publication, access, and recall of Knowledge Graphs. For instance, it simplifies the transformation of Twitter Threads into Knowledge Graph nuggets for future reuse and recall using Text Search or declarative query languages such as SQL or SPARQL.
