Released 2010

Strabon's own publications page lists its earliest paper (naming Strabon explicitly) as a November 2010 SSN workshop paper at ISWC 2010; a second stRDF/stSPARQL paper from ESWC 2010 (May-June 2010) is listed in the same 2010 section. Used as the earliest documented year Strabon existed, since no separate software release date is published.

  • In Proceedings of 3rd International workshop on Semantic Sensor Networks 2010, in conjunction with ISWC 2010, November 2010, Shanghai, China.
