This is TriplePlace a light weight and flexible Triple Store for Android. It uses a indexing structure similar to the one in Hexastore. TriplePlace uses TokyoCabinet as persistent storage system. I've also published a patched version of TokyoCabinet and TokyoCabinet-Java-API resp. TokyoCabinet-Android-API.
