009 | abstract | Topological complex without any specified geometric realisation | 2012-07-04 |

004 | fullPlanarGraph | 2-dimensional topological complex that is planar. (A 2-dimensional topological complex is commonly called full topology in a cartographic 2D environment.) | 2012-07-04 |

006 | fullSurfaceGraph | 2-dimensional topological complex that is isomorphic to a subset of a surface | 2012-07-04 |

008 | fullTopology3D | Complete coverage of a 3D Euclidean coordinate space | 2012-07-04 |

001 | geometryOnly | Geometry objects without any additional structure which describes topology | 2012-07-04 |

003 | planarGraph | 1-dimensional topological complex that is planar. (A planar graph is a graph that can be drawn in a plane in such a way that no two edges intersect except at a vertex.) | 2012-07-04 |

005 | surfaceGraph | 1-dimensional topological complex that is isomorphic to a subset of a surface. (A geometric complex is isomorphic to a topological complex if their elements are in a one-to-one, dimensional-and boundry-preserving correspondence to one another.) | 2012-07-04 |

002 | topology1D | 1-dimensional topological complex -- commonly called chain-node topology | 2012-07-04 |

007 | topology3D | 3-dimensional topological complex. (A topological complex is a collection of topological primitives that are closed under the boundary operations.) | 2012-07-04 |
