The Tuple-Attribute language (TA)is based on the RSF triple notation. Edges and nodes are specified identically to RSF. Nodes and types can be attributed. Attributes can be nested (i.e., attributes can have sub-attributes). Attribute values are either a string or a list. The list items are either strings or sub-lists.

The following gives a code example that contains two nodes (called 'one' and 'two') that are connected with an edge. The edge is colored red.

  myEdge one two
  (myEdge one two) { color = red }
