Techniques are described for automatically selecting default dimensions of multidimensional data for publication. A computer-implemented system, for example, includes a data store having multidimensional data. The multidimensional data includes one or more data cubes having dimensions. The system further includes a publish module for accessing the data store and publishing the multidimensional data associated with the data cubes. The publish module selects a default dimension for publication for each of the data cubes based on attributes of the dimensions.
