Introduction

DiTTo implements a many-to-one-to-many architecture, meaning that a distribution system is represented in a core structure whithin DiTTo and that parsers need to be developped to link this core representation to existing formats.

These parsers can be classified in:

• readers which read from an existing format such as OpenDSS and build the core representation with the input data
• writers which ouptut the core representation to a given existing format.

The main strength of this approach compared to classic one-to-one mappings lies in its modularity. When implementing a new reader for a given format, the capability to export to all supported formats comes for free.

Readers

Available

Here is a list of the available readers and their status:

Readers	Version assumed	Implementation stage
OpenDSS	todo	tested and stable
CYME	todo	tested and stable
GridlabD	todo	stable, needs more testing
Synergi	todo	untested
DEW	todo	untested, still under development
WindMill	Todo	Untested, still under development

There are two slightly different readers available: CSV and JSON which are not distribution system modeling formats but data representation formats. The readers can be used to load objects into DiTTo from basic CSV or JSON formats. They can be extremely useful for dumping a DiTTo model as is on disk and reload it later, or to apply specific modifications to existing DiTTo models (see more on TODO).

Writers

Available

Here is a list of the available writers and their status:

Writers	Version assumed	Implementation stage
OpenDSS	todo	tested and stable
CYME	todo	tested and stable
Ephasor	todo	Untested
GridlabD	todo	Untested, still under development

As for readers the JSON writer enables one to save a raw DiTTo model to disk.
