External Technical Documentation
Some technical documentation is generated automatically from the OTP source code and available from other locations. The Javadoc describes OTP's Java classes and their methods for software developers who call or change this code directly. The Web Service API documents describe the endpoints OTP exposes via its HTTP interface. It is generated automatically by Enunciate from comments in the source code, so may be incomplete or overly verbose in places. These documents are organized into folders for different release versions of OTP.
Send questions and comments to the user mailing list. Discuss internal development details on the dev mailing list. File bug reports via the Github issue tracker. Note that the issue tracker is not intended for support questions or discussions. Please post them to one of the mailing lists instead.
