This work is licensed under a Creative Commons Attribution 4.0 International License. + + +Introduction +============ +This guide describes how to create documentation for the Open Network +Automation Platform (ONAP). ONAP projects create a variety of +content depending on the nature of the project. For example projects delivering +a platform component may have different types of content than +a project that creates libraries for a software development kit. +The content from each project may be used together as a reference for that project +and/or be used in documents are tailored to a specific user audience and +task they are performing. + +Much of the content in this document is derived from similar +documentation processes used in other Linux Foundation +Projects including OPNFV and Open Daylight. + + +End to End View +--------------- +ONAP documentation is stored in git repositories, changes are managed +with gerrit reviews, and published documents generated when there is a +change in any source used to build the documentation. + +Authors create source for documents in reStructured Text (RST) that is +rendered to HTML and PDF and published on Readthedocs.io. +The developer Wiki or other web sites can reference these rendered +documents directly allowing projects to easily maintain current release +documentation. + +Why reStructuredText/Sphinx? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +In the past, standard documentation methods included ad-hoc Word documents, PDFs, +poorly organized Wikis, and other, often closed, tools like Adobe FrameMaker. +The rise of DevOps, Agile, and Continuous Integration, however, created a paradigm +shift for those who care about documentation because: + +1. Documentation must be tightly coupled with code/product releases. In many cases, +particularly with open-source products, many different versions of the same code +can be installed in various production environments. DevOps personnel must have +access to the correct version of documentation. + +2. Resources are often tight, volunteers scarce. With a large software base +like ONAP, a small team of technical writers, even if they are also developers, +cannot keep up with a constantly changing, large code base. Therefore, those closest +to the code should document it as best they can, and let professional writers edit for +style, grammar, and consistency. + +Plain-text formatting syntaxes, such as reStructuredText, Markdown, and Textile, +are a good choice for documentation because: + +a. They are editor agnostic +b. The source is nearly as easy to read as the rendered text +c. Documentation can be treated exactly as source code is (e.g. versioned, + diff'ed, associated with commit messages that can be included in rendered docs) +d. Shallow learning curve + +The documentation team chose reStructuredText largely because of Sphinx, a Python-based +documentation build system, which uses reStructuredText natively. In a code base +as large as ONAP's, cross-referencing between component documentation was deemed +critical. Sphinx and reStructuredText have built-in functionality that makes +collating and cross-referencing component documentation easier. + +Which docs should go where? +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Frequently, developers ask where documentation should be created. Should they always use +reStructuredText/Sphinx? Not necessarily. Is the wiki appropriate for anything at all? Yes. + +It's really up to the development team. Here is a simple rule: + +The more tightly coupled the documentation is to a particular version of the code, +the more likely it is that it should be stored with the code in reStructuredText. + +Two examples on opposite ends of the spectrum: + +Example 1: API documentation is often stored literally as code in the form of formatted +comment sections. This would be an ideal choice for reStructuredText stored in a doc repo. + +Example 2: A high-level document that describes in general how a particular component interacts +with other ONAP components with charts. The wiki would be a better choice for this. + +The doc team encourages component teams to store as much documentation as reStructuredText +as possible because: + +1. The doc team can more easily edit component documentation for grammar, spelling, clarity, and consistency. +2. A consistent formatting syntax across components will allow the doc team more flexibility in producing different kinds of output. +3. The doc team can easily re-organize the documentation. +4. Wiki articles tend to grow stale over time as the people who write them change positions or projects. + +Structure +--------- +A top level master document structure is used to organize all +documents for an ONAP release and this resides in the gerrit doc repository. +Complete documents or guides may reside here and reference parts of +source for documentation from other project repositories +A starting structure is shown below and may change as content is +integrated for each release. Other ONAP projects will provide +content that is referenced from this structure. + +.. index:: master + + +:: + + docs/ + ├── releases + │ ├── major releases + │ ├── projects + │ ├── cryptographic signatures + │ └── references + ├── onap-developer + │ ├── architecture + │ ├── tutorials + │ ├── setting up + │ ├── developing + │ └── documenting + └── onap-users + ├── vf provider + ├── service designer + ├── service administrator + └── platform administrator + + + +Source Files +------------ +All documentation for a project should be structured and stored +in or below `<your_project_repo>/docs/` directory as Restructured Text. +ONAP jenkins jobs that verify and merge documentation are triggered by +RST file changes in the top level docs directory and below. + + +.. index:: licensing + +Licensing +--------- +All contributions to the ONAP project are done in accordance with the +ONAP licensing requirements.
