It is a very notable file format used by many devices and lots of software can read it. The only reason its hard to reference is because the company that develops it basically just publishes a C file with how to use it and everyone uses that to write their own implementations.
Whether something is notable or not is subjective. Since many editors collaborate on Wikipedia, there's a common standard that editors use to judge whether a topic is notable.
The test is called the "general notability guideline". In short, any topic needs to have at least 2 citations to different sources that meet all of the following requirements:
1. The source provides significant coverage (at least 1-2 sizable paragraphs) of the topic
2. The source is reliable
3. The source is a secondary source that is editorially and financially independent of the subject (and of the other source)
So if the official documentation isn't enough and info on random websites isn't enough than what possible source can be used? Do we have to find a group of academics to look at the file and write a PDF saying "yep the official docs are indeed correct"?
You can absolutely cite the official documentation, and it's considered a reliable source for your article.
However, it isn't considered an independent source, since it was written by a company with a vested interest in the topic.
To prove that the file type is notable, you'll need at least different 2 sources that meet all 3 requirements: they must provide significant coverage of the topic, be reliable, and be independent of the topic.
You don't have to use these sources to write all of the content in your article, but they do have to be cited as references to pass the notability test.
The three most common kinds of reliable sources are:
- Articles or web pages from a reputable news organization, magazine, or web publisher (with an editorial team)
- Books from a reputable publishing company
- Publications from a peer-reviewed academic journal
Offline and non-English sources are accepted.
If you can't find at least 2 sources that meet these requirements, then the topic doesn't pass the notability test and isn't suitable for Wikipedia. In this case, you're probably better off sharing your article somewhere else, such as Wikibooks, Wikiversity, or your personal blog.
Provided those two different newspapers wrote on her life in detail, not just a mention, yes. See the following section of the notability guidelines:
"Significant coverage" addresses the topic directly and in detail, so that no original research is needed to extract the content. Significant coverage is more than a trivial mention, but it does not need to be the main topic of the source material.
Interesting... and along the same lines as the parent comment, if two independent blogs had written about the file format in detail, I wonder if that’s enough.
Most tech blogs have just one author, and their posts don't go through a high-quality editorial process. Wikipedia calls these blogs "self-published sources", and they usually aren't considered reliable sources.
