Openness:
Why?
Open content provides means of access to resources from others all within the Web, allowing people to manipulate, change, and control the dynamic of the platform. New and innovative ideas are created through open technologies that give room for collaborative interception from a diverse range of people. This makes information on the web widely spread and is the reason there is so much of it.
How?
The web can be restricted based on the search engine you’re using, but mostly it is open to the public to post, exchange, and delete information. Wikipedia, for example, is a creative common space to collect a large range of data and knowledge from people to have a full review of something or a concept. Open work can be distributed and changed like creating a website or posting a youtube video.
Accessibility:
Why?
An accessible design for content allows for diverse persons to relay information to and from the web. Accessibility should be easy, affordable, and universal so that all can use it if they have an impairment or not. When accessibility is implemented it not only makes retrieval easier for those who may need it but it makes things more clear, concise, and generally usable.
How?
To make content accessible one can rely on a lot of content already out there – most videos now have closed captions or translations, and most online newspapers have links embedded in the text for further contextual information. Princeton gives a checklist on creating digital accessibility which provides more examples of how structure, visuals, and context can determine the availability content is to all people.
