"Open (Accessible)" refers to the idea that information, resources, and services should be available to everyone without barriers. This concept promotes inclusivity, ensuring that people of all abilities can access and benefit from various materials, whether they are digital or physical. Accessibility can include features like screen readers for the visually impaired or ramps for those with mobility challenges. In the context of technology, "open" often relates to software and data that can be freely used, modified, and shared. Examples include open-source software like Linux and open data initiatives that allow researchers and the public to utilize information for various purposes, fostering innovation and collaboration.
