Currently, Bobby only processes HTML and does not have the technology available to process other formats. Flash, Java, and other media and plugins are external formats that are placed into a web page with a simple HTML tag. When Bobby detects this tag, it asks generic questions but is not able to perform an evaluation. PDF files are sometimes accessible, but the access can be limited or unpredictable. However, the results of the conversion depend on how the original PDF document was authored and are not always satisfactory.
Accessibility is ultimately a human endeavor.
It is determined by whether or not a diverse group of people with a variety of abilities and disabilities can access information efficiently. Bobby can help users make web pages more accessible, but can not guarantee total accessibility. Authors are on the honor system. We encourage authors to periodically retest pages with Bobby to make sure that the Bobby Approved rating still applies whenever pages are modified. The HTML validator checks that the HTML code of a web page is well-structured according to the HTML specification.
