The Accessible Publishing Knowledge Base covers a wide range of topics related to the production of accessible digital publications. In less technical terms, there are a lot of pages of information on this site.
To help ease locating information, these are two primary means of locating information:
- Manually searching the topic index for the site.
- Using the site search feature for a deeper scan of the content.
The best place to start looking for information is in the topic index as the topics are grouped into categories based on shared themes to make it easier to locate information.
The following list provides a brief explanation of each of the major topical categories:
- Accessibility Conformance
The accessibility conformance topics provide information on meeting the various accessibility standards that apply to digital publications, such as the EPUB Accessibility specification and the Web Content Accessibility Guidelines (WCAG).
The EPUB topics cover issues that are unique to the EPUB format. Accessibility requirements of the EPUB package document will be found in this section, for example.
The navigation topics describe how to author accessible navigation aids such as the table of contents and page list.
The metadata topics describe the accessibility properties available in widely used metadata standards such as schema.org and ONIX.
The HTML topics cover a broad range of issues related to producing accessible HTML content. Guidelines include how to use elements and attributes accessibly, how to create common publishing structures such as indexes and glossaries accessibly, and how to apply ARIA roles, states, and properties.
The CSS topics cover the accessible styling of content. These include issues with color perception, contrast, text resizing and spacing, and the reflowability of content.
- Scripted Content and Forms
The scripting and forms topics cover a range of issues related to adding interactive content to digital publications. Ensuring users can understand and control this type of content is key to this area.
- Fixed Layouts
The fixed layouts topics delve into issues with creating content that is laid out on pages with fixed dimensions (i.e., the content does not reflow to fit the screen but stays where it is positioned). This type of content rarely meets accessibility standards, but there are measures that publishers can take to help improve its readability.
- Synchronized Multimedia
The synchronized multimedia topics cover the creation of digital publications that provide synchronized text and audio playback, such as the EPUB 3 media overlays feature. These types of publications are often referred to as "read aloud" books.
- Text to Speech
The text-to-speech topics cover technologies that aid in producing high-quality TTS playback.
As the search engine is keyword based, it may return a lot of unrelated topics depending on what you are looking for.
