An accessible file is a file whose content can be accessed with assistive technologies, such as a screen reader. A suitable structure for the file, such as the use of heading styles, the structure of tables and the text equivalents of images are part of accessibility. If you have used Word, LibreOffice or the like to write your work, as well as the heading styles, table and image tools in these programs, you can create an accessible pdf file.
The file to be saved to Osuva must be accessible.
If one picture is worth more than a thousand words, then the alt text is a summary of those thousand words. Alt text is not the same as caption.
The file format of the accessible pdf file is PDF/UA. In the thesis, however, the reliability of archiving is a priority, so the PDF/A file format is used when creating the thesis.
First, check the accessibility of the file in the word processing program.
Make your documents accessible to users with disabilities. The word processing program does not know which text you have intended as a title and which is plain text if no styles have been used, i.e. those errors are not reported by the checking tool.
From the File - Properties menu, check that the name is the same as the name of the thesis (no subtitle) and that the author is your own name.
The computers in the university's computer classes have PDF-XChange, which can be used to convert a finished PDF file into PDF/A format.
