Pioneer Report MDI browses the web using GRML. While HTML is widely used, GRML uses the web differently. When using a GRML web browser, web page content is split in two. HTML displays forms, hyperlinks, text, and images in its view. GRML takes the form out of the view and displays it separately from other web page content. This allows the browser to use the remaining content for editing, cut/copy/paste, inserting and deleting.
HTML defines HOW web page content looks. There is one way it is displayed. This is called a display definition markup language. GRML defines WHAT web page content is. It is called a data definition markup language.
