4. Electronic document manipulation languages
The aim of this section is to outline current trends in the implementation of electronic document manipulation languages. There are many prototypes and proposals for such languages, so rather than attempting to present them exhaustively, we have chosen to focus on certain representative proposals. The references given in brackets indicate the names of the authors and the dates of these proposals.
4.1 General overview
Current proposals, in which we find similar concerns about the query aspect, concern on the one hand languages for querying content, and on the other hand languages for querying structure. We will briefly present a few characteristics of languages that enable mixed queries on content and/or structure. In order to better define the typology of languages...
