Language Specifications
A programming language is an artificial language that can be used to control the behavior of a machine, particularly a computer. Programming languages, like human languages, are defined through the use of syntactic and semantic rules, to determine structure and meaning respectively. From : en.wikipedia.org/wiki/Programming language Programming language - A standard which specifies how (sort of) human readable text is run on a computer. Programming languages vary quite a lot in style (e.g. Procedural - made up of blocks run from each other, Object-Oriented - program made of a set of communicating isolated objects, Functional - everything is a function!, ...), and make some things easier than others. There are low-level languages which give you lots of control over the computer and things run quickly, or higher level where you can get the computer to do lots with little work but have less total control, however these catagories aren't fixed. Examples include C, FORTRAN, Perl, Python, BASIC, Pascal, FORTH. From : http://www-xray.ast.cam.ac.uk/~jss/lecture/computing/notes/out/glossary/
XPL
The eXtensible Presentation Language (XPL) has been developed within national research projects with the intention to make easier the presentation of contents supplied by Web-based services in thematic networks ontologically described. eXtensible Presentation Language is a language based on a methodological approach that supports designers in addressing issues related to the user interfaces requirements both for the design and the development phases.
The language is made up by few essential patterns of visualization which constitute the structure of the document, referring to the XSLT libraries the graphical aspect for each channel. Anyway the language can be extended either with new patterns for the same channel and with new related XSLT templates. A methodology has been developed to extend the structure with others new patterns, re-using existing ones. The research results regarding the eXtensible Presentation Language, have been achieved thanks to the collaboration with the Universit degli Studi di Palermo. This joint effort has produced pubblications in order to determine verbal interaction patterns. The latter have been gathered in a collection aimed at enhancing the accessibility of contents.
