MetaLex

Status MetaLex and LKIF

October 16th, 2007

The linked paper gives an update on and overview of two XML standard proposals dealing with two complementary aspects of electronic legislation – the documents themselves as a carrier, and an institutional reality they represent – in a coherent way: MetaLex XML and the Legal Knowledge Interchange format (LKIF). MetaLex XML is well on its way to becoming formal and de facto standard for legislation in XML. LKIF is yet to be submitted as a proposed standard. LKIF includes some interesting innovations from an AI & Law perspective.

Note that this paper is about the MetaLex CEN prenorm, and not about MetaLex 1.3, its predecessor. A general remark about this confusion: MetaLex 1.3.* is still used by some important users, while MetaLex CEN is still premature. As soon as we have a more complete CEN agreement, and - very importantly - have reimplemented basic support functionality like the XSL-FO stylesheets for the CEN standard, this website will be reorganized. The MetaLex 1.3 schema will no longer be changed, except maybe for minor bug patching. Some tools that use MetaLex 1.3 are however still under development.
