We are pleased to announce that the OASIS LegalRuleML TC members have recently approved a Committee Specification Draft (CSD) and submitted it for a 15-day public review:
LegalRuleML Core Specification Version 1.0
Committee Specification Draft 02 / Public Review Draft 02
17 May 2017
What is LegalRuleML and why is it important?
Legal texts, e.g. legislation, regulations, contracts, and case law, are the source of norms, guidelines, and rules. As text, it is difficult to exchange specific information content contained in the texts between parties, to search for and extract structured the content from the texts, or to automatically process it further. Legislators, legal practitioners, and business managers are, therefore, impeded from comparing, contrasting, integrating, and reusing the contents of the texts, since any such activities are manual. In the current web-enabled context, where innovative eGovernment and eCommerce applications are increasingly deployed, it has become essential to provide machine-readable forms (generally in XML) of the contents of the text.
The objective of the LegalRuleML Core Specification Version 1.0 is to define a standard (expressed with XML-schema and Relax NG and on the basis of Consumer RuleML 1.02) that is able to represent the particularities of the legal normative rules with a rich, articulated, and meaningful mark-up language.
- defeasibility of rules and defeasible logic;
- deontic operators (e.g., obligations, permissions, prohibitions, rights);
- semantic management of negation;
- temporal management of rules and temporality in rules;
- classification of norms (i.e., constitutive, prescriptive);
- jurisdiction of norms;
- isomorphism between rules and natural language normative provisions;
- identification of parts of the norms (e.g. bearer, conditions);
- authorial tracking of rules.
About the TC:
The OASIS LegalRuleML TC defines a rule interchange language for the legal domain. The work enables modeling and reasoning that allows implementers to structure, evaluate, and compare legal arguments constructed using the rule representation tools provided.
Membership in the OASIS LegalRuleML TC is open to all interested persons.
Public Review Period:
The public review starts 15 September 2017 at 00:00 UTC and ends 02 October 2017 at 23:59 UTC.
