LegalRuleML Core Specification V1.0 OASIS Standard published
The specification for representing legal norms and rules is now an OASIS Standard.
OASIS is pleased to announce the publication of its newest OASIS Standard, approved by the members on 30 August 2021:
LegalRuleML Core Specification Version 1.0
30 August 2021
Legal texts, e.g. legislation, regulations, contracts, and case law, are the source of norms, guidelines, and rules that govern societies. As text, it is difficult to label, exchange, and process content except by hand. In our current web-enabled world, where innovative e-government and e-commerce are increasingly the norm, providing machine-processable forms of legal content is crucial.
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.
The project received 4 Statements of Use from Livio Robaldo, Swansea University, CSIRO Data61, and CirSFID-AlmaAI.
