CALL FOR PARTICIPATION

OASIS LegalRuleML Technical Committee

The charter for this TC is as follows.

=== Charter ===

1.a Name of the TC:

LegalRuleML Technical Committee

1.b Statement of Purpose:

The goal of the LegalRuleML TC is to extend RuleML [RuleML 2011] with
features specific to the formalisation of norms, guidelines, and legal
reasoning.

Legal texts are the source of norms, guidelines, and rules that often
feed into different concrete (usually XML-based) Web applications.
Legislative documents
typically provide general norms and specific procedural rules for
eGovernment and eCommerce environments, while contracts specify the
conditions of services and business rules (e.g. service level
agreements for cloud computing), and judgments provide information
about arguments and interpretation of norms that establish concrete
case-law.

The ability to have proper and expressive conceptual models of the
various and multifaceted aspects of norms, guidelines, and general
legal knowledge is a key factor for the development and deployment of
successful applications.

The LegalRuleML TC aims to produce a rule interchange language for the
legal domain. This will enable modeling and reasoning such that
implementers can
structure, evaluate, and compare legal arguments constructed using the
rule representation tools provided.

1.c Scope of Work:

The Artificial Intelligence (AI) and Law communities have converged in
the last twenty years on modeling legal norms and guidelines using
logic and other formal techniques [Ashley 2011]. Existing methods
begin with the analysis of a legal text by a Legal Knowledge Engineer
who extracts the norms and guidelines, applies models and a theory
within a logical framework, and finally represents the norms using a
particular formalism. In the last decade, several Legal XML standards
were proposed to describe legal texts [Lupo et al. 2007] with
XML-based rules (RuleML, SWRL, RIF, LKIF, etc.) [Gordon et al. 2009;
Gordon 2008]. In the meantime, the Semantic Web, in particular Legal
Ontology research combined with semantic norm extraction based on
Natural Language Processing (NLP) [Francesconi et al. 2010], gave a
great impulse to the modelling of legal concepts [Boer et al. 2008;
Benjamins 2005; Breuker 2006].

Based on this, the work of the LegalRuleML Technical Committee will
focus on three specific needs:

1. Closing the gap between natural language text description and
semantic norm modelling, in order to realise an integrated and
self-contained representation of legal resources that can be made
available on the Web as XML representations [Palmirani 2009]. This
formal underpinning can then foster Semantic Web technologies such as:
NLP, Information Retrieval (IR), graph representation, as well as Web
ontologies and rules.

2. To provide an expressive XML standard for modelling normative rules
that is able to satisfy the legal domain requirements. This will
enable use of a legal reasoning level on top of the ontological layer
that aligns with the W3C envisioned Semantic Web stack. This approach
seeks also to fill the gap between regulative norms, guidelines and
business rules in order to capture and model the processes embedded in
those guidelines and make them usable for the workflow and business
layer [Governatori 2010; Rotolo 2009; Grosof 2004];

3. Supporting the Linked Open Data [Berners-Lee 2010] approach to
modeling regarding not only the semantics of raw data (acts,
contracts, court files,
judgments, etc.), but also of rules in conjunction with their
functionality and usage. Without rules or axioms, legal concepts
constitute just a taxonomy
[Sartor 2009].

The LegalRuleML TC work will address these three main goals and
provide means for modeling norms, guidelines, judgements, and
contracts using a semantic approach.

In particular, the LegalRuleML work will extend the existing RuleML,
RIF and related Web rule work by improved modeling as well as
representing and capturing the legal knowledge embedded in legal
texts.

Specifically, the LegalRuleML work will facilitate the following
functionalities.

A) Support for Modeling different types of rules:

- CONSTITUTIVE RULES, which define concepts or constitute activities
that cannot exist without such rules (especially Legal definitions
such as "property").

- TECHNICAL RULES, which state that something has to be done in order
for something else to be attained (especially Rules governing
taxation).

- PRESCRIPTIVE RULES, which regulate actions by making them
obligatory, permitted, or prohibited (especially obligations in
contracts).

B) Implementing ISOMORPHISM [Bench-Capon-Coenen 1992]. To ease
validation and maintenance, there should be a one-to-one
correspondence between the rules in the formal model and the units of
(controlled) natural language text that express the rules in the
original legal sources, such as sections of legislation.

C) Manage the REIFICATION [Gordon 1995] of rules that are objects with
properties, such as Jurisdiction, Authority, Temporal attributes
[Palmirani 2010; Governatori 2009; Governatori 2005]. These elements
have to be added to the current RuleML to enable effective legal
reasoning.

D) Represent NORMATIVE EFFECTS and VALUES. There are many normative
effects that follow from applying rules, such as obligations,
permissions, prohibitions, and also more articulated effects such as
those introduced. Usually, some values are promoted by legal rules as
well.

F) Implement DEFEASIBILITY [Gordon 1995, Prakken 1996, Sartor 2005].
When the antecedent of a rule is satisfied by the facts of a case (or
via other rules),
the conclusion of the rule presumably holds, but is not necessarily
true. The defeasibility of legal rules breaks down into the following
issues: Conflicts and Exclusionary rules.

Lastly, the LegalRuleML work will also aim to model legal procedural
rules. Rules not only regulate the procedures for resolving legal
conflicts, but also are used for arguing or reasoning about whether or
not some action or state complies with other, substantive rules. In
particular, rules are required for procedures which regulate methods
for detecting violations of the law, i.e., which determine the
normative effects triggered by norm violations, such as reparative
obligations, which are meant to repair or compensate violations. Note
that these constructions can give rise to very complex rule
dependencies, because the violation of a single rule can activate
other (reparative) rules, which in turn, in case of their violation,
refer to other rules, and so forth.

In this case, the Deliberation RuleML and Reaction RuleML parts [Boley
et al. 2010] are coordinated within the LegalRuleML module to produce
benefits for applications and reasoning engines (avoiding redundancy
in the rules as well as facilitating coordination, synchronisation,
and cooperation.)

Compatibility:

Compatibility with the RuleML 1.0 schemas [Athan et al. 2011; Boley
2011; Boley et al. 2010; Wagner et al. 2004; Boley et al. 2001] and
interoperability with the main languages for rule modeling, mainly
Common Logic, RIF, and SWRL.

Out of Scope:

Developing tools for LegalRuleML. (This will be started by the
supporters of this proposal and others independently once a first
stable version of LegalRuleML exists.)

1.d Deliverables

The LegalRuleML TC will provide XML representations that address the
aforementioned requirements and support interchange with the business
rule domain.

The following deliverables are expected:

D1. LegalRuleML semantic level (e.g. temporal dimension) drafts -
within six months of the first TC meeting

D2. LegalRuleML logic level (e.g. defeasibility, deontic, and
argumentation) drafts - within eight months of the first TC meeting

D3. LegalRuleML integration with business and process rule drafts -
within ten months of the first TC meeting

D4. Pilot use cases - within twelve months of the first TC meeting

D5. Tutorials and general documentation - continuously produced and
updated during the entire process

The semantic and logic levels constitute the core part of the
LegalRuleML functionality. They define the principles of design, the
architecture of the syntax, the main elements for managing patterns,
abstract types, groups of attributes, general classes, ontology-level
connections, and rule-level connections.

Maintenance:

Once the TC has completed work on a deliverable that has become an
OASIS Standard, the TC will enter "maintenance mode" for the
deliverable.

The purpose of maintenance mode is to provide minor revisions to
previously adopted deliverables to clarify ambiguities,
inconsistencies, and obvious errors. Maintenance mode is not intended
to enhance a deliverable or to extend its functionality.

The TC will collect issues raised against the deliverables and
periodically process those issues. Issues that request or require new
or enhanced functionality shall be marked as enhancement requests and
set aside. Issues that result in the clarification or correction of
the deliverables shall be processed. The TC shall maintain a list of
these adopted clarifications and shall periodically create a new minor
revision of the deliverables including these updates. Periodically,
but at least once a year, the TC shall produce and vote upon a new
minor revision of the deliverables.

1.e IPR Model

This TC will operate under the "RF (Royalty Free) on Limited Terms"
IPR mode as defined in the OASIS Intellectual Property Rights (IPR)
Policy.

1.f Anticipated Audience

The anticipated audience for this work includes:

1. Vendors and service providers offering products and/or services in
the legal domain (e.g. eGovernment, cloud computing SLAs, contracting,
and legislation)

2. Authors of other specifications that require rule language
standards for legal, regulatory and policy representations

3. Software architects who design, write, integrate, and deploy rule
engines in the legal domain

4. End users modeling legal rules that require an interoperable
solution using a standard language

5. The U.S. NIEM community for government domain rule management and
representation

6. The OASIS LegalXML MS and other OASIS entities that are providing
input for and/or are planning to refer to LegalRuleML from their
specifications.

1.g Language:

The output documents will be written in (US) English. TC meetings
shall be conducted in English.
