Project partners Academic input: Leibniz Center for

Law (University of Amsterdam) and Technical University Delft

Technology input and product development: BeInformed and O&I

User input and validating pilot studies: Immigration & Naturalization Service (IND) and Dutch Tax and Customs Administration (Belastingdienst)

About the project Agile: Advanced Governance of

Information services through Legal Engineering

Goal: Increase the agility of organizations that deliver law-governed services in a network environment

Products: 1. two PhD theses (Saskia & Yiwei)2. design methodology & prototype specification

language3. prototype distributed service-oriented

architecture & supporting tools

Page 4: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Two PhD theses Leibniz Center: accounting for how law

is implemented in the organization (Saskia van der Ven)

Delft University: accounting for how rational agents use the law, and the way it is implemented (Yiwei Gong) Effectiveness and efficiency Evasive behaviour of clients (taxpayers,

immigrants) Intentions of other network partners

(employers, family members, etc.)

Domains for examples and pilots Sales transactions (private law) Legislating (reusability) Knowledge worker permits (IND)

Involves income criterium, potential for interaction with client, Belastingdienst and employer in application process

Income and wages (Belastingdienst) One person business (ZZP) wages tax

Agility and Traceability

Page 7: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Two aspects of agility Quick adaptation of the organization

Processes, services, knowledge resources are robustly designed

Decoupling: Separation of concerns in specification and implementation

Quick impact analysis Which processes, services, knowledge

resources, etc are affected by a change?

Page 8: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Legal impact analysis Is a service, process, or resource redesign

legally speaking effective and is it compliant? Sources of law: legislation, case law,

organizational guidelines What problems and opportunities are

created by a change in the sources of law for existing services, processes, and resources? Compliance, efficiency, enforceability, changing

patterns of service delivery (chain partners) and consumption (taxpayers, immigrants)

Page 9: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Abilities to develop in Agile1. monitoring and managing the sources of law relevant to the

organization, distinguishing versions of these sources of law, and determining the applicability of rules originating from these sources of law in time and to categories of cases;

2. maintaining traceability from sources of law to implementation knowledge resources without ending up with Gordian provenance link knots;

3. efficiently and quickly justifying existing business processes, data in databases, etc, justified by old law, in new law if possible;

4. anticipating the effects of changes in law not directly addressing the organization itself to service delivery and consumption by network partners and clients;

5. developing an organizational structure, IT infrastructure, other resources, and – importantly - network arrangements that are robust in the face of changes to the law; and

6. delivering timely, constructive, and accurate feedback to the legislator.

Traceability and Impact Analysis I The main knowledge resource of legal

impact analysis: Provenance links from implementation knowledge resources to sources of law Provenance = origin, history Tends to either be very incomplete or to

degenerate into a Gordian knot Domain-specific obligations are more likely

to be explicitly linked than ability-creating rules, even though the latter are more likely to cause big changes if they are changed!

2.1 uitzondering VVR BEP, aantoonbaar geen document kunnen krijgenDe vreemdeling kan worden vrijgesteld van de voorwaarde dat hij/zij een geldig GD moet hebben om een VVR BEP te kunnen krijgen.

Dit geldt als de SvJ oordeelt dat er:- valide pogingen zijn gedaan om een geldig GD te krijgen, en;- is aangetoond dat de vreemdeling geen geldig GD van de regering van het land waarvan hij onderdaan is, kan krijgen.

Dit laatste geldt in ieder geval voor Somaliërs.

Traceability and Impact Analysis II Decoupling approach: simple inert

concept-centered requirements model intermediating between sources of law and implementation resources New staff uses it to acquire domain knowledge However, it plays no role in impact analysis

and implementation Determination of applicability of rules is hard

Approach: rule applicability reasoning & services simulation using an improved requirements model

Page 14: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Approach on the conceptual level Improving agility of organizations by

1. Ontological stratification and supervenience: rigid identity criteria distinguish the legal institutional domain from its implementation in the organization

2. Versioning (and identification) of sources of law (MetaLex) and of implementation resources

3. Create a mediating Agile knowledge resource that distinguishes three knowledge domains

4. Traceability based on rules bridging knowledge domains and on concepts describing the knowledge domains

Page 15: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Three knowledge domains supervenient on eachother

Legal theory input (Re)presentation: Some medium

(re)presents a proposition or rule Constitutiveness: Some (brute) thing

counts as a legal thing according to some rule Normativity: action counts as a violation Abstraction: Every legal thing must be

constituted by some thing to exist Applicability: Some rule applies to a thing Evidence: something is evidence for a

proposition

Interface to other knowledge resources Specifications, logical models, knowledge base

rules, schemas, etc, used in the organization are not in the bottom layer, but share (contextualized interpretations of) concepts, rules, individuals, etc with the bottom layer.1. To share is to use the same IRIs for reference, or to

be able to resolve the IRI in one model to the corresponding one in the other.

2. Agile resources minimally interfere with technology choices in the organization

3. Import/export functionality is however very desirable, in particular for knowledge bases

4. In usage, knowledge is contextualized to problem setting (assumptions etc.) and restricted to tool/language-specific expressive fragment and semantics (datalog, epistemic interpretation, negation as failure)

Page 23: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

“Brute reality” business processes: when, why, and how

to react when citizens want to interact with the organization?

citizen life event modeling: when and why do citizens want/have to interact with the organization?

services: Description of transaction script from perspective of client role focusing on the changes (on the service target) valuable to the client, as advertized by a provider capable of bringing about those changes

Page 24: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Service and business process patterns legal services: the service target is the

legal position of the client: the value provided is an improvement of the client's position, and intended by the client

Legal position analysis of transaction scripts based on Hohfeldian relations: bundles of duties/rights and powers/liabilities Service notion adds provider/client roles

Reuse business ontologies?

Example rulesDemonstration of how rules define the interface between domains and exist within domains

Page 26: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Example Rules:

t1 The publication of a text presenting a rule counts as the creation of that rule.

t2 Rule t1 applies to text published by a rule maker.

t1 represents legal rule r1 and t2 represents legal rule r2

logical rules a1 and a2 (in OWL2) represent their meaning to agents that have to apply them

Page 27: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Rules in Agile Legal rules are distinguished from

(presenting) text and from (representing) logical axioms Exist in institutional reality, Exist in time, and Are Traceable

to expressions of sources of law (MetaLex) representation and applicability

to their use in implementation resources contextualization of the meaning of rules

Logical rules are about three layers of reality and the interfaces between them

Page 28: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

ExampleOWL2 rule a1: “The publication of a

text presenting a rule counts as the creation of that rule.”

if Publication that(resultsIn some (Text that (represents some Rule)))

then(constitutes some Creation that(resultsIn some Rule) and (applicable value r1)))

Page 29: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Other exampleOWL2 rule a2: Rule t1 applies to text

published by a rule maker.if Rule that (representedBy some

(metalex:Expression that(metalex:realizes value t1)))

then(appliesTo all (Creation that

(actor some RuleMaker) and (applicable value r2)))

Page 30: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

FRBR bibliographic layers in CEN MetaLex

Page 31: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Applicability rules If t1 changes (a new expression of the

work) A new legal rule presented by the new

expression is created And rule r2 automatically applies to it

because it applies to all rules presented in expressions of t1

Page 32: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

Applicability and defeasibility Two kinds of applicability

Actual: if the rule produces a legal effect it is/was applicable

Potential: If it will produce a legal effect if applied it is applicable

Defeasibility and whole OWL2 axioms no special conditional but belief base revision presents a challenge in accounting for its

semantics Purpose is to find problems rather than solve

them

Page 33: Alexander Boer aboer@uva.nl Tom van Engers Saskia van de Ven

To do in the next years Versioning methodology for all resources

MetaLex for sources of law Making the modeling simple using patterns

“Model sentences” in the law Reusable service, transaction, process,

information carriers patterns (and agents) Easy to use model editor Develop agent simulation architecture for

Impact analysis Simulating alternative implementations
