The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

This paper argues that proactive life event services require revising the accepted ontology of public services. The accepted definition in [8] treats a public service as an offering activity plus activities that process a request to use the service; proactive life event services are different because the citizen may never ask for the service. The paper therefore replaces request processing with service initialization processing: a life event—an event separating two states of affairs of a person or organization—triggers zero or more service initialization activities, governed by admission rules. Getting these meanings right matters because e-government architecture and interoperability depend on shared definitions of the underlying terms.

What carries the argument

The load-bearing machinery is the ontological metamodel built on the distinction between universals and particulars, endurants and perdurants, and states and events, with the life event as an event separating two states of affairs of an agent. Within that metamodel, the decisive move is replacing the concept of service request processing with service initialization processing: a life event, reflected by data events in registers, triggers zero or more service initialization processing activities, and admission rules expressed as reaction rules govern each trigger. This gives a vocabulary for representing 'assumed will' without an explicit request.

What would settle it

One concrete check would be to find an operating proactive public service whose initiation depends on a standing eligibility condition rather than on a discrete life-event data change; if such a service cannot be redescribed as a life event triggering service initialization, the paper's central replacement is not necessary.

Watch

Extended reading notes

Core claim

The central discovery, on the paper's own terms, is that the definition of public service must be changed to accommodate proactive life event services. Where [8] defined a public service as one service-offering activity plus request-processing activities, the proposed metamodel defines the service around service initialization processing triggered by life events. A life event is an event that separates the state of affairs of a physical or institutional agent before and after the event, and it can be reflected by data events in state registers, information systems, and databases. Those data events trigger zero or more service initialization processing activities, each including management and delivery; admission rules, expressed as reaction rules, decide whether the service is triggered, for instance by checking whether the person has opted out of proactive electronic delivery. The paper also contrasts its life-event notion with the narrower CPSV-AP Life Event, which only covers events relevant to public services.

Load-bearing premise

The load-bearing premise is that the Estonian regulation's 'assumed will' can be operationalized as event-triggered service initialization, and that proactive services cannot be captured by a broader notion of request; if an implicit or standing request were enough, replacing request processing would be unnecessary.

Editorial extensions

If this is right

If the paper is right, a citizen who never asks for a service can still receive it, because the life event itself triggers service initialization processing.
One life event can spawn zero, one, or many service initialization activities, so a single event such as a child's birth can consolidate several public services into one flow.
Admission rules become reaction rules; an opt-out from proactive electronic delivery is enough to block a trigger until an explicit request appears.
Agreement on the metamodel becomes a prerequisite for building interoperable e-government architectures, including aligning EU-level service catalogues.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

The author leaves implicit that the same event-triggered mechanism could handle painful life events such as unemployment or bereavement; those cases would stress the consent and opt-out machinery more than positive events do.
A testable extension is to compare this event-triggered model against a standing-authorization model on the same services; if behavior is identical, the paper's central replacement would lose its necessity.
Because the trigger is a data event in an official register, proactive services inherit the accuracy and timeliness of that register; a life event that is not registered cannot trigger anything.

Desk Editor's Note

read the letter

Read it. Short conceptual paper extending Guarino's service ontology to proactive life event services. The key move is replacing 'service request processing' with 'service initialization processing' triggered by life events. The paper is honest, clearly written, and grounded in the right literature. The metamodel in Fig. 1 is a reasonable first attempt to give e-government architects a shared vocabulary for proactive services.

The soft spot is exactly where the stress-test lands. Section 3 says it is 'necessary' to change the [8] definition because a proactive service may lack a direct desire to use it. But [8]'s definition is about requests, not desires. Nothing in that definition rules out an implicit or standing request, authorized by the citizen's assumed will and checked against opt-out and admission rules at the data event. So the replacement of request processing with initialization processing is a modeling choice, not a logical consequence. The paper gives no argument against the broader 'request' reading. That weakens the central claim from necessity to one plausible modeling option.

The paper also leaves 'service initialization processing' under-defined compared to the notion it replaces. The real content—admission rules, opt-out conditions—could equally be conditions on a generalized request. And the comparison with CPSV-AP is one paragraph; a systematic comparison would strengthen the interoperability argument.

On the positive side, the paper does introduce a new concept and connects it to reaction rules and deontic assignments from the author's own prior work, but self-citations are supportive, not load-bearing. The paper makes no empirical claims, so there is no data to scrutinize. The reasoning is internally consistent, and the author is clear about what is being proposed versus what is established.

Who is this for? Practitioners and researchers working on e-government ontologies, proactive services, and public service interoperability. It deserves a serious referee, but it needs revision before acceptance: the necessity claim must be either argued against the 'standing request' reading or softened to a design choice. I'd send it to review because the idea is worth engaging with, not because it's fully convincing.

Recommendation: accept for peer review with expectations of major revision.

Referee Report

4 major / 5 minor

Summary. The paper proposes an ontological analysis of proactive life event services in e-government, building on foundational ontology work by Guarino, Guizzardi, Nardi, Wagner, and others. It introduces a metamodel centered on endurants/perdurants, states/events, roles/phases, and social relators, and applies it to the notion of a life event. The central claim is that including proactive and life event services requires changing the definition of public service in [8]: because a proactive service may lack a direct desire to use the service, the paper replaces [8]'s concept of service request processing with a new concept of service initialization processing, triggered by a life event. The paper also compares its life event notion with the CPSV-AP Life Event class and concludes with a call for an ontological metamodel to support interoperability.

Significance. If the central claim were properly established, the paper would make a modest but useful contribution to the ontology of digital public services: it connects a current e-government policy concept (proactive life event services, as legislated in Estonia) with established foundational ontology distinctions, and it explicitly positions the proposal relative to [8], [14], and CPSV-AP. The paper is clearly written and grounded in the cited ontological literature, and it identifies a real tension between the reactive request-processing view of public services and the proactive, event-triggered services that are now being deployed. However, the contribution is conceptual and not validated empirically or formally: no axioms or formal constraints are given for the metamodel, and the key necessity claim is asserted rather than argued. The paper also makes no falsifiable predictions and provides no machine-checked formalization, so its value at this stage is mainly as a starting point for further ontological analysis.

major comments (4)

[Section 3, paragraph beginning 'In order to include proactive and life event services'] The central claim that it is necessary to change the definition of public service in [8] is not established. The paper's only stated reason is that in a proactive event service 'there may be a lack of a direct desire to use the service,' but the definition quoted from [8] is about requests and about giving people opportunities to control how and when capabilities are used; it does not mention psychological desire. An implicit or standing request, authorized by the citizen's assumed will and constrained by opt-out and admission rules, appears ontologically compatible with [8]'s request-processing structure. The paper gives no argument that such a reading is impossible or incoherent. If that reading is possible, then replacing request processing with initialization processing is a modeling choice, not a necessity, and the paper's central claim is overstated. The authors should either demonstrate a specific inconsistency between [8]'s notion of request and the Estonian regulation's notion of assumed will, or weaken the claim to an alternative modeling proposal and discuss the trade-offs.
[Section 3, definition of 'service initialization processing' and Figure 1] The new concept of service initialization processing is left substantially less defined than the notion of request processing that it replaces. The paper states that a life event triggers zero or more service initialization processing activities and that each such activity includes management and delivery activities, but it does not define what initialization means ontologically, who performs it, what its inputs and outputs are, or how it relates to the service offering activity and service admission activity. The admission rules and opt-out conditions, which carry the actual normative content of proactivity, could equally be conditions on a generalized request. The authors should provide a precise ontological characterization of service initialization processing, including its relationship to the notions of activity, interaction, and deontic assignment already used in the paper.
[Section 3 and Figure 1] The metamodel in Figure 1 is presented only as a diagram, with no formal axioms or constraints. In particular, the central relation 'life event triggers zero or more service initialization processing activities' is not formalized: no cardinality conditions beyond 'zero or more' are given, no conditions are specified for when a life event triggers zero versus one or more activities, and no relationship is defined between the trigger relation and the admission rules or opt-out mechanisms described in the text. Since the paper's conclusion calls for an ontological metamodel to support implementation and standardization, at least the key relations should be made precise enough to be operationalized.
[Section 3, discussion of 'assumed will'] The paper does not ontologically analyze the Estonian regulation's concept of 'assumed will,' even though this concept is the basis for the entire proactive service framework. It is unclear whether assumed will should be modeled as a standing disposition of a citizen, a social relator between citizen and state, a deontic assignment, or a form of consent. Without such an analysis, the paper cannot rule out the possibility that proactive services are representable within [8]'s request-based framework, because the request could be an implicit request grounded in assumed will. The authors should either provide an ontological analysis of assumed will or explicitly state that it is outside the scope and adjust the necessity claim accordingly.

minor comments (5)

[Section 2, paragraph on particulars] The sentence 'Each particle has a specific identity' should read 'Each particular has a specific identity'; the word 'particle' appears to be a typo.
[Section 2, paragraph on moments] The text first says moments are divided into 'internal moments and relator moments,' but then refers to 'An intrinsic moment.' The terminology should be made consistent (internal vs. intrinsic).
[Section 2, paragraph on phases] The example 'the subspecies Male has phases Boy, Teenager, and Adult Male' is presented without explaining whether these phases are ontologically exhaustive or mutually exclusive; a brief clarification would help.
[Section 3, CPSV-AP discussion] The acronym CPSV-AP is used without spelling out 'Core Public Service Vocabulary Application Profile' at first mention in the text (it is only spelled out in the reference list).
[References] Reference [1] links to a page that may be in Estonian only; the paper could state explicitly that the regulation defines 'assumed will' in the cited manner, to help readers who cannot access the original.

Circularity Check

0 steps flagged · score 0.0 of 10

No circularity found: the metamodel extends external sources [8] and [14], and the central 'initialization processing' proposal is a modeling choice, not a derivation from the paper's own inputs.

full rationale

The paper makes no empirical predictions and contains no fitted parameters or equations. Its central move in Section 3, replacing [8]'s 'service request processing' with 'service initialization processing', is presented as a conceptual revision ('In order to include proactive and life event services, it is necessary to change the definition of public service provided in [8]'), but this is an assertion about how to model proactive services, not a result derived from the paper's own definitions or from self-citations. The metamodel's foundations are external: [6] for ontological categories, [8] for public service, [14] for the ontology of ability and service, and [1] for the Estonian regulatory notions of proactive and event services. The author's own references ([7], [9], [10], [11], [12]) appear only in supporting roles, providing classifications such as deontic assignments, reaction rules, opt-out design principles, and proactive-service taxonomies; none of them carries the necessity claim. Even if the necessity claim is arguable, because an implicit or standing request might represent 'assumed will' within the original [8] definition, that is a substantive modeling debate rather than circularity: the conclusion is neither identical to the premises nor forced by them. No step in the paper reduces by construction to its own inputs, so the circularity score is 0.

Assumptions & free parameters 0 free parameters · 4 assumptions · 1 invented entities

The metamodel imports the full foundational ontology (endurants/perdurants, moments, types/roles) from Guizzardi and the service definition from Guarino. The only genuinely new content is the replacement of request processing with initialization processing, which is an unvalidated definitional move.

assumptions (4)

domain assumption Universals and particulars, endurants and perdurants, states and events, moments and relators are the correct ontological categories for services.
Section 2 adopts these from Guizzardi's foundational ontology without proof.
domain assumption Public service is a set of activities realizing an institutional agent's obligation to provide capabilities, per Guarino [8].
Section 3 uses this definition as the base ontology that the paper modifies.
domain assumption Proactive service is a direct public service provided on the institution's own initiative based on the assumed will of the individual and state database data (Estonian regulation [1]).
Section 3 imports this policy definition; the paper does not question its coherence.
ad hoc to paper A life event is an event that separates two states of affairs of at least one agent, and such an event should trigger service initialization activities.
Section 3 introduces this as the paper's central modeling decision; no external evidence or formal justification is given.

invented entities (1)

service initialization processing activity
purpose: Models the initiation of a proactive public service in the absence of an explicit citizen request, replacing Guarino's service request processing.
Introduced in Section 3 as a new element of the metamodel; not defined in [8] or [14], and no independent evidence or formal semantics is provided.

read the original abstract

Life event service is a direct digital public service provided jointly by several governmental institutions so that a person can fulfill all the obligations and use all the rights that arise due to a particular event or situation in personal life. Life event service consolidates several public services related to the same life event into one service for the service consumer. This paper presents an ontological analysis of life event services, which is based on the works by Guarino, Guizzardi, Nardi, Wagner, and others. The purpose of the ontological analysis is to understand the meanings of life event, proactive public service based on life event, and other related notions. This kind of ontological analysis is crucial because for implementing the hardware and software architectures of e-government and digital public services, it is essential to agree upon the precise meanings of the underlying terms.
