Ontology

Pre-release. This site describes standard version 0.1.0-dev, which is in development and may change before version 1.0.0.

Nova Waste Service Standard — Ontology

The OWL extension of the Nova Waste Service Standard (NWSS), an Independent Impact impact standard for community waste services. Contains only the nwss-unique classes and predicates for waste service activities, service points, zones, facilities, containers, tags, records and observations; every other term is reused from the AIA Ontology Suite, the Independent Impact platform vocabulary, the Indicator and Methodology Ontologies and Dublin Core.

Classes

Characterisation record

What a waste characterisation left for one sampled service point: the period its waste was kept, and weighed quantities by material category.

Kind of: Record

Property	Kind	Range	Meaning
accumulation days	datatype	decimal	Days over which the sampled service point’s waste was kept before it was characterised.

Collection round activity

A collector’s visits to service points on a service day, each leaving a service outcome. The collector’s trail stays in the evidence store (ADR-0004).

Kind of: Waste service activity

Property	Kind	Range	Meaning
on service round	object	Service round	The service round a collection round activity worked. A round that passed a service point’s zone and left no service outcome for it is evidence of a missed service (service point lifecycle workflow).

Contamination observation

An observation, in a contamination audit, of the streams found in one sampled bag or container of an audited stream.

Kind of: Observation

Property	Kind	Range	Meaning
audited stream	object	Concept	The separation stream the sampled bag or container was presented as.
stream found	object	Concept	A separation stream whose material was found in the sample. Any stream other than the audited one is contamination; none found is recorded as no value.

Enrolment record

The record of a participant enrolment visit: the contact outcome, the respondent’s eligibility, the participant in a service point relationship and the decision. Only a signed decision enrols the service point; the signed document stays in the evidence store (ADR-0004).

Monitoring period

The interval over which a registered project’s service delivery, separation quality and diversion claims are verified. Records observed in it are its evidence. A record submitted after the period’s latest service delivery review is marked submitted after review and does not reopen it; a late observation is one whose service period had already closed when it was submitted, and changes no fixed status (ADR-0005).

Kind of: Waste service activity

Organic treatment record

The record of organic material composted or otherwise treated, with its weighed quantities and destination. Evidence for diversion of organic mass.

Kind of: Record

Participant enrolment activity

A visit to a service point at which a participant decides whether to take part in the service. Leaves an enrolment record; only a signed decision enrols.

Kind of: Waste service activity

Participant response

What a participant reported at a service point evaluation: satisfaction, perceived change, disposal practices, whether the service came. The participant (an agent IRI) is the claimant; the evaluator recorded it. An opinion or self-report, never an observation of the evaluator’s.

Kind of: StateClaim

Property	Kind	Range	Meaning
disposal practice	object	Concept	A practice the participant reports for the response’s stream, from the disposal-practices scheme. Several may apply.

Project design

The project’s declaration of its service areas, parties by role, monitoring plan and the parameters the standard leaves to it (ADR-0010). Validated before it becomes a registered project version; a change is a new design that supersedes the old, never an edit.

Property	Kind	Range	Meaning
accumulation period in days	datatype	integer	Days a sampled household keeps all its waste for a waste characterisation. Default 7. Each characterisation record states the days actually kept (accumulation days).
carry-forward window in days	datatype	integer	Days after a period’s scheduled service day during which a visit still counts for that period; the period closes when it has passed (ADR-0005). Default 8.

claims diverted stream	object	Concept	A separation stream the design claims as diverted. Mass in it counts as diverted only with a recorded recovery destination (ADR-0008). A design that names none makes no diversion claim.
declares service area	object	Service area	A service area the project serves. Service points and facilities come under the design through the area they lie in.
declares stream override	object	Stream override	A stream override the design declares. Default: none.
deployment success criterion	object	Concept	A condition a container deployment must meet to count as successful, from the deployment-success-criteria scheme. The criteria a design declares replace the default: a tagged container placed.

follow-up window in days	datatype	integer	Days after a period’s scheduled service day within which a missed-service follow-up counts. Default 7.
has monitoring plan	object	Monitoring plan	The monitoring plan the design declares.
material category level	datatype	positiveInteger	The level of the material-categories scheme the project weighs at, counted from the top: 1 is the material family, 2 the next narrower level, and so on. Default 1.
newly-placed window in days	datatype	integer	Days before a period’s scheduled service day within which a first successful deployment makes the service point newly placed rather than missed. Default 8.
reports generation-based rate	datatype	boolean	When true, the project reports a rate based on the waste households generate, which needs a waste characterisation baseline in each service area (ADR-0008).
service period	datatype	duration	The length of the interval a recurring service is judged over, as an xsd:duration. Default P7D: an ISO week starting Monday, in the project’s time zone.
supersedes design	object	Project design	The earlier project design this version replaces. The earlier design is withdrawn on registration, never edited.
time zone	datatype	string	The IANA time zone name (for example Africa/Johannesburg) in which the project’s local dates, service periods and service days are read. No default.

restatement reason	datatype	string	The observer’s reason for restating: what was wrong or missing in the record restated.
restates	object	Record	The earlier record of the same type this record replaces, taking its time slot. The earlier record stays as it was; of several restatements the latest governs (ADR-0006). A record bearing this property is a restatement.
visit outcome	object	Concept	Whether the visit reached a suitable respondent at the right service point, from the visit-outcomes scheme. Attempts are records too.

Residual disposal activity

Delivering residual material from a facility to a disposal site. Leaves a residual disposal record.

Kind of: Waste service activity

reviewer must not have collected	datatype	boolean	When true, the reviewer may not have collected any collection round, evaluation or audit that contributes to the reviewed claim. An evaluator never reviews service points on a round they collected (ADR-0004).
seat policy	object	Concept

Kind of: Environment

Property	Kind	Range	Meaning
in service zone	object	Service zone	The zone a service point is explicitly assigned to. Geometry only checks the assignment; it never assigns (ADR-0002).
land parcel	object	Land parcel	A cadastral parcel the service point is aligned to, where the project declares a cadastre.

service outcome	object	Concept	What the collector observed on the visit, from the service-outcomes scheme.

Service round

Property	Kind	Range	Meaning
scheduled service day	datatype	integer	The day of each service period on which the round serves its zones, as an ISO 8601 weekday number (1 is Monday, 7 is Sunday). Set in the project design for every round.
serves zone	object	Service zone	A zone a service round covers.

Service zone

A polygon grouping service points for service. Its identity never changes; its boundary and label are carried by versions. A split or merge creates new zones that point to their predecessors.

Kind of: Environment

Property	Kind	Range	Meaning
predecessor zone	object	Service zone	A zone that a split or merge replaced with this one. The new zone never inherits the old identity.

Service zone version

One immutable boundary and label of a service zone, valid from a date until a later version replaces it.

Property	Kind	Range	Meaning
function source	datatype	string	Illustrative source of the Fluree smart function by which the ledger enforces the check.

Stream override

A project design’s assignment of one material category, and its narrower categories, to a separation stream other than its default (ADR-0007). The category itself never changes.

Property	Kind	Range	Meaning
override category	object	Concept	The material category the override applies to, from the material-categories scheme; never the uncategorised concept.
override stream	object	Concept	The separation stream the overridden category belongs to under the design, from the separation-streams scheme.

Tag

A printed code, usually QR, that bears an identity without being it. A scan resolves to whatever the tag was assigned to at the time of the scan. A scan in a gap between two assignments resolves to the entity of the assignment before the gap when the code was never assigned again or was next assigned to that same entity; otherwise it stays unresolved (ADR-0003).

Kind of: Thing

Property	Kind	Range	Meaning
tag code	datatype	string	The code printed on the tag, unique in its print run. Carries a token, never the urn:uuid of what it bears.

Tag assignment

A dated link from a tag to the thing it bears, valid from assignment until a later assignment supersedes it. An entity has at most one active tag and a tag at most one active assignment. A tag bearing a collector is held in the people register, not the graph (ADR-0003). Platform candidate.

Kind of: Waste service activity

Waste characterisation activity

Sampling waste and weighing it by material category to establish its composition, as a baseline for a generation-based indicator.

Kind of: Waste service activity

Waste service activity

The abstract superclass of every activity type NWSS covers. Common data requirements target this class; per-type requirements target its subclasses.

Kind of: Activity

Kind of: Record

Property	Kind	Range	Meaning
withdrawal reason	datatype	string	Why the withdrawn record’s event is held never to have happened.
