Versioned data original production

1. Scope and Applicability

This PCR covers the production of identified digital information content obtained by accessing and observing phenomena and recording, organizing and storing their information. The output is one complete versioned data original under identified ownership/control, usable as input to productive activities. It covers primary observations and compilation of traceable existing data; the declared actual route determines the foreground inventory. Examples include a scoped weather-observation database and an identified business-record compilation. The object is the information product, including its schema, provenance, documentation and required quality results, rather than a file format or a sale. [un-cpc3-data; w3c-dcat3; noaa-ghcnd]

Exclude database-management software and other software originals, physical storage media, crypto assets, brands/franchises, research or exploration conclusions as separate originals, entertainment/online consumption content, commissioned compilation activity sold solely as a service, downloads and continuing access/hosting services. A research project may produce a data product as a separable output; do not reclassify its entire scientific original as data. A digital file can carry data without its creation constituting a new data original. [un-cpc3-data; w3c-dcat3]

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.business-and-production-services.data-products.versioned-data-original
classification_refs	CPC 3.0: 83710 Data
covered_products	Versioned productive digital information originals and original databases, with a bounded content manifest
excluded_products	Software; physical media; crypto assets; research/design originals; consumption content; compilation services; downloads and hosting
representative_product	One identified observation-data database version, with declared variables, population/locations, period, quality flags and reuse conditions; GHCN-Daily demonstrates version citation, not a mandatory weather route
production_route	Specify content and collection design; acquire/observe and record; integrate and organize; validate/correct; document and seal one original
market_state	Completed digitally stored information original available for declared productive reuse; ownership/control and access restrictions are specified

3. Reference Flow

Field	Value
What	Produce a retrievable, documented digital information original for the declared productive purpose
How much	One complete original package of the declared content/version; 1 item
How well	Actual acceptance specification for variables/schema, coverage, completeness, resolution, quality flags, provenance, integrity and permitted reuse; no invented accuracy threshold
How long or cycle	One bounded creation cycle from project inception to the declared sealed-version cutoff; observation coverage is distinct from production duration; no default asset lifetime
reference_flow_link	reference_data

Field	Value
Reference amount	1
Reference product flow	Versioned data original package
Reference flow property	Number of items 01846770-4cfe-4a25-8ad9-919d8d378345
Reference unit group	Units of items 5beb6eed-33a9-47b8-9ede-1dfe8f679159
Reference unit	item
Required qualifiers	original ID; version and content manifest; schema/variables; source provenance; population/spatial and temporal coverage; resolution; missingness and quality flags; acceptance and integrity results; ownership/control and reuse rights; production route and sites; creation period and cutoff; upstream-data reuse and provider boundary

The display unit item is exactly the public count unit Item(s); it is not mass, money, a user or a byte. Required qualifiers belong in the resulting dataset metadata and acceptance evidence. One count without defined content/quality is not a comparable data product. Alternative serializations and duplicate backups of the same content are not additional originals.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_count	reference product	Number of items 01846770-4cfe-4a25-8ad9-919d8d378345	item	Exactly one complete declared original; count by signed content/version manifest with cp_original. No mass conversion, byte normalization or license multiplication.
electricity_unit	electricity rows	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Preserve the public reference property and Units of energy group 93a60a57-a3c8-11da-a746-0800200c9a66. Meter kWh; convert to MJ with 3.6 MJ/kWh in calculate_energy [nist-si-conversion].
information_metrics	content and allocation metadata	Recorded count/capacity/time in its actual unit	item; byte; s as separately recorded	Record actual bytes, records, reserved time and transmitted data as separate metrics; no universal relation to item quality or electricity.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual observation access/collection inception, or receipt of identified existing data, through sealed original completion
starting_condition_role	Declared original-creation foreground gate; receipt of existing data does not erase upstream creation
product_classification_scope	Productive information content in the CPC Data sense, independently of file format
recursive_input_rule	Record each reused source-data version as a distinct input with provenance and a conserved upstream-burden share. Stop at its declared upstream dataset; never recalculate the same observations inside the consuming original
upstream_dataset_requirement	Supplier data-creation, grid supply, owned hardware and purchased-job inventories matched to actual scopes; missing links are disclosed rather than set to zero
disclosure	Creation/observation periods; source cutoffs and prior versions; owned/provider interfaces; physical collection route; hardware, cooling, storage and network boundaries; exclusions and missing upstream layers

rule_id	Applies to	Rule	source_ids
boundary_cycle	all production stages	Include attributable planning, access, observation/recording, ingestion, organization, validation, corrective reruns, documentation and storage up to original sealing. Record failed runs and discarded records as production activity, without counting them as accepted output.	un-cpc3-data; unece-gsbpm52
boundary_physical	observation	Map every actual field, laboratory, survey, sensor and scanning route. Add separate specific exchanges for actual fuel, transport, each reagent/consumable, water, wastes and documented direct releases. Their absence needs route evidence. Electronic data output does not justify excluding its physical collection.	un-cpc3-data; unece-gsbpm52
boundary_assets	computing and instruments	Include the attributable inventory of identified owned devices outside provider inventories. Hardware production/disposal is an upstream layer, not a local elementary release. Cooling, network and temporary storage inside creation must be metered or supplied by a scoped provider inventory.	gsf-sci110
boundary_after_gate	copies and operations	Post-sealing downloads, user access, long-term hosting, updates and data use are separate processes. Initial creation burdens enter downstream through an explicit reuse ledger, never the full original cost in every download. New content versions include actual incremental work and disclosed reused burdens.	un-cpc3-data; w3c-dcat3

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
planning	Content and collection design	required	All originals; actual design/build workload	original creation	per declared reference flow
observation	Acquisition and recording	required	Actual source access and recording; owned physical collection only where used	original creation	per declared reference flow
organization	Integration and organization	required	Actual schema mapping, cleaning, indexing and processing; transformations are route-specific	original creation	per declared reference flow
validation	Quality and integrity checks	required	Checks against declared acceptance rules; no universal imputation requirement	original creation	per declared reference flow
sealing	Documentation and original sealing	required	One complete version manifest and bounded storage cutoff	original creation	per declared reference flow
infrastructure	Owned supporting devices	conditional	Owned devices support creation and are outside purchased-provider inventories	original creation	per declared reference flow

Each row represents one exchange. Process electricity pools are disjoint. Empty waste/elementary subsections mean no universal release is prescribed, not that a real site has zero exchanges. Dataset production must instantiate all documented route exchanges required by boundary_physical; purchased electricity emissions occur in its upstream supply inventory.

Count completed jobs from logs, not billed currency; omitted cooling/hardware/storage/network must be supplied separately. Replace the same embedded energy/device exchanges rather than adding them twice.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide	shared data projects	Separate project and stage workloads using meters, collection logs and job IDs before allocating. Keep residual unassigned shares and failed work visible. Do not default to revenue, licenses, users or data byte shares without a causal measured relationship.	gsf-sci110; unece-gsbpm52
allocation_compute	shared electricity	Reconcile attributable measured job/storage/network shares to the same facility meter period, including reserved idle and cooling scope. A traffic or storage metric is an attribution driver requiring justification and reconciliation, never a universal kWh conversion.	gsf-sci110
allocation_device	server_hardware; logger_hardware	Use the actual device inventory fraction attributable to the creation cycle. For a reserved computing device, use reserved time divided by evidenced installed life and reserved resource divided by total resource. Noncomputing sensor duty allocation needs its own measured causal utilization evidence. Do not invent life or duplicate provider hardware.	gsf-sci110
allocation_reuse	source_data and joint original versions	Trace upstream source content and retained prior-version work separately from incremental creation. Maintain a conserved beneficiary ledger with an explicit finite output/use scenario when sharing original burdens downstream; report sensitivity to reuse assumptions. Copies never multiply information creation. Joint research/software outputs require actual subdivision; unresolved joint attribution needs review.	un-cpc3-data; w3c-dcat3

8. Foreground Data Collection, Calculation, and Quality Rules

Data Collection Protocols

protocol_id	process_id	flow_role	record_type	raw_fields	collection_method	unit	frequency	temporal_coverage	site_scope	aggregation_rule	quality_evidence
cp_original	sealing	reference output	acceptance_record	original ID; version; files/checksums; content extent; schema; source rights/control; acceptance criteria/results; coverage; quality flags; completion cutoff; complete count	Inspect original content and producer acceptance records; deduplicate equivalent serializations and bind one complete declared original	item	At version completion	Entire declared creation cycle	All original-producing sites/providers	per declared reference flow	Signed version manifest and reproducible acceptance/integrity results
cp_energy	planning; observation; organization; validation; sealing	stage electricity	meter_record	meter ID; start/end; stage/job; region; voltage; kWh; reserved/idle load; cooling, storage and network interface; allocation share; provider overlap	Use calibrated meters or verified telemetry reconciled to facility totals; bind disjoint stage intervals, reruns and shared-load attribution	kWh	Each run and creation interval	Full creation cycle including failed work	Actual owned supply; provider scopes separately	per declared reference flow	Calibration, workload logs, meter reconciliation and gap coverage
cp_source	observation	existing observation dataset	source_record	source ID/version; package count; variables/coverage; flags; rights; upstream creation inventory; beneficiary shares; received bytes; lineage	Inspect received original and provenance; count defined packages; verify compatibility, rights and upstream burden ledger rather than estimating energy from size	item	Each source version received	All sources of the declared output version	Actual suppliers and receiving site	per declared reference flow	Source manifest, access record, upstream inventory and reuse ledger
cp_provider	organization	compilation job	provider_record	job ID; source/output version; complete-job count; transformation; resources/time; provider energy/device/network/storage/cooling boundary	Inspect provider job acceptance logs and matched job inventory; retain retries and scope exclusions, reconcile billed metrics without treating money as quantity	item	Each completed provider job	Declared creation cycle	Actual provider facilities	per declared reference flow	Job manifests, scoped provider inventory and embedded-exchange exclusion ledger
cp_device	infrastructure	individual device	asset_record	device model/configuration; upstream inventory; installed life; reserved time; reserved/total resources; actual sensor duty; calibration; replacements; provider inclusion	Inspect device register, configuration, service-life evidence and utilization logs; collect causal shares separately for servers and instruments	item	Each device and project period	Creation cycle and evidenced device life	Actual owned devices	per declared reference flow	Asset records, utilization evidence and life/allocation sensitivity

For physical observation, retain the actual method, sampling/survey coverage, equipment and calibration, field/laboratory locations, collection period and all individual input/output records. Every added atomic exchange must have a linked protocol with its real property/unit, method, coverage and the same per-original basis. Route omissions block a complete dataset; digital-only compilation requires evidence that observation burdens are in its identified upstream sources.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calculate_energy	planning_electricity; observation_electricity; organization_electricity; validation_electricity; sealing_electricity	Convert attributable metered kWh to MJ by multiplication by 3.6; preserve stage and supply interfaces.	cp_energy; kWh	MJ	gsf-sci110; nist-si-conversion
calculate_original	all inventory rows	Sum nonduplicated attributable exchange quantities for the one declared original after stage/provider/source subdivision; the output is exactly 1 item. Keep numerator units and upstream shares explicit.	cp_original; cp_energy; cp_source; cp_provider; cp_device	per declared reference flow	un-cpc3-data; gsf-sci110
calculate_metrics	content metadata	Record actual completeness, valid/rejected record counts, byte sizes and coverage against declared specifications. These characterize content and do not transform bytes or records into MJ or new originals.	cp_original; source and validation logs	declared quality and content metrics	w3c-dcat3; unece-gsbpm52; noaa-ghcnd

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_content	reference_data	Bind source lineage, coverage, version, schema, missingness, flags, transformations and rights/control. Preserve observed versus imputed records and checks actually performed; acceptance criteria are producer-specific.	cp_original; cp_source; w3c-dcat3; noaa-ghcnd
quality_cycle	all processes	Cover actual sites, collection and production periods, failed jobs, corrections, temporary replicas and sealing storage. Disclose missing meter periods, external source burdens and provider exclusions.	cp_energy; cp_provider; unece-gsbpm52
quality_identity	all inputs	Recheck public identities, reference properties/groups, supply conditions, actual hardware and upstream versions. Blank UUIDs remain candidate gaps and cannot establish available provider inventories.	cp_device; cp_source; cp_provider
quality_uncertainty	allocation and data representativeness	Report workload/meter uncertainty, unknown shares, hardware-life sensitivity, observation coverage limits and reuse scenario sensitivity. No invented benchmark can replace foreground evidence.	cp_energy; cp_device; source/reuse ledger

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_product	reference_data	Require one complete identified productive information original with actual ownership/control and declared quality evidence. Reject copies, licenses, file-format conversions, mere compilation services, software or consumption content counted as equivalent originals.	un-cpc3-data; w3c-dcat3
validate_basis	all inventory rows	Require consistent per declared reference flow in both languages, linked collection records, count output and numerator-unit preservation. Reject arbitrary mass, bytes-to-kWh or money-to-item conversions.	gsf-sci110; w3c-dcat3
validate_route	observation and processing	Fail dataset completeness if any actual observation route, provider interface, utility, material, waste, direct release or upstream source burden is unknown or omitted. A conditional row may be absent only with route evidence; do not invent emissions to fill empty subsections.	un-cpc3-data; unece-gsbpm52
validate_conservation	shared work and reused content	Reconcile stage meters, provider embedded flows, device shares, joint outputs and the finite reuse ledger. Reject duplicated original costs per copy and unexplained allocation residuals hidden as zero.	gsf-sci110; w3c-dcat3
validate_coverage	dataset claim	List checks performed/skipped, missing physical and upstream layers, identity gaps and uncertainties. Foreground creation alone is not a complete cradle-to-gate or lifecycle result; metadata conformance is not scientific, privacy or legal approval.	un-cpc3-data; w3c-dcat3; gsf-sci110

10. Published Dataset Profile

Field	Value
dataset_role	Original-creation foreground inventory for one declared complete data product version
downstream_use	secondary_dataset; background_dataset
allowed_use	After evidence completion, traceable upstream data product input with explicit source/reuse allocation and matched content quality
excluded_use	Generic impact per byte/user/license/revenue; comparisons of unequal data; full lifecycle claims from foreground alone; approved accuracy or legal status
required_metadata	All reference qualifiers; sites and periods; method/route register; source lineage and upstream inventories; provider and owned-asset scopes; meters/units; reuse allocation and sealing cutoff
required_quality_disclosure	Identity and route gaps; data coverage/missingness; actual acceptance results; meter/allocation uncertainty; device-life and reuse sensitivity; skipped layers
