RAÄ

RAÄ is intended to supply dense, Sweden-specific archaeology context from Riksantikvarieämbetet's published Fornsök/Open Data surfaces. The repository retains capture metadata and derived density files for audit, but does not currently admit or publish them as governed archaeology evidence. RAÄ authority is refused until the raw inventory, raw summary, normalized counts, and qualified scientific review reconcile.

Checked-In Evidence

Surface	Current state	Meaning
source inventory denominator	unavailable	no admitted raw inventory and raw summary reconcile the retained metadata
classified-record denominators	unavailable	retained summary values are not governed evidence while authority is refused
density cells	retained but excluded	the derived one-degree surface is audit material, not an admitted public layer
temporal evidence	not applicable	the refused density surface cannot contribute dated evidence or same-period comparison

Missing governed denominators are not scientific zeros. The refusal means the repository cannot currently establish which source population the retained density cells represent or authorize those cells for analytical or public use.

Read A Density Cell

A retained cell could answer a bounded question only after authority admission: how many governed RAÄ records in the selected class fall within this aggregation area? In the current refused state it establishes none of the following:

• a complete inventory of past activity;
• uniform survey or registration effort;
• chronology shared by records inside the cell;
• association with a nearby pollen, lake, fieldwork, or aDNA feature; or
• site-level distance from a feature to every contributing record.

Cell size is part of the result. A one-degree aggregation supports broad national or regional context, not precise local-distance reasoning. Rendering the cell with a smooth color ramp does not increase spatial resolution.

Aggregation Contract

Layer	Observation unit	Defensible denominator	Spatial meaning
source summary	published RAÄ registry record	unavailable while authority is refused	national registry population represented by an admitted capture
classified summary	record in a declared RAÄ class	the selected classification population	classification count, not event count
density layer	one-degree cell	unavailable while authority is refused	aggregate registry density within the cell
map rendering	colored cell polygon	no cells currently admitted	visual comparison only after authority admission

The transformation changes the observation unit. A statement about a density cell must cite the cell and classification contract; a statement about an individual RAÄ record requires the source record, which the public density surface does not expose.

Retain The Aggregation Receipt

A density comparison is reusable only when the aggregation choices travel with the cell value:

Receipt field	Required meaning
source population	governed RAÄ capture and source classification included
membership predicate	rule assigning source records to cells
grid definition	cell geometry, resolution, coordinate reference system, and boundary convention
numerator	count of admitted registry records in the named cell
denominator	selected source population or comparison-cell population used by the claim
missing and duplicate posture	treatment of unusable geometry, repeated identities, and multi-part records
product identity	publication version and stable cell identifier

    Receipt --> Context["qualified archaeology-density context"]

Two cells are comparable only under the same source population, classification, grid, and membership rule. Equal color classes from different contracts are visually similar, not necessarily quantitatively comparable.

Audit An Archaeology-Density Claim

1. Confirm that RAÄ authority has been admitted; the current repository state is refused and cannot support an archaeology-density claim.
2. After admission, identify the Sweden product, RAÄ layer, cell, and classification being read and confirm that its counts share one capture.
3. Treat the cell value as an aggregate count, not a site-level distance or a chronology statement.
4. State the one-degree spatial support and Sweden-only reach.
5. When comparing with SEAD, retain both observation units and do not add their counts into one archaeology population.
6. For a stronger local or temporal claim, return to the appropriate source records rather than interpolating detail from the color scale.

Relationship To SEAD

Dimension	RAÄ	SEAD
reach	Sweden-specific	broader environmental-archaeology context
current public geometry	none while authority is refused	normalized site points
temporal posture	refused; no admitted time dimension	mixed site envelopes: numeric where linked chronology supports them, otherwise label-only or unresolved
strongest use	retained provenance pending authority admission	wider site-centered archaeology context
invalid shortcut	generalize Swedish density to the Nordic region	infer same-period evidence from undated proximity

The families are complementary and must not be merged into one archaeology denominator. Their observation units, geographic reach, spatial resolution, and capture depth differ.

Governing Surfaces

• data/raa/raw/arkreg_v1_0_wfs_capabilities.xml preserves service capability context;
• data/raa/raw/publicerade_lamningar_centrumpunkt_schema.xml preserves the captured feature schema;
• data/raa/raw/fornsok_domains.json preserves governed domain values;
• data/raa/normalized/sweden_archaeology_layer.json governs counts, cell size, classification, and source identity; and
• data/raa/normalized/sweden_archaeology_density.geojson governs the visible density geometry.

Public maps must exclude the RAÄ density surface while authority remains refused. Continue to RAÄ exports for the publication role and source comparison before combining RAÄ with another family.
