Description Rules

General

• Be thorough — especially things hard to see in photos
• Write out full words, no abbreviations (for Google SEO)
• Always include: creator, material, manufacturer, measurements, weight (where applicable)
• Provenance, exhibitions, literature: write before measurements

Abbreviation Rules

• "bl a" → "bland annat"
• "osv" → "och så vidare"
• "NS" → "nysilver"
• "ca" before year → use "omkring" instead
• "st" only accepted in titles (for piece count), not in descriptions

Period/Dating Rules

• Prefer specific decades over vague centuries (e.g., "1920-tal" over "1900-tal")
• Prefer "senare fjärdedel", "senare hälft", "slut" over vague period expressions
• Use "omkring" instead of "ca" for approximate years

Measurements

• Format: Höjd 84, bredd 47 cm or Längd 84, bredd 47, höjd 92 cm
• NEVER repeat the unit: Höjd 84 cm, bredd 47 cm is WRONG
• Art: 45 x 78 cm (height × width, without frame)
• Always last in description (except rugs/ceiling lamps → in title)
• Use "ca" for approximate measurements
• Graphics: clarify "bladstorlek" vs "bildstorlek"
• Rings: only ring size, no measurements

Services Description

• No measurements needed
• List all pieces: 34 mattallrikar, 25 djupa tallrikar, såsskål samt tillbringare
• Single items NOT preceded by "1" — just name them
• No "st" after single items

Condition Report Rules

Dos

• Be thorough when possible, vague when necessary
• Always use "Ej examinerad ur ram" for framed art
• Always mention engravings/monograms on silver
• Use "Ej genomgånget" for books and similar
• Always photograph visible damage

Don'ts

• NEVER use "bruksslitage" as standalone condition — specify damage type
• NEVER use "Ej funktionstestad" — implies we test items
• AVOID "Ingen anmärkning" — leads to complaints
• NEVER comment on frame condition (unless the frame IS the item)
• Avoid abbreviations: mm, bl a, osv
• Paintings don't have "bruksslitage" — they're not "used"

Preferred Specific Terms

Keyword Rules

• Min 3, max 12 keywords, space-separated
• Hyphenate multi-word terms (e.g., art-deco)
• Must complement (not duplicate) title and description
• No keywords = -30 points (highest single penalty)

Field Validation Thresholds

Additional Validation Rules

• Reserve ≥ estimate: -20 points (reserve must be lower than estimate)
• Sterling silver: write as one word "sterlingsilver" (not "Sterling Silver")
• Title capitalization: if artist field filled → title starts proper case; if empty → starts UPPERCASE
• Repeated measurement units: "Längd 84 cm, bredd 47 cm" is WRONG → "Längd 84, bredd 47 cm" (unit only once at end)
• Unknown artist phrases: oidentifierad konstnär, okänd konstnär, okänd mästare, etc. → flag and direct to artist field

Forbidden Meta-Phrases (indicate poor cataloging)

• "ytterligare uppgifter behövs"
• "mer information krävs"
• "information saknas"
• "kan förbättras"
• "bra start"

Category-Specific Rules

Watches (armbandsur)

• Function clause required: "Fungerar vid katalogisering - ingen garanti lamnas pa funktion"
• Include: brand, model, movement type, case material, diameter, reference number if visible

Weapons & Militaria

• Extra anti-hallucination caution — never fabricate historical context
• Conservative approach: only state what is verifiable from the item itself

Jewelry (smycken/adelmetaller)

• Technical limitations: cannot verify gemstone authenticity from photos
• Always note: "Auctionet garanterar inte äktheten hos stenar"
• Include hallmarks, weight, stone description as visible

Historical Items (antikviteter)

• Conservative dating — prefer broader ranges over specific dates when uncertain
• Never add historical narrative not supported by the item itself

AML Compliance (quality-rules-engine.js)

• Items valued over 50,000 SEK: trigger AML reminder for seller risk profile/ID verification
• Bullion/gold lots (guldtacka, silvertacka, parti guldmynt): document seller identity and ownership duration
• Loose gemstones: additional scrutiny required

Compound Words (never combine)

Incorrect → Correct: majolikavas → majolika, vas | keramiktomte → keramik, tomte | kristallvas → kristall, vas | porslinsvas → porslin, vas | guldring → guld, ring | silverkedja → silver, kedja | massingsjusstake → massing, ljusstake | tennmugg → tenn, mugg
