# Data Dictionary — Temu E-commerce Pricing & SKU Variant Dataset
**Version:** 2.0.0 | **Provider:** Octoparse Managed Data Service

---

## Table: `products.parquet`
One row per Temu product listing (SPU). Contains product-level metadata.
**85 rows.**

| Field | Type | Example | Business Context |
|---|---|---|---|
| `spu_id` | string | `"606068486800016"` | Temu's Standard Product Unit ID. Use as join key with `skus.parquet`. Stored as string to prevent int64 overflow. |
| `product_url` | string | `"https://m.temu.com/product-g-606068486800016.html"` | Canonical mobile URL. Append to any Temu domain for desktop. |
| `is_on_sale` | boolean | `True` | Whether the product is currently purchasable. All 85 products in this sample are active. |
| `not_on_sale_reason` | string | `"Unavailable for purchase"` | Only populated when `is_on_sale=False`. Null for all active products. |
| `goods_property_summary` | string | `"Material:Polyester;Style:Casual;Season:Summer"` | Semicolon-delimited key:value property bag. Keys vary widely across products (~178 unique keys). Useful for taxonomy building. Parse defensively (typos present, e.g. `"Seasoon"`). |

## Table: `skus.parquet`
One row per SKU (product variant). Foreign key `spu_id` joins to `products.parquet`.
**382 rows, avg 4.5 SKUs per product.**

| Field | Type | Example | Business Context |
|---|---|---|---|
| `sku_id` | string | `"17592356187455"` | Temu's variant-level ID. Unique per color/size/style combination. |
| `spu_id` | string | `"606068486800016"` | FK → `products.spu_id`. |
| `sku_main_pic` | string | `"https://aimg.kwcdn.com/..."` | CDN URL for the SKU's primary image. URLs are static (not signed). Use for visual product matching or multimodal AI pipelines. |
| `sku_original_price` | float64 | `12.99` | Strikethrough list price in USD. **Null for ~69% of SKUs** — Temu only renders this when actively showing a "was/now" comparison. Absence ≠ no discount; it means Temu isn't surfacing the comparison at this moment. |
| `sku_discounted_price` | float64 | `4.89` | Current selling price in USD at scrape time. Range: $2.14 – $219.72. |
| `discount_pct` | float64 | `0.6235` | Computed: `(original − discounted) / original`. Only populated when both prices present (120/382 SKUs). Use `log1p` transform for modeling. |
| `sale_attr_color` | string | `"Black"` | Color variant label. May bundle quantity (e.g. `"Red Rose Vine - 3pcs"`). |
| `sale_attr_size` | string | `"6.5-7"` | Size variant. Format varies: numeric (`8`), range (`6.5-7`), children's age (`3-4Y`), clothing (`XL`). Normalize before comparison. |
| `sale_attr_quantity` | string | `"1pc"` | Quantity or bundle label. Highly variable — ranges from `"1pc"` to full product descriptions. Not reliably machine-parseable as numeric. |
| `sale_attr_capacity` | string | `"500ml"` | Volume/storage capacity. Sparse (<1% populated). |
| `sale_attr_model` | string | `"Standard"` | Product model variant. Sparse (~2% populated). |
| `sale_attr_style` | string | `"Modern"` | Style variant. Sparse (~1% populated). |
| `sale_attr_compatible_model` | string | `"iPhone 15"` | Device compatibility for accessories. Sparse (~1% populated). |
| `sale_property_summary` | string | `"Color:Black\|Size:XL"` | Pipe-delimited summary of all non-null `sale_attr_*` values for this SKU. Prefer this over individual columns for display or search. |

## Derived Metrics (compute on demand)

| Metric | Formula | Use Case |
|---|---|---|
| Discount Rate | `discount_pct` (precomputed) | Price competitiveness signal |
| SKU Count per Product | `COUNT(sku_id) GROUP BY spu_id` | Variant complexity scoring |
| Price Spread per Product | `MAX(sku_discounted_price) - MIN(sku_discounted_price) GROUP BY spu_id` | Dynamic pricing range per SKU matrix |
| Has Strikethrough Price | `sku_original_price.notna()` | Promotion detection filter |

## Key Data Limitations

| Issue | Detail |
|---|---|
| `sku_original_price` sparsity | 68.6% null — Temu algorithmically controls when strikethrough prices are shown |
| `sale_attr_*` mutual exclusivity | Each SKU uses at most 1–2 of 7 attribute columns; remaining are null |
| Price is a snapshot | No historical cadence in this sample — prices change frequently on Temu |
| `goods_property_summary` key inconsistency | ~178 unique keys, some duplicated under different spellings |
