Schema Reference

Core fields shared across all dataset categories. Every entry conforms to this base schema, with category-specific and modality-specific extension fields layered on top. Built for direct ingestion into RAG pipelines, fine-tuning workflows, and evaluation frameworks.

entry_id
string
Unique identifier. Format: hmd_{category_code}_{id}. Stable across dataset versions.
e.g. "hmd_meal_004217", "hmd_voice_000892"
category
string
Dataset category. One of 11 defined values covering all domestic knowledge domains.
e.g. "meal_planning_nutrition", "voice_commands_smart_home"
modality
string
Data modality: text, audio, vision, or multimodal. Enables modality-specific filtering at query time.
e.g. "text", "audio", "vision", "multimodal"
household_profile
object
Household demographic data: size, composition, income band, region, and cultural context. Enables precise demographic filtering.
e.g. { "size": 4, "income_band": "45000_65000", "region": "southeast_us" }
expert_validation

e.g. ["energy_reduction_opportunity", "childcare_high_pct"]
qa_pairs
array
Array of 2–6 question/answer objects derived from the structured entry. Pre-formatted for fine-tuning and RAG retrieval. Each pair includes context metadata.
e.g. [{ "q": "How should...", "a": "For a family...", "tags": [...] }]
decision_tree_ref
string
Reference ID to an associated decision tree document (Professional+ plans). Links structured data to branching reasoning logic for RAG and agentic workflows.
