Dataset Card for sets_lego_omr_full

This dataset combines official LEGO sets from LDRAW OMR with metadata from Rebrickable. Each entry contains the full MPD file as a string plus associated metadata such as set number, name, theme, year, and parts count. It is intended for building LLM fine-tuning datasets for LEGO model generation tasks.

Dataset Details

Dataset Sources

OMR files: LDraw OMR Library
Metadata: Rebrickable
MPD file format: LDraw File Format

Uses

Direct Use

Fine-tuning LLMs to generate LEGO build instructions.
Research on programmatic generation of LEGO models.
Learning patterns between metadata (set info) and MPD structures.

Out-of-Scope Use

This dataset is not intended for commercial sale of LEGO sets.
The dataset is not a complete inventory of LEGO parts or pricing data.
Do not use this dataset to infer personal or sensitive information.

Dataset Structure

JSONL format.
Each entry contains:
- mpd_file: string (the full MPD file)
- set_number: string
- name: string
- theme_id: integer
- year_released: integer
- num_parts: integer
- other metadata fields available from Rebrickable CSV

Dataset Creation

Curation Rationale

To provide a unified dataset of LEGO models with full build instructions (MPD files) and metadata for LLM training tasks.

Source Data

Data Collection and Processing

Downloaded official LEGO sets from LDraw OMR.
Downloaded set metadata from Rebrickable CSV export.
Matched OMR sets with Rebrickable metadata via set number.
Saved combined data as JSONL: each line contains full MPD text + metadata.

Who are the source data producers?

OMR models are authored by the LDRAW community.
Metadata is curated by Rebrickable contributors.

Annotations

N/A — no additional human annotations added.

Personal and Sensitive Information

No personal or sensitive information is included.

Bias, Risks, and Limitations

The dataset only covers ~1,367 official LEGO sets available in OMR.
MPD files may vary in quality depending on the original author.
Metadata is limited to what Rebrickable provides.
Not all LEGO sets or MOCs are included.

Recommendations

Use this dataset primarily for training or testing models for LEGO build generation. Avoid using it for commercial purposes without consulting original authors.
