# Converted Robotics Dataset This dataset stores authoritative timestamps and metadata in Parquet tables and stores frame payloads in video containers. Video presentation timestamps are not used for synchronization; use `tables/frames.parquet` and `video_frame_idx`. Core loading rule: ```text decoded video frame k == frames.parquet row where video_frame_idx == k ``` Useful files: - `dataset_manifest.parquet`: converted sessions in this dataset root - `sessions//metadata/streams.parquet`: stream IDs and modalities - `sessions//metadata/videos.parquet`: stream-to-video mapping - `sessions//tables/frames.parquet`: authoritative timestamps, frame indices, clock domains, and hashes - `sessions//tables/robot_states.parquet`: robot states, if present - `sessions//metadata/calibration.json`: calibration and transform conventions - `sessions//metadata/validation_report.json`: validation status Downstream reading requires Python, NumPy, PyArrow, and PyAV/FFmpeg-compatible decoders. Camera SDKs are conversion-only dependencies. ## PhysTwin annotation and preprocessing packages The recording contract above is unchanged: `tables/frames.parquet` and `video_frame_idx` remain the timestamp authority, and `dataset_manifest.parquet` catalogs recording sessions only. The packages listed here are additional directories inside existing sessions (`sessions//annotations/windows//` and `sessions//preprocessing//`). Each keeps its original files under `native/` and has a sidecar (`annotation.json` or `artifact.json`) with the file inventory and sha256 digests, source/session/window associations, review status, known gaps and license. They are not recording streams. Files whose exact bytes are already published (at another path here, or upstream) are not uploaded again: a sidecar's `materialized_files` lists each such native path with its sha256 and origin, and `scripts/phystwin_publish.py fetch` recreates it there and checks the digest. Native files smaller than 32 MiB may be stored inside uncompressed tar containers (`/containers/payload_NNN_.tar`). The sidecar's `native_files` still lists every native path with its sha256, its `containers` entry binds `containers/index.json`, and the index gives each file's container and byte offset; `fetch` restores the native layout and checks every digest. Packages planned or re-laid out from November 2026 leave review media (paths with a `review` folder) out of publication; their sidecar's `not_published_review_media` lists those paths, sizes and sha256. ### License scope of these packages Each row's license applies only to the files inside that package directory. It does not license the recordings, session tables, calibration or any other existing file in this repository, whose terms are unchanged (none declared). Notices recorded in a package sidecar for third-party inputs still apply. | Package directory | Kind | Status | License | Scope | |---|---|---|---|---| | `sessions/session_20260921_225524_803572/annotations/windows/window_anchor0471-0708/` | window | accepted | MIT | New project-produced annotation and mask records in this directory only;
