Context for continuing work on this dataset. Captures the design decisions and conventions worked out so far.
What this dataset is
Inova-Mk1-Database is the canonical graph dataset of Inova Mk1 SLS printer entities — jobs, print sessions, print profiles, and STL objects. Each entity is its own HuggingFace config; relationships are encoded as ID references in FK-style fields, not via an explicit edges.parquet.
Domain-specific datasets (Inova-Mk1-ASTM, future Inova-Mk1-Telemetry) reference rows here by ID and may embed frozen snapshots of the referenced state when standalone consumption matters more than join-freshness.
Ecosystem
- Upstream raw:
ppak10/SLS4All-Backup— full printer backup (PrintProfiles/,PrintSessions/,Jobs/,Objects/, etc.). This dataset is a curated, structured slice of that. - Downstream domain datasets:
ppak10/Inova-Mk1-ASTM— ASTM mechanical-test specimens (D256/D638/D790) + Instron/TestWorks tensile test results. Rows embed printer-state snapshots (e.g. full print profile inline) so ML consumers don't need to cross-join.ppak10/Inova-Mk1-Telemetry(planned).
- Pattern reference:
ppak10/RocketReviewsuses the same per-entity-config layout (one JSONL per entity, FK fields,scripts/{entity}/01_*.py). Match that pattern when adding configs here.
Architectural decisions
- Per-entity HF configs over nodes+edges parquet. Each entity (
jobs,sessions, etc.) is its ownconfig_namein the README YAML pointing to its owndata/{entity}.jsonl. Consumers doload_dataset("ppak10/Inova-Mk1-Database", "jobs"). The graph is implicit in FK fields, documented in README "Used By" prose. - No git submodules between HF dataset repos. HF's
load_datasetdoesn't follow submodules, so consumers gain nothing; the dependency direction is also wrong (Database is the leaf, not the parent). The umbrella role is filled by the recorder repo (Agentic-Additive-Manufacturing-Process-Optimization), which contains this repo, ASTM, and Telemetry as submodules underdatasets/(allupdate = none— init explicitly); the datasets stay siblings of each other there. - Snapshot vs reference is decided per consumer. This dataset stores references (IDs). Domain datasets choose whether to embed snapshots inline. Default for ML-facing domain datasets: embed the full profile so rows are self-contained.
Directory layout
source/ # raw printer files, mirroring SLS4All app subdirs
Jobs/ # .s4a archives (= zip of STLs + .metadata.json)
PrintSessions/ # per-run session JSONs
PrintProfiles/ # material/energy profile JSONs
Objects/ # STL library (Objects/ASTM/ + supporting)
scripts/{entity}/ # numbered ETL: 01_extract.py, 02_*.py, ...
data/{entity}.jsonl # HF-loadable artifact, one row per record
Scaffold: uv (pyproject.toml, .python-version = 3.10), stdlib only (zipfile, json, re).
File format notes
.s4ais just a zip. Contents: the STLs referenced by the job + a.metadata.json(~22 KB) embedding the full job state. Inspect withunzip -p file.s4a .metadata.json | jq..metadata.jsonPrintProfilefield is already an ID reference, not a snapshot — i.e.AutomaticJob.PrintProfile = {"Id": "..."}. The full profile data lives only in the standalonesource/PrintProfiles/*.jsonfiles.AutomaticJob.NestingState.PrintProfilecan be a different profile fromAutomaticJob.PrintProfile— the nesting was computed against one profile, but a different profile may be assigned at print time. Sessions confirm this: the 2026-05-25.s4ajob is assigned52715389(1 Second Heat Time), but session 1 ran with25682cd2(100% Recycled), matching the nesting profile. Worth surfacing both if it ever matters.

Conventions: light envelope (filename-derived fields at top level), id references surfaced at top level, full raw metadata retained for lossless replay.
IMPORTANT gotcha — object_file_id is per-job, not stable
AutomaticJob.Objects[] and AutomaticJob.ObjectFiles[] are linked only by Name. The same STL file gets a different ObjectFile.Id in each job's metadata — confirmed: d256_impact_specimen.STL is 19b91ed5-… in the 05-25 job and 692f3c49-… in the 05-30 job. The content hash (SHA1) is the stable identity. When building the objects config, key the node by hash, not by object_file_id. object_file_id is useful only as a per-job handle.
Current state
jobsconfig — implemented, 21 rows (scripts/jobs/01_extract.py→data/jobs.jsonl). Covers every 2026-dated print from 2026-05-25 through 2026-07-12 (including non-ASTM Hex Coasters / Nameplates / DragonBurner Cowl side prints).- Two dates carry two jobs each: 2026-06-27 (
D790 and D638 and other objects+Hex Coasters and Nameplates and Benchies) and 2026-06-29 (Debug Run+Nameplate). Downstream lookups need to key byjob_idor filter by object hash — a naive date-key lookup will pick whichever job happened to be extracted last.

Scope note
Current source/ holds all 2026-dated prints from SLS4All-Backup: 21 jobs / 42 sessions / 15 profiles. That's every print the backup has for 2026, including the non-ASTM side jobs (Hex Coasters, Nameplates, DragonBurner Cowl, Bucky). 2025-dated jobs (Bookmarks, Trophy Prints, T-Rex, etc.) are intentionally out of scope — they predate the current ASTM/Telemetry data-collection period.
Loose STL geometry lives in source/Objects/ASTM/ and is still ASTM-only (4 files); the STLs used by each print job are embedded inside the corresponding .s4a archive, so the jobs config is self-contained. If a future objects config wants to enumerate all STLs, it will need to either extract from the .s4a files or import the broader SLS4All-Backup/Objects/ tree.
Backfill trail (chronological):
- 2026-07-11: imported 06-09 Cards + 06-13 Recycled Powder → ASTM batches F ← 06-13, G ← 06-09.
- 2026-07-12: full 2026 sweep + backup refresh through 07-12 → ASTM batches E D790 ← 06-07, H ← 06-24, I ← 06-25, J/J_MB ← 06-27 (the
D790 and D638 and other objectsjob, disambiguated from same-day Hex Coasters via STL-content match in the ASTM_lib).
Adding a new config — recipe
mkdir scripts/{entity}and write01_extract.py(stdlib-only, mirrorscripts/jobs/01_extract.pylayout: ROOT/SOURCE_DIR/OUTPUT_FILE constants,build_row(),main()).- Row shape: top-level filename-derived envelope fields + FK ids + nested
metadatablob. Surface IDs at top level for HF-side filtering; keep the raw blob for lossless replay. - Run script →
data/{entity}.jsonl. - Update
README.mdconfigs:block: addconfig_name: {entity}pointing to the new JSONL. - Add the entity row to the README's Configs table.
