semantiva-studio-viewer 0.1.1

A standalone package for interactive visualization of Semantiva pipelines and component hierarchies.

Semantiva Studio Viewer

Web-based viewers and exporters for Semantiva pipelines and component hierarchies.

Install

pip install semantiva-studio-viewer

This provides the semantiva-studio-viewer CLI.

CLI overview

semantiva-studio-viewer --help

Main commands:

• Pipeline inspection

  • serve-pipeline <pipeline.yaml> [--trace-jsonl <trace.jsonl>] [--host 127.0.0.1] [--port 8000]
  • export-pipeline <pipeline.yaml> <output.html> [--trace-jsonl <trace.jsonl>]

• Component inspection

  • serve-components <ontology.ttl> [--host 127.0.0.1] [--port 8000]
  • export-components <ontology.ttl> <output.html>

---

Pipeline inspector

Interactive view of a pipeline:

semantiva-studio-viewer serve-pipeline semantiva-imaging-pipeline.yaml --port 8000

Features:

• Dual-channel layout (data + context).
• Node details: parameters, types, provenance.
• Validation hints from Semantiva’s inspection system.

---

Adding execution traces

Overlay a JSONL trace (from a previous run):

semantiva-studio-viewer serve-pipeline semantiva-imaging-pipeline.yaml \
  --trace-jsonl traces/20250823_run.jsonl

Trace overlay adds:

• Per-node execution summaries (phases, timings, counts).
• Deterministic node↔UUID binding (via positional identity in canonical spec).
• Per-node event APIs: /api/trace/node/<uuid>?offset=&limit=
• Trace metadata at /api/trace/meta and aggregated stats at /api/trace/summary.

You can also export HTML with traces pre-baked:

semantiva-studio-viewer export-pipeline semantiva-imaging-pipeline.yaml \
  pipeline_with_trace.html --trace-jsonl traces/run.jsonl

---

Components browser

Explore Semantiva component ontologies:

semantiva-studio-viewer serve-components semantiva_components.ttl --port 8001

• Classes as nodes
• Subclass edges
• Metadata from docstrings, I/O types, parameters

Export standalone HTML:

semantiva-studio-viewer export-components semantiva_components.ttl components.html

---

Notes

• The inspector tolerates partially invalid configs to aid debugging.
• When traces are present, node→UUID mapping is positional (from canonical_spec); label/FQN fallbacks are used only if necessary.
