Enhance ToxTemp export to support FAIR data principles

[Copilot]

Exported ToxTemp drafts lack the structured metadata, persistent identifiers, open formats, and provenance information needed for downstream discovery and reuse. This adds foundational FAIR data support across all four principles.

Model

• Added uid (UUIDField) to Assay as a stable persistent identifier (urn:uuid:<uid>), with migration 0027_assay_uid

New export types

Type	MIME	Description
jsonld	application/ld+json	JSON-LD with schema.org + Dublin Core context; Q&A embedded as PropertyValue items
zip	application/zip	FAIR bundle: <slug>.jsonld + PROVENANCE.json + LICENSE.txt + README.md

Both types are added to Config.EXPORT_MAPPING / Config.EXPORT_MIME_SUFFIX and excluded from PANDOC_EXPORT_TYPES (handled inline like json).

New API endpoint

GET /api/assay/<uuid>/metadata/ — returns the JSON-LD document for an assay; responds application/ld+json; requires authentication.

Export content improvements

• generate_json_from_assay now includes identifier (UUID), author (name + ORCID when set), keywords, and license
• generate_jsonld_from_assay — schema.org Dataset with @id, creator, hasPart (Q&A), license, provenance timestamps
• generate_provenance_dict — W3C PROV-JSON-inspired record capturing agent, activity, software, and export timestamp
• generate_fair_zip_bytes — in-memory ZIP with all FAIR artefacts

UI

Export dropdowns (overview table + answer page) now include a FAIR Exports section with JSON-LD and FAIR ZIP options.

# Programmatic access example
GET /api/assay/550e8400-e29b-41d4-a716-446655440000/metadata/
# → application/ld+json with @context, @type: Dataset, identifier, creator (+ ORCID), hasPart Q&A, license, prov timestamps

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• postgres_test_for_django
  • Triggering command: /home/REDACTED/.cache/pypoetry/virtualenvs/toxtempassistant-tf6wyKE3-py3.12/bin/pytest /home/REDACTED/.cache/pypoetry/virtualenvs/toxtempassistant-tf6wyKE3-py3.12/bin/pytest myocyte/toxtempass/tests/test_export_security.py myocyte/toxtempass/tests/test_export_errors.py -v (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
