digital-signature-governance-pack 0.1.2

Installable ADR and SPEC extension pack for digital-signature and container governance.

digital-signature-governance-pack

digital-signature-governance-pack is an SSOT Registry pack for digital-signature, advanced electronic signature, container, timestamping, validation, archival, and assurance-language governance.

It gives product, platform, and compliance teams a reusable ADR/SPEC starting point for repositories that need to govern PAdES, XAdES, CAdES, ASiC-S, ASiC-E, validation reports, timestamping, certificate and revocation handling, long-term archival evidence, and constrained eIDAS-facing claim language.

What Is An SSOT Registry Pack?

An SSOT Registry pack is an installable package of governed Architecture Decision Records (ADRs) and Specifications (SPECs) for ssot-registry. The pack supplies reusable decision and requirement documents that downstream repositories can synchronize into their local .ssot registry and link to features, tests, claims, evidence, and releases.

Why This Pack Exists

Digital-signature governance crosses technical standards, cryptographic evidence, validation semantics, archival policy, and assurance wording. Teams need one reviewed source for the decisions and requirements that shape signature-family support, timestamping, validation reports, certificate and revocation handling, long-term evidence, and regulated claim language.

This pack helps teams:

• apply reviewed digital-signature governance requirements across projects
• distinguish signature family, baseline level, container, validation, timestamping, and archival requirements
• keep assurance and regulatory language tied to explicit evidence boundaries
• give product, platform, compliance, and implementation teams stable ADR and SPEC IDs
• connect downstream features, tests, claims, evidence, and releases to shared governance records

Domain Focus

The initial review surface is grounded in TrustSig's signature_and_container_standards_matrix.md and covers:

• ETSI PAdES, XAdES, CAdES, and ASiC family standards
• baseline levels B-B, B-T, B-LT, and B-LTA
• PDF signature standards and ISO PDF extensions
• W3C XML Signature and canonicalization surfaces
• CMS, timestamping, PKIX, OCSP, ERS, XMLERS, and related RFCs
• validation result and validation report modeling
• cryptographic suite policy and algorithm allowlists
• regulatory-language boundaries for eIDAS-related claims

Included ADRs

• adr:0900 digital-signature standards targets are reviewed before governance inclusion

Included SPECs

• spc:0900 digital-signature governance target review

Proposed ADR And SPEC Set

The first detailed proposal is documented in:

Digital Signature ADR/SPEC Proposal

The source standards matrix copied from TrustSig is available at:

Install With uv

Install the pack into a project environment:

uv add digital-signature-governance-pack

Install it alongside the SSOT Registry CLI:

uv add ssot-registry digital-signature-governance-pack

Run without adding dependencies to a project:

uvx --from ssot-registry --with digital-signature-governance-pack ssot --help

Install With The SSOT Registry Pack CLI

Pack-enabled SSOT Registry environments can install and synchronize packs through the pack command surface:

uvx --from ssot-registry ssot pack install digital-signature-governance-pack
uvx --from ssot-registry ssot pack sync . digital-signature-governance-pack

Use With The SSOT Registry CLI

After the pack is installed in the same environment as ssot-registry, synchronize ADRs and SPECs into a target repository:

uv run ssot adr sync .
uv run ssot spec sync .

Review the synchronized governance surface:

uv run ssot adr list .
uv run ssot spec list .
uv run ssot spec get . --id spc:0900

Use the IDs from this pack when linking project features, tests, claims, and release evidence in your local .ssot registry.

Programmatic Usage

from digital_signature_governance_pack import load_document_manifest, read_packaged_document_text

adr_manifest = load_document_manifest("adr")
spec_manifest = load_document_manifest("spec")

print(adr_manifest[0]["id"])
print(spec_manifest[0]["id"])

text = read_packaged_document_text("spec", "SPEC-0900-digital-signature-governance-target-review.yaml")
print(text[:120])
