Mail Address Semantics is a voluntary convention for naming people, actors and functions, and for addressing resources, facets, and optional interaction preferences through ordinary email addresses while keeping classification, authority, authentication, equivalence, and delivery implementation explicit and external to the address syntax.

mail-address-semantics

Mail Address Semantics is a voluntary convention for naming people, actors and functions, and for addressing resources, facets, and optional interaction preferences through ordinary email addresses while keeping classification, authority, authentication, equivalence, and delivery implementation explicit and external to the address syntax.

This repo holds the normative MAS v0.1 bundle (mas-v0.1-spec/) and a Python reference experiment (see INTENT.md and workplans/MAS-WP-0002-*).

Parsing is local and deterministic. Discovery is networked. Policy is pure. Delivery remains external.

Layout

Path Role
mas_core/ parser, model, generator, statute (schema + semantic lint + inheritance), discovery, policy
mas_conformance/ Shared corpus: spec fixtures (vendored, drift-tested), property cases, statute cases
mas_cli/ mas parse / explain / discover / lint-statute / test
mas_gateway/ Generic inbound mail → MAS event → HTTP (pipe for MTAs, webhook for providers)
examples/statute/ Static /.well-known/mas for great-service.example + tiny server
examples/ticket_service/ Reference app proving create / correlate / closed / unknown
docs/experiment-review.md Milestone 9 findings

Quick start

uv venv && uv pip install -e '.[test]'
.venv/bin/pytest                       # full suite, offline
.venv/bin/mas test                     # conformance corpus
.venv/bin/mas explain 'ticket!callback@great-service.example' \
    --statute examples/statute/great-service.example/.well-known/mas
.venv/bin/mas lint-statute examples/statute/great-service.example/.well-known/mas

Local end-to-end run:
