Architech Suite · Runtime · V1 Early Partner Edition
MERIDIAN unifies the standards IFC 2x3 / 4 / 4.3, AAS, W3C WoT, Brick, Project Haystack, SAREF, SOSA/SSN, CityGML 3.0, IndoorGML and twenty-two industrial protocols — from the BACnet sensor to multi-region cluster orchestration. Written in Rust from scratch on the public specifications of ASHRAE, OASIS, IEC, IEEE, OMA, ICAO, with no copyleft dependency, 100% GREEN IP. From the 50 MB gateway to the petabyte datacenter, the same code.
Runtime
The industrial IoT market lacks a runtime that simultaneously covers BIM schemas, semantic ontologies, protocol connectivity, sovereign identity, constrained edge and datacenter distribution. MERIDIAN is that runtime.
A fifty-megabyte gateway on Raspberry Pi 4 or a Raft cluster across one hundred nodes ingesting 100 million events per second — the same Rust binary, the same API, the same trust contract. No fork. No drift. The runtime folds onto an ESP32-S3 and scales to multi-region clusters with semantic and geographic sharding.
Built to become the code foundation that IoT integrators can consume as an SDK (pip install meridian, @meridian/core npm, @meridian/wasm, meridian.h via C ABI) or as a gRPC service. Functionally outperforms IfcOpenShell, Eclipse BaSyx, Brick reference, and the proprietary SDKs of Siemens, Honeywell, JCI, Schneider on their intersection.
Architecture
Each layer independent, testable, releasable. Forty Cargo crates in a single workspace.
EXPRESS code generator ISO 10303-11. IFC 2x3 / 4 / 4.3 SPF + XML + JSON + HDF5, mvdXML validation, version conversion. AAS IEC 63278 + AASX. W3C WoT Thing Descriptions. Semantic bridge SOSA/SSN ↔ Brick ↔ Haystack ↔ SAREF ↔ AAS ↔ WoT.
Arena allocator, ID interning, semantic + spatial + temporal indexing. Pluggable persistence: RocksDB (edge), Postgres + pgvector (cloud), S3 (cold). Merkle versioning, append-only timeline. SPARQL-inspired DSL with spatial and temporal extensions.

Multi-node coordination via Raft for critical metadata. Semantic and geographic sharding. Multi-region replication with causal consistency. Federated query planner across clusters. HyParView + SWIM gossip for discovery. QUIC backpressure. Native OpenTelemetry + Prometheus observability.
Bindings
Embedded in your stack (in-process, zero network hop) or exposed as a network service — your choice, on the same Rust core.
PyO3 bindings, ABI 3.10 / 3.11 / 3.12 / 3.13, numpy interop for time-series and geometry. Drop-in replacement for IfcOpenShell in data science sidecars and notebooks.
napi-rs bindings, full .d.ts types, compatible with Node 18 / 20 / 22 / Bun / Deno. For Fastify backends, BullMQ workers, Cloudflare edge functions.
wasm-bindgen for browser (client-side IFC parsing) and wasm32-wasi for serverless (Cloudflare Workers, AWS Lambda). SharedArrayBuffer for browser multi-threading.
cbindgen, symbols prefixed meridian_*, stable documented ABI. Linkage from C, C++, .NET (P/Invoke), Go (cgo), Java (JNI), Swift.
tonic service exposing the public API, bidirectional streaming for subscriptions, server reflection, health check protocol, rustls TLS. Client in any language.
Command-line tool: meridian ifc read, aas read, wot fetch, query, edge start, cluster join. Human or JSON output.
Connectivity
Each driver written in pure Rust against the public specification of its standards body. No borrowing from copyleft open-source code. Hot-pluggable, optionally WASM-sandboxed.
Schemas
A single sensor or piece of equipment represented in IFC, AAS, WoT TD, Brick, Haystack, SAREF — bidirectional conversion, preserved semantics, verified round-trip.
Performance
V1.0 targets, measured by publishable Criterion benchmarks, in direct competition with IfcOpenShell, Eclipse BaSyx, Brick reference.
Trust
Every event signed. Every mutation hash-chained. Every device identified by verifiable hardware attestation. Audit anchorable on-chain.
Issuance, verification, presentation of verifiable credentials. DID methods: did:architech (anchored chain 79283), did:web, did:key, did:ion. Selective disclosure via BBS+ signatures. Zero-touch provisioning: Matter Commissioning, LwM2M Bootstrap.
TPM 2.0 on Linux and Windows. Apple Secure Enclave on macOS and iOS. Intel SGX. ARM TrustZone via OP-TEE. Key rotation, revocation, recovery. Secure factory provisioning.
Ed25519 RFC 8032 and Ed448 for the present. CRYSTALS-Dilithium and CRYSTALS-Kyber for the quantum future. Crypto-agile pipeline: switch on rotation, no break.
Merkle append-only hash-chain for internal audit. OpenTimestamps bridge for Bitcoin anchoring. eIDAS Article 26 bridge for advanced electronic signature. Optional: anchoring on Architech chain.
Status
Seven sequential phases, acceptance criteria cargo-deny + criterion bench. No phase passes until criteria are green.
