IDSX v0.2.1: Domain Rules, Audit Semantics and Reference Implementation

Abstract

IDSX v0.2.1 is a software distribution combining the IDSX specification with executable reference implementations for domain-rule validation and normative audit resolution. IDSX complements the buildingSMART Information Delivery Specification (IDS) by addressing engineering requirements involving domain relationships, relationship cardinality, complex connectivity, multi-element rules, and other constraints that cannot be adequately represented using native IDS constructs alone. This release comprises three principal components: IDSX Specification — an XML-based specification defining vocabulary, schema, audit semantics, relationship rules, relationship cardinality, and canonical examples for executable domain rules. The specification version included in this software release remains IDSX v0.2. IDSX Checker — a reference implementation for evaluating IDS and IDSX audit artefacts against IFC information models. It supports machine-readable audit evidence including JSON reports and BCF output. IDSX Normative Audit Profile Resolver — a reference implementation for resolving applicable IDS and IDSX artefacts from normative catalogues, audit profiles, dictionary contexts, and exact normative revisions. IDSX distinguishes consistency-oriented auditing of partial or shared information from completeness-oriented auditing of defined published delivery scopes. This enables the same engineering rule definitions to participate in different information-delivery stages while preserving explicit audit semantics. The specification, checker, and normative resolver are independently reusable components. IDSX is also used as an audit technology by the Energy Domain App, a modular desktop engineering suite that orchestrates engineering information visualization, normative selection, and automated compliance workflows. This record contains the complete IDSX v0.2.1 software source snapshot, including the IDSX v0.2 specification, XML schema, checker, normative resolver, examples, tests, and supporting operational documentation.
