Taxonomy interoperability, without the mapping-table burden.
Integrate ACT-IDs once and read every activity across 20+ official taxonomies and the market frameworks — instead of building and maintaining your own cross-taxonomy mapping tables.
Why data and software vendors use Act IDs
Data providers, analytics platforms, and portfolio management systems all face the same problem: every issuer describes financed activities differently, and every client wants that activity read back in a different taxonomy. Building and maintaining your own cross-taxonomy mapping tables is time-consuming, inconsistent across teams, and never complete.
Act IDs provide a stable, open reference layer that lets you map issuer descriptions once — and read the resulting activities across 20+ official taxonomies and the market frameworks, for your entire client base.
Integration
Map each issuer's use-of-proceeds categories to Act IDs in your ingestion pipeline. Once mapped, your entire dataset gains a consistent activity dimension that all clients can use.
Interoperability
When your data uses Act IDs, it aligns with other products that do too. Clients working across multiple systems — portfolio management, ESG analytics, reporting tools — benefit from consistent identifiers throughout their stack.
Mapping and lineage
Act IDs come with tracked mappings to major frameworks and taxonomies. Use these as a starting point for your own classification work — with full citation and provenance built in.
Licensing
Act IDs are freely referenced in disclosures, research, and public reporting. Commercial vendors integrating Act IDs into products sold to clients obtain a straightforward vendor licence.
