pelle · claude · pelle · commit 252c6ea99168 · 2025-08-03T18:27:59.000+02:00
## TAIP Updates - Update TAIP-5 (Transaction Agents) with enhanced agent specifications - Update TAIP-6 (Party Identification) with improved party structure - Update TAIP-11 with additional regulatory compliance features - Update messages.md with latest message format specifications ## Schema Updates - Update agent.json schema with enhanced agent properties and role definitions - Update party.json schema with schema.org Organization and Person attributes - Add support for RFC 8905 PayTo URI format in settlement addresses - Enhance organization attributes: leiCode, legalName, taxId, vatId, mcc, url, logo, description These changes support the fallback settlement addresses feature and improve interoperability with traditional payment systems through RFC 8905 PayTo URIs. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

-In this example, the party's decentralized identifier (DID) or other IRI remains the primary identifier for routing and reference (`@id`). The additional `"lei:leiCode"` field – introduced via the context alias `"lei"` – carries the institution's LEI (here represented by a 20-character code). By using a well-known ontology (Schema.org's `leiCode` property), any party receiving this data can interpret the LEI correctly. The LEI MUST be a 20-character alpha-numeric string conforming to the ISO 17442 standard format (no spaces or delimiters). If the sending institution has an LEI, it **MUST include** it in its party object. If a customer (originator or beneficiary) of a transaction is itself a legal entity (e.g. a business or organization), and has an LEI, that LEI SHOULD also be included in the relevant party object for the originator or beneficiary.

 Per [TAIP-5], institutional participants in a transaction are often represented as *Agents* (e.g. a VASP acting on behalf of a customer). In such cases, the Agent can indicate the legal entity it represents by using the `for` attribute pointing to the Party (entity) object [TAIP-6-Parties]. The Party object for that institution would contain the LEI as shown above. For example, a VASP's Agent identified by a DID could have a corresponding Party entry that includes the VASP's LEI. This indirection allows the agent (which might be a specific service endpoint) to be linked to the broader legal entity identity. Implementations MAY also choose to include the LEI directly as part of an Agent's metadata, but the recommended approach is to use the Party construct so that the legal entity's details are cleanly separated.
