Interactions Standard

In order to comply with the European Union’s revised Markets in Financial Instruments Directive (commonly referred to as MiFID II), the member firms of RIXML have collaborated to define a new standard – the RIXML Interactions Standard. This standalone standard leverages the existing RIXML Research Standard, re-using and adapting the relevant parts of the existing RIXML schema.

There are various types of interactions:

  • Some take place between one service provider and one service consumer (e.g. an onsite one-on-one meeting)
  • Some take place between one service provider and more than one service consumer (e.g., a conference call)
  • Some take place between one service provider, one or more service consumers, and a third party expert (e.g., a session at a conference)

In all of these cases, the service provider will provide a separate interactions record to each service consumer with information about the event, but it will include ONLY the attendee information that pertains to that consumer. The RIXML Interactions Standard accommodates both one-on-one interactions and more complex ones.

Interactions Data Dictionary

The purpose of the Interactions Data Dictionary is to assist readers in their understanding of the RIXML Interactions Specification. It outlines the approach we took in creating the RIXML Interactions Standard and also explains some fundamental concepts such as XML, object modeling, schemas, etc. Diagrams of the RIXML Interactions object model are included, as are definitions for the elements and attributes.

The RIXML Interactions Schema is the actual XSD file that represents the relationships and components as defined by the object model. This file can also be used to validate instance documents to ensure they are RIXML-compliant.
