Introduction
The RIXML Coverage Updates Standard provides publishers with a standard vehicle for communicating coverage information to clients and aggregator partners. This schema leverages major elements already defined within the RIXML Research Standard, but also provides a new top-level element and structure for specifying adds, updates, and deletes for pairings of covering entities (organizations and people) and covered entities (asset classes, asset types, security types, issuers, securities, sector/industries, regions, countries, indices, and disciplines).
The RIXML Coverage Updates Standard includes both a set of tags and a set of rules to ensure consistent usage of these tags.
The RIXML Coverage Updates Standard is part of the RIXML Standards Suite, which is also includes the RIXML Research Standard, the RIXML Interactions Standard, and the RIXML Roster Updates Standard.
Current production release: RIXML Coverage Updates Standard 2.5

Schema
There are three XSD files used by the RIXML Coverage Updates Standard. These represent the relationships and components as defined by the object model. These files can also be used to validate individual coverage update records to ensure they are RIXML-compliant.
The following schema files contain the tags used in the RIXML Coverage Updates Standard:
RIXML Coverage Updates main schema – contains the coverage update-specific tags used in the RIXML Coverage Updates Standard
RIXML Common schema – contains the tags used in multiple places in the Coverage Updates Standard and/or used in more than one standard in the RIXML Standards Suite
RIXML Data Types schema – contains the valid values for the enumeration lists used in the RIXML Standards Suite
