Delivering royalty free, open, international, industry and application neutral XML specifications for representing, interoperating, and managing Party (Person/Organisation) Centric Information (Name, Address, Party Profile and Party Relationships)


The Technical Committee was closed by TC Administration on 14 April 2016 and is no longer active.
The CIQ TC specifications has been widely adopted in commercial and governmental applications and has been incorporated into other standards as well. See below for more details.
Archives of its work remain publicly accessible and are linked from this page. OASIS appreciates the efforts of all those who participated in this TC.


On 03 December 2018, TC Admin published Customer Information Quality Specifications Version 3.0 Name (xNL), Address (xAL), Name and Address (xNAL) and Party (xPIL) Committee Specification 02 and added the schemas for Customer Information Quality Party Relationships (xPRL) Specification Version 3.0 CS01.

Both actions had been properly approved by the Technical Committee but never carried out.

More detail can be found in the README files included in http://docs.oasis-open.org/ciq/v3.0/cs02/ and in Table of Contents


September 16, 2013:

The Specifications have been stable since it was released and unless there are any issues identified by the public, there is no intention of releasing any new version. Please send the committee any issues you might have with the specifications. Thank you.

December 06, 2010 - CIQ TC presentation to ISO TC 211/19160:

The TC presented to the ISO TC 211/19160 project team on 6 Dec in Canberra, Australia about its work. ISO TC 211 is working to establish a structured set of standards in the field of digital geographic information.

The Name "Customer Information Quality" is just the operating name of the Technical Committee. The scope of the TC is much broader than "Customer Information". This Committee concentrates on developing global and generic industry standards for managing "Party Centric Information". "Customer" is a type of "Party".

The word "Customer" is used as a generic term and it can be replaced by line of business specific or industry terms (specific to the context) such as: Beneficiary, Business Entity, Citizen, Client, Contact, Guest, Legal Entity, Organisation, Partner, Party, Patient, Prospect, Subscriber, Supplier, Service Provider, Trust, Trustee, etc. All these types of "customer(s)" are a type of "Party".

The objective of the OASIS CIQ TC (formed in 2000) is to deliver a set of XML Specifications for defining, representing, interoperating and managing "PARTY (Person or Organisation) CENTRIC INFORMATION" that are truly open, vendor neutral, industry and application independent, and importantly "Global" (ability to represent international data formats such as different types of party names and addresses used in 241+ countries).

This is the only group in the world that is dedicated to developing Party Information Specifications that are vendor, application, industry and technology neutral, and importantly, open and global.

The CIQ family of specifications are designed to represent party data (e.g. name and address) independent of any culture, geographical location, application or industry at an abstract (simple representation of data - free text format) or detailed (complex representation, i.e. breaking the data into its atomic elements - structured format) level from a data integrity and quality perspective and therefore, is truly a "global" (International) specification for representing party information.

CIQ Specifications enables organisations to have a unified and consistent representation and standardization of their party data (e.g. employee, members, suppliers, partners, customers, etc) and use it to support various application requirements in the organisation that deal with party data (e.g. Master Data Management (MDM), Customer/Party Data Integration, Party identification/recognition/identity management, HR, billing, sales, marketing, data quality and integrity, e-commerce/e-business, party data exchange, postal services, customer/party views, etc). By representing and managing party data consistently using CIQ specifications as the base scheme for an organisation, and extending it to support specific business requirements, unique identitification, integration, standardisation, matching, synchonization and management of quality party information/data is possible.

OASIS CIQ Specifications play a critical role in enabling party oriented software services based on SOA principles to exchange, interoperate and integrate party data in a consistent, standard and open manner between IT systems/applications and processes. It enables "loose coupling of party data" (the business payload) in conjunction with loose coupling of the software services infrastructure (web services-WSDL and other standards).

The figure below shows some of the key use of party centric data in industry and CIQ Specifications help support these variety of applications and industry domains.

The CIQ TC develops XML industry specifications for the following Party entities. Party entities are defined as modular and reusable components (e.g. Party Name only, Party Address only) in the form of XML Schema (for each component).Users can choose the component to implement:

Name of a Party (person or an organisation).

OASIS CIQ specification that provides a standard format to represent the name of a party is "extensible Name Language (xNL)".

A physical location or a mail delivery point.

OASIS CIQ specification that provides a standard format to represent an address/location is "extensible Address Language (xAL)".

A Party could be of two types namely,

  • Person
  • Organisation
    An Organisation could be a company, association, club, not-for-profit, private firm, public firm, consortium, university, school, etc.

    Party centric data consists of many attributes (e.g. Name, Address, email address, telephone, qualifications, occupation, identification details, etc) that are unique to a party. A Customer is of type Party.

    OASIS CIQ specification that provides a standard format to represent party centric data is "extensible Party Information Language (xPIL)".

    Pairwise affiliation or association between two people, between two organisations, or between an organisation and a person

    OASIS CIQ specification that provides a standard format to represent relationships between two or more parties including the roles of the parties involved in the relationship, is "extensible Party Relationships Language (xPRL)".

    xPRL supports chains of interlocking pairwise party relationships, linked by common members.

    CIQ Specifications are open (free to download and use and free from IPRs, Patents, Licenses, and Royalties).

    Adoption of Specifications by Industry Type

    CIQ TC specifications have been widely adopted by different groups around the world (the committee does not track its use as there is no registration process to download the specification and so it is hard to know) and some of the key types of groups are as follows:

  • Governments
  • Financial Organisations
  • Solutions Providers
  • Telecommunication Organisations
  • Product Vendors
  • Retail Organisations
  • Standard Bodies/Groups/Consortiums (e.g. OGC)
  • OASIS Technical Committees (e.g. Election, Emergency, HumanMarkUp, DITA, Tax XML)
  • Address Map (Geospatial) Providers
  • Open Source Community
  • Postal Organisations
  • Manufacturing Organisations
  • Financial Service Providers (e.g. credit cards)
  • Automotive Industry
  • Justice Sector
  • Health

    Google Maps uses OASIS CIQ Specification ast part of its KML. KML and CityGML languages uses OASIS CIQ specifications and both these languages are now "Open Geospatial Consortium (OGC)" Standards.

    Following are a selection of some of the key broad categories of applications that have implemented CIQ TC Specifications:

  • Single/Comprehensive/360 degrees Party View
  • Spatial Information Systems (e.g. Google Earth and Maps)
