For the internal and external data user who needs to understand and connect data, Symbology is a linked data service that allows data mapping and navigation across the Refinitiv information model to enable easier access to data and building of new data workflows.

The Discovery Symbology API is a request/response service and is part of the Refinitiv Data Platform, it is a service to assist users with concordance, navigation and discovery of content. The API enables customers to map from external identifiers to a Refinitiv PermID and to navigate between a wide range of identifiers.

• Map – mapping from an identifier to the corresponding Refinitiv PermID for that entity. For example, mapping an ISIN to an Issue PermID, or mapping a Legal Entity Identifier (LEI) to an Organization PermID. 
• Navigate – navigating between user selected start and end point identifiers (e.g. RIC to ISIN). These start and end points can be at the same or different levels with the hierarchical entity structure i.e. organization, instrument, quote. Entities at different levels in this hierarchy are linked together through relationships enabling users to navigate up and down the structure. Relationships do not need to be specified by the user in this version of the API.

The Discovery Symbology API supports a wide range of market and Refinitiv entity identifiers across multiple asset classes. A full list of the supported identifiers can be found in the Appendix A and via identifier endpoint described later in the document.

The service is available at no additional cost to all customers subscribing to content services through the Refinitiv Data Platform, it is not available on a stand-alone basis.

“ To get started, visit the Refinitiv Data Platform APIs for instructions on how to access the platform services”. In addition, the “Documentation” tab on this page includes a guide that provides details on the News API working environment and supporting resources. It is intended for software engineers and users of RDP who are familiar with the general principles of APIs.
