As part of developing a new reference set it should be created and identified as part of the Edition that it belongs to.
When creating a new reference set, the organization developing the reference set will need access to a namespace in order to generate SCTIds. Within their namespace, a moduleId concept (with an FSN and Preferred Term) should be added, placed in the 900000000000443000 |Module (core metadata concept)|subhierarchy within the metadata, for each authoring organization.
To specify any reference set it is necessary to identify the reference set by creating a concept and name the reference set by associated descriptions. The concepts should be a subtype of the relevant reference set type concept in the foundation metadata hierarchy. This could for example be as a descendant of the 446609009 |Simple type reference set (foundation metadata concept)|, or the 900000000000512005 |Query specification type reference set (foundation metadata concept)|. The latter is used for intensional reference set definitions. Following table shows the steps to follow when creating a new reference set.
