(Optional) Create Manifest and Preferences file.

Manifests control coding scheme metadata and can make adjustments to names and alternate names, versions and many other things that the source normally wants to say about the coding scheme.  This is very useful when the source itself does not supply this information, but the user needs to record it in the terminology service representation.  What follows is a sample manifest file used to update alternate names, language designations and versions.  Details of manifest elements are found in the Administration Guide.



Preference files control how data is loaded and while they don’t add anything to the source the may they can change the representation of a terminology, by making choices as to what is loaded as a property, entity or association from the source.  This preferences file sets root nodes for the terminology and  processes a set of complex properties not handled by the owl processor among other things.  The full preferences definitions are described in the Administration Guide.



Since the Thesaurus may be released as either a "by code" or "by name" formatted source,  preference files can serve the purpose of adjusting the entity code to it's intended place in LexEVS. Here are the differences in an OWL formatted Thesaurus source

A "By Code" formatted Thesaurus:
