Most data elements will be loaded as either properties or property qualifiers.

A few will be loaded as qualifiers to associations.

...

1. Load coding scheme data as HL7 Rim Metadata from the Model table (rather than the coding scheme data for each HL7 coding scheme).
   1. Mapping of these values will be incomplete: Mapping proposal:

      LexGrid	HL7 RIM
      <codingSchemeName>	<modelID>
      <formalName>	<name>
      <registeredName>	http://www.hl7.org/Library/data-model/RIMImage Removed *
      <defaultLanguage>	en*
      <representsVersion>	<versionNumber>
      <isNative>	0*
      <approximateNumberofConcepts>	Result of count on concept bearing table?
      <firstRelease>	MISSING
      <modifiedInRelease>	MISSING
      <deprecated>	MISSING
      <entityDescription>	<description>
      <copyright>	MISSING

   2. No URN exists and we may need to consider creating one (see entry for registeredName).
2. Locate and load all mappings (such as supportedAssociations and supportedProperties).
   1. Create a supportedHiearchy with a root node of @ on hasSubtype?
3. Iterate through the code system table rows and get each coding scheme.
   1. Create and persist an "@" node in the database
   2. Prepare an artificial "top node" for each coding scheme. (Metadata persisted here as concept properties?) This will result in 250 top nodes.
      • The artificial top nodes will need to have a concept code created for them.
      • Attach to "@" the artificial top nodes as a hasSubtype.
      • Locate the actual top nodes of each coding scheme by querying the relations table to see if they exist as a target code, if not, they are top nodes so attach them to the artificial top node via hasSubtype.
   3. Translate the RRF source property loads to the EMF world.
      • Load the concepts ensuring that the coding scheme name is loaded as a "source" property
      • Load the relations ensuring that the source and target coding scheme data is loaded with the coding scheme name.
4. Concurrent to this process create an updated "HL7 RIM to LexGrid for NCI" mapping from the current Excel mapping document.

LexGrid Text

Wiki MarkupThe text files that can be imported must use the following formats. Items surrounded by <> are required. Items further surrounded by \ [\] are optional. \t represents a tab - the default delimiter - however other delimiters may be used.

Lines beginning with # are comments.
