**Topics**
  * Reviewed Dmytry's latest progress on the NAACCR ingestion script.
    * Discussed the possibility of moving NAACCR schemas into a new structure to keep the CONCEPT.concept_code clean (not contain anything NOT in NAACCR source data).  But we decided for version 1 we would include NAACCR schemas in the vocabulary, and include NAACCR schema IDs in site-dependent NAACCR items and NAACCR Item Codes.  This means that ETL developers will have to know to use Rimma's ETL code to map NAACCR data into OMOP.
    * Agreed that mapping NAACCR schemas to ICD site/histology combinations is a must have for version 1 of NAACCR ingestion.  Rimma's ETL SQL will not work without it.
    * Discussed whether NAACCR site-dependent variables should be duplicated across schemas.  Dmytry's first version of NAACCR ingestion is duplicating them.  We agreed that they should not.  Dmytry said he can dedupe them.
    * Resolved "Curate NAACCR Items/Item Codes and OMOP domains":  [[https://github.com/OHDSI/OncologyWG/issues/26]]
    * Resolved "How should we handle long CONCEPT.concept_name entries that exceed 255 characters coming from NAACCR?": [[https://github.com/OHDSI/OncologyWG/issues/28]]
    * Discussed: How should we handle 'Numeric' NAACCR items that define numeric ranges?:https://github.com/OHDSI/OncologyWG/issues/26
    * Resolved "How should we handle NAACCR provenance concepts?": [[https://github.com/OHDSI/OncologyWG/issues/32]]
    * Discussed 'How should we handle versions of staging variables?  For both TNM and AJCC variables?': [[https://github.com/OHDSI/OncologyWG/issues/31]]
    * Resolved "Should we record dates as a separate measurement record.(e.g. Date regional lymph node dissection NAACCR #682)?":https://github.com/OHDSI/OncologyWG/issues/33
    * Resolved "How do we handle different versions of NAACCR?": [[https://github.com/OHDSI/OncologyWG/issues/34]]
