===Minutes===

  - NLP term table presentation – Noemie {{:projects:workgroups:nlp_wg_meeting_04132016.pdf|}}
        - The note type concept ID is not very useful and should be replaced with a more standardized terminology such as LOINC ontology
        - Replace the current single element with 5 elements (pls see presentation for details)
        - Extend the note source value field to 255 varchar
        - In terms of the type of service, LOINC ontology is very complicated, A flat architecture would be better for the current purpose. Comparison with another institution should be carried out.
        - Date is to be added to the table        - 
        - Include all NLP concepts into one table called Note_NLP/Term_mention Table. This is an intermediate table that can then be linked to other tables in the CDM such as concept
        - Next steps:
          - Schedule another meeting in the following week to continue the discussion
